The mediating role of child delay of gratification in the link between early and prolonged poverty exposure and adolescent allostatic load

Early and prolonged exposure to poverty disrupts biological processes associated with the body's stress response system, leading to long-term negative health outcomes, including obesity, autoimmune disorders, and cardiovascular disease. Allostatic load (AL), a composite measure of chronic stress on the body, is a robust predictor of subsequent health outcomes. However, developmental research examining the associations of early poverty exposure with AL in adolescence, as well as the underlying mechanisms of influence is limited. Early poverty exposure also impedes healthy development of child self-regulation, which may increase risk for high AL in adolescence, but this mechanistic pathway has not yet been tested. We used data from the national Study of Early Child Care and Youth Development (SECCYD) to examine the longitudinal associations between prolonged poverty exposure in early childhood (0-3 years) and AL in adolescence (age 15). We also tested the mediating role of child delay of gratification, a behavioral measure of self-regulation (at age 54 months), in the potential association between early poverty exposure and adolescent AL. Accounting for model covariates (i.e., child biological sex and race-ethnicity) and individual differences in child delay of gratification, early and prolonged poverty exposure was significantly associated with higher AL at age 15. The indirect effect through child delay of gratification was not significant, but the individual pathways of the indirect effect were significant, and the overall direct association of early poverty exposure with adolescent AL was significant. Our findings show that prolonged exposure to poverty in early childhood (0-3 years) can have significant negative associations with both child delay of gratification (at 54 months) and AL (at age 15). Given that the detrimental impacts of poverty exposure can be detected at an early age, targeted prevention efforts (e.g., anti-poverty programs such as cash assistance programs) may be able to offset some of the risks of early poverty exposure on self-regulation and AL.

Reactive and control processes in the development of internalizing and externalizing problems across early childhood to adolescence

Reactive and control processes - e.g., negative emotionality and immediacy preference - may predict distinct psychopathology trajectories. However, externalizing and internalizing problems change in behavioral manifestation across development and across contexts, thus necessitating the use of different measures and informants across ages. This is the first study that created developmental scales for both internalizing and externalizing problems by putting scores from different informants and measures onto the same scale to examine temperament facets as risk factors. Multidimensional linking allowed us to examine trajectories of internalizing and externalizing problems from ages 2 to 15 years (N = 1,364) using near-annual ratings by mothers, fathers, teachers, other caregivers, and self report. We examined reactive and control processes in early childhood as predictors of the trajectories and as predictors of general versus specific psychopathology in adolescence. Negative emotionality at age 4 predicted general psychopathology and unique externalizing problems at age 15. Wait times on an immediacy preference task at age 4 were negatively associated with age 15 general psychopathology, and positively associated with unique internalizing problems. Findings demonstrate the value of developmental scaling for examining development of psychopathology across a lengthy developmental span and the importance of considering reactive and control processes in development of psychopathology.

If They Won't Know, I Won't Wait: Anticipated Social Consequences Drive Children's Performance on Self-Control Tasks

This research evaluated the hypothesis that the act of offering an incentive produces anticipated social benefits that are distinct from the benefits associated with the incentive itself. Across three preregistered studies, 3- to 5-year-old children in China (total N = 210) were given an opportunity to wait for an additional sticker (Studies 1 and 3) or an edible treat (Study 2). Rewards were dispensed via a timer-controlled box that allowed the experimenter's apparent ability to learn how long children waited to be manipulated experimentally. Children waited only about half as long when they believed the experimenter would not find out how long they waited. When children were offered three prizes for waiting, anticipated social benefits still drove behavior at least as much as the reward. The findings demonstrate that children as young as 3 years are sensitive to anticipated social rewards when responding to offers of incentives.

Using an episodic specificity induction to improve children's future thinking

Episodic future thinking (EFT) is the ability to subjectively pre-experience a specific future event. Future-oriented cognition in young children positively predicts physical health and financial status later in life. Can EFT be improved in children, even temporarily? Developmental research emphasizes the importance of thinking about one's own near future to enhance EFT, whereas research in adults suggests benefits reside in constructing a richly detailed event. We bridged the two perspectives to examine whether a procedure, the "episodic specificity induction" (ESI), could be adapted to encourage an episodic mode of thinking in children, benefitting performance on a variety of subsequent EFT tasks. The present study implemented a child-friendly ESI in which children mentally simulated a future event and were probed for specific details about it. We randomly assigned 66 children aged 6 and 7 years to one of two conditions: (1) ESI, in which children imagined "having breakfast tomorrow" in detail, describing surroundings, people, and actions, or (2) a Control condition (i.e., no construction), in which children simply viewed and described a picture of another child having breakfast. Children then completed a series of future thinking tasks assessing prospective memory, recollection/imagination of events, delay of gratification, and planning. Our ESI was successful in promoting the construction of a detailed event, and subsequently increasing the number of details of recollected and imagined events on an outcome task as compared to a control condition. Nonetheless, the effect of ESI was smaller than expected - a finding that fits with recent work suggesting that such interventions may be too cognitively taxing for young children and/or that benefits may hinge on further development in episodic processes. We discuss possible modifications to the induction and implications for EFT amelioration in young children.

The relationship between performance appraisal interval and employees' proactive working behavior - analysis based on time-gain effect and time-loss effect

Introduction

Performance appraisal is the most widely motivation means for employees' initiative and work improvement. As a large number of organizations are moving from traditional annual performance appraisal to more frequent appraisals, there is little research to compare the motivational effect of different performance appraisal intervals.

Methods

We explore the relationship between performance appraisal interval (PAI) and positive work behavior (PWB) as well as how to improve the relationship between them. Drawing from the psychological momentum (PM) theory, we constructed a model of the dual effect (the time-gain effect and time-loss effect) of PAI on PWB as well as their boundary conditions.

Results

A cross-level analysis of 622 employees in 57 teams indicated that: (1) PAI exerted a positive but marginal decreasing effect on delay of gratification (DG), and then increase PWB indirectly (i.e., the time-gain effect). (2) PAI exerted a positive and marginal increasing effect on perceived uncertainty (PU), and then decrease PWB indirectly (i.e., the time-loss effect). (3) According to the additive principle of the benefit and cost proposed by Hanns et al (2016), the addition of the time-gain effect and time-loss effect leads to an inverted U-shape effect of PAI on PWB. (4) Supervisor developmental feedback (SDF) moderated the inverted U-shape effect of PAI on PWB.

Discussion

This research enriches the application of PM theory in performance appraisal research, advances employee proactivity research from a perspective of organizations' time mechanisms, and also provides a theoretical basis for leaders to adopt developmental feedback as an optimization strategy.

Italian Validation of the Delaying Gratification Inventory in Adolescents

The delay of gratification (DoG) is defined as the willingness to forego immediate satisfaction to achieve greater long-term gratification. This ability is essential in adolescence, as its development is crucial against desirable versus undesirable behaviors. This study investigated the psychometric proprieties of the Delaying Gratification Inventory (DGI) in Italian adolescents. A total of 621 Italian adolescents, ranging from 14 to 17 years old (M = 15.92, SD = 1.05; 47.7% boys), participated in the study. Confirmatory factor analysis identified a four-factor structure (delay of gratification concerning Food, Social Interaction, Money, and Achievement). The reliability of the Italian DGI was acceptable. Measurement invariance across gender was supported. Boys reached a higher DoG score in the Food subscale and a lower score in the Social Interaction and Achievement subscales than girls. Moreover, the Italian DGI dimensions were all positively correlated with self-control and prosocial behavior. Except for the Social Interaction subscale, positive correlations were found between the Food, Money, and Achievement subscales and self-esteem. The present findings suggest that the Italian DGI could be used for assessing DoG ability, a key regulatory ability that promotes healthy behaviors in adolescence.

Pre-pandemic family resources and child self-regulation in children's internalizing problems during COVID-19: a multi-level social-ecological framework for emotional resilience

Introduction

Children's psychological adjustment to adverse events can be determined by multiple risk and resilience factors. This study explored multi-level protective factors against children's internalizing problems and investigated the mechanism regarding how diverse environmental and child-level resources influence children's mental health in the context of COVID-19.

Methods

Our participants included a nationally representative sample of 2,619 young children (48.3% girls) and their primary caregivers (95.1% mothers) in Singapore. They were a subset of the participants in the Singapore Longitudinal Early Development Study (SG LEADS). Data were collected over two waves-before the outbreak of the COVID-19 pandemic (Wave 1) when these children aged 3 to 6, and during the second year of the pandemic (Wave 2). Primary caregivers completed measures of verbal cognitive ability, self-control, economic stress, and positive and negative parental control in Wave 1. Children's self-regulation was assessed by the Delay of Gratification task in Wave 1, and their internalizing problems were rated by their primary caregivers in both waves. Other pre-pandemic family and community characteristics were collected as covariates. Structural equation modeling was performed.

Results

Pre-pandemic parental resources (i.e., verbal cognitive ability, self-control, and low economic stress) predicted children's fewer internalizing problems during the pandemic and less aggravation of internalizing problems from before to during the pandemic, through more positive parental control (i.e., limit setting) and less negative parental control (i.e., harsh discipline). Moreover, children's self-regulation during early childhood was predicted by their primary caregivers' verbal cognitive ability and self-control, as well as positive parental control. Early childhood self-regulation further alleviated the aggravation of internalizing problems over time. Among the covariates, parental education, family income, parental psychological well-being, living with both parents, having a live-in domestic helper, and neighborhood quality also longitudinally predicted fewer child internalizing problems.

Discussion

Our findings underscore the importance of nurturing children's emotional resilience under adverse and uncertain circumstances by boosting protective factors in their social-ecological system, including community-, family-, parent-, and child-level resources.

Construal level among poor children: Executive function implications

Poverty impedes children's executive function (EF). Therefore, it is necessary to mitigate the negative effect of poverty by developing efficient interventions to improve poor children's cognitive function. In three studies, we examined whether high-level construals can improve EF among poor children in China. In Study 1, we observed a positive relationship between family socioeconomic status and children's EF, which was moderated by construal level (n = 206; M _age  = 9.71; 45.6% girls). In Study 2a, we experimentally induced high- versus low-level construals and found that poor children with high-level construals exhibited better EF than those with low-level construals (n = 65; M _age  = 11.32; 47.7% girls). However, the same intervention did not affect the performance of affluent children in Study 2b (n = 63; M _age  = 10.54; 54% girls). Moreover, we found that the interventional effects of high-level construals improved the ability of children living in poverty to make healthy decisions and delayed gratification in Study 3 (n = 74; M _age  = 11.10; 45.9% girls). These findings may have implications for using high-level construals as an effective intervention to improve poor children's EF and cognitive capacity.

Parent Training for ADHD: No Generalization of Effects From Clinical to Neuropsychological Outcomes in a Randomized Controlled Trial

OBJECTIVE

We examined whether neuropsychological function in ADHD can be improved by the New Forest Parenting Programme (NFPP), that combines standard parenting strategies with self-regulatory skills training, or predict ADHD and quality of life (QoL) treatment effects.

METHOD

Participants were 93 medication-naive preschool children with ADHD (3-7 years) randomized to either NFPP (n = 49) or treatment as usual (TAU; n = 44) in a recent randomized trial. Laboratory measures of executive function, reaction time variability, and delay of gratification were collected along with parent ratings of ADHD and QoL at baseline and post treatment. Ratings were collected again at 3-month follow-up.

RESULTS

NFPP did not improve neuropsychological function (compared to TAU), and baseline neuropsychological function did not predict treatment-related ADHD or QoL effects.

CONCLUSION

Although NFPP includes a neuropsychological training element and has been shown to improve several clinical outcomes, it did not improve the neuropsychological functions it targets.

Temporal expectations in delay of gratification

We examined how temporal expectations influence preference reversals in a delay of gratification task for rats based on a hypothesis of Rachlin (2000), who suggested that preference for a larger-later reward may shift in favor of a smaller-immediate reward as a result of changes in when that larger reward is expected. To explore Rachlin's hypothesis, we preexposed two groups of rats to the delays associated with a larger-later reinforcer from a delay of gratification task. One group experienced the delays as a function of their choices in an intertemporal choice task and the other group experienced delays yoked from the first group (independent of their behavior) in an exposure training procedure. In addition, we included a third group of rats that were not exposed to delays during preexposure training as a comparison to the other two groups. Overall, the two groups of rats that experienced delays during preexposure training tended to make fewer defection responses than the comparison group during the delay of gratification task. Consistent with Rachlin's hypothesis, our results suggest that temporal learning may influence preference reversals in a delay of gratification task, providing a number of future directions for research in this area.

Cultures Crossing: The Power of Habit in Delaying Gratification

Resisting immediate temptations in favor of larger later rewards predicts academic success, socioemotional competence, and health. These links with delaying gratification appear from early childhood and have been explained by cognitive and social factors that help override tendencies toward immediate gratification. However, some tendencies may actually promote delaying gratification. We assessed children's delaying gratification for different rewards across two cultures that differ in customs around waiting. Consistent with our preregistered prediction, results showed that children in Japan (n = 80) delayed gratification longer for food than for gifts, whereas children in the United States (n = 58) delayed longer for gifts than for food. This interaction may reflect cultural differences: Waiting to eat is emphasized more in Japan than in the United States, whereas waiting to open gifts is emphasized more in the United States than in Japan. These findings suggest that culturally specific habits support delaying gratification, providing a new way to understand why individuals delay gratification and why this behavior predicts life success.

Testing delay of gratification in rats using a within-session increasing-delay task

In delay discounting, preference reversals refer to shifts in preference from a larger-later reward to a smaller-sooner reward. Steep hyperbolic discounting predicts a preference reversal when a smaller-sooner and larger-later reward both become temporally proximal; prior research is consistent with this prediction. Hyperbolic discounting does not predict a preference reversal, however, after an individual chooses a larger-later reward over a smaller-immediate reward; prior research is inconsistent with this prediction. We sought to replicate and extend these findings using a delay of gratification task in rats. The task included a defection response which allowed rats to reverse their preference after choosing a larger-later sucrose reinforcer to instead obtain a smaller-immediate sucrose reinforcer. In Experiment 1, we found that rats would defect on their choice of the larger-later reinforcer, systematically replicating prior research. We also found that experience on the delay of gratification task led to decreases in defection responses. In Experiment 2, we found that prior experience on an intertemporal choice task, with no opportunity to defect, also led to few defection responses on the delay of gratification task. We discuss our findings in the context of whether inhibitory control or temporal learning could be involved in delay of gratification.

Associations Among Food Delay of Gratification, Cognitive Measures, and Environment in a Community Preschool Sample

Much of the work on the development of appetite self-regulation in early childhood employs tasks assessing Delay of Gratification (DoG). While this skill is thought to rely on "cool" cognitive processes like effortful control, executive functioning, and self-regulation, demonstration of how laboratory measures of food DoG relate to common assessments of those cognitive processes in community samples of children is needed. This study presents secondary data investigating the associations between two laboratory tasks of food DoG, the Snack Delay and Tongue Tasks, and an array of laboratory and parent-report cognitive measures in a sample of 88 children ages 3-6 (M age = 4.05, SD = 0.76), as well as how four measures of the child's environment were associated with food DoG. Results indicated that both measures of food DoG were positively correlated with performance on the cognitive tasks, with stronger associations observed for the Tongue Task. Family income was positively associated with food DoG as measured by the Tongue Task, and child negative life events in the past year were negatively correlated with food DoG as measured by the Snack Delay Task. These findings present the pattern of associations between cognitive tasks and food DoG, the development of which may be meaningfully affected by specific aspects of family environment.

What Influences the Financial Literacy of Young Adults? A Combined Analysis of Socio-Demographic Characteristics and Delay of Gratification

The current economic landscape is complex and globalized, and it imposes on individuals the responsibility for their own financial security. This situation has been intensified by the COVID-19 crisis, since short-time work and layoffs significantly limit the availability of financial resources for individuals. Due to the long duration of the lockdown, these challenges will have a long-term impact and affect the financial well-being of many citizens. Moreover, it can be assumed that the consequences of this crisis will once again particularly affect groups of people who have already frequently been identified as having low financial literacy. Financial literacy is therefore an important target for educational measures and interventions. However, it cannot be considered in isolation but must take into account the many potential factors that influence financial literacy alone or in combination. These include personality traits and socio-demographic factors as well as the (in)ability to defer gratification. Against this background, individualized support offers can be made. With this in mind, in the first step of this study, we analyze the complex interaction of personality traits, socio-demographic factors, the (in-)ability to delay gratification, and financial literacy. In the second step, we differentiate the identified effects regarding different groups to identify moderating effects, which, in turn, allow conclusions to be drawn about the need for individualized interventions. The results show that gender and educational background moderate the effects occurring between self-reported financial literacy, financial learning opportunities, delay of gratification, and financial literacy.

Inhibitory Dimensions and Delay of Gratification: A Comparative Study on Individuals with Down Syndrome and Typically Developing Children

While previous research on inhibition in people with Down syndrome (DS) reported contradictory results, with no explicit theoretical model, on the other hand, a more homogeneous impaired profile on the delay of gratification skills emerged. The main goal of the present study was to investigate response inhibition, interference suppression, and delay of gratification in 51 individuals with DS matched for a measure of mental age (MA) with 71 typically developing (TD) children. Moreover, we cross-sectionally explored the strengths and weaknesses of these components in children and adolescents vs. adults with DS with the same MA. A battery of laboratory tasks tapping on inhibitory sub-components and delay of gratification was administrated. Results indicated that individuals with DS showed an overall worse performance compared to TD children on response inhibition and delay of gratification, while no differences emerged between the two samples on the interference suppression. Additionally, our results suggested that older individuals with DS outperformed the younger ones both in response inhibition and in the delay of gratification, whereas the interference suppression still remains impaired in adulthood. This study highlights the importance of evaluating inhibitory sub-components considering both MA and chronological age in order to promote more effective and evidence-based training for this population.

The role of oxytocin in delay of gratification and flexibility in non-social decision making

Oxytocin is well-known for its impact on social cognition. This specificity for the social domain, however, has been challenged by findings suggesting a domain-general allostatic function for oxytocin by promoting future-oriented and flexible behavior. In this pre-registered study, we tested the hypothesized domain-general function of oxytocin by assessing the impact of intranasal oxytocin (24 IU) on core aspects of human social (inequity aversion) and non-social decision making (delay of gratification and cognitive flexibility) in 49 healthy volunteers (within-subject design). In intertemporal choice, patience was higher under oxytocin than under placebo, although this difference was evident only when restricting the analysis to the first experimental session (between-group comparison) due to carry-over effects. Further, oxytocin increased cognitive flexibility in reversal learning as well as generosity under conditions of advantageous but not disadvantageous inequity. Our findings show that oxytocin affects both social and non-social decision making, supporting theoretical accounts of domain-general functions of oxytocin.

Delay of Gratification Predicts Eating in the Absence of Hunger in Preschool-Aged Children

Poor ability to regulate one's own food intake based on hunger cues may encourage children to eat beyond satiety, leading to increased risk of diet-related diseases. Self-regulation has multiple forms, yet no one has directly measured the degree to which different domains of self-regulation predict overeating in young children. The present study investigated how three domains of self-regulation (i.e., appetitive self-regulation, inhibitory control, and attentional control) predicted eating in the absence of hunger (EAH) in a community sample of 47 preschool-aged children (M age = 4.93, SD = 0.86). Appetitive self-regulation, as measured using a delay of gratification task, was significantly and negatively associated with EAH 1 year later (p < 0.5). Measures of inhibitory and attentional control did not significantly predict EAH. These results suggest that food-related self-regulation may be a better predictor of overeating behaviors than general measures of self-regulation.

A Meta-Analytic Review of Sex Differences on Delay of Gratification and Temporal Discounting Tasks in ADHD and Typically Developing Samples

Objective: To examine whether males and females with ADHD differ in their preferences for delayed rewards, since there is some evidence that suggests a sex difference with typically developing (TD) samples. Method: We used meta-analyses to examine sex differences on delay of gratification and temporal discounting tasks in both TD and ADHD samples. We identified 28 papers with 52 effect sizes for children and adults, and calculated the average effect size for sex comparisons within TD and ADHD samples. Results: The estimated mean difference between TD males and TD females was negligible, but males with ADHD were more likely to choose the larger delayed rewards than females with ADHD. Meta-regressions indicated that task type, age, and reward type did not significantly predict sex differences. Conclusion: These findings suggest that females referred for ADHD may make less adaptive choices by preferring smaller immediate rewards over larger delayed rewards more often than males with ADHD. Implications of our findings are discussed.

Evaluating a Board Game Designed to Promote Young Children's Delay of Gratification

OBJECTIVE

Delay of gratification, or the extent to which one can resist the temptation of an immediate reward and wait for a larger reward later, is a self-regulatory skill that predicts positive outcomes. The aim of this research was to conduct initial tests of the effects of a board game designed to increase children's delay of gratification via two experimental studies.

METHODS

Preschool children were randomized to play the study game or a control game. In Study 1, there were 48 children in the analytic sample, with a mean age of 4.81 ± 0.55 years; Study 2 included 50 children (M = 4.02 ± 0.76 years). Delay of gratification was assessed during the study game, as well as before and after game play sessions using the Marshmallow Test.

RESULTS

In both studies, the intervention group's likelihood of delaying gratification during the study game increased across game-play sessions (p < 0.05). In Study 1, the intervention group also increased wait times during the Marshmallow Test versus controls (p = 0.047). In Study 2, there was no effect on Marshmallow Test wait times.

CONCLUSION

Results provide some initial evidence supporting potential efficacy of a board game designed to increase delay of gratification. Future research can clarify: (1) which components of game play (if any) are linked with broader changes in delay of gratification, (2) impacts of this intervention in more diverse samples, and (3) whether experimental manipulation of delay of gratification affects outcomes like achievement and weight, which have been linked to this skill in observational studies.

Time Perspectives and Delay of Gratification - The Role of Psychological Distance Toward the Future and Perceived Possibility of Getting a Future Reward

Purpose

This study investigated how an individual’s time perspective of the present and the future affects the delay of gratification, using the construal level theory. In addition, the mechanisms that influence the time perspective on the delay of gratification were examined through the mediating roles of the psychological distance and the perceived possibility of getting a future reward.

Participants and Methods

One hundred twenty university students completed the Korean version of the Swedish Zimbardo Time Perspective Inventory (S-ZTPI) and performed a Temporal Discounting task to aid in the evaluation of their ability to delay gratification. Their psychological distance to the future and perceived possibility of getting a future reward were measured using the visual analogue scale.

Results

The results showed that once the Present-Hedonistic and Future-Negative from among the six-time perspectives increased, and the ability to delayed gratification decreased. On the other hand, once the Future-Positive time perspective increased, the ability to delayed gratification increased. Only the psychological distance for 9 months was associated with time perspective and the mediation effect was not significant. Present-Hedonistic time perspective negatively predicted the perceived possibility of getting a future reward and the delay of gratification. The perceived possibility of getting a future reward fully mediated the relation between the Future-Negative time perspective and the delay of gratification.

Conclusion

These findings suggest that problems involved with the delay of gratification (such as smoking, addiction, and binge eating behavior) are more likely to occur in people who have high Present-Hedonistic and Future-Negative time perspectives, because these time perspectives lead to a lower perceived possibility of getting a future.

Delay of Gratification as Reputation Management

Although delay-of-gratification tasks have long been used as measures of self-control, recent evidence suggests that performance on these tasks is also driven by rational decision processes. The present research examined whether the effects of rational decision processes extend beyond costs and benefits embedded in the task itself to include anticipated consequences for the child's reputation. Across two studies, 3- and 4-year-olds from China (N = 273) were assigned to a standard delay-of-gratification condition or to a reputation condition in which they were told that their teacher or a peer would find out how long they had waited. Children waited longer in the reputation conditions and longer in the teacher condition than in the peer condition. This is the first evidence that children's performance on a delay-of-gratification task is sensitive to reputational concerns and to the identity of potential evaluators of their behavior.

Early delay of gratification predicts later inhibitory control and academic performance in children with prenatal alcohol exposure

Fetal alcohol spectrum disorder (FASD) affects 2-5% of the children in the United States. In the preschool age-range, inhibitory deficits frequently manifest as impaired ability to delay gratification, which is associated with deficits in cognitive flexibility in these children. The goal of this longitudinal study was to determine whether the ability to delay gratification in preschool children with FASD is (1) associated with broader manifestations in temperament and behavior; (2) predictive of later inhibitory control, cognitive flexibility and working memory in middle childhood; and (3) predictive of later parent-reported behavioral problems and school functioning in middle childhood. Forty-seven children with FASD, ages 2.5-5 years were administered a delay of gratification task in which they chose between receiving 2 snacks immediately or 10 snacks after waiting for 10 min. Two groups were defined based on a median split of waiting time. Four years later, 29 children completed measures of inhibitory control (Flanker task), cognitive flexibility (Dimensional Change Card Sort Test), and working memory (Stanford-Binet Intelligence Scales), and their parents completed the Child Behavior Checklist as a measure of the child's behavioral problems and school functioning. Children with longer wait times on the delay of gratification task in preschool showed better inhibitory control on the Flanker task in middle childhood and better parent-reported school functioning in English. These findings indicate that early inhibitory capacity persists into middle childhood in those with FASD, and may be a promising target for early intervention to improve later cognitive outcomes in these children.

Associations of Five Facets of Mindfulness With Self-Regulation in College Students

Mindfulness has been associated with positive mental health functioning across a range of constructs, including self-regulation. Most of this research, however, has investigated mindfulness as a unidimensional domain. Few studies have examined the relationships between specific facets of mindfulness and particular dimensions of self-regulation, including delay of gratification and emotion regulation, despite relevance for mindfulness-based interventions. Two hundred and seventy-eight undergraduate college student participants completed a series of questionnaires examining dispositional mindfulness, difficulties with emotion regulation, and delay of gratification skills. Linear regressions investigated the associations between five facets of mindfulness and each of the two components of self-regulation. Findings revealed that describing, acting with awareness, nonjudging, and nonreacting mindfulness facets were negatively associated with difficulties with emotion regulation, and that observing, acting with awareness, and nonjudging mindfulness facets were positively associated with delay of gratification skills, after accounting for the effects of the other mindfulness subscales. These preliminary findings may have important clinical relevance, as greater self-regulation has critical implications for social, emotional, and academic functioning.

Same Data Set, Different Conclusions: Preschool Delay of Gratification Predicts Later Behavioral Outcomes in a Preregistered Study

One simple marshmallow test in preschool children predicts an array of important life outcomes, according to multiple studies spanning several decades. However, a recent conceptual replication casts doubt on these famous findings. We conducted an independent, preregistered secondary analysis to test whether previously observed longitudinal associations between preschool delay of gratification and adolescent outcomes would be conceptually replicated. Associations were significant for three of the five outcomes we tested using the analytic approach employed in the original studies of the marshmallow test. Relationships between delay of gratification and problem behavior held in bivariate, multivariate, and multilevel models; in contrast, no significant relationships between delay and problem behavior were found in the other recent replication, even though both studies used the same data set. These relationships were better explained by social support than by self-control, suggesting that the marshmallow test is predictive because it reflects aspects of a child's early environment that are important over the long term. This novel interpretation of the classic findings points to new directions for intervention.

Children Delay Gratification for Cooperative Ends

To cooperate effectively, both in small-scale interactions and large-scale collective-action problems, people frequently have to delay gratification (i.e., resist short-term temptations in favor of joint long-term goals). Although delay-of-gratification skills are commonly considered critical in children's social-cognitive development, they have rarely been studied in the context of cooperative decision-making. In the current study, we therefore presented pairs of children (N = 207 individuals) with a modified version of the famous marshmallow test, in which children's outcomes were interdependently linked such that the children were rewarded only if both members of the pair delayed gratification. Children from two highly diverse cultures (Germany and Kenya) performed substantially better than they did on a standard version of the test, suggesting that children are more willing to delay gratification for cooperative than for individual goals. The results indicate that from early in life, human children are psychologically equipped to respond to social interdependencies in ways that facilitate cooperative success.

The Motivational Aspect of Children's Delayed Gratification: Values and Decision Making in Middle Childhood

Delayed gratification is the ability to postpone an immediate gain in favor of greater and later reward. Although delayed gratification has been studied extensively, little is known about the motivation behind children's decisions. Since values are cognitive representations of individuals' motivations, which serve to guide behavior, we studied the relationship between children's values and delayed gratification. Two main distinct motivations overlapping with values may underlie this decision: conservation - the desire to reduce uncertainty and preserve the status quo, and self-enhancement - the desire to maximize resources and profit for the self. Accordingly, we hypothesized that conservation values would relate to children's preference to hold on to what is given as soon as possible, and that self-enhancement values would relate to children's preference for delaying gratification. Seven-year old children (N = 205) ranked their values with the Picture-Based Values Survey (Döring et al., 2010) as part of the Longitudinal Israeli Study of Twins (LIST) (Avinun and Knafo, 2013). The children also played a decision-making animation game that included delayed gratification decisions. In support of our hypotheses, greater delayed gratification related negatively to conservation values, specifically to security and tradition, and related positively to self-enhancement values, especially power and achievement. This is one of the first demonstrations that children's values relate meaningfully to their behaviors.

Delay of gratification in preschoolers with and without autism spectrum disorder: Individual differences and links to executive function, emotion regulation, and joint attention

This study examined delay of gratification behaviors in preschool-aged children with and without autism spectrum disorder. Recent research has found that elementary-aged children with autism spectrum disorder showed challenges with delay of gratification and that there were individual differences in terms of children's behaviors during the wait. We extend this work to a younger sample of children with autism spectrum disorder to understand whether these difficulties emerge by the preschool years. Moreover, we assessed whether individual differences in other key self-regulatory capacities (i.e. effortful control, emotion regulation, executive function, and joint attention) were related to delay of gratification wait durations or behavioral strategies. Findings revealed that preschoolers with autism spectrum disorder waited for a shorter duration, demonstrated more temptation-focused behaviors, and expressed less positive affect than their typical peers during the delay of gratification task. At the full-sample level, individual differences in children's temptation-focused behaviors (i.e. visual attention and verbalizations focused on the temptation) were related to children's executive function, joint attention, and parents' ratings of emotion regulation. When we examined associations within groups, the associations were not significant for the autism spectrum disorder group, but for typically developing children, there was a positive association between temptation-focused behaviors and emotion regulation.

Parsing profiles of temperamental reactivity and differential routes to delay of gratification: A person-based approach

Informed by a developmental psychopathology perspective, the present study applied a person-based approach to examine whether associations between early sociocontextual experiences (e.g., socioeconomic factors and maternal discipline practices) and preschool-age children's delay of gratification vary across profiles of children's temperamental reactivity. In addition, the study examined the direct and mediating role of children's set shifting in associations with delay of gratification within each profile. The sample consisted of 160 socioeconomically and ethnically diverse mothers and their 5-year-old children drawn from a longitudinal study of mother-child relationships. Latent profile analyses identified three profiles of temperamental reactivity distinguished by sensitivity to reward and punishment and negative affectivity. Multigroup analysis revealed maternal sensitive discipline (observed during a parent-child compliance task) at age 3.5 predicted longer delay of gratification at age 5 in the punishment reactivity/negative affectivity group. Maternal inductive reasoning discipline at age 3.5 predicted longer delay in the low temperamental reactivity group. For children with the reward reactivity/negative affectivity profile, higher family income at age 3.5 predicted longer delay of gratification at age 5, which was mediated by children's set shifting. Findings underscore the utility of person-based approaches for delineating differential developmental routes toward children's delay of gratification.

Indulgent Foods Can Paradoxically Promote Disciplined Dietary Choices

As obesity rates continue to rise, interventions promoting healthful choices will become increasingly important. Here, participants ( N = 79) made binary choices between familiar foods; some trials contained a common consequence that had a constant probability of receipt regardless of the participant's choice. We theorized-on the basis of simulations using a value-normalization model-that indulgent common consequences potentiated disciplined choices by shaping other options' perceived healthfulness and tastiness. Our experimental results confirmed these predictions: An indulgent common consequence more than doubled the rate of disciplined choices. We used eye-gaze data to provide insights into the underlying mechanisms, finding that an indulgent common consequence biased eye gaze toward healthful foods. Furthermore, attention toward the common consequence predicted individual differences in behavioral bias. Results were replicated across two independent samples receiving distinct goal primes. These results demonstrate that introducing an irrelevant indulgent food can alter processing of healthier items-and thus promote disciplined choices.

Better, Not Just More-Contrast in Qualitative Aspects of Reward Facilitates Impulse Control in Pigs

Delay-of-gratification paradigms, such as the famous "Marshmallow Test," are designed to investigate the complex cognitive concepts of self-control and impulse control in humans and animals. Such tests determine whether a subject will demonstrate impulse control by choosing a large, delayed reward over an immediate, but smaller reward. Documented relationships between impulsive behavior and aggression in humans and animals suggest important implications for farm animal husbandry and welfare, especially in terms of inadequate social behavior, tail biting and maternal behavior. In a preliminary study, we investigated whether the extent of impulse control would differ between quantitatively and qualitatively different aspects of reward in pigs. Twenty female piglets were randomly divided into two groups, with 10 piglets each. After a preference test to determine individual reward preference among six different food items, a discrimination test was conducted to train for successful discrimination between different amounts of reward (one piece vs. four pieces) and different qualitative aspects of reward (highly preferred vs. least preferred food item). Then, an increasing delay (2, 4, 8, 16, 24, 32 s) was introduced for the larger/highly preferred reward. Each piglet could choose to get the smaller/least preferred reward immediately or to wait for the larger/highly preferred reward. Piglets showed clear differences in their preference for food items. Moreover, the "quality group" displayed faster learning in the discrimination test (number of sessions until 90% of the animals completed the discrimination test: "quality group"-3 days vs. "quantity group"-5 days) and reached a higher level of impulse control in the delay-of-gratification test compared to the "quantity group" (maximum delay that was mastered: "quality group"-24 s vs. "quantity group"-8 s). These results demonstrate that impulse control is present in piglets but that the opportunity to get a highly preferred reward is more valued than the opportunity to get more of a given reward. This outcome also underlines the crucial role of motivation in cognitive test paradigms. Further investigations will examine whether impulse control is related to traits that are relevant to animal husbandry and welfare.

Posttraumatic Stress, Coping Flexibility, and Risky Drinking Among Trauma-Exposed Male and Female College Students: The Mediating Effect of Delay of Gratification

BACKGROUND

The co-occurence of posttraumatic stress (PTS) and risky drinking has been demonstrated in diverse populations, including college students. However, the mechanisms underlying this co-occurrence, as well as the protective factors that may reduce risky drinking among trauma-exposed college students have yet to be fully understood in the literature.

OBJECTIVES

The present study builds upon self-regulation theories and previous empirical work to determine whether the effects of PTS and coping flexibility on risky drinking were mediated by delay of gratification among trauma-exposed college students. In addition, the potential moderating effect of gender on these relationships was examined.

METHODS

Participants included 624 trauma-exposed college students (68.4% female) attending a public university in the southeast region of the United States. Data were collected through an online survey. The hypothesized model was examined using a multigroup structural equation modeling approach.

RESULTS

As hypothesized, PTS had a significant, positive indirect effect on risky drinking through delay of gratification; however, the effect of PTS on delay of gratification was stronger for males than for females. Results also indicated that the indirect effect of coping flexibility on risky drinking through delay of gratification was significant and negative for males and females. Conclusions/Importance: The findings of this study suggest that delay of gratification might be an important mechanism underlying the co-occurrence of PTS and risky drinking. In addition, our results highlight the potential benefits of coping flexibility for college students coping with PTS.

Self-Control in Chimpanzees Relates to General Intelligence

For humans, there appears to be a clear link between general intelligence and self-control behavior, such as sustained delay of gratification [1-9]. Chimpanzees also delay gratification [10-12] and can be given tests of general intelligence (g) [13-15], but these two constructs have never been compared within the same sample of nonhuman animals. We presented 40 chimpanzees with the hybrid delay task (HDT) [16, 17], which measures inter-temporal choices and the capacity for sustained delay of gratification, and the primate cognitive test battery (PCTB), which measures g in chimpanzees [13-15]. Importantly, none of the sub-tasks in the PCTB directly assesses self-control or other forms of behavioral inhibition. Rather, they assess areas of physical cognition (e.g., quantity discrimination) or social cognition (e.g., gaze following). In three phases of testing, we consistently found that the strongest relation was between chimpanzee g scores and efficiency in the HDT. Chimpanzee g was not most closely related to the proportion of trials the chimpanzees chose to try to wait for delayed rewards, but rather most closely related to how good they were at waiting for those rewards when they chose to do so. We also found the same strong relation between HDT efficiency and those factors in the PCTB that loaded most strongly on chimpanzee g. These results highlight that, as with humans, there is a strong relation between chimpanzees' self-control and overall intelligence-a relation that likely reflects the role of successful inhibitory control during cognitive processing of information and intelligent decision-making.

Delay of Gratification, Delay Discounting and their Associations with Age, Episodic Future Thinking, and Future Time Perspective

The delay of gratification (DoG) in children is widely investigated with an experimental procedure originally called the “marshmallow test,” whereas the studies on self-regulation (SR) in adolescents and adults usually use self-report questionnaires. Delay discounting (DD) measures simplify the DoG procedure and focus on monetary rewards. The aim of this study was to investigate age differences in DoG and DD from childhood to old age using a test that is suitable for both children and adults. Furthermore, investigations were conducted on the association between DoG/DD and two future orientation constructs [future time perspective (FTP) and episodic future thinking (EFT)] as well as age differences in these constructs. Participants from five age groups (9–14, 18–25, 35–55, 65–80, 80+) participated in the study (N = 96). While we found no age difference for DoG, DD was the lowest [i.e., self-control (SC) was the highest] in young/middle adults; however, it was the highest (i.e., SC was the lowest) in children and old/oldest adults. Furthermore, we found significant age differences for DD and FTP. As predicted, there were strong correlations between DoG and FTP and between DD and FTP, but not between DoG/DD and EFT. These results indicate that age differences in SR vary across the measures used. Individuals who generally think and act in a future-oriented manner have a stronger ability to delay gratification.

Relations among Temperament, Self-regulatory Strategies and Gender in Predicting Delay of Gratification

Self-regulation is associated with many positive outcomes, but there is limited information about individual difference regarding children's spontaneous use of strategies to self-regulate and the relative success of those strategies. In the current study, we examined whether temperament and gender are associated with self-regulation and explored the types of spontaneous strategies children use during Mischel's delay of gratification protocol. In addition, we investigated whether spontaneous strategy use during the task could moderate the effects of temperament on self-regulation and whether temperament would mediate the effect of gender on self-regulation. Participants were 349 9-year-olds (182 boys, Mage = 9.18, SD = 1.17). Mothers reported on children's temperament and the Delay of Gratification task was used to assess self-regulation. Both temperament and child's gender were significantly associated with children's delay time. Girls were able to delay longer than boys, and children scoring high on activity level were less able to delay. Activity level also mediated the relationship between gender and delay time. Finally, we found an interaction effect between activity level and certain strategies in relation to self-regulatory behavior.

Search predicts and changes patience in intertemporal choice

People often make decisions with consequences that unfold over time. When facing such intertemporal choices, people use different search strategies. We examine how these search strategies differ and how they relate to patience in intertemporal choice. We demonstrate that search varies substantially across individuals and identify two main search strategies—comparative or integrative search. Importantly, comparative search correlates with greater patience and higher susceptibility to contextual influences on choice. We manipulated search using an unobtrusive technique, revealing a causal relationship between strategy and choice. Comparative searchers make more patient choices and exhibit larger framing effects than integrative searchers. An understanding of how differences in psychological processes change discounting can inform the design of behavioral interventions to improve consumer welfare.

Intertemporal choice impacts many important outcomes, such as decisions about health, education, wealth, and the environment. However, the psychological processes underlying decisions involving outcomes at different points in time remain unclear, limiting opportunities to intervene and improve people’s patience. This research examines information-search strategies used during intertemporal choice and their impact on decisions. In experiment 1, we demonstrate that search strategies vary substantially across individuals. We subsequently identify two distinct search strategies across individuals. Comparative searchers, who compare features across options, discount future options less and are more susceptible to acceleration versus delay framing than integrative searchers, who integrate the features of an option. Experiment 2 manipulates search using an unobtrusive method to establish a causal relationship between strategy and choice, randomly assigning participants to conditions promoting either comparative or integrative search. Again, comparative search promotes greater patience than integrative search. Additionally, when participants adopt a comparative search strategy, they also exhibit greater effects of acceleration versus delay framing. Although most participants reported that the manipulation did not change their behavior, promoting comparative search decreased discounting of future rewards substantially and speeded patient choices. These findings highlight the central role that heterogeneity in psychological processes plays in shaping intertemporal choice. Importantly, these results indicate that theories that ignore variability in search strategies may be inadvertently aggregating over different subpopulations that use very different processes. The findings also inform interventions in choice architecture to increase patience and improve consumer welfare.

More Is Meaningful: The Magnitude Effect in Intertemporal Choice Depends on Self-Control

Impulsivity is a variable behavioral trait that depends on numerous factors. For example, increasing the absolute magnitude of available choice options promotes farsighted decisions. We argue that this magnitude effect arises in part from differential exertion of self-control as the perceived importance of the choice increases. First, we demonstrated that frontal executive-control areas were more engaged for more difficult decisions and that this effect was enhanced for high-magnitude rewards. Second, we showed that increased hunger, which is associated with lower self-control, reduced the magnitude effect. Third, we tested an intervention designed to increase self-control and showed that it reduced the magnitude effect. Taken together, our findings challenge existing theories about the magnitude effect and suggest that visceral and cognitive factors affecting choice may do so by influencing self-control.

Toward a laboratory model for psychotherapeutic treatment screening: Implementation intentions and incentives for abstinence in an analog of smoking relapse

Despite reductions in cigarette smoking in the United States, approximately 40 million Americans are smokers. Innovative interventions are needed to help remaining smokers quit. To develop innovative interventions, precise and effective tools are needed. Here, a laboratory model of smoking relapse is assessed for its ability to detect increased resistance to smoking across 2 interventions and for its sensitivity to differing degrees of effectiveness. Nicotine-deprived participants (N = 36) completed, in randomized order, 4 smoking resistance sessions with and without implementation intentions and monetary incentives. A Cox proportional hazard mixed-effects model indicated significant differences between condition, χ²(3) = 64.87, p < .001, and the Questionnaire on Smoking Urges, χ²(1) = 4.86, p = .03. Comparisons between conditions were used to estimate the effect size of each condition on delay to smoking reinitiation. The implementation intentions intervention had a small effect (d = 0.32), the monetary incentives had a large effect (d = 0.89) and the combination of both interventions had a large effect size (d = 1.20). This initial investigation of the smoking resistance paradigm showed sensitivity to smoking reinitiation across intervention conditions. Individuals resisted smoking significantly more in the presence of monetary incentives and implementation intentions than without these interventions. These results provide support for further examination of these interventions in more translational settings and the use of this laboratory analog to screen future interventions and treatment packages.

Delay of gratification in middle childhood: Extending the utility and sensitivity of the standard task

The ability to delay gratification is an important aspect of the development of self-regulation and executive functioning. Standard tasks to assess delay of gratification are typically only useful up to age 5 years. A modified task was developed and administered to a sample of 126 (59 males and 67 females) typically developing Australian children aged 5-12 years. Results showed that 7-year-olds were significantly more likely to delay than 5-year-olds. A ceiling effect was observed from age 7 onwards. Performance on the modified task correlated significantly with other executive functioning tasks, demonstrating the convergent validity of the task. This study was successful in extending the usefulness of the standard delay of gratification task to age 7. Suggestions for further development of this task are discussed.

A new approach to measuring patience in preschoolers

Patience in children has usually been studied using delay of gratification paradigms. However, another important aspect of patience that has not been well documented is the ability to adjust one's behavior while waiting without an explicit reward as a motivator (e.g., sitting in the doctor's waiting room). To examine this aspect of patience, video-recordings of sixty-one 3- and 4-year olds waiting for two separate 3-min periods were examined and coded for children's spontaneous behaviors. We found that 4-year olds displayed more patient (i.e., staying still) behaviors than 3-year olds during this "waiting paradigm." Interestingly, we also found that children who displayed less patient behaviors during the waiting paradigm were also those who succeeded on a future-thinking task. These findings have important implications for measuring patience in young children and highlight the potential impact of spontaneous behaviors on children's performance in cognitive tasks such as those assessing future-oriented cognition.

Measures of Dogs' Inhibitory Control Abilities Do Not Correlate across Tasks

Inhibitory control, the ability to overcome prepotent but ineffective behaviors, has been studied extensively across species, revealing the involvement of this ability in many different aspects of life. While various different paradigms have been created in order to measure inhibitory control, only a limited number of studies have investigated whether such measurements indeed evaluate the same underlying mechanism, especially in non-human animals. In humans, inhibitory control is a complex construct composed of distinct behavioral processes rather than of a single unified measure. In the current study, we aimed to investigate the validity of inhibitory control paradigms in dogs. Sixty-seven dogs were tested in a battery consisting of frequently used inhibitory control tests. Additionally, dog owners were asked to complete an impulsivity questionnaire about their dog. No correlation of dogs' performance across tasks was found. In order to understand whether there are some underlying behavioral aspects explaining dogs' performance across tests, we performed principle component analyses. Results revealed that three components (persistency, compulsivity and decision speed) explained the variation across tasks. The questionnaire and dogs' individual characteristics (i.e., age and sex) provided only limited information for the derived components. Overall, results suggest that no unique measurement for inhibitory control exists in dogs, but tests rather measure different aspects of this ability. Considering the context-specificity of inhibitory control in dogs and most probably also in other non-human animals, extreme caution is needed when making conclusions about inhibitory control abilities based on a single test.

α2A -Adrenergic receptor polymorphisms and mRNA expression levels are associated with delay discounting in cocaine users

Cocaine users characteristically display preferences for smaller immediate rewards over larger delayed rewards, and this delay discounting (DD) has been proposed as an endophenotype of cocaine addiction. Recent evidence suggests that the norepinephrine system and more specifically the α_2A -adrenergic receptor (ADRA2A) are impacted by chronic cocaine use while also being potentially involved in the neural mechanisms underlying DD. Hence, we investigated the effects of ADRA2A polymorphisms and ADRA2A mRNA expression levels on DD of cocaine users and stimulant-naïve controls. Two hundred and twenty-three participants (129 cocaine users and 94 stimulant-naïve healthy controls) completed a computerized DD paradigm and were genotyped for three single nucleotide polymorphisms (SNPs; rs1800544, rs521674 and rs602618) in the ADRA2A gene, while their peripheral ADRA2A mRNA expression was quantified in whole blood samples. The three SNPs were in near-perfect linkage disequilibrium. Accordingly, significant group*genotype interactions were found for all three ADRA2A variants revealing steeper DD in cocaine users (but not in controls) carrying the G-allele of SNP rs1800544, the T-allele of rs521674 and the C-allele of rs602618. Similarly, high ADRA2A mRNA expression levels were significantly associated with a reduced tendency to choose smaller more immediate rewards (over larger delayed rewards) in cocaine users but not in controls. As the relationship between DD and cocaine use was moderated by ADRA2A SNPs and by peripheral ADRA2A gene expression, we propose that the norepinephrine system is involved in DD deficits observed in cocaine using individuals. Consequently, pharmacological compounds targeting ADRA2As might be considered for the symptom-specific treatment of delay aversion in stimulant addiction.

Chimpanzees can point to smaller amounts of food to accumulate larger amounts but they still fail the reverse-reward contingency task

The reverse-reward contingency task presents 2 food sets to an animal, and they are required to choose the smaller of the 2 sets in order to receive the larger food set. Intriguingly, the majority of species tested on the reverse-reward task fail to learn this contingency in the absence of large trial counts, correction trials, and punishment techniques. The unique difficulty of this seemingly simple task likely reflects a failure of inhibitory control which is required to point toward a smaller and less desirable reward rather than a larger and more desirable reward. This failure by chimpanzees and other primates to pass the reverse-reward task is striking given the self-control they exhibit in a variety of other paradigms. For example, chimpanzees have consistently demonstrated a high capacity for delay of gratification in order to maximize accumulating food rewards in which foods are added item-by-item to a growing set until the subject consumes the rewards. To study the mechanisms underlying success in the accumulation task and failure in the reverse-reward task, we presented chimpanzees with several combinations of these 2 tasks to determine when chimpanzees might succeed in pointing to smaller food sets over larger food sets and how the nature of the task might determine the animals' success or failure. Across experiments, 3 chimpanzees repeatedly failed to solve the reverse-reward task, whereas they accumulated nearly all food items across all instances of the accumulation self-control task, even when they had to point to small amounts of food to accumulate larger amounts. These data indicate that constraints of these 2 related but still different tasks of behavioral inhibition are dependent upon the animals' perceptions of the choice set, their sense of control over the contents of choice sets, and the nature of the task constraints.

Effect of the Children's Health Activity Motor Program on Motor Skills and Self-Regulation in Head Start Preschoolers: An Efficacy Trial

Self-regulatory skills are broadly defined as the ability to manage emotions, focus attention, and inhibit some behaviors while activating others in accordance with social expectations and are an established indicator of academic success. Growing evidence links motor skills and physical activity to self-regulation. This study examined the efficacy of a motor skills intervention (i.e., the Children's Health Activity Motor Program, CHAMP) that is theoretically grounded in Achievement Goal Theory on motor skill performance and self-regulation in Head Start preschoolers. A sample of 113 Head Start preschoolers (Mage = 51.91 ± 6.5 months; 49.5% males) were randomly assigned to a treatment (n = 68) or control (n = 45) program. CHAMP participants engaged in 15, 40-min sessions of a mastery climate intervention that focused on the development of motor skills over 5 weeks while control participants engaged in their normal outdoor recess period. The Delay of Gratification Snack Task was used to measure self-regulation and the Test of Gross Motor Development-2nd Edition was used to assess motor skills. All measures were assessed prior to and following the intervention. Linear mixed models were fit for both self-regulation and motor skills. Results revealed a significant time × treatment interaction (p < 0.001). In regard to motor skills, post hoc comparisons found that all children improved their motor skills (p < 0.05), but the CHAMP group improved significantly more than the control group (p < 0.001). Children in CHAMP maintained their self-regulation scores across time, while children in the control group scored significantly lower than the CHAMP group at the posttest (p < 0.05). CHAMP is a mastery climate movement program that enhance skills associated with healthy development in children (i.e., motor skills and self-regulation). This efficacy trial provided evidence that CHAMP helped maintain delay of gratification in preschool age children and significantly improved motor skills while participating in outdoor recess was not effective. CHAMP could help contribute to children's learning-related skills and physical development and subsequently to their academic success.

Delay of gratification: a comparison study of children with Down syndrome, moderate intellectual disability and typical development

BACKGROUND

Self-regulation has been found to be an important contributor to a range of outcomes, with delay of gratification (a self-regulatory skill) predicting better academic, social and personal functioning. There is some evidence that individuals with Down syndrome have difficulty with delay of gratification. We investigated the question of whether this difficulty is common to intellectual disability irrespective of aetiology, or whether it presents a particular problem for those with Down syndrome. The latter was considered a possibility because of language difficulties in this group.

METHOD

Three groups of children with a mean MA between 36 and 60 months participated in the study: children with Down syndrome (n = 32), children with a moderate intellectual disability from a cause other than Down syndrome (n = 26) and typically developing children (n = 50). Children completed a series of measures of language and cognitive functioning and participated in a delay of gratification task.

RESULTS

The group of children with Down syndrome delayed for a significantly shorter time than either of the other two groups that did not differ from each other. Receptive language was associated with delay time for the children with Down syndrome but not for the typically developing group, nor for the group with moderate intellectual disability.

CONCLUSIONS

Children with Down syndrome appear to have a particular difficulty with delay of gratification. Language abilities would seem to be implicated in this difficulty, although further examination of this hypothesis is required.

Vagal Tone and Children's Delay of Gratification: Differential Sensitivity in Resource-Poor and Resource-Rich Environments

Children from different socioeconomic backgrounds have differing abilities to delay gratification, and impoverished children have the greatest difficulties in doing so. In the present study, we examined the role of vagal tone in predicting the ability to delay gratification in both resource-rich and resource-poor environments. We derived hypotheses from evolutionary models of children's conditional adaptation to proximal rearing contexts. In Study 1, we tested whether elevated vagal tone was associated with shorter delay of gratification in impoverished children. In Study 2, we compared the relative role of vagal tone across two groups of children, one that had experienced greater impoverishment and one that was relatively middle-class. Results indicated that in resource-rich environments, higher vagal tone was associated with longer delay of gratification. In contrast, high vagal tone in children living in resource-poor environments was associated with reduced delay of gratification. We interpret the results with an eye to evolutionary-developmental models of the function of children's stress-response system and adaptive behavior across varying contexts of economic risk.

Enabling Delay of Gratification Behavior in Those Not So Predisposed: The Moderating Role of Social Support

The presence of delay of gratification (DG) in childhood is correlated with success later in a person's life. Is there any way of helping adults with a low level of DG to obtain similar success? The present research examines how social support helps those low in DG nonetheless to act similarly to those high in DG. This research includes both correlational studies and experiments that manipulate social support as well as both field studies and a laboratory study. The results show that with high social support, employees (Study 1) and university students (Study 2) low in DG report vocational and academic DG behavioral intentions, respectively, similar to those high in DG. Study 3 found that participants low in DG who were primed with high social support expressed job-choice DG similar to those high in the DG. Study 4 controlled for mood and self-image and found that participants low in DG who were primed with high social support expressed more money-choice DG than those high in the DG. Study 5 showed that social support moderated the relationship between DG and actual DG behaviors. These findings provide evidence for a moderating role of social support in the expression of DG behavior.

Delay of gratification is associated with white matter connectivity in the dorsal prefrontal cortex: a diffusion tensor imaging study in chimpanzees (Pan troglodytes)

Individual variability in delay of gratification (DG) is associated with a number of important outcomes in both non-human and human primates. Using diffusion tensor imaging (DTI), this study describes the relationship between probabilistic estimates of white matter tracts projecting from the caudate to the prefrontal cortex (PFC) and DG abilities in a sample of 49 captive chimpanzees (Pan troglodytes). After accounting for time between collection of DTI scans and DG measurement, age and sex, higher white matter connectivity between the caudate and right dorsal PFC was found to be significantly associated with the acquisition (i.e. training phase) but not the maintenance of DG abilities. No other associations were found to be significant. The integrity of white matter connectivity between regions of the striatum and the PFC appear to be associated with inhibitory control in chimpanzees, with perturbations on this circuit potentially leading to a variety of maladaptive outcomes. Additionally, results have potential translational implications for understanding the pathophysiology of a number of psychiatric and clinical outcomes in humans.
