Early-Life Stressors, Personality Development, and Fast Life Strategies: An Evolutionary Perspective on Malevolent Personality Features

The impact of parenting style on malevolent creativity based on Chinese university students: a latent profile analysis

Introduction

This study investigated the association between parenting styles and malevolent creativity.

Methods

It used latent profile analysis to compare the differences in malevolent creativity between different combinations of parenting styles with an online sample (N = 620).

Results

The results of the study suggest that a three-profile solution best fits the data, and the three profiles were labelled positive open parenting, undifferentiated parenting and negative limited parenting. Subsequent analyses revealed that there were significant differences in malevolent creativity performance among the three parenting styles, with participants in the positive open parenting having more malevolent creativity. Those with undifferentiated parenting had the lowest scores.

Discussion

The findings provide theoretical guidance for parenting strategies. Future intervention studies on malevolent creativity should also consider the potential impact of parenting style to obtain better results.

Examining relationships between adverse childhood experiences and coping during the cost-of-living crisis using a national cross-sectional survey in Wales, UK

OBJECTIVES

Adverse childhood experiences (ACEs) can affect individuals' resilience to stressors and their vulnerability to mental, physical and social harms. This study explored associations between ACEs, financial coping during the cost-of-living crisis and perceived impacts on health and well-being.

DESIGN

National cross-sectional face-to-face survey. Recruitment used a random quota sample of households stratified by health region and deprivation quintile.

SETTING

Households in Wales, UK.

PARTICIPANTS

1880 Welsh residents aged ≥18 years.

MEASURES

Outcome variables were perceived inability to cope financially during the cost-of-living crisis; rising costs of living causing substantial distress and anxiety; and self-reported negative impact of rising costs of living on mental health, physical health, family relationships, local levels of antisocial behaviour and violence, and community support. Nine ACEs were measured retrospectively. Socioeconomic and demographic variables included low household income, economic inactivity, residential deprivation and activity limitation.

RESULTS

The prevalence of all outcomes increased strongly with ACE count. Perceived inability to cope financially during the cost-of-living crisis increased from 14.0% with 0 ACEs to 51.5% with 4+ ACEs. Relationships with ACEs remained after controlling for socioeconomic and demographic factors. Those with 4+ ACEs (vs 0 ACEs) were over three times more likely to perceive they would be unable to cope financially and, correspondingly, almost three times more likely to report substantial distress and anxiety and over three times more likely to report negative impacts on mental health, physical health and family relationships.

CONCLUSIONS

Socioeconomically deprived populations are recognised to be disproportionately impacted by rising costs of living. Our study identifies a history of ACEs as an additional vulnerability that can affect all socioeconomic groups. Definitions of vulnerability during crises and communications with services on who is most likely to be impacted should consider childhood adversity and history of trauma.

Childhood adversity and accelerated reproductive events: a systematic review and meta-analysis

OBJECTIVE

Accelerated female reproductive events represent the early onset of reproductive events involving puberty, menarche, pregnancy loss, first sexual intercourse, first birth, parity, and menopause. This study aimed to explore the association between childhood adversity and accelerated female reproductive events.

DATA SOURCES

PubMed, Web of Science, and Embase were systematically searched from September 22, 2022 to September 23, 2022.

STUDY ELIGIBILITY CRITERIA

Observational cohort, cross-sectional, and case-control studies in human populations were included if they reported the time of reproductive events for female individuals with experience of childhood adversity and were published in English.

METHODS

Two reviewers independently screened studies, obtained data, and assessed study quality, and conflicts were resolved by a third reviewer. Dichotomous outcomes were evaluated using meta-analysis, and pooled odds ratios and 95% confidence intervals were generated using random-effects models. Moderation analysis and meta-regression were used to investigate heterogeneity.

RESULTS

In total, 21 cohort studies, 9 cross-sectional studies, and 3 case-control studies were identified. Overall, female individuals with childhood adversity were nearly 2 times more likely to report accelerated reproductive events than those with no adversity exposure (odds ratio, 1.91; 95% confidence interval, 1.33-2.76; I2=99.6%; P<.001). Moderation analysis indicated that effect sizes for the types of childhood adversity ranged from an odds ratio of 1.61 (95% confidence interval, 1.23-2.09) for low socioeconomic status to 2.13 (95% confidence interval, 1.14-3.99) for dysfunctional family dynamics. Among the 7 groups based on different reproductive events, including early onset of puberty, early menarche, early sexual initiation, teenage childbirth, preterm birth, pregnancy loss, and early menopause, early sexual initiation had a nonsignificant correlation with childhood adversity (odds ratio, 2.70; 95% confidence interval, 0.88-8.30; I2=99.9%; P<.001). Considerable heterogeneity (I2>75%) between estimates was observed for over half of the outcomes. Age, study type, and method of data collection could explain 35.9% of the variance.

CONCLUSION

The literature tentatively corroborates that female individuals who reported adverse events in childhood are more likely to experience accelerated reproductive events. This association is especially strong for exposure to abuse and dysfunctional family dynamics. However, the heterogeneity among studies was high, requiring caution in interpreting the findings and highlighting the need for further evaluation of the types and timing of childhood events that influence accelerated female reproductive events.

Intergenerational cascade processes from parental childhood adversity to child emotional and behavioral problems

BACKGROUND

Parental adverse childhood experiences (ACEs) may transmit to the next generation and influence children's emotional and behavioral problems. Relatively little evidence exists on the underlying pathways of this intergenerational transmission at the family- and individual-level.

OBJECTIVE

This study examined the intergenerational cascade processes of parental ACEs on children's emotional and behavioral problems via family cohesion, children's ACEs, and children's self-control.

PARTICIPANTS AND SETTING

283 children (52 % male, Mage = 10.47 years) and their parents (61.1 % mothers, Mage = 38.62 years) were recruited for a 2-month longitudinal study with surveys administered at three time points.

METHOD

Mediation models examined the intergenerational effects of parental ACEs (T1/T3) and family cohesion (T1) as reported by parents, and children's ACEs (T1) and children's self-control (T2) as reported by children, on children's internalizing and externalizing problems (T3) as reported by parents.

RESULTS

Family cohesion, children's ACEs, and children's self-control sequentially mediated the link between parental ACEs and children's externalizing problems (indirect effect = 0.004, 95 % CI [0.001, 0.014]). Parental ACEs were directly linked with children's internalizing problems (β = 0.191, SE = 0.075, p = .011).

CONCLUSIONS

Findings demonstrated intergenerational cascades of distal and proximal risk processes from parental ACEs to children's behavioral problems. These findings have implications for future interventions on children's externalizing problems that aim at improving family cohesion and children's self-control for families exposed to childhood adversity.

The Effect of Parenting Practices on Creativity: Mediating Role of Psychological Resilience

Aim

This study aimed to investigate the relationship between parenting practices and creativity (both general and malignant creativity) in a representative sample of college students in China, and to explore the potential mediating role of resilience.

Methods

The study was conducted among 1201 Chinese college students who completed questionnaires on parenting practices, creativity, and resilience. The parenting practices were assessed using the short-form Egna Minnen av Barndoms Uppfostran for Chinese, while creativity was measured using the Malevolent Creativity Behavior Scale and the Runco Ideational Behavior Scale. The Connor-Davidson Resilience Scale was used to assess resilience.

Results

The results showed that parental warmth had a positive correlation with general creativity, but a negative correlation with malevolent creativity. In contrast, parental rejection and over-protection had a negative correlation with general creativity, but a positive correlation with malevolent creativity. Furthermore, resilience fully mediated the relationship between emotional warmth, rejection, and general creativity, and partially mediated the relationship between over-protection and general creativity and between all parenting practices and malevolent creativity.

Conclusion

These findings suggest that parenting practices have a significant impact on creativity, and the type of creativity manifested may depend on the specific parenting practices. Additionally, the study highlights the importance of resilience as a potential mediator in the relationship between parenting practices and creativity. The implications of these findings for parenting practices and interventions to foster creativity and resilience are discussed.

Correlation Analyses Between Childhood Behavioral Disturbance and Maternal Alexithymia: An Observational Study

Purpose

Caregivers' responses have an impact on children's emotional and behavioral development. The inability of caregivers to perceive their own emotions affects their responses to children. This study aims to examine the relationship between a mother's difficulties in emotional expression and children's emotional and behavioral disorders.

Patient and Methods

A total of 78 cases, aged between 3 and 15 years old, were included in this study. The mothers completed the Taiwan version of the "Toronto Alexithymia Scale" (TAS) and "Children's Behavior Checklist" (CBCL) questionnaires, which served as research tools. TAS consists of three factors: difficulty in distinguishing emotions (Factor 1, F1), difficulty in expressing feelings (Factor 2, F2), and an externally oriented thinking style (Factor 3, F3). CBCL represents a child's behavior profile. The Mann-Whitney test and correlation analyses were used for follow-up analysis.

Results

Our analysis revealed that F1, F2, F3, and total scores of TAS (TAS-Total) correlate positively with the somatic complaint subscale of CBCL (F1: p = 0.003; F2: p = 0.002; F3: p = 0.034, TAS-Total p=0.002). Additionally, TAS-F1 was positively correlated with the internalizing problems subscale of CBCL (p = 0.020) and the withdrawn (WD) subscale of CBCL (p = 0.044). We also found a significant association between TAS-F1 and WD of CBCL in boys alone (p = 0.022). However, we observed a negative association between TAS-F3 and the social problems subscale of CBCL in boys alone (p = 0.038).

Conclusion

Mothers with alexithymic features are more likely to have children who internalize emotions, leading to withdrawal and somatic expression. Boys tend to exhibit withdrawal traits associated with internalization. This study provides initial evidence of a partial correlation between maternal alexithymia and children's emotional and behavioral disorders, emphasizing the importance of investigating caregivers' emotional traits for a better understanding of children's development in the future.

Association between early life adversity and allostatic load in girls with precocious puberty

CONTEXT

The mechanisms underlying the elevated long-term health risk in girls with precocious puberty remain unclear, but might result from physiological wear and tear associated with greater exposure to early life adversity.

OBJECTIVE

This study aims to explore early life adversity in girls with precocious puberty and its association with allostatic load.

METHODS

Early life adversity and hair cortisol concentration were measured among 213 girls with precocious puberty (8.21 ± 1.07). Allostatic load score is constructed by using 13 physiological biomarkers representing four systems and hair cortisol concentration. Multivariate linear regression models have estimated the associations between cumulative early life adversity exposure with total and system-specific allostatic load scores. Associations between cumulative early life adversity and the risk of high allostatic load (3 + high-risk biomarkers) were tested using binary logistics regression.

RESULTS

More than two-thirds (67.6%) of girls with central precocious puberty reported two or more early life adversity exposure. Compared to those with no early life adversity exposure, girls who reported early life adversity score ≥ 2 had significantly higher total allostatic load score (β: 1.20-1.64, P < 0.001). Metabolic system was more sensitive to cumulative early life adversity exposure, each form of early life adversity exposure was associated with 0.48-unit increases in metabolic allostatic load score (95%CI: 0.06, 0.90, P = 0.026). Girls reported early life adversity score ≥ 3 were three times more likely to have a high allostatic load compared with those without early life adversity exposure in both unadjusted and adjusted models (OR_adjusted=3.83, 95%CI: 1.17, 12.55, P = 0.001).

CONCLUSION

Multisystem physiological dysregulation is observed in girls with central precocious puberty, which might result from cumulative wear-and-tear associated with early life adversity.

The Origins of the Dark—Hyperactivity and Negative Peer Relationships, an Objectively Lower Sleep Efficiency, and a Longer Sleep Onset Latency at Age Five Were Associated with Callous-Unemotional Traits and Low Empathy at Age 14

Background: Within the spectrum of emotional competencies, callous-unemotional traits are socially discouraged, while empathy is considered a socially much more accepted emotional trait. This holds particularly true for adolescents, who are still building up their social and emotional competencies. The aims of the present study were two-fold: First, longitudinally, to identify traits of behavioral problems and objective sleep dimensions at the age of 5 years to predict callous-unemotional traits and empathy at the age of 14 years. Second, cross-sectionally, to associate callous-unemotional traits and empathy with current insomnia, stress, and mental toughness. Methods: Preschoolers at the age of 5 years were contacted nine years later at the age of 14 years. At 5 years, parents rated their children’s behavior (Strength and Difficulties Questionnaire, SDQ); in parallel, children underwent a one-night sleep-EEG assessment. At the age of 14 years, adolescents completed a series of questionnaires covering callous-unemotional traits, insomnia, empathy, stress, and mental toughness. Results: A total of 77 adolescents (38.1% females) took part in the present study. Longitudinally, higher scores for hyperactivity at age 5 significantly predicted higher callous-unemotional traits at age 14. A higher score for negative peer relationships at age 5 significantly predicted lower scores for cognitive empathy at age 14. Further, objective sleep-EEG measures showed that a higher sleep efficiency and a shorter sleep latency was associated with lower scores for callousness. Cross-sectionally, higher scores for callous-unemotional traits were associated with higher insomnia and stress, while lower insomnia was associated with higher empathy. Mental toughness was unrelated to callous-unemotional traits and empathy. Conclusions: It appears that hyperactivity traits and negative peer relationships and more unfavorable objective sleep patterns at 5 years predicted socially discouraged callous-unemotional traits and low empathy during adolescence. Further, cross-sectionally at the age of 14, callous-unemotional traits, subjective poor sleep, and higher stress were associated.

The evolution of personality disorders: A review of proposals

Personality disorders (PDs) are currently considered dysfunctions. However, personality differences are older than humanity and are ubiquitous in nature, from insects to higher primates. This suggests that a number of evolutionary mechanisms-other than dysfunctions-may be able to maintain stable behavioral variation in the gene pool. First of all, apparently maladaptive traits may actually improve fitness by enabling better survival or successful mating or reproduction, as exemplified by neuroticism, psychopathy, and narcissism. Furthermore, some PDs may harm important biological goals while facilitating others, or may be globally beneficial or detrimental depending on environmental circumstances or body condition. Alternatively, certain traits may form part of life history strategies: Coordinated suites of morphological, physiological and behavioral characters that optimize fitness through alternative routes and respond to selection as a whole. Still others may be vestigial adaptations that are no longer beneficial in present times. Finally, variation may be adaptative in and by itself, as it reduces competition for finite resources. These and other evolutionary mechanisms are reviewed and illustrated through human and non-human examples. Evolutionary theory is the best-substantiated explanatory framework across the life sciences, and may shed light on the question of why harmful personalities exist at all.

The relationship between childhood adversity and problem behavior of new street corner youth on campus: A moderate mediation model

To explore the impact mechanism of childhood adversity on problem behaviors of new street corner youth on campus, we surveyed 637 new street corner youth on campus and completed the Strengths and Difficulties Questionnaire, the Childhood Environment Scale, the Life History Strategies Scale, and the Dark Triad Scale. After controlling for gender and age of new street corner youth on campus, results revealed that childhood adversity was significantly and positively associated with problem behaviors. Mediation analysis showed that life history strategy mediated the association between childhood adversity and problem behaviors. Moreover, moderated mediation analysis further indicated that dark triad moderated the association between childhood adversity and life history strategy, as well as the association between life history strategy and problem behaviors. These findings suggest that interventions of life history strategy and dark triad may be effective means to affect problem behaviors of new street corner youth on campus.

Flexible societies excelled in saving lives in the first phase of the COVID-19 pandemic

Background

Previous studies have shown that national cultural traits, such as collectivism–individualism and tightness–looseness, are associated with COVID-19 infection and mortality rates. However, although East Asian countries have outperformed other countries in containing COVID-19 infections and lowering mortality in the first pandemic waves, no studies to date have examined flexibility-monumentalism, a cultural trait that uniquely distinguishes East Asia from the rest of the world. Moreover, none of the previous studies have explored mechanisms underpinning the association between national culture and COVID-19 mortality.

Aims

Our study fills in these gaps by examining the association between flexibility-monumentalism and COVID-19 mortality, adjusting for important covariates and by analyzing mask wearing and fear of COVID-19 during the first weeks of the pandemic as plausible mechanisms underpinning this association.

Methods

We constructed and analyzed a dataset including 37 countries that have valid information on flexibility-monumentalism, COVID-19 deaths as of 31 October 2020 (before the start of vaccination campaigns), and relevant covariates including two other national cultural traits (individualism–collectivism and tightness–looseness) and other national characteristics (economic, political, demographic and health). Multiple linear regression with heteroscedasticity-consistent standard errors was used to assess the independent effect of flexibility-monumentalism on COVID-19 mortality. Mediation was assessed by examining the indirect effects of flexibility through mask wearing and fear of COVID-19 and determining the statistical significance through bootstrapping. Graphical and delete-one analysis was used to assess the robustness of the results.

Results

We found that flexibility was associated with a significant reduction in COVID-19 mortality as of 31 October 2020, independent of level of democracy, per capita GDP, urbanization, population density, supply of hospital beds, and median age of the population. This association with mortality is stronger and more robust than for two other prominent national cultural traits (individualism–collectivism and tightness–looseness). We also found tentative evidence that the effect of flexibility on COVID-19 mortality may be partially mediated through mask wearing in the first weeks of the pandemic.

A Double-Track Pathway to Fast Strategy in Humans and Its Personality Correlates

The fast-slow paradigm of life history (LH) focuses on how individuals grow, mate, and reproduce at different paces. This paradigm can contribute substantially to the field of personality and individual differences provided that it is more strictly based on evolutionary biology than it has been so far. Our study tested the existence of a fast-slow continuum underlying indicators of reproductive effort-offspring output, age at first reproduction, number and stability of sexual partners-in 1,043 outpatients with healthy to severely disordered personalities. Two axes emerged reflecting a double-track pathway to fast strategy, based on restricted and unrestricted sociosexual strategies. When rotated, the fast-slow and sociosexuality axes turned out to be independent. Contrary to expectations, neither somatic effort-investment in status, material resources, social capital, and maintenance/survival-was aligned with reproductive effort, nor a clear tradeoff between current and future reproduction was evident. Finally, we examined the association of LH axes with seven high-order personality pathology traits: negative emotionality, impulsivity, antagonism, persistence-compulsivity, subordination, and psychoticism. Persistent and disinhibited subjects appeared as fast-restricted and fast-unrestricted strategists, respectively, whereas asocial subjects were slow strategists. Associations of LH traits with each other and with personality are far more complex than usually assumed in evolutionary psychology.

The phenotype of recovery VI: The association between life-history strategies, delay discounting, and maladaptive health and financial behaviors among individuals in recovery from alcohol use disorders

BACKGROUND

The life-history theory is a well-established framework that predicts behaviors and explains how and why organisms allocate effort and resources to different life goals. Delay discounting (DD) is associated with risky behaviors and has been suggested as a candidate behavioral marker of addiction. Thus, we investigated the relationship between DD, life-history strategies, and engagement in risky behaviors among individuals in recovery from alcohol use disorder (AUD).

METHODS

Data from 110 individuals in recovery from addiction from The International Quit & Recovery Registry, an ongoing online registry designed to understand recovery phenotype, were included in the analysis. The association between life-history strategies, DD, engagement in risky behaviors, and remission status were assessed.

RESULTS

Life-history strategy scores were significantly associated with DD rates and finance, health, and personal development behaviors after controlling for age, sex, race, ethnicity, years of education, marital status, smoking status, and history of other substance use. Remission status was significantly associated with life-history strategy, DD, drug use, fitness, health, and safe driving after controlling for age, sex, race, years of education, marital status, and smoking status. In addition, a mediation analysis using Hayes' methods revealed that the discounting rates partially mediated the association between remission status and life-history strategy scores.

CONCLUSIONS

Life-history strategies and remission status are both significantly associated with DD and various health and finance behaviors among individuals in recovery from AUD. This finding supports the characterizations of DD as a candidate behavioral marker of addiction that could help differentiate subgroups needing special attention or specific interventions to improve the outcomes of their recovery. Future longitudinal studies are warranted to understand the relationships between changes in life-history strategies, DD, maladaptive health behaviors, and remission status over time.

Associations between distinct dimensions of early life adversity and accelerated reproductive strategy among middle-aged women in China

BACKGROUND

Life history theory argues that unpredictable and harsh conditions such as early life adversity tends to produce a fast life history strategy, characterized by early sexual maturation and less parenting of offspring. It remains unclear whether all forms of early life adversity are associated with accelerated reproductive strategy, and most previous studies predominantly focused on single form of reproductive strategy indicators.

OBJECTIVE

To examine the associations between 2 distinct dimensions of early life adversity (ie, threat and deprivation) and reproductive strategies across global metrics.

STUDY DESIGN

We used data from 9674 middle-aged women of the China Health and Retirement Longitudinal Study. The experiences of threat and deprivation were assessed using the Life History Survey Questionnaire in 2014. Reproductive strategy information was assessed via self-report from the follow-up of 2013, 2015 and 2018, including age at menarche, age at natural menopause, age at first birth, total number of children, and number of abortions. Multivariate linear regression analyses were performed to assess the associations between distinct dimensions of early life adversity and multiple reproductive strategy indicators, adjusting for age, Hukou location, family socioeconomic status in adulthood and body mass index.

RESULTS

Of the 9674 women (mean [standard deviation] age at baseline, 55.89 [10.23] years), 4084 (42.20%) reported exposure to threat-related early life adversity and 7332 (75.79%) reported exposure to deprivation-related early life adversity. Early life adversity characterized by threat was associated with accelerated reproductive strategy. Compared with women who have no experiences of threat-related early life adversity, ≥3 threat-related early life adversity was associated with 3.7-month earlier age at menarche (β=-0.31, 95% confidence interval, -0.53 to -0.08; P=.007), 8.6-month earlier age at natural menopause (β=-0.72, 95% confidence interval, -1.29 to -0.15; P=.013), >1-year earlier age at first birth (β=-1.14, 95% confidence interval, -1.58 to -0.71; P<.0001), and an increased total number of children (β=0.25, 95% confidence interval, 0.10-0.41; P=.002). In contrast, experiences of deprivation were associated with delayed age at natural menopause (β=.50, 95% confidence interval, 0.06-0.94; P=.025) and increased number of abortions (β=.17, 95% confidence interval, 0.01-0.34, P=.037), in models adjusting for co-occurring threat exposures.

CONCLUSION

This study suggests that early life adversity characterized by threat was associated with accelerated reproductive strategy, whereas deprivation was associated with slower reproduction strategy. Future research should clarify the biological pathways between different dimensions of early life adversity and reproductive strategies and further determine whether accelerated reproduction is an adaptive response to early life adversity in humans.

Chaos May Prevail Without Filial Piety: A Cross-Cultural Study on Filial Piety, the Dark Triad, and Moral Disengagement

In traditional Chinese society, filial piety (FP) served as the philosophical foundation of social governance, without which chaos would prevail. It indicates that the function of FP is not limited to family. FP can predict attitudes and behaviors in other social contexts. This study examined the relationship between FP and moral disengagement, and the mediating roles of the dark triad personality, and cultural differences regarding these mechanisms. An online self-report survey was conducted in two different culture groups- university students from China (N = 400, 37% male, Mage = 20.41, SD age = 2.52) and Islamic countries who are studying in China (N = 378, 59.25% male, Mage = 24.29, SD age = 4.77). Correlation analysis showed that authoritarian FP was positively associated with moral disengagement among students from China and Islamic countries, while reciprocal FP only negatively correlated with moral disengagement among Chinese students. Moreover, reciprocal FP directly and negatively affected moral disengagement, and did so indirectly through the mediating role of Machiavellianism. However, authoritarian FP directly and positively influenced moral disengagement, and did so indirectly through the buffering role of narcissism. These two parallel mediating models are not affected by culture. Though FP varies from culture to culture, reciprocal FP and authoritarian FP play critical roles in influencing personality and moral development. Reciprocal FP reduces moral disengagement directly and indirectly by weakening Machiavellianism. The role of authoritarian FP is conflicting. It can strengthen moral disengagement, but may also weaken it by deterring the development of the narcissistic personality. The findings enlighten us to view authoritarian FP dialectically. These two parallel mediating models are not affected by culture, indicating the applicability of DFPM in other societies. Future studies are encouraged to involve participants from more divergent countries and cultural backgrounds.

Relatedness Need Satisfaction and the Dark Triad: The Role of Depression and Prevention Focus

Dark triad traits are often associated with maladaptive social and interpersonal interactions, such as dishonesty and self-centeredness; thus, it is important to explore predictors of the dark triad in order to better facilitate the reduction of such behaviors. The present study adopted a self-report approach with a total of 5,207 Chinese undergraduate students participated in the study. We found that relatedness need dissatisfaction significantly predicted the presence of dark personalities, which was mediated by prevention focus. Conditional process model analysis found that this mediating effect was stronger when depression levels were lower. Final study results contributed to further understanding predictors of the dark triad. Study limitations and future research directions were also examined.

Unhealthy parenting strategies: Situational (Dis-)Incentives, Machiavellian personality, and their interaction on misuse of ADHD medication for healthy children

Some parents engage in the potentially unhealthy and morally debateable parenting practice of giving prescription stimulant drugs to healthy children to boost their school and extracurricular performance. However, the parents' underlying reasoning remains unexamined. This web-based study (N_Respondents = 1360) simultaneously investigates eight experimentally-varied situational (dis-)incentives (e.g., financial gains and drug properties) within a factorial vignette survey (N_Vignettes = 256), Machiavellianism as a measured socially relevant personality trait, and possible interaction effects. Results show that approximately 40% of the described situations (N_Evaluations = 5440) provoked some willingness to medicate healthy children. Multilevel mixed-effect models revealed that this willingness was higher, for example, with increasing financial gains and weaker side effects. Machiavellians disclosed a higher willingness. They were more responsive to financial gains and threats (e.g., probable side effects). Respondents' sex, age, ethnicity, and experience with prescription drugs also had effects. Prevention measures might emphasize the dangers and limited potential of prescription drugs for healthy children.

The Relationship Between Childhood Neglect and Malevolent Creativity: The Mediating Effect of the Dark Triad Personality

In addition to what we know as benevolent creativity, which involves originality and usefulness, creativity also includes malevolent creativity, which involves the application of creative ideas to intentionally harm others. This study aimed to explore the environmental and individual predictors of malevolent creativity. We investigated the relationship among childhood neglect, Dark Triad personality traits and malevolent creativity and examined the mediating role of Dark Triad personality. A large sample (N = 991) of Chinese undergraduate students completed the childhood neglect scale, the 12-item Dirty Dozen and the Malevolent Creativity Behavior Scale. Structural equation modeling demonstrated that childhood neglect was positively related to individual malevolent creativity, and the Dark Triad partially mediated this relationship. Additionally, gender differences were found, such that childhood neglect had a stronger effect on malevolent creativity through the Dark Triad among males than females. The results were discussed from the perspectives of life history theory and social information processing theory.

Effect of Dark Personalities on Knowledge Hiding Behaviour at Higher Education Institutions

A key concern in the way of improving knowledge sharing practices is knowledge hiding behaviour. Literature shows that knowledge hiding is a prevalent phenomenon in organisations including higher education institutions (HEIs) and is largely determined by the personality of the knowledge holders. Thus, the present study attempts to examine the effect of dark personalities (undesirable personality traits comprising of Machiavellianism, narcissism, and psychopathy) on knowledge hiding behaviour of faculty members at HEIs. Based on 139 valid responses from the full-time faculty members serving in various private universities in Bangladesh, the study revealed that both Machiavellianism and psychopathy have significant positive association with knowledge hiding behaviour of the academics, whereas narcissism is insignificantly related with knowledge hiding behaviour. This study indicated that dark personalities play a key role in academics’ inclination to hide knowledge.

Human Capital and Administrative Burden: The Role of Cognitive Resources in Citizen-State Interactions

One means by which the state reinforces inequality is by imposing administrative burdens that loom larger for citizens with lower levels of human capital. Integrating insights from various disciplines, this article focuses on one aspect of human capital: cognitive resources. The authors outline a model that explains how burdens and cognitive resources, especially executive functioning, interrelate. The article then presents illustrative examples, highlighting three common life factors-scarcity, health problems, and age-related cognitive decline. These factors create a human capital catch-22, increasing people's likelihood of needing state assistance while simultaneously undermining the cognitive resources required to negotiate the burdens they encounter while seeking such assistance. The result is to reduce access to state benefits and increase inequality. The article concludes by calling for scholars of behavioral public administration and public administration more generally to incorporate more attention to human capital into their research.

A Life History Approach to the Female Sexual Orientation Spectrum: Evolution, Development, Causal Mechanisms, and Health

Women's capacity for sexual fluidity is at least as interesting a phenomenon from the point of view of evolutionary biology and behavioral endocrinology as exclusively homosexual orientation. Evolutionary hypotheses for female nonheterosexuality have failed to fully account for the existence of these different categories of nonheterosexual women, while also overlooking broader data on the causal mechanisms, physiology, ontogeny, and phylogeny of female nonheterosexuality. We review the evolutionary-developmental origins of various phenotypes in the female sexual orientation spectrum using the synergistic approach of Tinbergen's four questions. We also present femme-specific and butch-specific hypotheses at proximate and ultimate levels of analysis. This review article indicates that various nonheterosexual female phenotypes emerge from and contribute to hormonally mediated fast life history strategies. Life history theory provides a biobehavioral explanatory framework for nonheterosexual women's masculinized body morphology, psychological dispositions, and their elevated likelihood of experiencing violence, substance use, obesity, teenage pregnancy, and lower general health. This pattern of life outcomes can create a feedback loop of environmental unpredictability and harshness which destabilizes intrauterine hormonal conditions in mothers, leading to a greater likelihood of fast life history strategies, global health problems, and nonheterosexual preferences in female offspring. We further explore the potential of female nonheterosexuality to function as an alloparental buffer that enables masculinizing alleles to execute their characteristic fast life history strategies as they appear in the female and the male phenotype. Synthesizing life history theory with the female sexual orientation spectrum enriches existing scientific knowledge on the evolutionary-developmental mechanisms of human sex differences.

The Mediating Role of the Dark Triad Between Life History Strategy and Perceived Stress Factors

Life History Theory posits early-life adversities affect personality development partway through sensitizing individuals to certain environmental cues, thus influencing the person’s responses to different stressors. We therefore hypothesized that life history strategy affects perceived distress and self-efficiency in coping through certain personality traits. The concept of the Dark Triad describes specific forms of personalities found to be associated with faster life strategies and perceived stress. Hence, the aim of our study was to examine the possible mediator role of the Dark Triad traits on the relationship between life strategies and perceived stress. A sample of 432 (133 males) under- and postgraduate students (aged between 18 and 34 years, M= 23.4, SD = 3.9) answered the Short-Form of the Arizona Life History Battery, the Mini-K, the Perceived Stress Scale, and the Short Dark Triad. Multiple linear regression and subsequent mediation analyses showed significant mediation effects of Dark Triad traits on both perceived distress and perceived coping. Our results indicate that these personality traits are part of the process in which faster life strategies predict higher level of perceived stress and lower levels of coping ability.

Reflections on self-determination theory as an organizing framework for personality psychology: Interfaces, integrations, issues, and unfinished business

OBJECTIVE

This special issue focuses on self-determination theory (SDT) as an integrative framework for the wider field of personality research. In this commentary our aims include: reflecting on the utility and strengths of SDT as such a general framework and responding to the various contributions in this issue regarding their use of SDT as a guiding, complementary, or contrasting framework.

METHODS AND RESULTS

We describe how SDT has developed organically and conservatively from "within" based on the emerging patterns of evidence, as well through the ongoing challenges from other models and frameworks. We then discuss each of the various contributions to this special issue, addressing themes that include SDT's breadth of methods, and its relevance to topics such as narcissism, wisdom, individual differences, Big-Five traits, and the neuropsychology of motivation, among others. Across these discussions, we highlight fruitful avenues for research and cross-fertilization across the fields of personality, development, motivation, and neuroscience. At the same time, we counter some claims made about SDT, and forward certain cautions regarding the integration of SDT and other personality frameworks and models.

CONCLUSIONS

We conclude by revisiting the value of broad theory, and SDT in particular, for coordinating complex research findings concerning motivation, personality development and wellness across multiple levels of analysis and, perhaps more importantly, for pointing researchers to the right questions within today's prolific empiricism.
