Context-dependent approach and avoidance behavioral profiles as predictors of psychopathology

Inhibition (a temperamental profile characterized by elevated levels of avoidance behaviors) is associated with increased likelihood for developing anxiety and depression, whereas exuberance (a temperamental profile characterized by elevated levels of approach behaviors) is associated with increased likelihood for developing externalizing conditions (e.g., attention deficit/hyperactivity disorder and conduct disorder). However, not all children who exhibit high levels of approach or avoidance behaviors develop emotional or behavioral problems. In this preregistered study, we assessed context-dependent profiles of approach and avoidance behaviors in 3-year-old children (N = 366). Using latent profile analysis, four groups were identified: nonsocial approachers, social approachers, social avoiders, and nonsocial avoiders. Analyses revealed that there were minimal differences in internalizing and externalizing symptoms across the four context-dependent groups. However, exploratory analyses assessed whether high levels of approach or avoidance combined across contexts, similar to findings reported in prior work, were related to psychopathology. Children identified as high in avoidance behavior at 3 years of age were more likely to show internalizing symptoms at 3 years of age but not at 5 years of age. Children high in approach were more likely to meet criteria for anxiety and externalizing disorders by age 5 years. These findings further our understanding of individual differences in how young children adjust their behavior based on contextual cues and may inform methods for identifying children at increased likelihood for the development of emotional and behavioral problems. RESEARCH HIGHLIGHTS: Context-dependent approach and avoidance profiles were identified in 3-year-old children using a person-centered approach. Children who were high in approach behavior, regardless of context, at age three had a higher likelihood for developing an anxiety or externalizing disorder by age five. These findings may help identify children at increased risk of developing emotional and behavioral problems.

Love on the developing brain: Maternal sensitivity and infants' neural responses to emotion in the dorsolateral prefrontal cortex

Infancy is a sensitive period of development, during which experiences of parental care are particularly important for shaping the developing brain. In a longitudinal study of N = 95 mothers and infants, we examined links between caregiving behavior (maternal sensitivity observed during a mother-infant free-play) and infants' neural response to emotion (happy, angry, and fearful faces) at 5 and 7 months of age. Neural activity was assessed using functional Near-Infrared Spectroscopy (fNIRS) in the dorsolateral prefrontal cortex (dlPFC), a region involved in cognitive control and emotion regulation. Maternal sensitivity was positively correlated with infants' neural responses to happy faces in the bilateral dlPFC and was associated with relative increases in such responses from 5 to 7 months. Multilevel analyses revealed caregiving-related individual differences in infants' neural responses to happy compared to fearful faces in the bilateral dlPFC, as well as other brain regions. We suggest that variability in dlPFC responses to emotion in the developing brain may be one correlate of early experiences of caregiving, with implications for social-emotional functioning and self-regulation.

Taking a lifespan approach to polygenic scores

This commentary is a call to action for researchers to create and use genome-wide association studies (GWASs) with previously missed age groups (e.g., infancy, elderly), which will improve our ability to ask important developmental questions using genetic data to trace pathways across the lifespan.

Infant and maternal responses to emotional facial expressions: A longitudinal study

The current longitudinal study (N = 107) examined mothers' facial emotion recognition using reaction time and their infants' affect-based attention at 5, 7, and 14 months of age using eyetracking. Our results, examining maternal and infant responses to angry, fearful and happy facial expressions, show that only maternal responses to angry facial expressions were robustly and positively linked across time points, indexing a consistent trait-like response to social threat among mothers. However, neither maternal responses to happy or fearful facial expressions nor infant responses to all three facial emotions show such consistency, pointing to the changeable nature of facial emotion processing, especially among infants. In general, infants' attention toward negative emotions (i.e., angry and fear) at earlier timepoints was linked to their affect-biased attention for these emotions at 14 months but showed greater dynamic change across time. Moreover, our results provide limited evidence for developmental continuity in processing negative emotions and for the bidirectional interplay of infant affect-biased attention and maternal facial emotion recognition. This pattern of findings suggests that infants' affect-biased attention to facial expressions of emotion are characterized by dynamic changes.

Beyond accidents: Young children's forgiveness of third-party intentional transgressors

To maintain our cooperative relationships, it is critical that we repair these relationships when they are damaged by transgressions. Key to this repair is forgiveness. Previous research suggests that adults and children are more forgiving of remorseful transgressors than of unremorseful ones after accidental transgressions. However, little is known about whether children's forgiveness also takes the transgressors' intentions into account. Using a third-person video paradigm with children in the United States, Study 1 found that 6-year-olds (n = 20; 10 girls; 60% White) were more likely to negatively evaluate an intentional transgressor and give more resources to an accidental transgressor when both transgressors showed remorse, whereas 5-year-olds (n = 20; 10 girls; 80% White) showed this effect only in their resource distribution. Study 2 found that 6-year-olds (n = 18; 7 girls; 83% White) were more likely to positively evaluate and share more resources with a remorseful intentional transgressor than with an unremorseful intentional one. Thus, by school age in the United States, children's forgiveness, at least as bystanders, begins to take into account both the transgressor's intentions and the display of remorse.

Frontal asymmetry assessed in infancy using functional near-infrared spectroscopy is associated with emotional and behavioral problems in early childhood

Frontal asymmetry (FA), the difference in brain activity between the left versus right frontal areas, is thought to reflect approach versus avoidance motivation. This study (2012-2021) used functional near-infrared spectroscopy to investigate if infant (Mage  = 7.63 months; N = 90; n = 48 male; n = 75 White) FA in the dorsolateral prefrontal cortex relates to psychopathology in later childhood (Mage  = 62.05 months). Greater right FA to happy faces was associated with increased internalizing (η2  = .09) and externalizing (η2  = .06) problems at age 5 years. Greater right FA to both happy and fearful faces was associated with an increased likelihood of a lifetime anxiety diagnosis (R2  > .13). FA may be an informative and early-emerging marker for psychopathology.

Maternal recognition of positive emotion predicts sensitive parenting in infancy

Research on parent-child relationships demonstrates the importance of maternal sensitivity for the development of children's emotion regulation, social competence, and health; thus, it is important to understand the emotional-cognitive capacities underlying maternal sensitivity. We followed 120 mothers and their full-term infants from the newborn period to 5 months postpartum. Mothers' emotion recognition during the newborn period was measured using a validated facial emotion recognition task assessing discrimination (d') of six facial expressions of emotion: happiness, fear, anger, sadness, disgust, and neutrality. Maternal behavior at 5 months postpartum was coded from a mother-infant free-play session using Ainsworth's Sensitivity Scales. Preregistered analyses revealed that mothers' ability to detect happiness specifically (but not other emotions such as fear or sadness) in the neonatal period predicted greater observed sensitivity 4 months later, β = .30, p = .002, ΔR² = .08. Results suggest that maternal recognition of positive emotion may be uniquely predictive of sensitive behavior in low-stress parent-infant interaction contexts.

Examining the Role of Socioeconomic Status and Maternal Sensitivity in Predicting Functional Brain Network Connectivity in 5-Month-Old Infants

Infancy is a sensitive period of human brain development that is plastically shaped by environmental factors. Both proximal factors, such as sensitive parenting, and distal factors, such as socioeconomic status (SES), are known predictors of individual differences in structural and functional brain systems across the lifespan, yet it is unclear how these familial and contextual factors work together to shape functional brain development during infancy, particularly during the first months of life. In the current study, we examined pre-registered hypotheses regarding the interplay between these factors to assess how maternal sensitivity, within the broader context of socioeconomic variation, relates to the development of functional connectivity in long-range cortical brain networks. Specifically, we measured resting-state functional connectivity in three cortical brain networks (fronto-parietal network, default mode network, homologous-interhemispheric connectivity) using functional near-infrared spectroscopy (fNIRS), and examined the associations between maternal sensitivity, SES, and functional connectivity in a sample of 5-month-old infants and their mothers (N = 50 dyads). Results showed that all three networks were detectable during a passive viewing task, and that maternal sensitivity was positively associated with functional connectivity in the default mode network, such that infants with more sensitive mothers exhibited enhanced functional connectivity in this network. Contrary to hypotheses, we did not observe any associations of SES with functional connectivity in the brain networks assessed in this study. This suggests that at 5 months of age, maternal sensitivity is an important proximal environmental factor associated with individual differences in functional connectivity in a long-range cortical brain network implicated in a host of emotional and social-cognitive brain processes.

Variability in Infants' Functional Brain Network Connectivity Is Associated With Differences in Affect and Behavior

Variability in functional brain network connectivity has been linked to individual differences in cognitive, affective, and behavioral traits in adults. However, little is known about the developmental origins of such brain-behavior correlations. The current study examined functional brain network connectivity and its link to behavioral temperament in typically developing newborn and 1-month-old infants (M [age] = 25 days; N = 75) using functional near-infrared spectroscopy (fNIRS). Specifically, we measured long-range connectivity between cortical regions approximating fronto-parietal, default mode, and homologous-interhemispheric networks. Our results show that connectivity in these functional brain networks varies across infants and maps onto individual differences in behavioral temperament. Specifically, connectivity in the fronto-parietal network was positively associated with regulation and orienting behaviors, whereas connectivity in the default mode network showed the opposite effect on these behaviors. Our analysis also revealed a significant positive association between the homologous-interhemispheric network and infants' negative affect. The current results suggest that variability in long-range intra-hemispheric and cross-hemispheric functional connectivity between frontal, parietal, and temporal cortex is associated with individual differences in affect and behavior. These findings shed new light on the brain origins of individual differences in early-emerging behavioral traits and thus represent a viable novel approach for investigating developmental trajectories in typical and atypical neurodevelopment.

Probing infants' sensitivity to pupil size when viewing eyes

Sensitive responding to eye cues plays a key role in human social interactions. Pupil size provides subtle cues regarding a social interaction partner's arousal states. The current study assessed infants' sensitivity to and preference for differences in pupil size. Specifically, we examined White 14-month-old infants' pupillary responses when viewing own-race and other-race (Asian) eyes with dilating, constricting, and static medium-sized pupils. Our results show that, independent of race, infants' pupils dilated more when viewing eyes with dynamically changing (dilating and constricting) pupils than when viewing eyes with non-changing, static, and medium-sized pupils. We also measured infants' looking preferences, showing that, independent of race, infants preferentially attended to eyes with dilated pupils. Moreover, our results show that infants orient more quickly to pupillary changes in own-race eyes than in other-race eyes. These findings demonstrate that infants detect, but do not mimic, changes in pupil size in others and show a preference for eyes with dilated pupils.

Community-based service requests and utilization among pregnant women incarcerated in jail

Pregnant incarcerated women represent a unique population in the criminal justice system that has been largely overlooked in terms of their service-related needs. The present study examines 241 pregnant incarcerated women's service requests and preincarceration service utilization related to material help (e.g., food, housing), mental health (e.g., counseling), family services (e.g., home-visiting nurses), and health care (e.g., insurance). A subsample (n = 74) also provided information about service utilization following their release from jail. Analyses examined request and utilization patterns in relation to other sociodemographic risk experiences. Results show that specific risk factors such as age, as well as the accumulation of multiple risk factors, served as barriers to requesting and accessing community-based services. The present study illuminates unique challenges pregnant incarcerated women experience requesting and utilizing services. The results support the use of a gender-responsive, trauma-informed approach to better address the needs of these women. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
