Longitudinal Changes in Psychosocial Adjustment Before and During the COVID-19 Pandemic for Adolescents with Differential Patterns of Solitude and Sociability.

Previous research has lacked a comprehensive, longitudinal analysis of characteristics of solitude and sociability, and how they are associated with changes in psychosocial adjustment before and during the pandemic. The current study surveyed 1071 adolescents (Mage = 10.6, SD = 1.69, 49.86% female, age range = 8-14 years at Year 1) over six years (three years before pandemic, three years during pandemic). Piecewise linear mixed-effects analysis showed that adolescents with higher solitude and lower sociability reported improvements in adjustment during the pandemic, whereas adolescents with lower solitude and higher sociability reported declines in adjustment. The findings highlight the importance of considering multiple characteristics of solitude and sociability, as well as contextual factors (e.g., pandemic), to better understand the implications of solitude on adolescent adjustment.

Children's shyness and early stages of emotional face processing.

The ability to detect and recognize facial emotions emerges in childhood and is important for understanding social cues, but we know relatively little about how individual differences in temperament may influence early emotional face processing. We used a sample of 419 children (Mage = 10.57 years, SD = 1.75; 48% female; 77% White) to examine the relation between temperamental shyness and early stages of emotional face processing (assessed using the P100 and N170 event-related potentials) during different facial expressions (neutral, anger, fear, and happy). We found that higher temperamental shyness was related to greater P100 activation to faces expressing anger and fear relative to neutral faces. Further, lower temperamental shyness was related to greater N170 activation to faces expressing anger and fear relative to neutral faces. There were no relations between temperamental shyness and neural activation to happy faces relative to neutral faces for P100 or N170, suggesting specificity to faces signaling threat. We discuss findings in the context of understanding the early processing of facial emotional display of threat among shy children.

Exploring EEG resting state as a function of boredom proneness in pre-adolescents and adolescents.

Boredom is a prominent experience commonly reported in school settings and associated with poor academic achievement. Little is known, however, about the age-related trajectory of boredom. Here we examined self-reported ratings of boredom in a cross-sectional sample of 8 to 15-year olds (n = 185) as a function of resting state EEG. Results indicated that reports of boredom in school rose as a function of age. Resting state EEG showed a decrease in theta power with age perhaps reflective of increased control. While no effects were evident in beta and alpha bands, we did observe an interaction between boredom and age for frontal asymmetry such that for those higher in boredom, the asymmetry increased with age. Finally, for theta to beta ratios there were main effects of age (i.e., a decrease in theta/beta ratio with age) and boredom such that those higher in boredom had higher theta/beta ratios over frontal and central brain areas. The results are discussed in the context of prior work on school-related boredom and provide several important avenues for further research.

Longitudinal associations between lie evaluations and frequency: The moderating role of age.

While previous studies have demonstrated correlations between children and adolescents' evaluations of lies and lie-telling behaviors, the temporal order of these associations over time and changes across this developmental period remain unexamined. The current study examined longitudinal associations among children and adolescents' (N = 1128; Mage = 11.54, SD = 1.68, 49.80% male, and 83.6% white) evaluations of lies to parents for autonomy and lie-telling frequency to parents and friends. Autoregressive cross-lagged analysis revealed longitudinal associations moderated by age. Among children, evaluations of lies predicted greater lie-telling rates over time. Conversely, among adolescents, lie-telling frequency predicted lie evaluations over time, and evaluations predicted lying to parents over time. These results demonstrate a novel developmental pattern of the associations between moral evaluations of lies and lie-telling. RESEARCH HIGHLIGHTS: Children and adolescents' evaluations of lie-telling and lie-telling frequency were associated longitudinally, but the direction of this association was moderated by age. Among children, more positive lie evaluations predicted greater lie-telling to parents and friends over time. Among adolescents, more positive lie evaluations predicted lying more often to parents over time; lying more to parents and friends predicted more positive evaluations over time. These findings suggest a novel developmental pattern regarding the temporal order of the association between evaluations of lie-telling and lie-telling frequency.

When is Solitude Maladaptive for Adolescents? A Comprehensive Study of Sociability and Characteristics of Solitude.

Research examining the link between solitude and psychosocial adjustment among adolescents has lacked a comprehensive, person-centered examination of differential patterns of both solitude and sociability. The current study surveyed 1071 adolescents (Mage = 12.48, SD = 1.71, 49.86% female, age range = 10-16 years). Using latent-profile analysis, four groups were identified with differential patterns of characteristics of solitude (i.e., enjoyment, motivations, preference, frequency) and sociability. Results indicated that worse psychosocial adjustment across time points was associated with membership in the PFS-NonSociable group (characterized by high enjoyment, preference, and frequency of solitude; low sociability) compared to all other groups. Findings suggest that solitude for adolescents appears to be linked to worse psychosocial adjustment only if accompanied by a lack of sociability.

A Latent Profile Analysis of Lie-Telling to Parents and Friends during Adolescence.

Adolescence has been suggested to be a time of heightened lie-telling. The current study used a latent profile analysis to examine unique patterns of lie-telling for lies told to parents and friends during adolescence as well as whether adjustment indicators (relationship quality, depressive symptoms, social anxiety, externalizing problems) could be used to predict group membership. These patterns were examined among 828 10- to 16- year-olds (Mage = 12.39, SD = 1.69, 49.9% male). In both relationships, 5-profile solutions emerged; most adolescents reported very infrequent lie-telling, while a small portion (less than 5%) told high rates of lies. Adjustment indicators predicted group membership. Depressive symptoms, social anxiety, parent relationship quality, and externalizing problems predicted group membership for lying to parents. Depressive symptoms and social anxiety predicted group membership for lying to friends. The findings indicate that high rates of lie-telling found in previous research may be driven by a small number of prolific lie-tellers.

Developmental trajectories of sensitivity to threat in children and adolescents predict larger medial frontal theta differentiation during response inhibition.

Sensitivity to threat (ST) is thought to be a hallmark of the onset and maintenance of anxiety, which often manifests behaviorally as withdrawal, increased arousal and hypervigilant monitoring of performance. The current study investigated whether longitudinal trajectories of ST were linked to medial frontal (MF) theta power dynamics, a robust marker of performance monitoring. Youth (N = 432, Mage = 11.96 years) completed self-report measures of threat sensitivity annually for 3 years. A latent class growth curve analysis was used to identify distinct profiles of threat sensitivity over time. Participants also completed a GO/NOGO task while electroencephalography was recorded. We identified three threat sensitivity profiles: (i) high (n = 83), (ii) moderate (n = 273) and (iii) low ( n= 76). Participants in the high threat sensitivity class had greater levels of MF theta power differentiation (NOGO-GO) compared to participants in the low threat sensitivity class, indicating that consistently high threat sensitivity is associated with neural indicators of performance monitoring. Of concern, both hypervigilant performance monitoring and threat sensitivity have been associated with anxiety; thus, youth with high threat sensitivity may be at risk for the development of anxiety.

Longitudinal associations between impulsivity and lie-telling in childhood and adolescence.

Lie-telling and impulsivity levels peak during late childhood to early adolescence and have been suggested to be related. Heightened impulsivity may lead adolescents to lie in favor of short-term benefits without consideration for the potential consequences of deception. The present study assessed longitudinal relations between self-reported impulsivity and lie-telling frequency. Participants from a large-scale longitudinal study (N = 1148; Mage  = 11.55, SD = 1.69, 9-15 years at Time 1) reported on their impulsivity (Barratt Impulsiveness Scale) and their frequency of lie-telling to parents, to teachers, to friends, and about cheating across two time points 1 year apart. Cross-lagged path analysis revealed greater impulsivity was associated with more frequent lie-telling to parents, friends, and teachers, and about cheating over time. Our findings demonstrate the role of impulsivity in the development of lie-telling behaviors. RESEARCH HIGHLIGHTS: Impulsivity predicts lying across time in multiple contexts (to parents, friends, teachers, and about cheating). Previous research has demonstrated the role of top-down influences on lie-telling, but the current study suggests that bottom-up processes are also influential.

Deliberate Self-injury in Children and Associations With Negative Adjustment.

This study examines patterns between known childhood and adolescence self-injury behavior and longitudinal patterns with negative adjustment.

Frontal EEG alpha-delta ratio and social anxiety across early adolescence.

Although the mean age of onset of social anxiety disorder (SAD) is during adolescence, we know relatively little about the neurodevelopmental correlates of subsyndromal social anxiety in early adolescence before SAD manifests. Here we examined frontal EEG alpha/delta ratio (a putative proxy of brain maturation) in relation social anxiety symptoms across early adolescence. Resting regional EEG spectral power measures were collected continuously for 4 min (2 min eyes-open, 2 min eyes-closed) in slow (i.e., delta) and fast (i.e., alpha) frequencies at Time 1, and self-reported social anxiety measures were collected concurrently at Time 1 and then prospectively approximately one year later (Time 2) in 103 typically developing 12- to 14-year-olds (46.6% female, Mage = 12.91 years, SDage = 0.81 years). Using a latent class growth curve analysis, stable high and stable low social anxiety classes were derived from the two assessments. Controlling for children's age, sex, and pubertal development, we found that youth in the stable high social anxiety class were more likely to exhibit a relatively lower frontal alpha/delta ratio, reflecting ostensibly less brain maturation relative to youth in the stable low social anxiety class. Results were specific to social anxiety and did not extend to symptoms of generalized anxiety. Findings are discussed in terms of the putative functions of less brain maturation in understanding individual differences in complex human social behavior.

Affinity for Solitude and Motivations for Spending Time Alone Among Early and Mid- Adolescents.

Research on the link between affinity for solitude (a tendency to enjoy time alone) and psychosocial adjustment among adolescents has been mixed; however, this may depend on whether time spent alone is motivated by positive (self-reflection, creative pursuits) or reactive (negative affect, avoiding social interaction) factors. The current study investigated affinity for solitude and motivations for spending time alone among 1072 early to mid-adolescents (Mage = 12.48 years, age range = 10-16, 49.8% female). Higher reactive solitude predicted depressive symptoms, peer victimization, and lower self-esteem, controlling for previous scores on these adjustment indicators. For social anxiety and friendship quality, there were significant 3-way interactions between affinity for solitude, reactive solitude, and frequency of time spent alone, indicating that the relation between affinity for solitude and these latter adjustment indicators depends on why and how often youth spend time alone. Findings indicate that attention should be given to youth who spend time alone for reactive reasons, as this appears to be associated with negative adjustment.

A developmental examination of medial frontal theta dynamics and inhibitory control.

Medial frontal theta-band oscillations are a robust marker of action-outcome monitoring. In a large developmental sample (n = 432, 9-16 years), we examined whether phase and non-phase locked medial frontal theta power were related to inhibitory control among children and adolescents. Our results showed that the well-established increase in medial frontal theta power during inhibitory control was captured largely by non-phase locked dynamics, which partially mediated the positive effect of age on task performance. A person-centered approach also revealed latent classes of individuals based on their multivariate theta power dynamics (phase locked/non-phase locked, GO/NOGO). The class of individuals showing low phase locked and high non-phase locked medial frontal theta were significantly older, had better inhibitory control, scored higher on measures of general cognitive function, and were more efficient in their behavioural responses. The functional significance of phase and non-phase locked theta dynamics, and their potential changes, could have important implications for action-outcome monitoring and cognitive function in both typical and atypical development, as well as related psychopathology .

An ERP investigation of children and adolescents' sensitivity to wins and losses during a peer observation manipulation.

The purpose of this ERP P3 study was to test a peer observation manipulation (being observed by a peer versus being alone) on neural markers of attention to reward (win-feedback) and punishment (loss-feedback) during the Balloon Analogue Risk Task. Participants (126 children, 53 % male, 8-10 years; 196 early adolescents, 50 % male, 11-13 years; and 121 mid-adolescents, 52 % male, 14-16 years) were assessed by age group and pubertal status. Individual differences in how participants felt about being observed by a peer, and self-report personality factors, also were examined. Findings indicated that early and mid-adolescents (and individuals in mid-puberty and late-puberty) were sensitive to peer observation as both groups showed larger neural responses to loss-feedback in the peer condition than in the alone condition. Conversely, children (and individuals in pre- and early-puberty) were unaffected by peer observation. In addition, there clearly were individual differences in how rewarding versus anxiety-provoking participants found the peer experience. Early adolescents and mid-adolescents (and individuals in mid- and late-puberty) who reported feeling more anxious about the peer observation elicited larger neural responses to loss-feedback, and individuals in mid- and late-puberty in particular reported higher worry and lower sensation-seeking scores than those who reported a positive experience.

Shyness and prosocial tendencies during adolescence: Prospective influence of two types of self-regulation.

Although children's self-regulation has been widely regarded as a panacea, there may be individual differences in the adaptiveness of self-regulatory processes depending on temperamental factors. We examined whether individual differences in two conceptually distinct types of self-regulation (i.e., emotion self-regulation, nonemotion self-regulation) moderated the association between shyness measured during late childhood (N = 1284; 49.8% girls, 84.1% White, mean parental education fell between associate's degree/diploma and undergraduate degree) and prosocial tendencies indexed approximately two years later during early adolescence. We found that children's shyness was negatively associated with adolescents' prosocial tendencies only at high levels of emotion self-regulation, and that shyness was positively related to prosocial tendencies only at low levels of nonemotion self-regulation. In the context of relatively higher levels of shyness, being "over" emotionally regulated may interfere with positive socioemotional outcomes. These findings may provide additional insight into the heterogeneity of self-regulation, and why some shy children may be reluctant to engage in prosocial acts.

Approach-avoidance conflict and shyness: A developmental investigation.

One long-standing theoretical model of shyness proposes that the origins and maintenance of shyness are associated with an approach-avoidance motivational conflict (Asendorpf, 1990), such that shy individuals are motivated to socially engage (high approach motivation) but are too anxious to do so (high avoidance motivation). However, this model has not been empirically tested in predicting the development of shyness. In two separate longitudinal studies, we used the Carver and White (1994) Behavioral Inhibition and Activation System (BIS/BAS) scales as a proxy of approach-avoidance motivations and growth curve analyses to examine whether individual differences in these hypothesized motivational tendencies were associated with the development of shyness across 3 years from late childhood to adolescence (Study 1, N = 1284; 49.8% female, Mage = 10.72, SDage = 1.73, M level of parental education fell between associate's degree/diploma and undergraduate degree) and across nearly a decade from emerging adulthood to young adulthood (Study 2, N = 83; 57.8% females, Mage = 23.56 years, SDage = 1.09 years, 92.8% had at least a high school education). Contrary to the approach-avoidance conflict model of shyness, we found that a combination of high BIS/low BAS, not high BIS/high BAS, was associated with relatively higher shyness contemporaneously and across development in both studies. We discuss the processes that might link individual differences in approach-avoidance motivations to the development of shyness in adolescence and young adulthood.

Cortical maturation from childhood to adolescence is reflected in resting state EEG signal complexity.

Endogenous cortical fluctuations captured by electroencephalograms (EEGs) reflect activity in large-scale brain networks that exhibit dynamic patterns over multiple time scales. Developmental changes in the coordination and integration of brain function leads to greater complexity in population level neural dynamics. In this study we examined multiscale entropy, a measure of signal complexity, in resting-state EEGs in a large (N = 405) cross-sectional sample of children and adolescents (9-16 years). Our findings showed consistent age-dependent increases in EEG complexity that are distributed across multiple temporal scales and spatial regions. Developmental changes were most robust as the age gap between groups increased, particularly between late childhood and adolescence, and were most prominent over fronto-central scalp regions. These results suggest that the transition from late childhood to adolescence is characterized by age-dependent changes in the underlying complexity of endogenous brain networks.

Development of shyness across adolescence: Reactivity, regulation, or both?

The reactivity-regulation model suggests that the origins and maintenance of shyness results from relatively high levels of reactivity in combination with relatively low levels of regulation. Although this model has received some empirical support, there are still issues regarding directionality of the relations among variables and a dearth of studies examining the joint influence of reactivity and regulation on the prospective development of shyness. Using a longitudinal design, we first examined whether the relations among reactivity, regulation, and shyness were unidirectional or bidirectional in a sample of 1284 children (49.8% female, 84.1% White; mean parental education fell between associate degree/diploma and undergraduate degree) assessed annually across three waves from late childhood and early adolescence (Mage = 10.72 years) to adolescence (Mage = 12.42 years) and then examined whether reactivity and regulation interacted to influence the development of shyness over time. At Wave 1, shyness was related to higher levels of reactivity and lower levels of regulation at Wave 2, but neither reactivity nor regulation at Wave 1 predicted shyness at Wave 2. At Wave 2, shyness predicted greater reactivity at Wave 3, but shyness at Wave 3 was only predicted by lower levels of regulation at Wave 2. Contrary to the reactivity-regulation model of shyness, we found that relatively high levels of reactivity and low levels of regulation predicted a steep decrease in shyness over 3 years. These results are discussed in the context of the socioemotional difficulties experienced by shy individuals and demonstrate the importance of empirically evaluating long-standing models of personality development.

A person-centered examination of emotion dysregulation, sensitivity to threat, and impulsivity among children and adolescents: An ERP study.

OBJECTIVES: Adolescence often is characterized by the onset of social anxiety and risk taking; yet, not all youth are anxious and/or risk takers. There are several factors that may help differentiate youth with anxiety (e.g., threat sensitivity and emotion dysregulation) and youth who take risks (e.g., impulsivity and emotion dysregulation). We conducted a latent class analysis to identify groups of youth who differ in these processes, and then investigated group differences on the error-related negativity, an ERP that has been differentially associated with threat sensitivity and impulsivity. METHOD: Youth (N = 1313, Mage = 11, range = 8-15 years) completed a survey assessing their emotion dysregulation, sensitivity to threat, and impulsivity. A subsample (N = 424) also completed a go/no-go task while EEG was recorded. RESULTS AND CONCLUSIONS: Four groups were identified with differential levels of emotion dysregulation, sensitivity to threat, and impulsivity. Adolescents had greater odds than children of being in the High_Dysregulation/ThreatSensitivity or ModerateDysregulation/HighImpulsivity Groups in comparison to two other groups with lower scores. The High_Dysregulation/ThreatSensitivity Group had the largest ERN, while the ModerateDysregulation/HighImpulsivity Group had the smallest ERN. The ERN may be a potential biomarker to help distinguish between different profiles of adolescents who may be at risk for either anxiety or risk taking.

The role of pubertal status and sleep satisfaction in emotion reactivity and regulation in children and adolescents.

Study Objectives: This study investigated the role of pubertal status and hormones in the association between sleep satisfaction and self-reported emotion functioning in 256 children and adolescents aged 8-15. Methods: Self-report data was provided on sleep duration, sleep satisfaction, and emotion reactivity and regulation, and a saliva sample was obtained for hormone measures. A subset of children also wore an Actigraph watch to measure sleep for a week. Results: Latent-class analysis revealed three classes of sleepers: Satisfied, Moderately Satisfied, and Dissatisfied. Dissatisfied sleepers reported more difficulties with emotion regulation and greater emotion reactivity than Satisfied sleepers. High difficulties with emotion regulation was associated with shorter objective sleep duration, and high emotion reactivity was associated with lower sleep efficiency. For girls, Dissatisfied sleepers reported being further through pubertal development than Satisfied sleepers. There were also significant correlations between pubertal development and shorter sleep duration and longer sleep latency in girls, and shorter and more irregular sleep in boys. Finally, pubertal development in girls was a significant moderator in the relationship between sleep satisfaction and difficulties with emotion regulation in Dissatisfied sleepers, such that being further through puberty and having unsatisfactory sleep resulted in the highest emotion regulation difficulties. Conclusions: This study expands on previous literature by considering the role of sleep satisfaction and the interaction with puberty development on emotion function. Specifically, a role for pubertal development was identified in the association between unsatisfactory sleep and emotion regulation in girls.
