Identity Processes and Parent–Child and Sibling Relationships in Adolescence: A Five‐Wave Multi‐Informant Longitudinal Study

The purpose of this study was to examine reciprocal associations between identity processes (commitment, in‐depth exploration, and reconsideration of commitment) and dimensions (support, negative interaction, and power) of maternal, paternal, and sibling relationships. A total of 497 Dutch families including 14‐years‐old adolescents (56.9% males), their fathers, mothers, and siblings, for a total of 1,988 respondents, participated in a five‐wave longitudinal study. Cross‐lagged analyses indicated that commitment and in‐depth exploration predicted improvements in family relationships (unidirectional effects), whereas reconsideration of commitment was predicted by low levels of maternal support and worsened the quality of the paternal relationship (reciprocal effects). These results were not moderated by adolescents' gender and sibling characteristics. Theoretical and practical implications are discussed.     

A Six‐Year Longitudinal Study of Texting Trajectories During Adolescence

This study examined growth trajectories of texting (and other media) over a 6‐year time period. Participants were 425 adolescents from Washington, USA (age 13 at Time 1, age 18 at Time 6; 48% male, 68% European American). Analyses suggested a curvilinear pattern for texting and social media use, with rates peaking during midadolescence. There was also considerable heterogeneity in trajectories of texting. A growth mixture model revealed four distinct classes of individuals: perpetuals (14%), decreasers (7%), moderates (68%), and increasers (11%). Higher levels of depression, being a male, and coming from a single‐parent family predicted being a “perpetual” texter. Perpetuals had the most problematic outcomes compared to other classes, including higher depression, anxiety, aggression, and poor relationships with fathers.     

A Longitudinal Study of School Peer Networks and Adjustment to Middle School

A cohort of children was followed across the first 2 years of their middle school experience. Utilising a multi‐method, longitudinal research design, children's school peer networks were described as they moved from sixth to seventh grades. Next, predictive relations between these school peer network variables in sixth grade and seventh grade adjustment was determined. Results indicated that social groupings became more gender integrated from sixth to seventh grades. Further, adjustment can be explained in terms of children adjusting to gender roles.     

Academic and Psychological Functioning in Late Adolescence: The Importance of School Belonging

Few researchers have considered the influence of school context, an important construct at earlier ages, on late adolescents' college adjustment. In a sample of second-semester freshmen (N = 266), the authors explored associations between a sense of school belonging and academic and psychological adjustment. Students' reports of belonging at the university as well as in high school were both significant in predicting current academic (e.g., grades, academic competence) and psychological adjustment (i.e., self-worth, internalizing and externalizing problem behaviors), even after controlling for other important demographic and relationship factors. Last, the authors found that parental education (i.e., whether the participant was a first-generation college student) interacted with high school belonging in predicting externalizing problem behaviors.     

Orienting Attention Within Visual Short‐Term Memory: Development and Mechanisms

How does developing attentional control operate within visual short‐term memory (VSTM)? Seven‐year‐olds, 11‐year‐olds, and adults (total n = 205) were asked to report whether probe items were part of preceding visual arrays. In Experiment 1, central or peripheral cues oriented attention to the location of to‐be‐probed items either prior to encoding or during maintenance. Cues improved memory regardless of their position, but younger children benefited less from cues presented during maintenance, and these benefits related to VSTM span over and above basic memory in uncued trials. In Experiment 2, cues of low validity eliminated benefits, suggesting that even the youngest children use cues voluntarily, rather than automatically. These findings elucidate the close coupling between developing visuospatial attentional control and VSTM.     

Peer Reputation in Middle Childhood as a Predictor of Adaptation in Adolescence: A Seven-Year Follow-up

This investigation examines the predictive significance of peer reputation in elementary school for the quality of adaptation in adolescence. A normative sample (N = 207) of third to sixth graders was administered the Revised Class Play (RCP). Each received 3 scores (Sociability-Leadership, Aggression-Disruption, and Sensitivity-Isolation). 7 years later, 88% of these children and their parents participated in a questionnaire follow-up study utilizing a broad range of adolescent outcome measures (e.g., social and athletic competence, academic performance, behavioral symptoms, well-being). The 3 RCP scores were significantly related to both adolescent competence and psychopathology, supporting the predictive validity of the RCP as well as the continuity of general adaptation. Each dimension of peer reputation had a different pattern of prediction depending on the outcome criteria under consideration, suggesting the importance of a multidimensional approach to peer reputation. Positive peer reputation proved to be an important predictor of later adjustment. Sex differences were examined; results suggested somewhat different patterns of prediction for boys and girls, especially for the sensitive-isolated dimension.     

Family Influences on the Formation of Moral Identity in Adolescence: Longitudinal analyses

A model of moral identity formation is presented. According to the model, family influences have a direct effect on moral identity development in adolescence, independent of the effects of personality, income and other factors. The model is tested using longitudinal data from the National Longitudinal Survey of Youth (Child Sample), which is constituted of the children born to a representative sample of American women who were between the ages of 14 and 21 in 1979. In general, the results provide support for the model. Cognitively and socially rich family environments, combined with high levels of parent-adolescent joint activity, were found to facilitate voluntary participation in community service, a marker of moral identity formation. The implications of these findings for parenting, moral education and future research are discussed.     

A 5‐Year Longitudinal Study on Mood Variability Across Adolescence Using Daily Diaries

This study explored the development of mood variability in 474 Dutch adolescents (56.8% male, 90.1% medium to high socioeconomic status) from a community sample, followed from ages 13 to 18 years. Three times per year, adolescents reported on daily happiness, anger, sadness, and anxiety for 5 days using Internet diaries (15 assessment weeks; from 2006 to 2010). Mood variability scores were calculated as means of absolute differences between consecutive days. Results showed that happiness, anger, and sadness variability continuously declined across adolescence, while anxiety variability increased initially, then decreased, and then increased toward late adolescence. Despite females experiencing higher happiness and sadness variability, the rate of change across adolescence was similar for both sexes. Implications for normative emotional development and future studies are discussed.     

Diverse-and-Dynamic Pathways in Educational and Interpersonal Identity Formation during Adolescence: Longitudinal Links With Psychosocial Functioning

This study aimed to examine the relations between educational and interpersonal identity trajectories and psychosocial functioning based on a three-factor identity process model. A total of 968 Japanese adolescents including 13- and 16-years-olds (49.7% female) participated in a four-wave longitudinal study. Latent class growth analysis extracted five identity trajectories in each educational and interpersonal identity domain and revealed (a) high prevalence of low commitment identity trajectories, (b) absence of the closure trajectory, and (c) changeable identity trajectories that have not been identified in Western context (i.e., the Netherlands). Furthermore, a latent change model revealed dynamic relations between identity trajectories and psychosocial functioning. These findings provide critical insights into the diverse and dynamic pathways of identity formation during adolescence in Japan.     

Self-Restraint as a Mediator of Family Influences on Boys' Delinquent Behavior: A Longitudinal Study

In the course of social development, family influences seem to become partly internalized and transformed into personality characteristics that regulate behavior outside the family sphere. In a longitudinal study of 81 boys and their families, we hypothesized that individual differences in boys' self-restraint would serve as a mediator between family factors in preadolescence and sons' delinquent behavior 4 years later. Measures were derived from principal components analyses of multiple indices of each construct as assessed by multiple informants. As expected, parenting practices measured at both pre- and mid-adolescence predicted delinquent acts only indirectly via their association with boys' self-restraint. In addition, general family functioning at preadolescence, independent of other scores, predicted boys' levels of self-restraint 4 years later. There was no evidence that boys' self-restraint at preadolescence systematically affected the quality of parenting that they subsequently received. Parents' and families' role in children's development of self-regulatory skills may be a primary vehicle by which they ultimately influence adolescents' problem behaviors.     

Academic Self-Perceptions and Academic Achievement in Chinese Children: A Multiwave Longitudinal Study

This study examined reciprocal contributions between academic self-perceptions and academic achievement. Data were collected each year in four consecutive years from a sample of children in China (initial N = 1,156; 581 boys; initial M_age = 9.33 years). Analyses using random intercept cross-lagged panel models revealed that the effects of academic achievement on self-perceptions tended to be more evident in lower grades and the effects of academic self-perceptions on achievement tended to be more evident in higher grades. Latent growth curve analyses showed that the initial level of academic self-perceptions and achievement moderated the growth of each other. The results indicate the contributions between academic self-perceptions and achievement that occur in a progressive cascading manner in Chinese children.     

Peer Influence Via Instagram: Effects on Brain and Behavior in Adolescence and Young Adulthood

Mobile social media often feature the ability to “Like” content posted by others. This study examined the effect of Likes on youths' neural and behavioral responses to photographs. High school and college students (N = 61, ages 13–21) viewed theirs and others' Instagram photographs while undergoing functional Magnetic Resonance Imaging (fMRI). Participants more often Liked photographs that appeared to have received many (vs. few) Likes. Popular photographs elicited greater activity in multiple brain regions, including the nucleus accumbens (NAcc), a hub of the brain's reward circuitry. NAcc responsivity increased with age for high school but not college students. When viewing images depicting risk‐taking (vs. nonrisky photographs), high school students, but not college students, showed decreased activation of neural regions implicated in cognitive control.     

Prosocial and Aggressive Behavior: A Longitudinal Study

Developmental theorists have made strong claims about the fundamental prosocial or aggressive nature of the human infant. However, only rarely have prosocial behavior and aggression been studied together in the same sample. We charted the parallel development of both behaviors from infancy to childhood in a British community sample, using a two-construct, multimethod longitudinal design. Data were drawn from the Cardiff Child Development Study (CCDS), a prospective longitudinal study of a volunteer sample of parents and their firstborn children. A sample of 332 mothers was recruited from National Health Service (NHS) prenatal clinics and general practice clinics in Wales, UK, between Fall of 2005 and Summer of 2007. Potential participants represented the full range of sociodemographic classifications of neighborhoods. Participating families were divided about equally between middle- and working-class families, were somewhat more likely to have sons than daughters, and the majority (90%) were in a stable partnership. In response to standard categories recommended for use in Wales at the time, the majority (93%) of mothers reported themselves as Welsh, Scottish, English, or Irish; most others named a European or South Asian nationality. Of the 332 families agreeing to participate, 321 mothers (M_age = 28 years) and 285 partners (M_age = 31 years) were interviewed during the pregnancy and 321 of the families contributed data at least once after the child's birth. After an initial home visit at 6 months, data collection occurred in four additional waves of testing when children's mean ages were approximately 1, 1.5, 2.5, and 7 years. Data collection alternated between family homes and Cardiff University. Of those families seen after the child's birth, 89% were assessed at the final wave of testing. Data collection ended in 2015. Methods included direct observation, experimental tasks, and collection of reports from mothers, fathers, other relatives or family friends, and classroom teachers. Interactions with a familiar peer were observed at 1.5 years. Interactions with unfamiliar peers took place during experimental birthday parties at 1 and 2.5 years. At 7 years, parents were interviewed, parents and teachers completed questionnaires, and the children engaged in cognitive and social decision-making tasks. Based on reports from parents and other informants who knew the children well, individual differences in both prosocial behavior and aggression were evident in children. Both types of behavior showed stability across the second and third years. The association between prosocial behavior and aggression changed over time: at 1.5 years, they were not significantly related (the association approached zero), but they became negatively correlated by 3 years. Different patterns were seen when children played with familiar versus unfamiliar peers. At 1.5 years, when children were observed at home with a familiar peer, prosocial behavior and aggression were unrelated, thus showing a pattern of results like that seen in the analysis of informants' reports. However, a different pattern emerged during the experimental birthday parties with unfamiliar peers: prosocial behavior and aggression were positively correlated at both 1 and 2.5 years, contributing to a general sociability factor at both ages. Gender differences in prosocial behavior were evident in informants' reports and were also evident at the 1-year (though not the 2.5-year) birthday parties. In contrast, gender differences in both prosocial behavior and aggression were evident by 7 years, both in children's aggressive decision-making and in their parents' and teachers' reports of children's aggressive behavior at home and school. By age 7, children's aggressive decision-making and behavior were inversely associated with their verbal skills, working memory, and emotional understanding. Some children had developed aggressive behavioral problems and callous-unemotional traits. A few (12%) met diagnostic criteria for conduct disorder or oppositional-defiant disorders, which had been predicted by early angry aggressiveness and lack of empathy for other people. Taken together, the findings revealed a gradual disaggregation of two ways in which children interact with other people. Individual differences in both prosocial behavior and aggression revealed continuity over time, with gender differences emerging first in prosocial behavior, then in aggression. Restrictions in the participant sample and the catchment area (e.g., all were first-time parents; all were drawn from a single region in the United Kingdom) mean that it is not possible to generalize findings broadly. It will be important to expand the study of prosocial behavior and aggression in other family and environmental contexts in future work. Learning more about early appearing individual differences in children's approaches to the social world may be useful for both educational and clinical practice.     

The Role of Emotionality and Regulation in Children's Social Functioning: A Longitudinal Study

Multiple measures of children's emotionality (emotional intensity and negative affectivity), regulation (including attentional and behavioral regulation and coping), and social functioning (teachers' reports of nonaggressive/socially appropriate behavior and prosocial/socially competent behavior; and parents' reports of problem behavior) were obtained for 6–8-year-olds. In addition, emotionality, attentional regulation, and coping were assessed 2 years previously. Social functioning was expected to be predicted by low negative emotionality and high levels of regulation. In general, the data supported the predictions, although the findings for parent reports of problem behavior were primarily for boys. Prediction of social functioning from measures of regulation and emotionality occurred primarily within a given context (school vs. home) rather than across contexts, even though there were relations across reporters within the school or home context. In addition, vagal tone, a marker of physiological regulation, was positively related to competent social functioning and emotionality/regulation for boys, but inversely related for girls.     

Visual Short‐Term Memory for Complex Objects in 6‐ and 8‐Month‐Old Infants

Infants' visual short‐term memory (VSTM) for simple objects undergoes dramatic development: Six‐month‐old infants can store in VSTM information about only a simple object presented in isolation, whereas 8‐month‐old infants can store information about simple objects presented in multiple‐item arrays. This study extended this work to examine the development of infants' VSTM for complex objects during this same period (N = 105). Using the simultaneous streams change detection paradigm, Experiment 1 confirmed the previous developmental trajectory between 6 and 8 months. Experiment 2 showed that doubling the exposure time did not enhance 6‐month‐old infants' change detection, demonstrating that the developmental change is not due to encoding speed. Thus, VSTM for simple and complex objects appears to follow the same developmental trajectory.     

Reciprocal Relations Between Harsh Discipline and Children's Externalizing Behavior in China: A 5‐Year Longitudinal Study

This research examined the overtime reciprocal relations between maternal and paternal harsh discipline and children's externalizing behavior. Seven hundred two father–mother dyads of children (6–9 years of age at baseline) completed measures of parental harsh discipline and children's externalizing behavior at five time points, 1 year apart. Autoregressive latent trajectory models revealed that maternal and paternal corporal punishment predicted subsequent children's externalizing behavior (parent‐driven effects), whereas children's externalizing behavior predicted subsequent maternal and paternal psychological aggression (child‐driven effects). The parent‐driven effects became stronger, whereas the child‐driven effects were equally strong across time. Furthermore, the parent‐driven effects for corporal punishment were found for both boys and girls, whereas the child‐driven effects for psychological aggression were found only for boys.     

Autism-Related Variation in Reciprocal Social Behavior: A Longitudinal Study

Deficits in reciprocal social behavior are a characterizing feature of autism spectrum disorder (ASD). Autism-related variation in reciprocal social behavior (AVR) in the general population is continuously distributed and highly heritable—a function of additive genetic influences that overlap substantially with those which engender clinical autistic syndromes. This is the first long-term prospective study of the stability of AVR from childhood through early adulthood, conducted via serial ratings using the Social Responsiveness Scale, in a cohort-sequential study involving children with ASD, other psychiatric conditions, and their siblings (N = 602, ages = 2.5–29). AVR exhibits marked stability throughout childhood in individuals with and without ASD.     

Short‐Term Second Language and Music Training Induces Lasting Functional Brain Changes in Early Childhood

Immediate and lasting effects of music or second‐language training were examined in early childhood using event‐related potentials. Event‐related potentials were recorded for French vowels and musical notes in a passive oddball paradigm in thirty‐six 4‐ to 6‐year‐old children who received either French or music training. Following training, both groups showed enhanced late discriminative negativity (LDN) in their trained condition (music group–musical notes; French group–French vowels) and reduced LDN in the untrained condition. These changes reflect improved processing of relevant (trained) sounds, and an increased capacity to suppress irrelevant (untrained) sounds. After 1 year, training‐induced brain changes persisted and new hemispheric changes appeared. Such results provide evidence for the lasting benefit of early intervention in young children.     

Predicting Academic Success: A Longitudinal Study of University Design Students

This article presents a longitudinal study, over eleven years, of the academic progress of a cohort of design students (n = 475) at a major Australian university. The students were from four different spatial design disciplines: architecture, industrial design, interior design, and landscape architecture. The article identifies cognitive variables that may predict future academic success. This research uses regression analysis to identify correlations across a range of variables, in particular exploring the relationship between university entrance scores, subjects studied at school (art and graphics) and academic success as defined by university grade point average and time to completion. This study shows that prior knowledge in art and graphics is not a useful predictor of future academic success, while university entrance scores and first year performance are related to ongoing academic success. These results suggest that for the design disciplines explored here, discipline‐specific prior knowledge is not an important requirement for university entrance.     

The Relationship of Client Stages of Change to Working Alliance and Outcome in Short‐Term Counseling

This study evaluated the relationship of J. O. Prochaska's (1984; J. O. Prochaska & C. C. DiClemente, 1992) transtheoretical model of change with the process and outcome of short‐term counseling in college help seekers. Participants completed measures of readiness to change, psychological symptoms, and working alliance. Clients in the precontemplation stage evaluated the working alliance less favorably and experienced less improvement regarding symptoms than clients in other stages. Counselor working alliance did not differ as a function of clients' stage of change.
