A defensive mindset: A pattern of social information processing that develops early and predicts life course outcomes

Hostile cognitions and emotions following social exclusion in Japanese adults and young children

Social exclusion heightens negative emotions and hostile cognition toward others; however, its effects on non-Western adults and children remain unclear. These studies examined the effects on Japanese adults (N = 68; 34 female; Mage = 21.87 years) and 4- to 6-year-old children (N = 147; 78 female). The results showed that although excluded adults reported higher negative emotions and hostile evaluations of excluders, hostile cognitions toward others did not differ significantly between the inclusion and exclusion conditions. Excluded older children reported higher hostile evaluations toward excluders; however, emotions and hostile cognitions toward others did not differ significantly between the conditions. Although developmental changes in emotions and hostile evaluations were suggested, this research partially contradicts previous Western findings, highlighting the need for cross-cultural research.

Rumination Mediates the Relation of Hostile Attribution to Psychological Maladjustment Among Adolescents from Three Countries

Addressing global concerns about youth mental health requires understanding longitudinal pathways to psychological maladjustment among diverse youth. Hostile attribution bias (HAB) and hostile rumination (HR) are cognitive vulnerabilities associated with multiple forms of psychological maladjustment among diverse youth. This study longitudinally examined whether HR mediates the relation of HAB to aggression, anxiety, and depression symptoms in a sample of adolescents from three countries. Participants included 532 mothers, 384 fathers, and 566 youth (50% female) from Colombia, Italy (Naples and Rome), and the U.S. (White, Black, and Latinx). Structural equation modeling indicated that youth-reported HR at Time 2 (mean age = 12.58 years) significantly mediated the relation of youth-reported HAB at Time 1 (mean age = 10.89 years) to parent-reported aggression and anxiety symptoms at Time 3 (mean age = 13.71 years; aggression: b = 0.05, 95% bootstrap CI = [0.006, 0.14]; anxiety: b = 0.06, 95% bootstrap CI = [0.01, 0.16]); but not to parent-reported depression symptoms at Time 3 (b = 0.02, 95% bootstrap CI = [-0.04, 0.08]). A reverse model indicated HAB at Time 3 significantly mediated the relation of HR at Time 2 to anxiety symptoms at Time 4 (mean age = 14.99 years; b = -0.01, 95% bootstrap CI = [-0.04, -0.001]), but not to aggression or depression symptoms at Time 4. Multi-group analyses indicated focal mediational paths did not vary significantly across national, regional, and racial subgroups or gender. Findings support the Integrative Cognitive Model of Aggression, providing evidence that HAB and HR may be vulnerability factors for aggression and anxiety among diverse youth.

Developmental psychopathology: Our welcoming, inclusive, and eclectic intellectual home

The integrative nature of developmental psychopathology is its defining and most remarkable feature. Since its inception, often identified with the special issue of Child Development (Cichetti, 1984), this new discipline has shattered barriers and divisions that until then had artificially compartmentalized the study of human development, and perhaps even psychology in general, and it has proposed new ways of integrative thinking about development. One, developmental psychopathology has programmatically integrated research on typical or adaptive and atypical or maladaptive developmental processes and demonstrated how those inform each other. Two, developmental psychopathology has promoted bridges between developmental research and other disciplines. Three, less explicitly but equally importantly, developmental psychopathology has abolished conceptual and empirical barriers that had existed among various theories and perspectives within developmental psychology by creating a welcoming niche for research inspired by theories often historically seen as contradictory or incompatible. Ideas originating in psychoanalytic, learning, cognitive, ethological, and sociocultural theories all find a welcoming home and seamlessly coexist in heuristically productive harmony within developmental psychopathology, inform each other, and generate exciting questions and insights. This eclectic and conceptually inclusive nature is one reason for developmental psychopathology's lasting appeal and inspirational power.

How a defensive mindset develops from early adverse experiences and guides antisocial outcomes

Dante Cicchetti has had a lasting impact on our understanding of the development of externalizing psychopathology through at least two seminal contributions, including establishment of the field of developmental psychopathology and assertion of the hypothesis that early physical abuse and neglect trigger a cascade of maladaptive outcomes across the life course. These ideas have guided a program of research on children's deviant social information processing and defensive mindset as the psychological mechanisms through which early physical abuse leads to long-term psychopathology. Longitudinal studies following children from early life through mid-adulthood show that physical abuse in the first five years of life leads children to adopt a defensive mindset that, in turn, cascades into long-term outcomes of externalizing psychopathology, incarceration, and dysfunction. Cicchetti's ideas have also guided the development of preventive interventions to interrupt this life course.

Expanding understanding of adolescent neural sensitivity to peers: Using social information processing theory to generate new lines of research

Adolescence is a period of normative heightened sensitivity to peer influence. Individual differences in susceptibility to peers is related to individual differences in neural sensitivity, particularly in brain regions that support an increasingly greater orientation toward peers. Despite these empirically-established patterns, the more specific psychosocial and socio-cognitive factors associated with individual differences in neural sensitivity to peer influence are just beginning to gain research attention. Specific features of the factors that contribute to how adolescents process social information can inform understanding of the psychological and neurobiological processes involved in what renders adolescents to be more or less susceptible to peer influences. In this paper, we (1) review the literature about peer, family, and broader contextual influences on sensitivity to peers' positive and negative behaviors, (2) outline components of social information processing theories, and (3) discuss features of these models from the perspectives and social cognitive development and social neuroscience. We identify gaps in the current literature that need to be addressed in order to gain a more comprehensive view of adolescent neural sensitivity to peer influence. We conclude by suggesting how future neuroimaging studies can adopt components of this social information processing model to generate new lines of research.

The Relationship Between Hostile Intent Attribution and Aggression in Japanese Children

Previous studies showed that hostile intent attribution (HIA) was significantly correlated with and contributed to the development of aggression in children. Studies that directly examined the factors that explained the relationship between HIA and aggression are lacking. Hence, this study investigated (a) the correlation between HIA and aggression and (b) the variables (hyperactivity, prosociality, and collaborative problem-solving) that mediated the relationship between HIA and aggression in Japanese children aged 4-9 years. The participants were 180 children and their caregivers. First, the caregivers reported their children's aggression, hyperactivity, prosociality, and collaborative problem-solving through questionnaires. Next, the children worked on an HIA task. The results showed a weak positive correlation between HIA and aggression. Furthermore, significant indirect effects were observed among all the mediation models. The model that contained all three mediators yielded the smallest Akaike Information Criterion value. In this model, the indirect effect was significant only for the path with hyperactivity as the mediator. These findings provide several suggestions for revealing the mechanism of the relationship between HIA and aggression during childhood. Notably, children's hyperactivity was suggested to play a particularly important role in the relationship between HIA and aggression.

A neurocognitive model of early onset persistent and desistant antisocial behavior in early adulthood

It remains unclear which functional and neurobiological mechanisms are associated with persistent and desistant antisocial behavior in early adulthood. We reviewed the empirical literature and propose a neurocognitive social information processing model for early onset persistent and desistant antisocial behavior in early adulthood, focusing on how young adults evaluate, act upon, monitor, and learn about their goals and self traits. Based on the reviewed literature, we propose that persistent antisocial behavior is characterized by domain-general impairments in self-relevant and goal-related information processing, regulation, and learning, which is accompanied by altered activity in fronto-limbic brain areas. We propose that desistant antisocial development is associated with more effortful information processing, regulation and learning, that possibly balances self-relevant goals and specific situational characteristics. The proposed framework advances insights by considering individual differences such as psychopathic personality traits, and specific emotional characteristics (e.g., valence of social cues), to further illuminate functional and neural mechanisms underlying heterogenous developmental pathways. Finally, we address important open questions and offer suggestions for future research to improve scientific knowledge on general and context-specific expression and development of antisocial behavior in early adulthood.
