Antisocial Behavior,Psychopathic Features and Abnormalities in Reward and Punishment Processing in Youth

A better understanding of what leads youth to initially engage in antisocial behavior (ASB) and more importantly persist with such behaviors into adulthood has significant implications for prevention and intervention efforts. A considerable number of studies using behavioral and neuroimaging techniques have investigated abnormalities in reward and punishment processing as potential causal mechanisms underlying ASB. However, this literature has yet to be critically evaluated, and there are no comprehensive reviews that systematically examine and synthesize these findings. The goal of the present review is twofold. The first aim is to examine the extent to which youth with ASB are characterized by abnormalities in (1) reward processing; (2) punishment processing; or (3) both reward and punishment processing. The second aim is to evaluate whether aberrant reward and/or punishment processing is specific to or most pronounced in a subgroup of antisocial youth with psychopathic features. Studies utilizing behavioral methods are first reviewed, followed by studies using functional magnetic resonance imaging. An integration of theory and research across multiple levels of analysis is presented in order to provide a more comprehensive understanding of reward and punishment processing in antisocial youth. Findings are discussed in terms of developmental and contextual considerations, proposed future directions and implications for intervention.     

Novel Insights into Longstanding Theories of Bidirectional Parent–Child Influences: Introduction to the Special Section

Although bidirectional parent and child influences have been incorporated in theoretical models pertaining to the development of internalizing and externalizing behaviors in youth, studies have historically focused on the socializing influence that parents have on their children. This has left several important research questions unanswered about the nature of bidirectional parent-child relations across development, including how these bidirectional effects are related to different types of child and adolescent psychopathology. The goal of this special section is to examine some longstanding issues regarding the nature of bidirectional parent-child effects across time using a diverse array of longitudinal datasets. The results from these studies emphasize the importance of considering bidirectional effects in developmental psychopathology research, particularly the often overlooked influence that children and adolescents have on their parents' behavior and emotional well-being. Following these empirical articles, an expert in the field provides a scholarly commentary designed to outline the progress that has been made in understanding bidirectional parent-child effects across development as well as to propose fruitful areas for future research.     

Comparing factor structures of adolescent psychopathology

Research on the structure of adolescent psychopathology can provide information on broad factors that underlie different forms of maladjustment in youths. Multiple studies from the literature on adult populations suggest that 2 factors, Internalizing and Externalizing, meaningfully comprise the factor structure of adult psychopathology (e.g., Krueger, 1999) and presumably represent broad vulnerability for co-occurring disorders. Though this research was partially inspired by early work with children and adolescents (e.g., Achenbach & Edelbrock, 1984), the role of substance use in these models of youth psychopathology has not been fully explored. Toward this goal, we recruited 223 youths (10-17 years of age, M = 14.2) from mental health agencies and the community. We found evidence for a 3-factor model of youth psychopathology, including Internalizing (depression, generalized anxiety), Externalizing (conduct disorder, attention deficit, oppositional defiant disorder), and Substance Use (alcohol and cannabis). The 3-factor model showed the best fit to the data relative to other factor models tested, including across subsamples of adolescents who differed on level of psychopathology (treatment vs. community samples). Implications for the structure of adolescent psychopathology, including important developmental considerations, are discussed.     

Functional neuroimaging in neurology and psychiatry

How can functional neuroimaging be applied to clinical neurology and psychiatry? This article reviews selected contributions of functional neuroimaging to the clinical neurosciences. We review selected technical aspects of positron emission tomography, single photon emission tomography, and functional magnetic resonance imaging with a focus on the relative strengths and weaknesses of these techniques. Consumers of functional neuroimaging research are encouraged to consider the limitations of imaging techniques and theoretical pitfalls of cognitive task design when interpreting results of functional imaging studies. Then, we selectively review the contributions of functional neuroimaging to neurology and psychiatry, including the areas of epilepsy, stroke, chronic pain, schizophrenia, depression, and obsessive-compulsive disorder. Future directions of functional neuroimaging research are offered, with the emphasis that the best conclusions are informed by a convergence of research from functional neuroimaging, neurophysiological, and lesion studies.     

Neuroimaging of emotion and personality: scientific evidence and ethical considerations

Affective neuroscience has seen an explosion of research efforts using modern neuroimaging approaches to uncover the neural basis of emotion and personality. The first section of this paper reviews studies from the domains of affective and forensic neuroimaging. These studies illustrate some of the topics likely to be the subject of future ethical debates. The second section relates limitations of the neuroimaging approach to ethical considerations in predicting future psychopathology on the basis of brain state analysis.     

Child and Adolescent Emotion Regulation: The Role of Parental Emotion Regulation and Expression

This paper reviews current literature relating to parent and child emotional functioning, specifically their emotion regulatory skills and emotional expression. Included are considerations regarding theoretical, methodological, and sampling strengths and weaknesses of existing literature. On the basis of the review, several directions for future research are proposed. First, it is argued that consistency in the measurement of emotion regulation is necessary, including assessment of more refined theoretical conceptualizations of regulatory types, skills, or strategies. Second, it is argued that emotion regulation developmental research examining the post-early childhood period is necessary in order to contribute to a more comprehensive understanding of youths’ emotion regulation. Finally, it is argued that greater examination of paternal influences on child emotional functioning, in addition to maternal influences, is required. Consideration of these issues in future emotion regulation research will ideally contribute to a greater understanding of the mechanisms involved in child and adolescent development of optimal regulatory capacities.

Rates of suicide among males increase steadily from age 11 to 21: Developmental framework and outline for prevention

The paper has three purposes. First, explanations for the steady age-related increase in the rate of suicide among male youth from ages 11 to 21 are offered based on a review of epidemiological- and case-control evidence. It is concluded that depression and substance use disorders are major contributors to the age-related pattern in suicide. A general increased capacity for serious acts of aggression from ages 11 to 21 might also contribute to this pattern in suicide. Second, evidence that substance abuse and depression both contribute to, and are exacerbated by, difficulties in negotiating age-salient tasks is summarized. In this context, suicides among young males are posited to mark the endpoint of the bidirectional interplay of psychopathology and developmental difficulties. Third, informed by this developmental perspective, the authors make recommendations to reduce suicides in male youth, emphasizing strategies that may interrupt cycles of depression and/or substance abuse and developmental failure. Strategies to reduce the potential for fatalities, notably method restrictions, are also discussed.     

The evolutionary basis of risky adolescent behavior: implications for science, policy, and practice

This article proposes an evolutionary model of risky behavior in adolescence and contrasts it with the prevailing developmental psychopathology model. The evolutionary model contends that understanding the evolutionary functions of adolescence is critical to explaining why adolescents engage in risky behavior and that successful intervention depends on working with, instead of against, adolescent goals and motivations. The current article articulates 5 key evolutionary insights into risky adolescent behavior: (a) The adolescent transition is an inflection point in development of social status and reproductive trajectories; (b) interventions need to address the adaptive functions of risky and aggressive behaviors like bullying; (c) risky adolescent behavior adaptively calibrates over development to match both harsh and unpredictable environmental conditions; (d) understanding evolved sex differences is critical for understanding the psychology of risky behavior; and (e) mismatches between current and past environments can dysregulate adolescent behavior, as demonstrated by age-segregated social groupings. The evolutionary model has broad implications for designing interventions for high-risk youth and suggests new directions for research that have not been forthcoming from other perspectives.     

Does controlling for comorbidity matter? DSM‐oriented scales and violent offending in chicago youth

Mental health problems have long been linked to antisocial behaviors. Despite an impressive body of literature demonstrating this relationship and claims that comorbidity matters, few studies examine comorbidity using multiple distinct mental health indicators, with most studies instead adopting single or composite mental health measures. This study tested separate and comorbid effects of five DSM‐oriented mental health issues on self‐reported violence using a community‐based sample of Chicago youths from the Project on Human Development in Chicago Neighborhoods. Moreover, it utilized both primary caregiver and youth self‐reports of psychopathology across four developmental stages of childhood and adolescence. When examined separately, the results indicated affective/depressive, anxiety, attention deficit hyperactivity, and oppositional defiant/antisocial personality problems independently predicted violence. When considering comorbidity, however, only oppositional defiant and antisocial personality problems significantly predicted violence at any stage, regardless of informant type. Implications for future studies and policy are discussed. Aggr. Behav. 36:141–157, 2010. © 2010 Wiley‐Liss, Inc.     

The multiple neural networks of familiarity: A meta-analysis of functional imaging studies

Recent research has demonstrated the critical role of the feeling of familiarity in recognition memory. Various neuroimaging paradigms have been developed to identify the brain regions that sustain the processing of familiarity; however, there is still considerable controversy about the functional significance of each brain region implicated in familiarity-based retrieval. Here, we focused on the differences between paradigms that assess familiarity, with or without the encoding phase. We used the activation likelihood estimation (ALE) algorithm to conduct a whole-brain meta-analysis of neuroimaging studies that involved a familiarity task. Sixty-nine studies, performed in healthy subjects to determine the specific functions of the identified regions in familiarity processing, were finally selected. Distinct subanalyses were performed according to the experimental procedures used in the original studies. The ALE clusters that were highlighted revealed common activations for paradigms with and without encoding in the prefrontal cortex and in the parietal cortex. Additionally, supplementary activations related to specific familiarity (i.e., without the encoding phase) were observed in the limbic system (i.e., the amygdala, hippocampus, cingulate cortex, and insula) and in the associative sensory areas. The differences in the reported findings for different procedures are possibly due to differences in the concept of familiarity. To aid the exploration of the neural correlates of familiarity in future studies, the strengths and weaknesses of these experimental procedures are critically discussed.     

Toward an integrative and collaborative approach to Asian American and Pacific Islander youth violence research, practice, and policy

Research into the prevalence of violence and delinquency among Asian American and Pacific Islander (AAPI) youth has proliferated in the last several years, as a result of federal funding. Consequently, this article reviews the literature on AAPI youth violence and delinquency published from 2001 to 2008. The findings demonstrate the frequency of AAPI youth violence and delinquency, provide a sense of the involvement of these youth in the juvenile justice system, reveal ethnic group differences in violence and delinquency, and explore the effects of immigration and acculturation on these phenomena. This article ends with a discussion on AAPI youth violence and delinquency prevention programs, with suggestions for future directions that incorporate a developmental and life-course approach in research and collaboration among researchers, practitioners, and policymakers.     

Acculturation and Latino Adolescent Mental Health: Integration of Individual,Environmental, and Family Influences

In order to address the mental health disparities that exist for Latino adolescents in the United States, psychologists must understand specific factors that contribute to the high risk of mental health problems in Latino youth. Given the significant percentage of Latino youth who are immigrants or the children of immigrants, acculturation is a key factor in understanding mental health among this population. However, limitations in the conceptualization and measurement of acculturation have led to conflicting findings in the literature. Thus, the goal of the current review is to examine and critique research linking acculturation and mental health outcomes for Latino youth, as well as to integrate individual, environmental, and family influences of this relationship. An integrated theoretical model is presented and implications for clinical practice and future directions are discussed.     

Psychopathy in Children and Adolescents: The Need for a Developmental Perspective

The current paper introduces the special issue on research attempting to extend the construct of psychopathy to child and adolescent samples. Past special sections and reviews have typically focused on the implications of this research for forensic research and practice. The current special issue focuses on topics relevant for integrating this research within the broader literature on childhood psychopathology. Papers included in this special issue focus on the structure of psychopathic traits in youth, the relation of these traits to other important psychopathological and personality constructs in children and adolescents, and the utility of these traits for identifying a distinct subgroup of antisocial youth who differ on important cognitive processes and on the severity and stability of their problem behavior. These empirical works are followed by commentary provided by two prominent scholars who outline the potential importance of the construct for advancing our understanding of childhood psychopathology. In addition, these scholars provide a discussion of important directions for future research.     

Choosing Assessment Instruments for Depression Outcome Research With School‐Age Youth

Using effect size results from Erford et al.'s (2011) meta‐analysis for treatment of depression in school‐age youth, the authors analyzed 6 commonly used instruments for practical and technical strengths and weaknesses. Effect size estimates from these 6 instruments were compared to indicate likely results when used in future depression outcome research.     

Neuroanatomical substrates of social cognition dysfunction in autism

In this review article, we summarize recent progress toward understanding the neural structures and circuitry underlying dysfunctional social cognition in autism. We review selected studies from the growing literature that has used the functional neuroimaging techniques of cognitive neuroscience to map out the neuroanatomical substrates of social cognition in autism. We also draw upon functional neuroimaging studies with neurologically normal individuals and individuals with brain lesions to highlight the insights these studies offer that may help elucidate the search for the neural basis of social cognition deficits in autism. We organize this review around key brain structures that have been implicated in the social cognition deficits in autism: (1) the amygdala, (2) the superior temporal sulcus region, and (3) the fusiform gyrus. We review some of what is known about the contribution of each structure to social cognition and then review autism studies that implicate that particular structure. We conclude with a discussion of several potential future directions in the cognitive neuroscience of social deficits in autism.     

A Review of Factors that Promote Resilience in Youth with ADHD and ADHD Symptoms

The vast majority of research on youth with ADHD has focused on risk factors and describing the types of impairment individuals with ADHD experience. However, functional outcomes associated with ADHD are heterogeneous, and although many youth with ADHD experience significant negative outcomes (e.g., school dropout), some are successful in multiple domains of functioning (e.g., pursue and graduate college). There is a growing body of literature supporting the existence of factors that protect youth with ADHD from experiencing negative outcomes, but there is no published synthesis of this literature. Accordingly, the goals of this review are to conceptualize risk–resilience in the context of ADHD using a developmental psychopathology framework and to systematically review and critique evidence for promotive and protective factors in the context of ADHD. The literature search focused specifically on resilience in the context of ADHD symptoms or an ADHD diagnosis and identified 21 studies, including clinic, school, and community samples. Findings of promotive and/or protective factors are summarized across individual, family, and social–community systems. Overall, we know very little of the buffering processes for these youth, given that the study of promotive and protective factors in ADHD is in its infancy. The strongest evidence to date was found for social- and family-level systems. Specifically, multiple longitudinal studies support social acceptance as a protective factor, buffering against negative outcomes such as poor academic performance and comorbid depressive symptoms for youth with ADHD. There was also compelling evidence supporting positive parenting as a promotive factor. In terms of individual-level factors, positive or modest self-perceptions of competence were identified as a promotive factor in multiple studies. Future directions for research that will catalyze the study of resilience with ADHD are provided, and the potential for targeting protective mechanisms with intervention and prevention is discussed.     

Co-occurring Mental Health Problems and Peer Functioning Among Youth with Attention-Deficit/Hyperactivity Disorder: A Review and Recommendations for Future Research

It is well established that children and adolescents with attention-deficit/hyperactivity disorder (ADHD) frequently experience co-occurring mental health problems in addition to difficulties in their peer relationships. Although substantial research has focused on the extent to which peer functioning contributes to subsequent co-occurring mental health problems, much less research has considered how co-occurring mental health problems affect peer functioning domains. Therefore, the purpose of this review is to examine the effect of co-occurring mental health problems on the peer functioning of youth with ADHD. The impact of co-occurring externalizing (i.e., oppositional defiant disorder, conduct disorder) and internalizing (i.e., anxiety, depression) symptoms are reviewed, with a focus on whether these co-occurring symptoms exacerbate, attenuate, or have no effect across peer domains of social skills/competence, peer status, and friendship among youth with ADHD. Drawing from a developmental psychopathology framework, this review then draws attention to relevant causal processes and developmental cascades (including social-cognitive, affective, and family and parenting factors) in offering promising avenues for future work.     

Executive functioning in preschool children: performance on A-not-B and other delayed response format tasks

The A-not-B (AB) task has been hypothesized to measure executive/frontal lobe function; however, the developmental and measurement characteristics of this task have not been investigated. Performances on AB and comparison tasks adapted from developmental and neuroscience literature was examined in 117 preschool children (ages 23-66 months). Age significantly predicted performance on AB, Delayed Alternation, Spatial Reversal, Color Reversal, and Self-Control tasks. A four-factor analytic model best fit task performance data. AB task indices loaded on two factors with measures from the Self-Control and Delayed Alternation tasks, respectively. AB indices did not load with those from the reversal tasks despite similarities in task administration and presumed cognitive demand (working memory). These results indicate that AB is sensitive to individual differences in age-related performance in preschool children and suggest that AB performance is related to both working memory and inhibition processes in this age range.     

A review of the literature on Pacific Island youth offending in New Zealand

This review examines the current literature on Pacific youth offending in New Zealand. Pacific Island youth offenders are over-represented in the rates of violent offenses, despite not being overly represented in youth offending statistics. A major concern is that the Pacific population has the largest percentage of children and young people under 15 years old in New Zealand. Therefore, this is an issue to be faced by Pacific and wider communities in New Zealand. We focus on risk factors of offending, and its current impacts on Pacific Island youth in New Zealand. A literature review was conducted to explore some of the risk factors for offending looking at New Zealand studies and government reports. This was followed by a review of overseas literature regarding Pacific youths and their offending behavior. Following this, ethnic minorities were included in the literature review from New Zealand and international perspectives. Expectedly, results in this area are sparse. However, a number of efforts have been made to address this gap in the literature which this review included. The findings in this review make future recommendations for Pacific youth with offending behavior. These include that ethnicity should be taken into account when addressing research on youth offenders; data relating to the youth offender such as social and demographic history should also be considered for a more collaborative approach to researching and understanding this population; and more targeted studies towards this population are needed to improve the overall health of the Pacific Island population in New Zealand and overseas. Finally, existing programs and interventions currently in place for our Pacific youths with offending behavior needs to be evaluated to ensure it continues to meet the dynamic needs of our Pacific youth population.
