The church studies its emerging function

This article appeared originally in the Journal of Social Issues, published by the Society for the Psychological Study of Social Issues (a division of the American Psychological Association) and is published by permission of the editor and the author. The entire issue of that quarterly was devoted to the theme of psychotherapy and group counseling by the various helping professions. In commenting on Dr. Cope's particular article, the editors of the issue said: We feel that Dr. Cope's article expresses in an eloquent way the real sense of responsibility he has toward the growth of personality as a function of one of society's oldest institutions. Moreover in his own style he has related the issues involved in psychotherapy to the great historical issues of the ages. Perhaps we can say that his article is a kind of datum as to the impact of social science on his own thinking and his institutional office.     

Callous-Unemotional Traits Modulate Brain Drug Craving Response in High-Risk Young Offenders

Adults with psychopathy have a high propensity for substance abuse, generally starting from a young age. This investigation tested hypotheses about differences in the neural responses associated with drug craving among high-risk young offenders with histories of abuse of stimulants and other drugs as a function of psychopathic traits. Fifty-four male adolescents (44 with a history of stimulant abuse and 10 controls) incarcerated at a maximum-security facility (M age = 17.08 years) completed a drug-cue exposure task while brain hemodynamic activity was monitored using functional magnetic resonance imaging (fMRI) with a mobile MRI scanner stationed at the facility. Psychopathic traits were assessed using the Hare Psychopathy Checklist: Youth Version (PCL:YV). In the stimulant abuser group, drug cues elicited activity in classic reward circuitry. Consistent with studies of adult psychopathic traits and substance abuse, there was a negative association between PCL-YV scores and hemodynamic response related to drug craving in the amygdala and ACC in youth with a history of stimulant abuse. However, there were considerably more negative associations between the PCL:YV and hemodynamic response among youth than adults and this was primarily due to callous-unemotional traits rather than interpersonal or behavioral traits. The implications for how personality traits modulate motivations for drug-seeking behavior among adolescent offenders are discussed.     

Distinct neuronal patterns of positive and negative moral processing in psychopathy

Psychopathy is a disorder characterized by severe and frequent moral violations in multiple domains of life. Numerous studies have shown psychopathy-related limbic brain abnormalities during moral processing; however, these studies only examined negatively valenced moral stimuli. Here, we aimed to replicate prior psychopathy research on negative moral judgments and to extend this work by examining psychopathy-related abnormalities in the processing of controversial moral stimuli and positive moral processing. Incarcerated adult males (N = 245) completed a functional magnetic resonance imaging protocol on a mobile imaging system stationed at the prison. Psychopathy was assessed using the Hare Psychopathy Checklist–Revised (PCL-R). Participants were then shown words describing three types of moral stimuli: wrong (e.g., stealing), not wrong (e.g., charity), and controversial (e.g., euthanasia). Participants rated each stimulus as either wrong or not wrong. PCL-R total scores were correlated with not wrong behavioral responses to wrong moral stimuli, and were inversely related to hemodynamic activity in the anterior cingulate cortex in the contrast of wrong > not wrong. In the controversial > noncontroversial comparison, psychopathy was inversely associated with activity in the temporal parietal junction and dorsolateral prefrontal cortex. These results indicate that psychopathy-related abnormalities are observed during the processing of complex, negative, and positive moral stimuli.     

Aberrant paralimbic gray matter in criminal psychopathy

Psychopaths impose large costs on society, as they are frequently habitual, violent criminals. The pervasive nature of emotional and behavioral symptoms in psychopathy suggests that several associated brain regions may contribute to the disorder. Studies employing a variety of methods have converged on a set of brain regions in paralimbic cortex and limbic areas that appear to be dysfunctional in psychopathy. The present study further tests this hypothesis by investigating structural abnormalities using voxel-based morphometry in a sample of incarcerated men (N=296). Psychopathy was associated with decreased regional gray matter in several paralimbic and limbic areas, including bilateral parahippocampal, amygdala, and hippocampal regions, bilateral temporal pole, posterior cingulate cortex, and orbitofrontal cortex. The consistent identification of paralimbic cortex and limbic structures in psychopathy across diverse methodologies strengthens the interpretation that these regions are crucial for understanding neural dysfunction in psychopathy.     

Paralimbic Gray Matter Reductions in Incarcerated Adolescent Females with Psychopathic Traits

Psychopathy-related paralimbic and limbic structural brain abnormalities have been implicated in incarcerated adult and adolescent male samples. However, there have been few neuroimaging studies of psychopathic traits in females in general and no studies from incarcerated female youth in particular. Here we present the first study to examine the relationship between brain gray matter volumes and psychopathic traits (assessed using the Psychopathy Checklist-Youth Version [PCL-YV]) in a sample of maximum-security incarcerated female adolescents (N?=?39; mean age?=?17.6 years). Consistent with male samples, regional gray matter volumes were negatively related to psychopathic traits in female youth offenders in limbic and paralimbic areas, including orbitofrontal cortex, parahippocampal cortex, temporal poles, and left hippocampus. These results provide evidence that psychopathic traits manifest similar neural abnormalities across sex and age.     

Measurement issues associated with conditional reasoning tests: An examination of faking

Conditional reasoning (CR) is a new item format that measures personality by indirectly assessing reliance upon the cognitive biases associated with specific traits (James et al., 2005). Previous research suggests that, relative to self-report measures, responses on CR-based measures are more difficult to distort (LeBreton, Barksdale, Robin, & James, 2007). The issue of response distortion in the context of CR-based measures was evaluated in two studies. Study 1 (within-subjects) and Study 2 (between-subjects) both investigated whether responses on a CR-based test of addiction could be faked when indirect assessment was upheld. Results of both studies indicated that, unlike a self-report measure of a similar construct, the CR-based measure was unaffected by response distortion.     

Group Reward Contingencies and Cooperative Learning: Immediate and Delayed Effects on Academic Performance,Self-esteem,and Sociometric Ratings

While cooperative learning methods have been reported to have positive effects on a range of personal and social student outcomes, research into their academic benefits has produced mixed results. This study evaluated the effects of one cooperative learning method (cooperative reading and integrated composition, or CIRC) on the reading achievement, sociometric ratings, and self-esteem of 83 third-graders under three reward conditions (group rewards, individual rewards, and no rewards). Although students in the group rewards condition achieved significantly (p < 0.05) higher rate and accuracy scores on weekly reading quizzes than those in the individual and no rewards conditions, this effect was not reflected in overall pre–post reading test scores. There were also no significant effects for condition on the sociometric questionnaire. There was, however, a significant condition by sex interaction effect on total self-esteem scores, which indicated higher scores in the group rewards condition than in the other two conditions for girls. Results are interpreted in light of their practical implications for the application of the CIRC method in school settings, and their theoretical implications for research on the impact of group reward contingencies in cooperative learning methods.

Episodic Life Stress and the Development of Overgeneral Autobiographical Memory to Positive Cues in Youth

Overgeneral autobiographical memory (OGM) has been established as a risk factor for depression in both youth and adults, but questions remain as to how OGM develops. Although theorists have proposed that the experience of stressful life events may contribute to the development of OGM, no studies have examined the impact of negative life events on prospective changes in OGM. The goal of the current study was to address this gap in the literature. Participants included 251 mothers and their biological children (aged 8–14 years old at the initial assessment). Using a multi-wave prospective design with assessments every 6 months for 2 years, we found that episodic life stress predicted prospective decreases in youths’ autobiographical memory specificity to positive, but not negative, cues. This study supports theories proposing that negative life events may contribute to the development of OGM, but suggest that, in youth, the impact of life stress on OGM may be specific to positive rather than negative memories.     

Emerging roles of epigenetic mechanisms in the enduring effects of early-life stress and experience on learning and memory

Epigenetic mechanisms are involved in programming gene expression throughout development. In addition, they are key contributors to the processes by which early-life experience fine-tunes the expression levels of key neuronal genes, governing learning and memory throughout life. Here we describe the long-lasting, bi-directional effects of early-life experience on learning and memory. We discuss how enriched postnatal experience enduringly augments spatial learning, and how chronic early-life stress results in persistent and progressive deficits in the structure and function of hippocampal neurons. The existing and emerging roles of epigenetic mechanisms in these fundamental neuroplasticity phenomena are illustrated.
