Recalled parental bonding,current attachment,and the triarchic conceptualisation of psychopathy

The current investigation examined whether attachment functioning might mediate the effects of parenting on traits associated with psychopathy. Participants completed the Parental Bonding Instrument, the Experiences in Close Relationships Scale, and the Triarchic Psychopathy Measure within a cross-sectional design. Whilst several recalled parenting variables demonstrated significant correlations with the psychopathy subscales, mediation analyses confirmed that the majority of these effects were mediated by current attachment anxiety and avoidance. Only paternal overprotection maintained a significant direct effect on levels of disinhibition. These findings provide support for the argument that attachment dysfunction may represent a potential mechanism through which parenting practices contribute to the emergence of psychopathy-related traits. Inferences regarding causality and mechanisms of effect are naturally constrained by the cross-sectional design of the current investigation, but the preliminary findings presented warrant further examination within prospective designs.     

Executive function as a function of sub-clinical psychopathy

Some aspects of executive function are thought to be dysfunctional in psychopathic individuals. We administered a small battery of neuropsychological tests (spatial alternation task, object alternation task, and Porteus Maze) to two samples of college students and obtained a measure of psychopathy via a self-report questionnaire. Psychopathic traits were related to the tests of object alternation and Porteus Maze but not to the spatial alternation task. Our results support the hypothesis of orbitofrontal cortex (OFC) dysfunction with sparing of dorsolateral prefrontal cortex (DLPFC) in psychopathy and provide a downward extension of this theory to sub-clinical levels of psychopathy.     

Defining the boundary of childhood amnesia

When adults are asked to recall their earliest autobiographical memories most can recall nothing about their infancy and early childhood, a phenomenon commonly referred to as childhood amnesia. There is general consensus regarding the existence of childhood amnesia, but there remains considerable debate over its boundary. Most researchers have argued that the boundary of childhood amnesia occurs between the ages of 3 and 4 years, but in 1993 Usher and Neisser published a highly influential paper, which has subsequently been used to argue that the boundary may be as low as 2 years. In the present experiment we examined how changes in scoring criteria influence our estimates of the age of adults’ earliest memories. We conclude that some coding criteria are more valid than others and that the best estimates of childhood amnesia will include measures of free recall in addition to the specific questions that have dominated prior research in this area.     

Predicting posttraumatic growth among Hurricane Katrina survivors living with HIV: the role of self-efficacy,social support,and PTSD symptoms

Abstract

The study tested the model of adaptation after trauma by Benight and Bandura (2004) indicating that posttraumatic recovery may be predicted directly by coping self-efficacy (CSE) and indirectly by social support. These relations were investigated in the context of posttraumatic growth (PTG) among Hurricane Katrina survivors living with HIV. Additionally, it was hypothesized that among individuals with more intensive Posttraumatic Stress Disorder (PTSD) symptoms, those with strong CSE would experience the strongest PTG. Cross-sectional data were collected among 90 patients with HIV who reinitiated care at the HIV outpatient clinic. Questionnaires were administered approximately 14 months after the hurricane. Higher CSE was related to higher PTG among the survivors who suffered from more intensive PTSD symptoms. Received social support was directly related to only one index of PTG, relating to others. Furthermore, although there was a significant relationship between social support and CSE, the indirect conditional effect of received social support on PTG was not confirmed. Similar results were obtained across the indices of PTG, controlling for the level of exposure to hurricane-related trauma. Cross-sectional design and convenience character of the sample warrants replications.     

Repertory grid in problem structuring: A case illustration

Although the results of previous psychological studies suggested the existence of behavioral freedom, there existed no methodology that could unequivocally identify the portion of human behavior resulting from self-determination or behavioral freedom in human action. The methodological innovations reviewed herein throw a different light on the factors involved in the genesis of human action than was previously possible with extant psychological research methodologies. But critics contend that in such studies subjects might simply be conforming to the experimenter's demands, rather than demonstrating their ability to self-determine. Two studies are presented that demonstrate that conformity is an extremely implausible explanation for the results attributed to self-determination in previous studies. Furthermore, the second study demonstrates the interaction between the idiographically construed meaningfulness of a behavior and one's desire or ability to voluntarily alter that behavior.     

What Sermons Can Tell Us

In this I essay I analyse four sermons delivered at Shan festivals that celebrates the end of the Rains Retreat (Waa). I first argue that sermons in general are important sources of information about lived Buddhism. I next provide background information necessary to understand the sermon events and the sermons. In conclusion, I compare the sermons and discuss what laypeople can learn from sermons and what we, as academics, can learn from them.     

Individualized Challenge Point Practice as a Method to Aid Motor Sequence Learning

We conducted two studies to investigate if and how: (1) the rate of skill acquisition was related to motor performance at retention of a serial RT task (Study 1); and (2) whether rate of skill acquisition and baseline performance could be used to design schedules of practice related to contextual interference (CI) to enhance motor learning (Study 2). In Study 1, a slower rate of skill acquisition of repeating sequences in practice was related to faster response times at retention. Based on performance in Study 1, three levels of individualized CI were created for Study 2. Compared to low and moderate levels of CI, the higher CI practice condition led to faster response times in retention. We conclude that an individualized ‘challenge point’, which generates high CI enhances motor learning by optimizing challenge.     

From Wald to Savage: Homo Economicus Becomes a Bayesian Statistician

Bayesian rationality is the paradigm of rational behavior in neoclassical economics. An economic agent is deemed rational when she maximizes her subjective expected utility and consistently revises her beliefs according to Bayes's rule. The paper raises the question of how, when and why this characterization of rationality came to be endorsed by mainstream economists. Though no definitive answer is provided, it is argued that the question is of great historiographic importance. The story begins with Abraham Wald's behaviorist approach to statistics and culminates with Leonard J. Savage's elaboration of subjective expected utility theory in his 1954 classic The Foundations of Statistics. The latter's acknowledged fiasco to achieve a reinterpretation of traditional inference techniques along subjectivist and behaviorist lines raises the puzzle of how a failed project in statistics could turn into such a big success in economics. Possible answers call into play the emphasis on consistency requirements in neoclassical theory and the impact of the postwar transformation of U.S. business schools.     

Delinquent Peer Group Formation: Evidence of a Gene X Environment Correlation

Emerging evidence suggests that variants of specific genes may influence some youths to seek out or associate with antisocial peers. Using genotypic data (N = 1,816) from the National Longitudinal Study of Adolescent Health (J. R. Udry, 1998, 2003), the authors tested this possibility. They found that the 10R allele of the dopamine transporter (DAT1) gene was associated with self-reported delinquent peer affiliation for male adolescents from high-risk environments (β range = .13-.14) despite controlling for delinquent involvement, self-control, and drug and alcohol use. The authors discuss the importance of using a biosocial framework to examine issues related to adolescent development.
