Convergent validity of the Youth Psychopathic Traits Inventory (YPI): association with the Psychopathy Checklist: Youth Version (PCL:YV)

This study investigates the relationship between the self-report Youth Psychopathic Traits Inventory (YPI) and the clinician-rated Psychopathy Checklist: Youth Version (PCL:YV). A representative sample of 92 girls and 70 boys, 12 to 20 years of age (mean age, 17 years), who received services at a clinic for adolescents with substance misuse problems, was studied. Moderate correlations (r =.30-.51) were found between conceptually corresponding YPI and PCL:YV factor scores among both boys and girls, whereas correlations between individual subscales of the YPI and items of the PCL:YV were not as consistent. A cross-tabulation of groupings based on the three-factor models of the two instruments largely supported the categorical convergent validity of the YPI, particularly for low and high scorers. Although more studies with larger samples are needed, results indicate that the YPI is a cost-effective measure of psychopathic traits in adolescents in research settings.     

Capturing naturally occurring superior performance in the laboratory: translational research on expert performance

One of the central challenges to studying highly skilled performance in the laboratory is methodological. It is necessary to develop standardized methods that allow investigators to make experts repeatedly reproduce their superior performance in the laboratory. The recent increase in demand for translational research has raised related issues of how everyday phenomena, such as successful clinical treatments and expert achievement, can be reproduced in the laboratory and how laboratory studies of these phenomena can lead to successful interventions in everyday life. The expert-performance approach was developed as a framework for capturing, analyzing, and accounting for complex acquired skills and adaptations. Performance is initially captured and elicited in the laboratory using tasks representative of core activities in the domain. Process-tracing measures are employed to identify the mechanisms that mediate the reproducibly superior performance. Finally, the factors responsible for the development of the mediating mechanisms are studied by a retrospective analysis of training activities, such as deliberate practice, as well as genetic prerequisites. The principles and mechanisms discovered need then be validated using more traditional longitudinal and experimental designs.     

Cognitive Enhancement: Methods, Ethics, Regulatory Challenges

Cognitive enhancement takes many and diverse forms. Various methods of cognitive enhancement have implications for the near future. At the same time, these technologies raise a range of ethical issues. For example, they interact with notions of authenticity, the good life, and the role of medicine in our lives. Present and anticipated methods for cognitive enhancement also create challenges for public policy and regulation.     

Non-transitive Better than Relations and Rational Choice

Philosophia - This paper argues that decision problems and money-pump arguments should not be a deciding factor against accepting non-transitive better than relations. If the reasons to accept...
