Disturbed prefrontal and temporal brain function during emotion and cognition interaction in criminal psychopathy

Impaired emotional responsiveness has been revealed as a hallmark of psychopathy. In spite of an increasing database on emotion processing, studies on cognitive function and in particular on the impact of emotion on cognition in psychopathy are rare. We used pictures from the International Affective Picture Set (IAPS) and a Simon Paradigm to address emotion-cognition interaction while functional and structural imaging data were obtained in 12 healthy controls and 10 psychopaths. We found an impaired emotion-cognition interaction in psychopaths that correlated with a changed prefrontal and temporal brain activation. With regard to the temporal cortex, it is shown that structure and function of the right superior temporal gyrus is disturbed in psychopathy, supporting a neurobiological approach to psychopathy, in which structure and function of the right STG may be important.     

How do personality disorders modify suicide risk?

There is a lack of psychological autopsy studies assessing the influence of axis II disorders on other risk factors for suicide. Therefore, we investigated if the estimated suicide risk for axis I disorders and socio-demographic factors was modified by personality disorders. Psychiatric disorders were evaluated by a semi-structured interview including the Structured Clinical Interview for DSM-IV Axis I (SCID-I) and Personality Disorders (SCID-II) by psychological autopsy method in 163 completed suicides and by personal interview in 396 population-based control persons. Personality disorders modify suicide risk, differently for affective disorders, substance use disorders, smoking, life events during the last three months, and socio-demographic factors such as being single. Estimated suicide risk for socio-demographic factors and life events is not substantially altered following adjustment for affective disorders or substance use disorders. These findings suggest that treatment of personality disorders is essential for suicide prevention.     

De-Ontologizing the Debate on Social Explanations: A Pragmatic Approach Based on Epistemic Interests

In a recent paper on realism and pragmatism published in this journal, Osmo Kivinen and Tero Piiroinen have been pleading for more methodological work in the philosophy of the social sciences—refining the conceptual tools of social scientists—and less philosophically ontological theories. Following this de-ontologizing approach, we scrutinize the debates on social explanation and contribute to the development of a pragmatic social science methodology. Analyzing four classic debates concerning explanation in the social sciences, we propose to shift the debate away from (a) the ontologizing defenses of forms of social explanation, and (b) a winner-takes-all-approach. Instead, we advocate (c) a pragmatic approach towards social explanation, elaborating a rigorous framework for explanatory pluralism detached from the debates on social ontology.

Multiple confidence estimates as indices of eyewitness memory

Eyewitness identification decisions are vulnerable to various influences on witnesses' decision criteria that contribute to false identifications of innocent suspects and failures to choose perpetrators. An alternative procedure using confidence estimates to assess the degree of match between novel and previously viewed faces was investigated. Classification algorithms were applied to participants' confidence data to determine when a confidence value or pattern of confidence values indicated a positive response. Experiment 1 compared confidence group classification accuracy with a binary decision control group's accuracy on a standard old-new face recognition task and found superior accuracy for the confidence group for target-absent trials but not for target-present trials. Experiment 2 used a face mini-lineup task and found reduced target-present accuracy offset by large gains in target-absent accuracy. Using a standard lineup paradigm, Experiments 3 and 4 also found improved classification accuracy for target-absent lineups and, with a more sophisticated algorithm, for target-present lineups. This demonstrates the accessibility of evidence for recognition memory decisions and points to a more sensitive index of memory quality than is afforded by binary decisions.     

Eyewitness recall: Regulation of grain size and the role of confidence

Eyewitness testimony plays a critical role in Western legal systems. Three experiments extended M. Goldsmith, A. Koriat, and A. Weinberg-Eliezer's (2002) framework of the regulation of grain size (precision vs. coarseness) of memory reports to eyewitness memory. In 2 experiments, the grain size of responses had a large impact on memory accuracy. Further, participants achieved a compromise between the accuracy and informativeness of their testimony by volunteering precise answers only when likely to be correct. The level of detail reported was strongly, positively related to confidence in the accuracy of the response. This highlights the importance of considering the level of detail, not just the accuracy, of eyewitness testimony.     

Examining career-related mentoring and managerial performance across cultures: A multilevel analysis

The benefits of the mentoring relationship for protégés have been a primary focus in the mentoring literature. Researchers have recently begun to examine how mentoring can benefit the mentor. The purpose of the present study is to examine whether direct report-ratings of a manager’s career-related mentoring behaviors are related to boss-ratings of that manager’s performance. In addition, this study assesses whether the cultural background of the manager moderates the career-related mentoring-performance relationship via multilevel methodology. Results reveal that managers who are rated by their direct reports as engaging in career-related mentoring behaviors are perceived as better performers by their bosses. Moreover, the GLOBE societal culture dimension of Performance Orientation was a significant cross-level moderator of the career-related mentoring-performance relationship. Implications for the practice of mentoring in cross-cultural contexts across multiple disciplines are discussed.     

Abandoning the Public Good: How Universities Have Helped Privatize Higher Education

In this article we assert that much of the public good associated with teaching and research in higher education is gradually being displaced. This privatization of higher education is reflected in increased licensing of research and in the fragmentation of the traditional general education core. Taxpayer de-funding and institutional substitution are economic consequences of public good displacement.     

Cognitive Neuropsychology of HIV-Associated Neurocognitive Disorders

Advances in the treatment of the human immunodeficiency virus (HIV) have dramatically improved survival rates over the past 10 years, but HIV-associated neurocognitive disorders (HAND) remain highly prevalent and continue to represent a significant public health problem. This review provides an update on the nature, extent, and diagnosis of HAND. Particular emphasis is placed on critically evaluating research within the realm of cognitive neuropsychology that aims to elucidate the component processes of HAND across the domains of executive functions, motor skills, speeded information processing, episodic memory, attention/working memory, language, and visuoperception. In addition to clarifying the cognitive mechanisms of HAND (e.g., impaired cognitive control), the cognitive neuropsychology approach may enhance the ecological validity of neuroAIDS research and inform the development of much needed novel, targeted cognitive and behavioral therapies. The research described was supported by MH73419 and MH62512 from the National Institutes of Health.

Gendered Ways to Motivation Gains in Groups

Recent studies have demonstrated motivation gains of low performing group members even beyond the level of an individual work baseline (e.g., Weber and Hertel, Journal of Personality and Social Psychology, 93:973–993, 2007). We expected that the underlying mechanisms of these motivation gains, i.e., social indispensability and social competition, are moderated by individuals’ gender. Moreover, these gender effects were assumed to be moderated by partner anonymity. Predictions were tested with mostly undergraduate German students (N?=?213) working in same-gender groups in a computer-supported environment. Results revealed that motivation gains due to social indispensability were more likely for women, whereas motivation gains due to social competition were more likely for men. Furthermore, women compared to men showed higher motivation gains in anonymous conditions compared to conditions with an acquainted partner.     

Emergence of Life

Discussions of the origin of life usually assume that there is a specific event, however improbable, by which dead matter became a living entity. Naturalistic accounts, although in seeming opposition to theistic explanations of the apparent design of even the simplest cells, often share the assumption that there is a specific line to be crossed. If the problem is recast as one of a process of emergence of biochemistry from protobiochemistry, which in turn emerged from the organic chemistry and geochemistry of primitive earth, the resources of the new sciences of complex systems dynamics can provide a more robust conceptual framework within which to explore the possible pathways of chemical complexification leading to life. In such a view the emergence of life is the result of deep natural laws (the outlines of which we are only beginning to perceive) and reflects a degree of holism in those systems that led to life. Further, there is the possibility of developing a more general theory of biology and of natural organization from such an approach. The emergence of life may thus be seen as an instance of the broader innate creativity of nature and consistent with a possible natural teleology.
