Individual differences in impulsive choice and timing in rats

Individual differences in impulsive choice behavior have been linked to a variety of behavioral problems including substance abuse, smoking, gambling, and poor financial decision-making. Given the potential importance of individual differences in impulsive choice as a predictor of behavioral problems, the present study sought to measure the extent of individual differences in a normal sample of hooded Lister rats. Three experiments utilized variations of a delay discounting task to measure the degree of variation in impulsive choice behavior across individual rats. The individual differences accounted for 22-55% of the variance in choice behavior across the three experiments. In Experiments 2 and 3, the individual differences were still apparent when behavior was measured across multiple choice points. Large individual differences in the rate of responding, and modest individual differences in timing of responding were also observed during occasional peak trials. The individual differences in timing and rate, however, did not correlate consistently with individual differences in choice behavior. This suggests that a variety of factors may affect choice behavior, response rate, and response timing.     

Individual differences in face identification postdict eyewitness accuracy

Eyewitnesses frequently mistake innocent suspects for the culprits of an observed crime, and such misidentifications have caused the wrongful convictions of many innocent people. This study attempted to establish the accuracy of individual eyewitnesses by assessing their ability to process unfamiliar faces. Observers viewed a staged crime and later tried to select the culprit from an identity lineup. This was followed by a face test that provides a laboratory analogue to lineup identifications. We found that this face test could determine the reliability of individual witnesses when a positive eyewitness identification had been made. Importantly, this was possible based on the specific response that a witness had made and without prior knowledge of whether the culprit was actually present in the lineup. These findings demonstrate that individual differences in face processing provide a potential instrument for postdicting eyewitness accuracy and for preventing miscarriages of justice.     

Psychopathic personality traits in the workplace: Implications for interpersonally- and organizationally-directed counterproductive and citizenship behaviors

Relatively little is known about the relations between psychopathic traits and interpersonally-directed versus organizationally-directed workplace behaviors despite the implications of these traits for maladaptive (e.g., bullying, harassing, white-collar crime, slacking) and adaptive (e.g., improving the workplace, supporting others) workplace behaviors. In a sample of employed US-based community members (N?=?352), we investigated the relations between the Triarchic Psychopathy Measure (TriPM) and an expanded version of the Levenson Self-Report Psychopathy Scale (E-LSRP), on the one hand, and interpersonal and organizational counterproductive behaviors and citizenship behaviors directed towards co-workers and the organization, on the other. As predicted, we found stronger positive associations between impulsive-antisocial traits (Disinhibition, Antisocial) and both interpersonal and organizational workplace deviance; however, these traits did not relate significantly to citizenship behaviors. We further found that interpersonal traits (Boldness, Egocentric) may play an adaptive role in the workplace, as demonstrated by increased citizenship behaviors. Affective traits (Callous, Meanness) were related to lesser engagement in citizenship behaviors and higher engagement in some interpersonally-directed counterproductive behaviors. In several analyses, statistical interactions among triarchic psychopathy traits, but not E-LSRP traits, predicted adaptive and maladaptive workplace behaviors. Our results suggest that employees’ psychopathic traits bear differential implications for both adaptive and maladaptive workplace behavior, and that these traits may operate in concert to increase the likelihood of such behavior.

     

The Pew Versus the Couch: Relationship Between Mental Health and Faith Communities and Lessons Learned from a VA/Clergy Partnership Project

The history of the relationship between religion and mental health is one of commonality, conflict, controversy, and distrust. An awareness of this complex relationship is essential to clinicians and clergy seeking to holistically meet the needs of people in our clinics, our churches, and our communities. Understanding this relationship may be particularly important in rural communities. This paper briefly discusses the history of this relationship and important areas of disagreement and contention. The paper moves beyond theory to present some current practical tensions identified in a brief case study of VA/Clergy partnerships in rural Arkansas. The paper concludes with a framework of three models for understanding how most faith communities perceive mental health and suggests opportunities to overcome the tensions between “the pew” and “the couch.”     

The Role of Hofstede's Individualism in National-Level Creativity

It is a widely held belief that culture is a factor that influences creativity. The influence of culture on creativity is, however, relatively understudied and the majority of creativity research focuses on creativity at the level of the individual or organization. In this article, the relationship between Hofstede's cultural values (individualism, power distance and uncertainty avoidance) and national level scores on two separate creativity indexes—the Global Creativity Index (GCI) and the Design and Creativity Index (DCI) was examined. A multivariate multiple linear regression analyses showed a strong positive relationship between individualism and national ranking on the GCI and DCI. No significant relationship was found between the creativity measures and Hofstede's power distance and uncertainty avoidance. The positive relationship between individualism and creativity suggests that autonomy, independence, and freedom—beliefs associated with individualism—are needed for a nation to be creative.     

Music for the Seasons: Seasonal Music Preferences in College Students

The present research examined music preferences in relation to the seasons: fall, winter, spring, and summer. Across two studies, male and female college students (N = 232 and 199) were primed to think about the seasons and indicate their music preference from Rentfrow and Gosling’s (2003) music classification scheme. Participants were predicted to prefer reflexive and complex music when primed with fall/winter and energetic and rhythmic and upbeat and conventional music when primed with spring/summer. Study 1 had participants read winter or summer season scenarios and Study 2 had participants write their own fall, winter, spring, or summer seasonal experiences. Overall, results were consistent with predictions for the reflexive and complex and energetic and rhythmic classifications, indicating an environmental influence of musical preferences.
