Re-introduction to cross-cultural studies of the EPQ

Cross-cultural projects were undertaken, over some 25 years, to standardise the EPQ (both Adult and Junior forms) for many countries (See Appendix B for a list).     

Discrete Emotions or Dimensions? The Role of Valence Focus and Arousal Focus

The present study provides evidence that valence focus and arousal focus are important processes in determining whether a dimensional or a discrete emotion model best captures how people label their affective states. Individuals high in valence focus and low in arousal focus fit a dimensional model better in that they reported more co-occurrences among like-valenced affective states, whereas those lower in valence focus and higher in arousal focus fit a discrete model better in that they reported fewer co-occurrences between like-valenced affective states. Taken together, these findings suggest that one static, nomothetic theory may not accurately describe the subjective affective experience of all individuals.     

Bridging developmental systems theory and evolutionary psychology using dynamic optimization

Interactions between evolutionary psychologists and developmental systems theorists have been largely antagonistic. This is unfortunate because potential synergies between the two approaches remain unexplored. This article presents a method that may help to bridge the divide, and that has proven fruitful in biology: dynamic optimization. Dynamic optimization integrates developmental systems theorists’ focus on dynamics and contingency with the ‘design stance’ of evolutionary psychology. It provides a theoretical framework as well as a set of tools for exploring the properties of developmental systems that natural selection might favor, given particular evolutionary ecologies. We also discuss limitations of the approach.     

Errors and Understanding: The Effects of Error-Management Training on Creative Problem-Solving

People make errors in their creative problem-solving efforts. The intent of this article was to assess whether error-management training would improve performance on creative problem-solving tasks. Undergraduates were asked to solve an educational leadership problem known to call for creative thought where problem solutions were scored for quality, originality, and elegance. Prior to beginning work on their problem solutions, participants were provided with training in 0 to 4 error-management strategies. It was found that error-management training was beneficial for talented people (as indicated by scores on the pretraining exercise) resulting in solutions of greater originality. The implications of these findings for improving performance on creative problem-solving tasks are discussed.     

Investigating Hypervigilance for Social Threat of Lonely Children

The hypothesis that lonely children show hypervigilance for social threat was examined in a series of three studies that employed different methods including advanced eye-tracking technology. Hypervigilance for social threat was operationalized as hostility to ambiguously motivated social exclusion in a variation of the hostile attribution paradigm (Study 1), scores on the Children’s Rejection-Sensitivity Questionnaire (Study 2), and visual attention to socially rejecting stimuli (Study 3). The participants were 185 children (11 years-7 months to 12 years-6 months), 248 children (9 years-4 months to 11 years-8 months) and 140 children (8 years-10 months to 12 years-10 months) in the three studies, respectively. Regression analyses showed that, with depressive symptoms covaried, there were quadratic relations between loneliness and these different measures of hypervigilance to social threat. As hypothesized, only children in the upper range of loneliness demonstrated elevated hostility to ambiguously motivated social exclusion, higher scores on the rejection sensitivity questionnaire, and disengagement difficulties when viewing socially rejecting stimuli. We found that very lonely children are hypersensitive to social threat.     

The ROC Toolbox: A toolbox for analyzing receiver-operating characteristics derived from confidence ratings

Signal-detection theory, and the analysis of receiver-operating characteristics (ROCs), has played a critical role in the development of theories of episodic memory and perception. The purpose of the current paper is to present the ROC Toolbox. This toolbox is a set of functions written in the Matlab programming language that can be used to fit various common signal detection models to ROC data obtained from confidence rating experiments. The goals for developing the ROC Toolbox were to create a tool (1) that is easy to use and easy for researchers to implement with their own data, (2) that can flexibly define models based on varying study parameters, such as the number of response options (e.g., confidence ratings) and experimental conditions, and (3) that provides optimal routines (e.g., Maximum Likelihood estimation) to obtain parameter estimates and numerous goodness-of-fit measures.The ROC toolbox allows for various different confidence scales and currently includes the models commonly used in recognition memory and perception: (1) the unequal variance signal detection (UVSD) model, (2) the dual process signal detection (DPSD) model, and (3) the mixture signal detection (MSD) model. For each model fit to a given data set the ROC toolbox plots summary information about the best fitting model parameters and various goodness-of-fit measures. Here, we present an overview of the ROC Toolbox, illustrate how it can be used to input and analyse real data, and finish with a brief discussion on features that can be added to the toolbox.     

Reply to Doody

In an earlier paper, we appealed to various empirical studies to make the case that the unconscious mind is capable of robust self-deception. Paul Doody has challenged our interpretations of that empirical evidence. In this reply we defend our interpretations, arguing that the unconscious is engaged in strategic and flexible goal pursuit.     

Behavioral interventions may prolong remission in patients with inflammatory bowel disease

Inflammatory Bowel Diseases (IBDs) are chronic, relapsing and remitting gastrointestinal conditions with no known cure. Previous studies have linked behavioral factors, including stress and medication adherence, to relapse.

Purpose

We sought to determine the effect of participation in a behavioral self-management program on incidence of flare within 12 months following behavioral intervention when compared to the natural history of flare incidence prior to program participation.

Results

Results from a 2-level regression model indicated that those participants in the treatment group were 57% less likely to flare in the following 12 months (compared to 18% in the control group). The decline in “flare odds” was about 2 times greater in treatment versus controls (OR = 0.52, t(34) = 2.07, p < 0.05). Office visits, ER visits, and disease severity (all p < 0.05) were identified as moderators of flare risk.

Conclusions

We have demonstrated 1) a statistical model estimating the likelihood of flare rates in the 12 months following a behavioral intervention for IBD (compared to a control condition), and 2) that the introduction of a behavioral intervention can alter the natural course of a chronic, relapsing and remitting gastrointestinal condition such as IBD.     

Cognitive Science of Religion: Looking Back,Looking Forward

The cognitive science of religion (CSR) arose out of attempts to “science up” religious studies and the anthropology of religion without eliminating interpretive approaches. While maintaining this historical orientation, CSR holds promise to help bridge to other areas within the scientific study of religion. Particularly fruitful areas of future collaboration and complementary study are evolutionary studies of religion, psychology of religion, sociology of religion, and archeology of religion. In response to an invitation to explore the potential of CSR for the 50th anniversary of this journal, I briefly summarize CSR's history and current state and then offer exemplary future directions that might bring CSR into fruitful connection with other areas in the greater scientific study of religion.     

British men's hair color preferences: an assessment of courtship solicitation and stimulus ratings

Two studies examined the influence of women's hair color on approach behavior by British men and on ratings of physical attractiveness and personality. In Study 1, a female confederate whose hair color was dyed blonde, brunette, or red was instructed to sit in several nightclubs. It was found that she was approached significantly more frequently by men in the blonde condition. In Study 2, images of the same confederate were rated by 126 men. Results showed that the brunette stimulus was rated as more physically attractive, intelligent, approachable, competent, and arrogant, whereas the blonde stimulus was rated as more needy. These results are discussed in relation to the literature on hair color and attractiveness, but also in terms of women's own perceptions of their hair color.
