Sex-specific clinical correlates of hoarding in obsessive-compulsive disorder

Little is known about whether the clinical correlates of hoarding behavior are different in men and women with obsessive-compulsive disorder (OCD). In the current study, we evaluated the association of hoarding with categories of obsessions and compulsions, psychiatric disorders, personality dimensions, and other clinical characteristics separately in 151 men and 358 women with OCD who were examined during the OCD Collaborative Genetics Study. We found that, among men but not women, hoarding was associated with aggressive, sexual, and religious obsessions and checking compulsions. In men, hoarding was associated with generalized anxiety disorder and tics whereas, among women, hoarding was associated with social phobia, post-traumatic stress disorder, body dysmorphic disorder, nail biting, and skin picking. In women but not men, hoarding was associated with schizotypal and dependent personality disorder dimensions, and with low conscientiousness. These findings indicate that specific clinical correlates of hoarding in OCD are different in men and women and may reflect sex-specific differences in the course, expression, and/or etiology of hoarding behavior in OCD.     

Understanding Public Attitudes Toward Tobacco Harm Reduction: The Role of Attitude Structure1

The present research examines whether and to what extent the underlying structure of attitudes toward harm reduction and specific reduced‐exposure products contributes to an understanding of public attitudes toward harm reduction. Past research has focused on the extent to which some attitude objects are primarily affective or cognitive. Using survey data from a 5‐state Upper Midwest sample, we tested the relevance of 4 pertinent properties of attitudes for predicting overall attitudes toward tobacco harm reduction: affective and cognitive bases of attitudes; knowledge; experience with smoking and reduced‐harm products; and affective/cognitive consistency. We found that feelings about harm reduction are most predictive of overall attitudes toward harm reduction and specific reduced‐harm products. Theoretical and policy implications are discussed.     

Electromyographic evidence of neurological controller signals with viscous load

Ensemble averaging after pre-editing of surface EMG potentials has enabled construction of underlying controller signals from stereotyped head movements. Carefully controlled, intended time-optimal movements by trained, actively participating human subjects have been found to yield repeatable, multi-pulse controller signals. Also, adaptive changes in these horizontal head movements in response to added viscous loads showed further causal relationships between movement dynamics and EMG signals from left and right splenius muscles. These experimental results are a base from which modeling studies can be performed to explicate the neurological control strategies used in the performance of this class of movements.     

Differential effects of red and blue coloured lighting on gambling behaviour

Gambling at a modified version of three-card brag was observed for 28 volunteers, subjected to red or blue light conditions. It is concluded that subjects within a red light environment gambled more money more often and selected riskier odds than did subjects gambling under blue light. Furthermore, riskier bets were generally associated with later trials and red light again enhanced such an effect as compared with blue light. The results are discussed in terms of psychoanalytical theory, psychophysiology and choice shifts within group situations for various gambling activities.

Atheism,faith, and the social scientific study of religion

The social “scientific”; study of religion originated in atheism and the basic theses pursued today, especially by psychologists and anthropologists, are little changed since they were first proposed by militant opponents of religion in the seventeenth and early eighteenth century. In this essay I trace these links from major scholar to major scholar across the centuries. I then examine the remarkable irony that the recent emergence of a truly scientific approach to religion was accomplished mainly by an influx of “believers”;. I sketch why and how this happened before turning to an assessment of the persistence of atheistic biases. I conclude with suggestions about how a truly scientific study of religion can be pursued by both believers and unbelievers, if not by fanatics of either stripe.
