Mortality salience reduces attentional bias for fear-relevant animals

This research investigated the influence of reminders of mortality on biased attention for fear-relevant animals across 2 studies. In each study, participants completed a baseline dot-probe test of attention to fear-relevant animals (snakes and spiders). After random assignment, participants completed a mortality salience or control writing task (about watching television in Study 1 and about writing an important exam in Study 2). Finally, participants completed the dot-probe measure a second time. In both studies, those in the mortality salience condition showed a significant reduction in bias for fear-relevant animals from baseline to post-manipulation, whereas no change was found for those in the control conditions. These data suggest that the previously demonstrated lack of emotional response to mortality salience may, in part, result from the avoidance of fear-relevant stimuli.

Mythos and Mental Illness: Psychopathy, Fantasy, and Contemporary Moral Life

Medical accounts of the absence of conscience are intriguing for the way they seem disposed to drift away from the ideal of scientific objectivity and towards fictional representations of the subject. I examine here several contemporary accounts of psychopathy by Robert Hare and Paul Babiak. I first note how they locate the truth about their subject in fiction, then go on to contend that their accounts ought to be thought of as a "mythos," for they betray a telling uncertainty about where "fact" ends and "fantasy" begins, as well as the means of distinguishing mental health from mental illness in regard to some social roles.     

Man, I feel like a woman: when and how gender-role motivation helps mind-reading

Two experiments were undertaken with 3 goals: (a) to determine whether manipulating the desirability of including empathy as part of one's gender-role identity motivates accurate mind-reading, (b) to ascertain whether target readability moderates the strength of this effect, and (c) to test whether these effects are mediated by the complexity of perceivers' inferential strategies. Participants viewed videotapes of 2 couples discussing relationship problems and attempted to infer each partner's thoughts and feelings. Both experiments demonstrated that motivation improved accuracy when male and female perceivers valued the empathy-relevant aspects of the traditional female gender role. However, as predicted, high levels of motivation facilitated the accurate reading of easy targets but not of difficult targets. Several mediational models were tested, the results of which showed that the complexity of perceivers' attributions mediated the link between motivation and mind-reading accuracy.     

Solving the $100 modal logic challenge

We present the theoretical foundation, design, and implementation, of a system that automatically determines the subset relation between two given axiomatizations of propositional modal logics. This is an open problem for automated theorem proving. Our system solves all but six out of 121 instances formed from 11 common axiomatizations of seven modal logics. Thus, although the problem is undecidable in general, our approach is empirically successful in practically relevant situations.     

Data on the Conners Teacher Rating Scale from a British clinic population

Conners Teacher Rating Scales were completed on 124 boys aged between 5 and 11 years who attended the child guidance clinics of a large southeast London psychiatric hospital. Comparisons were made with the data provided by Conners (Am. J. Psychiat., 1969,126, 884–888) in which the factor structure of the scale was first identified. This was in response to a reported failure to replicate the scales factor structure in a clinic population despite a number of confirmatory studies on large numbers of children in general populations. Of the scale's five original factors, three were clearly identified. The other two, labeled Hyperactivity and Inattentive-Passive, comprised a single factor. A fifth weaker factor not identified by Conners (1969) was found, consisting principally of antisocial conduct items. The results are seen as providing further evidence of the scales robustness in this, the only other reported clinic study and one in which British children were used for the first time.
