Effects of Photographic Evidence on Mock Juror Judgement1

Effects of three levels of photographic evidence (color, black & white, no photograph) on 144 female subjects' monetary awards to an injured plaintiff were investigated in a 3 × 2 × 3 factorial design. Also manipulated were two levels of the severity of the plaintiff's injury and three levels of defendant blame. As predicted, a significant three-way interaction was observed such that the magnitude of the difference in monetary damages awarded the more and less severely injured plaintiff was greatest in the presence of the color photograph depicting injuries and when defendant blame was high. An emotional arousal interpretation for the effects of photographic evidence is tentatively offered.     

Stability,breadth and guidance

Much recent work on explanation in the interventionist tradition emphasizes the explanatory value of stable causal generalizations—i.e., causal generalizations that remain true in a wide range of background circumstances. We argue that two separate explanatory virtues are lumped together under the heading of `stability’. We call these two virtues breadth and guidance respectively. In our view, these two virtues are importantly distinct, but this fact is neglected or at least under-appreciated in the literature on stability. We argue that an adequate theory of explanatory goodness should recognize breadth and guidance as distinct virtues, as breadth and guidance track different ideals of explanation, satisfy different cognitive and pragmatic ends, and play different theoretical roles in (for example) helping us understand the explanatory value of mechanisms. Thus keeping track of the distinction between these two forms of stability yields a more accurate and perspicuous picture of the role that stability considerations play in explanation.     

Hedonic capacity and schizotypy revisited: a taxometric analysis of social anhedonia

P. E. Meehl (1962) originally conjectured that hedonic capacity was an indicator of the latent class or taxon of schizotypy. However, P. E. Meehl (1989, 1990) subsequently diminished the role of hedonic capacity in his theory, indicating that hypohedonia is one of a dozen normal-range (nontaxonic) individual-differences factors that may potentiate the expression of schizophrenia. This dimensional-only view of hedonic capacity was tested by applying taxometric procedures to the Revised Social Anhedonia Scale (RSAS; M. L. Eckblad, L. J. Chapman, J. P. Chapman, & M. Mishlove, 1982) in a sample of college students (N = 1,526). Analyses indicated that the construct measured by the RSAS is taxonic in nature with a base rate approximating .10. These data are interpreted in the context of other findings suggesting that social anhedonia is an indicator of schizotypy.     

The discriminative validity of a phallometric test for pedophilic interests among adolescent sex offenders against children

The authors examined the responses of adolescent sex offenders against children on a phallometric test of pedophilic interests. Participants were 40 adolescent sex offenders against children, 75 young adult sex offenders against children, and 39 young adult comparison participants. The responses of adolescents with female victims resembled those of comparison participants; adolescents with any male victims had larger relative responses to child stimuli than comparison participants. Young adult offenders, regardless of victim sex, had larger relative responses to child stimuli than comparison participants. Using a cut score of 0 (indicating equal or greater arousal to children than to adults), sensitivity was 42% for adolescents with any male victims, and specificity was 92% for the comparison participants. Results suggest phallometric testing can identify pedophilic interests among these adolescent sex offenders.     

Studies of the vicarious traumatization of college students by the September 11th attacks: effects of proximity, exposure and connectedness

From mid-October 2001 through the end of November 2001, we collected fairly large sets of questionnaires from undergraduates at three public universities (Albany, NY, n = 507, Augusta, GA, n = 336, Fargo, ND, n = 526 ) to assess rate of acute stress disorder (ASD) and level of ASD symptoms following the September 11th attacks, rate of current posttraumatic stress disorder (PTSD) and level of PTSD symptoms, and current level of depressive symptoms resulting from the September 11th attacks. We also gathered information on exposure to media coverage of the attacks, connectedness to the World Trade Center (WTC) and personnel there, and degree of engagement in reparative acts such as giving blood, attending vigils. We found higher levels of ASD, ASD symptoms, PTSD and PTSD symptoms as a function of geographical proximity to New York City (and within the Albany site, proximity of students' homes) and gender. Exposure (hours of TV watched) was a predictor in some instances as was connectedness to WTC victims. ASD symptoms were the strongest predictor of subsequent PTSD symptoms. Path models accounted for over 60% of the variance in PTSD symptoms.     

Posttraumatic stress and depressive symptoms in a college population one year after the September 11 attacks: the effect of proximity

As a follow-up to our earlier report [Behav. Res. Ther., in press] on the level of posttraumatic stress symptoms (PTSS), depressive symptoms, and frequency of diagnoses of probable posttraumatic stress disorder (PTSD) among college students at three public universities (Albany, NY, Augusta, GA, and Fargo, ND) resulting from the September 11, 2001. Terrorist attacks, we surveyed comparable groups of students (total, n = 1313) from these three institutions in the weeks following the first anniversary (2002) of the attacks. We found proximity effects (Albany higher than Augusta which was higher than Fargo) for PTSS and depressive symptoms but not for frequency of diagnoses of probable PTSD. Within the Albany site data, proximity of county of residence to New York City (NYC) also showed a proximity effect on PTSS. Although depressive symptoms were significantly different in 2002 versus 2001, the arithmetic differences in PTSS or in frequency of diagnoses of probable PTSD were not significant. The September 11 attacks continued to exert a psychic toll on college students even a year later.
