On some limits of hypothetical thinking

Faced with extreme demands, hypothetical thinking runs the danger of total failure. Paradoxical propositions such as the Liar (“I am lying”) provide an opportunity to test it to its limits, while the Liar's nonparadoxical counterpart, the Truthteller (“I am telling the truth”), provides a useful comparison. Two experiments are reported, one with abstract materials (“If I am a knave then I live in Emerald City”) and one with belief-laden materials (a judge says: “If I am a knave then I enjoy pop music”). In both experiments, conditionals with Truthteller-type antecedents were “collapsed” to responses of conditional probability closely resembling estimates of control items. Liar-type antecedents, in contrast, dramatically weakened belief in conditionals in which they were embedded. The results are discussed in the framework of the theory of hypothetical thinking.     

Moderators of Social Power Use for In‐Group/Out‐Group Targets: An Experimental Paradigm1

Studies of social power use have frequently employed self‐report instruments that are prone to response bias. In the present study, an experimental design was conducted in which 100 participants were asked to gain compliance from in‐group and out‐group members. We tested whether harsh tactics—often used for elevating self‐image at the dyadic level—also provide a means for gaining advantage at the group level. For this purpose, self‐esteem and self‐efficacy were examined as possible moderators. Findings indicated that self‐esteem interacted with target group: Low self‐esteem participants used harsh tactics more frequently toward in‐group than out‐group members; and moderate and high self‐esteem participants used harsh tactics more frequently toward out‐group than in‐group members. The process involved in this interaction is discussed.     

A friend is a present you give to your “Self”: Avoidance of intimacy moderates the effects of friends on self-liking

The current research proposes that thinking about friends improves feelings about the self and does so differentially depending on avoidance of intimacy. Based on previous findings that individuals who avoid intimacy in relationships (avoidant individuals) contrast their self-concepts with primed friends whereas those who pursue intimacy in relationships (non-avoidant individuals) assimilate their self-concepts to primed friends [Gabriel, S., Carvallo, M., Dean, K., Tippin, B. D., & Renaud, J. (2005). How I see “Me” depends on how I see “We”: The role of avoidance of intimacy in social comparison. Personality and Social Psychology Bulletin, 31, 156-157], we predicted that friends who embody negative aspects of self would lead avoidant individuals to like themselves more, whereas friends who embody positive aspects of self would lead non-avoidant individuals to like themselves more. A pretest determined that good friends were seen as more similar to positive and ideal aspects of the self, whereas friends about whom participants had more mixed feelings (ambivalent friends) were seen as more similar to disliked and feared aspects of the self. Four experiments supported the main hypotheses. In Experiment 1, non-avoidant individuals like themselves more when good friends were primed. In Experiment 2, avoidant individuals like themselves more when ambivalent friends were primed. In Experiment 3, non-avoidant individuals liked themselves better after thinking about a friend’s positive traits, whereas avoidant individuals liked themselves better after thinking about a friend’s negative traits. In Experiment 4, all individuals under self-esteem threat strategically brought friends to mind who would help them like themselves more.     

Rabbis and Health: A Half-Century Review of the Mental and Physical Health Care Literature:1950–1999

Electronic searches were conducted on PubMed and the American Psychological Association's database (PsycINFO) for articles that discussed the role of rabbis in relation to some aspect of healthcare. The two searches were conducted in each electronic database using the search-terms: (1) (rabbi OR rabbinical OR synagogue) OR (2) (Judaism OR Jewish) AND (clergy OR chaplain). Articles were classified by the year of their publication, professional discipline, type of journal (either religious or secular), and type of article: either research, or narrative and expositional. Rabbis were discussed most often in psychology, psychiatry, and behavior-related fields, and close to two-thirds of the articles dealt with mental health concerns. A statistically significant increase in articles across decades was found in the secular journals, r=.98, p≤.01, with over 70% of the articles about rabbis in the secular journals being published between 1980 and 1999. Many of the articles addressed collaboration between rabbis, psychiatrists, and other and mental health professionals and discussed previously identified themes related to professional collaboration and referral.     

Terrorism Between "Syndrome" and "Tool"

ABSTRACT— Two psychological views of terrorism are described, approaching it as a "syndrome" and as a "tool" respectively. Research thus far found little support for the syndrome view. The heterogeneity of terrorism's users is consistent with the tool view, affording an analysis of terrorism in terms of goal–means psychology.     

Predictors of Morale in U.S. Peacekeepers1

In this prospective study, we examined pre‐ and postmission predictors of morale in U.S. military peacekeepers deployed to Kosovo. After controlling for demographic and military characteristics, current general life stressors, unit cohesion, and reports of patriotism and nationalism were predictive of predeployment morale. We also found that positive military experiences, general overseas military stressors, and postdeployment unit cohesion were significant predictors of postdeployment morale after controlling for demographic and military characteristics and predeployment morale, cohesion, and patriotism/nationalism. The results suggest the need to broaden our understanding of the factors that may assist and motivate soldiers during demanding peacekeeping operations and the factors that may mitigate the impact of stressful demands and associated mission‐related strain.     

Understanding the relationship between posttraumatic stress disorder and trauma cognitions: The impact of thought control strategies

Several models of PTSD suggest that dysfunctional beliefs play an important role in the maintenance of PTSD. This study examined whether thought control strategies intermediated in the relationship between PTSD and dysfunctional cognitions. It was hypothesized that PTSD would be positively associated with dysfunctional cognitions and that negative thought control strategies (worry and self-punishment) would partially account for this relationship. These maladaptive strategies were predicted to be associated with increased levels of PTSD and more trauma-related beliefs. Additionally, it was predicted that positive thought control strategies (social control and reappraisal) would be associated with decreased levels of PTSD and fewer trauma-related beliefs. Finally, because the literature supports distraction as both an adaptive and a maladaptive thought control strategy, no a priori hypothesis was made. Results support worry and self-punishment as maladaptive intervening variables in the association between PTSD and dysfunctional cognitions, resulting in greater levels of PTSD and trauma cognitions. Social control and distraction emerged as adaptive strategies, resulting in lower levels of PTSD and trauma cognitions, while reappraisal showed no relationship with PTSD severity. Although the results are cross-sectional, continued focus on the effects of thought control strategies as meditational maintenance variables over time appears warranted.     

The Coming-Out Process and Its Adaptational and Health-Related Associations Among Gay, Lesbian, and Bisexual Youths: Stipulation and Exploration of a Model

A model is proposed and explored that links the coming-out process to the psychological functioning (i.e., self-esteem and distress) and sexual behaviors of gay, lesbian, and bisexual youths recruited from gay-focused community-based and college organizations in New York City. The coming-out process is multidimensional, consisting, as defined here, of involvement in gay/lesbian activities, attitudes toward homosexuality, comfort with homosexuality, self-disclosure of sexual identity to others, and sexual identity. The coming-out dimensions were related to self-esteem, distress, and unprotected sexual behaviors. In addition, the relations between the coming-out dimensions and unprotected sexual behaviors were explained by psychological functioning. In particular, limited involvement in gay/lesbian activities was associated with more unprotected sex. Negative attitudes toward homosexuality were related directly to more unprotected sex, and they were related indirectly to more unprotected sex by means of increasing emotional distress. These and other findings have implications for designing preventive interventions to increase the youths' psychological functioning and reduce their unprotected sexual behaviors.     

Antialiasing: A technique for smoothing jagged lines on a computer graphics image—an implementation on the Amiga

Images displayed on computer graphics displays often suffer from the presence of aliasing artifacts that give a jagged appearance to lines or polygon edges displayed on the screen. This paper details the problems associated with these artifacts and presents a method for drawingantialiased lines—ones in which the artifacts have been considerably reduced. The line-drawing routine is further developed to incorporategamma correction, to take into account the nonlinear relationship between the intensity of the light emission from the phosphor of the monitor and the grayscale values used to control the intensity on the screen.
