Perceived Risk of AIDS: Assessing the Behavioral and Psychosocial Consequences in a Cohort of Gay Men1

Longitudinal analyses reported here explored the relationship between a perceived sense of being at risk for AIDS and a variety of behavioral, social, and psychological consequences. Data were obtained from a cohort of 637 homosexual men living in Chicago, who are participating in a psychosocial study and have completed two waves of data collection. Their perceptions of risk were quantified using both an absolute and a comparative measure; these were combined into a risk index, scored from one to nine (x?= 3.91; SD= 1.64). Univariate analyses demonstrated that level of risk was related to several measures of subsequent behavioral risk reduction. However, after adjustment for sociodemographic variables, initial behavior, and other components of a model predicting behavior change, this was no longer true. Of the 12 behavioral outcomes assessed, only one was related to risk after appropriate adjustment, and this relationship was negative. Other longitudinal analyses examined the impact of a sense of risk on measures of psychosocial functioning which have been theoretically linked to health behaviors and to measures of psychological/ social distress. These demonstrated a range of potentially adverse consequences for those who perceived themselves to be at greater risk for AIDS, including increased barriers to behavioral change, obsessive/compulsive behavior, social role impairment, and more intrusive worries and concerns about AIDS. Taken together, these results suggest that there is little or no observable benefit to an increased sense of risk, but that such a sense subsequently leads to distress and dysfunction in a variety of realms. The implications of these findings for development of policy concerning antibody testing of at-risk populations is discussed.     

The Influence of Episodic and Thematic Frames on Policy and Group Attitudes: Mediational Analysis

An experiment examined how episodic and thematic political message frames affect attitudes toward older adults and Social Security. When exposed to messages about abolishing Social Security, participants exposed to episodic frames were significantly more likely to endorse message‐consistent attitudes than participants exposed to a thematic frame. In mediation analyses, an episodic frame featuring a counterstereotypical exemplar increased endorsement of individual responsibility for retirement planning, which then led to more negative attitudes toward Social Security. These effects did not occur with a stereotypical exemplar in an episodic frame. The same mediated pathway influenced attitudes toward older adults in a more complex manner. Results provide support for individual responsibility attributions as a mediating mechanism underlying the effects of certain episodic frames.     

Testing a model of minority identity achievement, identity affirmation, and psychological well-being among ethnic minority and sexual minority individuals

How is social identity related to psychological well-being among minority individuals? Drawing on developmental models of identity formation (e.g., Erikson, 1968) and on Social Identity Theory (Tajfel & Turner, 1979), we tested a conceptual model examining links between two key aspects of social identity and psychological well-being. We proposed that the association between identity achievement (exploring and understanding the meaning of one's identity) and psychological well-being is mediated by identity affirmation (developing positive feelings and a sense of belonging to one's social group). Across three studies, including ethnic minority high school students (Study 1), ethnic minority college students (Study 2) and lesbian and gay male adults (Study 3), we found strong support for the model. Results suggest that the process of exploring and understanding one's minority identity can serve as an important basis for developing positive feelings toward and an enhanced sense of attachment to the group, which can in turn confer psychological benefits for minority individuals. Implications and directions for future research are discussed.     

Constitutional Moments in Governing Science and Technology

Scholars in science and technology studies (STS) have recently been called upon to advise governments on the design of procedures for public engagement. Any such instrumental function should be carried out consistently with STS’s interpretive and normative obligations as a social science discipline. This article illustrates how such threefold integration can be achieved by reviewing current US participatory politics against a 70-year backdrop of tacit constitutional developments in governing science and technology. Two broad cycles of constitutional adjustment are discerned: the first enlarging the scope of state action as well as public participation, with liberalized rules of access and sympathetic judicial review; the second cutting back on the role of the state, fostering the rise of an academic-industrial complex for technology transfer, and privatizing value debates through increasing delegation to professional ethicists. New rules for public engagement in the United Sates should take account of these historical developments and seek to counteract some of the anti-democratic tendencies observable in recent decades.     

Young infants' generalization of emotional expressions: effects of familiarity

From birth, infants are exposed to a wealth of emotional information in their interactions. Much research has been done to investigate the development of emotion perception, and factors influencing that development. The current study investigates the role of familiarity on 3.5-month-old infants' generalization of emotional expressions. Infants were assigned to one of two habituation sequences: in one sequence, infants were visually habituated to parental expressions of happy or sad. At test, infants viewed either a continuation of the habituation sequence, their mother depicting a novel expression, an unfamiliar female depicting the habituated expression, or an unfamiliar female depicting a novel expression. In the second sequence, a new sample of infants was matched to the infants in the first sequence. These infants viewed the same habituation and test sequences, but the actors were unfamiliar to them. Only those infants who viewed their own mothers and fathers during the habituation sequence increased looking. They dishabituated looking to maternal novel expressions, the unfamiliar female's novel expression, and the unfamiliar female depicting the habituated expression, especially when sad parental expressions were followed by an expression change to happy or to a change in person. Infants are guided in their recognition of emotional expressions by the familiarity of their parents, before generalizing to others.     

Event-based prospective memory for poorly attended events

In the most frequently used paradigm for studying event-based prospective memory (PM, Einstein & McDaniel, 1990), participants perform an ongoing task and are asked to perform an additional task when a particular stimulus (the PM cue) is presented. In this study three experiments examined how PM performance depends on stimulus selection, which is a major process involved in executive task control according to current theorizing. Participants made semantic judgments about a target word accompanied by two nontargets (distracters). The target was indicated by its spatial position (Experiment 1) or color (Experiment 2). The findings indicated that PM performance was much poorer when the PM cue was irrelevant to the ongoing task, in spite of the fact that nontargets were processed semantically as shown in Experiment 3.     

On Ultrafilter Logic and Special Functions

Logics for generally were introduced for handling assertions with vague notions,such as generally, most, several, etc., by generalized quantifiers, ultrafilter logic being an interesting case. Here, we show that ultrafilter logic can be faithfully embedded into a first-order theory of certain functions, called coherent. We also use generic functions (akin to Skolem functions) to enable elimination of the generalized quantifier. These devices permit using methods for classical first-order logic to reason about consequence in ultrafilter logic.Presented by André Fuhrmann     

Effects of orthographic consistency, frequency, and letter knowledge on children's vowel spelling development

This study investigated children's sensitivity to spelling consistency, and lexical and sublexical (rime) frequency, and their use of explicitly learned canonical vowel graphemes in the early stages of learning to spell. Vowel spellings produced by 78 British children at the end of reception year (mean age 5 years, 7 months) and 6 months later in mid-Year 1 were assessed. Regression analyses revealed that, at both test times, knowledge of sound-letter correspondences influenced spelling performance; however, unconditional consistency of vowel spellings affected children's spelling most strongly, over and above additional effects of word and rime frequency and the complexity of the target vowel grapheme. The effect of conditional consistency of vowel spellings given coda contexts was not significant. Thus, young children are sensitive to various statistical properties of the orthography from the earliest phases of spelling development and, in particular, to the unconditional consistency of the vowel spelling pattern.     

Suicidality in African American men: the roles of southern residence, religiosity, and social support

The rise in suicide by African Americans in the United States is directly attributable to the dramatic, nearly three-fold increase in suicide rates of African American males. Gibbs (1997) hypothesized high social support, religiosity, and southern residence are protective factors against suicidality for Black people. This hypothesis was tested among 5,125 participants from the National Comorbidity Survey; 299 were African American males. In this study we hypothesized that there would be significantly lower suicidality in the South, and social support and religiosity would mediate this relationship. Our results indicate that Southern region is indeed a significant predictor of suicidal symptoms in African American men, such that suicidal symptoms were lower in the South, but religiosity and social support did not account for this effect. Other potential mediators were also examined.
