Social risk and protective factors for suicide attempts in low income African American men and women

A case-control study was conducted to examine a broad array of potential social risk and protective factors for suicide attempt among 200 African American men and women receiving care at a large, public, urban hospital. Specifically, we examined the effect of the following potential risk factors for suicide attempt: life hassles, partner abuse, partner dissatisfaction, and racist events; as well as the following potential protective factors: effectiveness of obtaining resources, social embeddedness, and social support. Using logistic regression, suicide attempter status was predicted by two independently significant social variables: one risk factor (life hassles) and one protective factor (social support). Male versus female suicide attempters were not distinguished by the social variables. These findings, which support the utility of an ecological conceptualization of risk and protective factors for suicide attempt, help to clarify the independently significant social environment risk and protective factors for suicide attempts among economically disadvantaged African Americans in particular. Research on both risk factors and protective factors provide a basis for culturally competent interventions aimed at reducing both the risk of future suicide attempts and completions.     

Modes of cognitive control in recognition and source memory: Depth of retrieval

Recognition memory is usually regarded as a judgment based on trace strength or familiarity. But recognition may also be accomplished by constraining retrieval so that only sought after information comes to mind (source-constrained retrieval). We introduce amemory-for-foils paradigm that provides evidence for source-constrained retrieval in recognition memory (Experiment 1) and source memory (Experiment 2). In this paradigm, subjects studied words under deep or shallow encoding conditions and were given a memory test (recognition or source) that required them to discriminate between new items (foils) and either deep or shallow targets. A final recognition test was used to examine memory for the foils. In both experiments, foil memory was superior when subjects attempted to retrieve deep rather than shallow targets on the earlier test. These findings support a sourceconstrained retrieval view of cognitive control by demonstrating qualitative differences in the basis for memory performance.     

The power of statistical tests for moderators in meta-analysis

Calculation of the statistical power of statistical tests is important in planning and interpreting the results of research studies, including meta-analyses. It is particularly important in moderator analyses in meta-analysis, which are often used as sensitivity analyses to rule out moderator effects but also may have low statistical power. This article describes how to compute statistical power of both fixed- and mixed-effects moderator tests in meta-analysis that are analogous to the analysis of variance and multiple regression analysis for effect sizes. It also shows how to compute power of tests for goodness of fit associated with these models. Examples from a published meta-analysis demonstrate that power of moderator tests and goodness-of-fit tests is not always high.     

Stereotypes as dominant responses: on the "social facilitation" of prejudice in anticipated public contexts

This article challenges the highly intuitive assumption that prejudice should be less likely in public compared with private settings. It proposes that stereotypes may be conceptualized as a type of dominant response (C. L. Hull, 1943; R. B. Zajonc, 1965) whose expression may be enhanced in public settings, especially among individuals high in social anxiety. Support was found for this framework in an impression formation paradigm (Experiment 1) and in a speeded task designed to measure stereotypic errors in perceptual identification (Experiment 2). Use of the process dissociation procedure (B. K. Payne, L. L. Jacoby, & A. J. Lambert, in press) demonstrated that these effects were due to decreases in cognitive control rather than increases in stereotype accessibility. The findings highlight a heretofore unknown and ironic consequence of anticipated public settings: Warning people that others may be privy to their responses may actually increase prejudice among the very people who are most worried about doing the wrong thing in public.     

Sex education sources and attitudes toward sexual precautions across a decade

75 college students responded to Moore and Barling's AIDS questionnaire. Coopersmith's Self-esteem Inventory, and a background survey regarding sex education and sexual and religious activity. The most commonly reported sources of sex education were peers, parents, and high school courses, respectively. Ratings of the most important of 10 potential sources of sex education included peers, high school courses, and religious institutions, respectively. None of these were significantly correlated with future condom use. Virgins reported more open communication with parents about sex. Sexual experience was positively related to more confusion about sexual precautions but negatively related to foreclosed attitudes toward such precautions. Some types of religious involvement (church attendance and campus religious organization membership) were related to foreclosed attitudes. Data in attitudinal and sex education were compared with data collected in 1991. Although students more frequently reported having received sex education in 2000, their attitudes toward utilizing sexual precautions have become somewhat more diffused.     

Strategy-dependent changes in memory: Effects on behavior and brain activity

In the present study, an implicit strategy manipulation was used to explore the contribution of memory strategy to brain activation and behavioral performance. Participants were biased to use either a short-term (maintenance-focused) or long-term (retrieval-focused) memory strategy within a single memory task through manipulation of task context. In comparing directly matched trials across the different task contexts, we observed clear changes in both behavioral performance and brain activity across a network of regions located primarily within lateral and medial frontal cortex. These effects of the memory strategy manipulation suggest that when a retrieval-focused strategy is induced, mnemonic processes are preferentially engaged during the encoding period. In contrast, when a maintenance-focused strategy is induced, mnemonic processes are preferentially engaged during the delay and response periods. Taken together, the results imply that covert cognitive strategies play an important role in modulating brain activation and behavior during memory tasks.     

Relaxing decision criteria does not improve recognition memory in amnesic patients

An important question about the organization of memory is whether information available in non-declarative memory can contribute to performance on tasks of declarative memory. Dorfman, Kihlstrom, Cork, and Misiaszek (1995) described a circumstance in which the phenomenon of priming might benefit recognition memory performance. They reported that patients receiving electroconvulsive therapy improved their recognition performance when they were encouraged to relax their criteria for endorsing test items as familiar. It was suggested that priming improved recognition by making information available about the familiarity of test items. In three experiments, we sought unsuccessfully to reproduce this phenomenon in amnesic patients. In Experiment 3, we reproduced the methods and procedure used by Dorfman et al. but still found no evidence for improved recognition memory following the manipulation of decision criteria. Although negative findings have their own limitations, our findings suggest that the phenomenon reported by Dorfman et al. does not generalize well. Our results agree with several recent findings that suggest that priming is independent of recognition memory and does not contribute to recognition memory scores.     

Human Eyeblink Classical Conditioning: Effects of Manipulating Awareness of the Stimulus Contingencies

Obsessive-compulsive disorder (OCD) is an intrusive and debilitating condition in which the individual experiences uncontrollable thoughts, compulsions, and urges. Successful treatments for OCD are based on Mowrer's theory of fear and avoidance behavior, which predicts that OCD subjects should show accelerated associative conditioning. This prediction was tested in two experiments that com-pared the classical eyeblink conditioning of OCD-like and control college students. OCD and control subjects learned normally and similarly when the conditioning procedure was accompanied by an active visual search background task (Experiment 1). However, when the background task was changed so that subjects passively viewed neutral pictures, OCD subjects conditioned significantly faster than control subjects (Experiment 2). Overall, the performance of all subjects in Experiment 1 was superior to the performance of subjects in Experiemnt 2.
