Absence of age-related proneness to short-term retroactive interference in the absence of rehearsal

Age differences in short-term retroactive interference, unconfounded with age differences in rehearsal in the retention interval of the Brown-Peterson Task, were not found in a cross-sectional study of adults 18-32 and 64-78 years of age. Degree of retroactive interference was manipulated conjointly with distractor interval length (0-15 s). Individual memory span was assessed and used as the list length in order to achieve stimulus equivalence of memory loads across individuals and age groups. An attention-demanding matching task that adjusted itself in difficulty to the individual's attentional capacity was used as the distractor activity. Covert rehearsal during the retention interval was inferred using several measures, including a comparison of distractor task performance in the presence and in the absence of a memory load, and rehearsers were excluded from the primary analyses. We conclude that there is no interference proneness with increasing age in the present study.     

Evaluation of two test-anxiety reduction treatments in a secondary prevention program

The study evaluated the effectiveness of both a new anxiety management training program and a cognitive modification procedure as part of a secondary prevention effort to identify and treat test anxiety early in the academic career of college students. Subjects were 40 college freshmen who had been identified as high test-anxious in an initial mail-out survey of the Test Anxiety scale. Subjects were randomly assigned to three experimental conditions: anxiety management training, a cognitive modification procedure, and a no-treatment control group. Results indicated that both the cognitive modification and anxiety management training treatments were effective in reducing test anxiety on a posttreatment administration of the Test Anxiety scale. Especially interesting, a significant difference in academic performance emerged between treatment and control groups three semesters after treatment, underscoring the preventive value of the program.     

The Epidemiology of Homicide followed by Suicide: A Systematic and Quantitative Review

This systematic review of population based studies of homicide followed by suicide was conducted to examine the associations between rates of homicide‐suicide, rates of other homicides and rates of suicide. The review analysed 64 samples, including the case of an outlier (Greenland) that were reported in 49 studies. There was a significant association between the rates of homicide‐suicide and those of other homicides in studies from the U.S.A. Outside the U.S.A. there was no clear association between homicide‐suicide and other homicide but there was modest but significant association between rates of suicide and homicide‐suicide. Homicide‐suicide appears to be closer in epidemiological terms to homicide than suicide in regions with high rates of homicide and measures to reduce homicide in these regions may also reduce homicide‐suicide.     

Evaluating the performance of departments of psychotherapy

Conceptual and practical issues which surround attempts at assessing the efficiency of psychotherapy departments are surveyed and the advantages and disadvantages associated with performance indicators reviewed. The issues of assessing efficiency in general and the selection of appropriate indicators at both national and local levels are discussed. It is concluded that it is possible to find indicators which reflect the value of a psychotherapeutic service to the community within which it is based, and that the identification of a generally agreed set of such parameters is a matter of priority.     

Absence of adult age differences in forgetting in the Brown-Peterson Task

Despite some recent evidence to the contrary, no reliable age differences in proactive interference (PI) or retroactive interference (RI) were found in a cross-sectional study of adults aged 18-29 and 63-75. Individual memory span was used as the list length in the Brown-Peterson Task in order to achieve stimulus equivalence of memory loads across individuals and age groups. Data from rehearsers were excluded from the analyses in order to isolate age differences in passive forgetting processes from those in rehearsal. PI was manipulated by presenting categorized or uncategorized memory lists. RI was manipulated, holding distractor task difficulty constant, by using words or tones in a signal detection distractor task. It is concluded that age differences are minimal to nonexistent in passive RI-related processes such as decay and perturbation and in passive PI-related processes such as set effects in semantic encoding.     

Psychosocial Factors and HIV Prevention for Gay,Bisexual, and Other Men Who Have Sex with Men

We are more than 30 years into the HIV epidemic, and, although we have made many important scientific advances, there remains much to understand and implement to prevent new infections. The science of HIV prevention, although interdisciplinary, has relied heavily on psychological theories and research methods to address many key questions. In this paper, we briefly review some historical and epidemiologic considerations about the U.S. HIV epidemic and then present some key psychological concepts from HIV prevention. We make the case for continuing to focus efforts on gay, bisexual, and other men who have sex with men, who represent the sociocultural group with the highest incidence and prevalence of HIV in the domestic epidemic. We present a summary of the research support for, and limitations of, the three major psychosocial models that predict HIV risk behaviors – the information–motivation–behavioral skills model, the minority stress model, and the syndemics framework. We discuss the use of these models in the development and testing of HIV prevention interventions and end by highlighting a few novel research areas, including bio‐behavioral approaches.     

Moderators of the association between relational aggression and perceived popularity

This study, which involved two waves of measurement over a period of 12 months, examined first whether the positive association between relational aggression and two types of high status was moderated by social self-efficacy, leadership, cooperation, and peer sociability. It was expected that relational aggressors are most likely to gain high peer group status when they are also self-efficacious or prosocial. Second, this study examined the reciprocal association between relational aggression and high peer status. It was anticipated that relational aggression would contribute to higher perceived popularity and vice versa. Third, we also examined and hypothesized reciprocal effects between social self-efficacy, leadership, cooperation, and peer sociability and perceived popularity. Youth were 540 13-15 year olds participating in Grade 7 (Time 1) and again 1 year later in Grade 8 (Time 2). Data were collected from peers, teachers, and the adolescents themselves. Consistent with expectations, relationally aggressive adolescents high in social self-efficacy, leadership, cooperation, and peer sociability were higher in status than relationally aggressive individuals with low levels of these characteristics. In addition, relational aggression and perceived popularity reciprocally influenced each other. Finally, social self-efficacy, leadership, cooperation, and peer sociability reciprocally influenced and were influenced by perceived popularity.
