The Effects of Children's Exposure to Domestic Violence: A Meta-Analysis and Critique

A wide range of children's developmental outcomes are compromised by exposure to domestic violence, including social, emotional, behavioral, cognitive, and general health functioning. However, there are relatively few empirical studies with adequate control of confounding variables and a sound theoretical basis. We identified 41 studies that provided relevant and adequate data for inclusion in a meta-analysis. Forty of these studies indicated that children's exposure to domestic violence was related to emotional and behavioral problems, translating to a small overall effect (Z _r = .28). Age, sex, and type of outcome were not significant moderators, most likely due to considerable heterogeneity within each of these groups. Co-occurrence of child abuse increased the level of emotional and behavioral problems above and beyond exposure alone, based on 4 available studies. Future research needs are identified, including the need for large-scale longitudinal data and theoretically guided approaches that take into account relevant contextual factors.     

Neuropsychological Performance in Gulf War Era Veterans: Motivational Factors and Effort

Assuming that the underlying etiology of unexplained health-related symptoms in returning Gulf War (GW) veterans is multifactorial, the possible role of feigning or exaggeration of symptoms is worth consideration as a contributing factor. The present study assessed the relationship between motivation to perform well during neuropsychological assessment and objective neuropsychological test performance. Motivation was measured as the score on a visual memory task (Test of Memory Malingering, TOMM) of low difficulty. Participants included 77 veterans from the cohorts of GW- (n = 58) and Germany-deployed (n = 19) GW-era veterans described in two other papers in this issue who were administered the TOMM. Most veterans earned perfect or near-perfect scores on the TOMM (48–50/50). Scores 47 were associated with lower scores on neuropsychological tasks assessing attention, executive functions, and memory. Variability in test performance within and between tasks measuring similar functions was also found in participants with lower TOMM scores.     

Do multielement visual tracking and visual search draw continuously on the same visual attention resources?

Multielement visual tracking and visual search are 2 tasks that are held to require visual-spatial attention. The authors used the attentional operating characteristic (AOC) method to determine whether both tasks draw continuously on the same attentional resource (i.e., whether the 2 tasks are mutually exclusive). The authors found that observers can search and track within the same trial significantly better than would be predicted if the 2 tasks were mutually exclusive. In fact, the AOC for tracking and search is similar to that for tracking and auditory monitoring. The results of additional experiments support an attention-switching account for this high level of dual-task performance in which a single attentional resource is efficiently switched between the tracking and search. The results provide important constraints for architectures of visual selective attention and the mechanisms of multielement tracking.     

Using Authorware Professional for developing courseware

This paper describes the use of Authorware Professional, an icon-based, object-oriented authoring system, to develop courseware and on-line experiments. Notable features include direct editability, facility with many response types, and built-in variables. Shortcomings include the difficulty of learning how to use the program, inability to present stimuli rapidly, the program’s linear development style, weak drawing tools, a lack of scroll bars for text, and some problems in the use of Authorware with other applications. Overall, the package is recommended for users with adequate resources.     

Inhibitory tagging in visual search: a failure to replicate

Klein (1988) reported that increased reaction times for the detection of small light probes could be used as an indicator of inhibitory tagging of rejected distractors in serial visual search tasks. Such a paradigm would be very useful in the study of the mechanics of visual search. Unfortunately, we cannot replicate the result. In this study, we found that probe reaction times were elevated at all distractor locations, relative to empty locations, following both parallel and serial search tasks. This appears to be a forward masking effect.     

Locus of control and achievement in child psychiatric inpatients

The relationship between the Nowicki-Strickland Locus of Control Scale for Children (Nowicki & Strickland, 1973) and academic achievement was examined in a sample of 66 child psychiatric inpatients. Previous studies had suggested that this measure correlated with achievement in normal samples (Nowicki & Strickland, 1973) but not in populations of male juvenile offenders (Little & Kendall, 1978). The product-moment correlation between the Nowicki-Strickland Scale and the Peabody Individual Achievement Test was significant. However, when the effect of IQ was controlled for in a partial correlation, there was no significant correlation. Discussion focuses on the relationship between these results and other findings in the area of locus of control, intelligence, and achievement.     

Women and AIDS-related concerns. Roles for psychologists in helping the worried well

Acquired Immunodeficiency Syndrome (AIDS) has important implications for the practice of psychology. As the epidemic continues, the role of behavior change and psychosocial factors in the spread and transmission of Human Immunodeficiency Virus (HIV) infections assumes increasing significance. Psychologists, as behavior change experts, have a special and challenging role to play in educating the public, particularly women, about AIDS. This article examines AIDS- and HIV-related concerns in women with a focus on the personal dilemmas for the practicing psychologist, problems in health behavior advocacy, and methods and pitfalls in modifying sexual behaviors.     

What Can 1 Million Trials Tell Us about Visual Search?

In a typical visual search experiment, observers look through a set of items for a designated target that may or may not be present. Reaction time (RT) is measured as a function of the number of items in the display (set size), and inferences about the underlying search processes are based on the slopes of the resulting RT × Set Size functions. Most search experiments involve 5 to 15 subjects performing a few hundred trials each. In this retrospective study, I examine results from 2,500 experimental sessions of a few hundred trials each (approximately 1 million total trials). These data represent a wide variety of search tasks. The resulting picture of human search behavior requires changes in our theories of visual search.     

Self-monitoring and sex as moderator variables in the statistical explanation of self-reported marijuana and alcohol use

Self-monitoring and sex are examined as likely moderators of some of the known effective predictors of self-reported use of marijuana and alcohol. The theory of self-monitoring implies that in comparisons between low and high self-monitors, dispositional predictors account for more of the variance in reported use among low self-monitors and environmental predictors account for more of the variance among high self-monitors. With the two classes of predictors established via principal-components analysis and with subgroups defined by scores on Snyder's Self-Monitoring Scale, data from 807 college students showed that self-monitoring does not affect the action of either dispositional or environmental predictors. Thus, the self-monitoring construct promises explanatory leverage that in these tests, the scale is not able to deliver. When subgroups are defined by sex, analyses of reported alcohol use yield small but significant moderator effects: Women's use is more predictable from environmental variables, whereas men's use is more predictable from dispositional variables. These effects are consistent with the conclusions of recent meta-analyses of results from studies of sex differences in conformity to group pressures.
