Psychophysiology of aggression, psychopathy, and conduct problems: a meta-analysis

A meta-analysis of 95 studies was conducted to investigate the relations of heart rate (HR) and electrodermal activity (EDA) with aggression, psychopathy, and conduct problems. Analyses revealed a complex constellation of interactive effects, with a failure in some cases of autonomic patterns to generalize across antisocial spectrum behavior constructs. Low resting EDA and low task EDA were associated with psychopathy/sociopathy and conduct problems. However, EDA reactivity was positively associated with aggression and negatively associated with psychopathy/sociopathy. Low resting HR and high HR reactivity were associated with aggression and conduct problems. Physiology--behavior relations varied with age and stimulus valence in several cases. Empirical and clinical implications are discussed.     

Marital discord and child behavior problems: A meta-analysis

The relation of marital discord to the behavior problems of children was examined through a meta-analysis of the results of prior research. The sample comprised all published studies through 1988 that met criteria for the metaanalysis and that could be located through a combined computer and hand search of the literature. Marital discord included conflict, disharmony, and lack of agreement between currently married parents. Child behavior problems were defined as conduct problems, excluding internalized difficulties, such as anxiety. Four hypotheses were drawn from recent reviews of studies on this topic: The relation between marital conflict and child behavior problems will be (1) positive overall and will be stronger (2) for boys than for girls, (3) for cases based entirely on parent self-report data than for cases involving external sources of data, (4) for clinic than for nonclinic families. Results supported the first three hypotheses. Little evidence was found for an association between marital conflict and the behavior problems of girls. Findings are discussed in terms of their methodological and theoretical implications and in relation to a recent review of research on sex differences in children's reactions to divorce.     

A meta-analysis of burnout with job demands, resources, and attitudes

A meta-analysis was conducted on job demands, resources, and attitudes and their relation with burnout in regard to the COR theory. The version of the Maslach Burnout Inventory used was explored as a moderator of the aforementioned variables. Results suggest that higher demands, lower resources, and lower adaptive organizational attitudes are associated with burnout. In particular, results of the current study show stronger relations than previous meta-analysis (Lee & Ashforth, 1996) have suggested. The scale type also provided some evidence of moderation, with stronger effects found in samples that utilized the MBI-HSS. Implications of the findings in relation to the COR theory and future research directions to clarify the relation between job demands, job resources, organizational attitudes and burnout are discussed.     

Even counselors have irrational ideas

The author examines several of Ellis' “irrational ideas” as they relate specifically to counselors. These ideas provide a convenient vehicle for the discussion of some typical misconceptions about counseling. Counselors are encouraged to analyze their own feelings and thought processes and to determine irrational ideas in addition to those described here to which they may be susceptible.

Prospective linkages between peer victimization and externalizing problems in children: a meta-analysis

Previous meta-analytic research has shown both concurrent and prospective linkages between peer victimization and internalizing problems in youth. However, the linkages between peer victimization and externalizing problems over time have not been systematically examined, and it is therefore unknown if externalizing problems are antecedents of victimization, consequences of victimization, both, or neither. This study provides a meta-analysis of 14 longitudinal studies examining prospective linkages between peer victimization and externalizing problems (n = 7,821). Two prospective paths were examined: the extent to which peer victimization at baseline predicts future residualized changes in externalizing problems, as well as the extent to which externalizing problems at baseline predict future residualized changes in peer victimization. Results revealed significant associations between peer victimization and subsequent residualized changes in externalizing problems, as well as significant associations between externalizing problems and subsequent residualized changes in peer victimization. Hence, externalizing problems function as both antecedents and consequences of peer victimization.     

Maternal work early in the lives of children and its distal associations with achievement and behavior problems: a meta-analysis

This meta-analysis of 69 studies (1,483 effect sizes) used random effects models to examine maternal employment during infancy/early childhood in relation to 2 major domains of child functioning: achievement and behavior problems. Analyses of studies that spanned 5 decades indicated that, with a few exceptions, early employment was not significantly associated with later achievement or internalizing/externalizing behaviors. The exceptions were for teacher ratings of achievement and internalizing behaviors: Employment was associated with higher achievement and fewer internalizing behaviors. Substantial heterogeneity among the effect sizes prompted examination of moderators. Sample-level moderator analyses pointed to the importance of socioeconomic and contextual variables, with early employment most beneficial when families were challenged by single parenthood or welfare status. Maternal employment during Years 2 and 3 was associated with higher achievement. Some moderator analyses indicated negative effects of employment for middle-class and 2-parent families and for very early employment (child's first year). Associations also differed depending on whether effect sizes were adjusted for contextual variables. Only 1 study-level moderator (sex of first author) was significant after adjusting for other moderators. The small effect size and primarily nonsignificant results for main effects of early maternal employment should allay concerns about mothers working when children are young. However, negative findings associated with employment during the child's first year are compatible with calls for more generous maternal leave policies. Results highlight the importance of social context for identifying under which conditions and for which subgroups early maternal employment is associated with positive or negative child outcomes.     

Even in adults,written production is still more costly than oral production

The aim of this research is to show that the mechanical demands of writing continue to affect the characteristics of produced texts in adults under certain situations of cognitive overload. The study reported here is intended to demonstrate that the quality of the text produced by educated adults falls when production is performed in the written rather than in the spoken mode, but only when the elements on the basis of which the texts are to be produced are difficult to relate to one another. In this view, we compared performance in a text production span task in either the oral or the written mode. This task consisted of presenting sets of words, semantically linked or not, from which adults had to produce texts including the words in the set. The results showed that neither the production mode nor the extent of the relationship between the items influenced the number of words recalled. By contrast, the number of ideas elaborated and the coherence of the produced texts are lower when the supplied items are difficult to link and when production is in the written mode. These results are interpreted in the framework of capacity theories in production. They suggest that the cost of managing written production is not always negligible in well‐educated adults. When they have to produce texts on the basis of provided elements that are only weakly associated with one another in the written mode, the residual capacity necessary either to maintain and organise the information in working memory, or to adopt a strategic approach to the composition of the texts, is insufficient because the cost of this elaboration must be added to that of the management of the written production.     

Even in correctable search, some types of rare targets are frequently missed

Socially important visual search tasks, such as airport baggage screening and tumor detection, place observers in situations where the targets are rare and the consequences of failed detection are substantial. Recent laboratory studies have demonstrated that low target prevalence yields substantially higher miss errors than do high-prevalence conditions, in which the same targets appear frequently (Wolfe, Horowitz, & Kenner, 2005; Wolfe et al., 2007). Under some circumstances, this \ldprevalence effect\rd can be eliminated simply by allowing observers to correct their last response (Fleck & Mitroff, 2007). However, in three experiments involving search of realistic X-ray luggage images, we found that the prevalence effect is eliminated neither by giving observers the choice to correct a previous response nor by requiring observers to confirm their responses. This prevalence effect, obtained when no trial-by-trial feedback was given, was smaller than the effect obtained when observers searched through the same stimuli but were given trial-by-trial feedback about accuracy. We suggest that low prevalence puts pressure on observers in any search task, and that the diverse symptoms of that pressure manifest themselves differently in different situations. In some relatively simple search tasks, misses may result from motor or response errors. In other, more complex tasks, shifts in decision criteria appear to be an important contributor.     

Eye movement desensitization and reprocessing for mental health problems: a systematic review and meta-analysis

ABSTRACT

There is no comprehensive meta-analysis of randomised trials examining the effects of Eye Movement Desensitization and Reprocessing (EMDR) on post-traumatic stress disorder (PTSD) and no systematic review at all of the effects of EMDR on other mental health problems. We conducted a systematic review and meta-analysis of 76 trials. Most trials examined the effects on PTSD (62%). The effect size of EMDR compared to control conditions was g = 0.93 (95% CI: 0.67–.18), with high heterogeneity (I²= 72%). Only four of 27 studies had low risk of bias, and there were indications for publication bias. EMDR was more effective than other therapies (g = 0.36; 95% CI: 0.14–0.57), but not in studies with low risk of bias. Significant results were also found for EMDR in phobias and test anxiety, but the number of studies was small and risk of bias was high. EMDR was examined in several other mental health problems, but for none of these problems, sufficient studies were available to pool outcomes. EMDR may be effective in the treatment of PTSD in the short term, but the quality of studies is too low to draw definite conclusions. There is not enough evidence to advise it for the use in other mental health problems.     

Why Even Kim-Style Psychophysical Laws Are Impossible

If the mental is subject to indeterminacy, does this rule out the possibility of psychophysical laws? One might think so. However, Jaegwon Kim has argued for the existence of a kind of psychophysical law that is not obviously susceptible to problems posed by indeterminacy. I begin by introducing a weak and relatively uncontroversial indeterminacy thesis. Then, by appealing to constraints on theories of strong supervenience and to general considerations about the nature of indeterminacy, I argue that even Kim’s laws cannot accommodate indeterminacy. The result is an argument against the possibility of Kim-Style psychophysical laws.     

Reward, punishment, and cooperation: a meta-analysis

How effective are rewards (for cooperation) and punishment (for noncooperation) as tools to promote cooperation in social dilemmas or situations when immediate self-interest and longer term collective interest conflict? What variables can promote the impact of these incentives? Although such questions have been examined, social and behavioral scientists provide different answers. To date, there is no theoretical and/or quantitative review of rewards and punishments as incentives for cooperation in social dilemmas. Using a novel interdependence-theoretic framework, we propose that rewards and punishments should both promote cooperation, and we identify 2 variables—cost of incentives and source of incentives—that are predicted to magnify the effectiveness of these incentives in promoting cooperation.A meta-analysis involving 187 effect sizes revealed that rewards and punishments exhibited a statistically equivalent positive effect on cooperation (d =0.51 and 0.70, respectively). The effectiveness of incentives was stronger when the incentives were costly to administer, compared to free. Centralization of incentives did not moderate the effect size. Punishments were also more effective during iterated dilemmas when participants continued to interact in the same group, compared to both (a) iterated dilemmas with reassignment to a new group after each trial and (b) one-shot dilemmas. We also examine several other potential moderators, such as iterations, partner matching, group size, country, and participant payment. We discuss broad conclusions, consider implications for theory, and suggest directions for future research on rewards and punishment in social dilemmas.     

Backward affective priming: Even when the prime is late, people still evaluate

It is well-established that affective stimuli can prime congruent evaluations if they precede the target within a short time interval, i.e., forward affective priming. The present research examines whether similar effects occur if affective primes succeed target presentation, i.e., backward affective priming. Experiments 1 found short-lived, yet reliable backward affective priming. Experiment 2 found parallel forward affective priming in the same paradigm. Experiment 3 found forward and backward affective priming in a within-subjects design. Comparison with neutral primes suggested that the observed effects were mainly due to interference. Backward affective priming is a robust phenomenon that may reflect a rapid and continuous evaluation of environmental stimuli.     

Coping profiles associated with psychiatric, physical health, work, and family problems

Compares the coping profiles of 11 samples (total N = 1,298) of individuals experiencing psychiatric, physical health, work, or family problems. Comparisons are made in individuals with and without anxiety and depression to control for the effects of distress. Coping was similar for samples in similar problem categories but different for samples in different categories. Psychiatric patients made more use of avoidance and less use of social supports than individuals in the other categories. Samples with physical health problems were among the most frequent users of social supports. Individuals with a family problem were among the most frequent users of problem-focused coping and the least frequent users of self-blame. Groups with work stress were the most frequent users of self-blame. These results suggest that coping profiles may be useful in describing and differentiating groups of stressed individuals.     

The Importance of Overt Responding in Programmed Instruction Even with Added Incentives for Learning

Among the fundamental tenets of programmed instruction is the requirement of overt responding. Past research has not determined when this tenet holds true. We systematically replicated the work of Tudor (1995) by showing that overt responding in computer-based instruction improves learning, even when there is an incentive that might be thought to improve learning enough to mask the effect of overt responding. Subjects were exposed to both read-only and overt-response materials. One group received course-related, bonus points based on posttest performance, whereas the other group received points simply for participation. Within-subject comparison showed greater performance increases when overt responding was required, regardless of the point incentive. No significant differences were found between groups.
