Effects of Changing Proportions of the Sexes on Ratings of Occupational Prestige

Touhey (1974) has suggested that an influx of women into high-status, male-dominated professions will result in declining prestige and desirability for those professions. The present study attempts both a replication and an extension to examine results of changing sex ratios in low-status and female-dominated occupations. Replication of the previous finding and its predicted extension to high- status women's jobs occurred only with college sophomores; juniors and seniors generally did not respond to sex composition, although they did rate high-status men's jobs as even more prestigious with a larger proportion of women employed in the job. Results for the low-status jobs were less clear, possibly reflecting the distance of college students from such occupations. Unlike Touhey's, these results are not interpreted as predicting future occupational prestige, but only as reflecting current attitudes about women and men.     

Relationships between Facets of Job Satisfaction and Task and Contextual Performance

This study examined the relationship between job satisfaction and task and contextual performance. Specifically, it assessed this relationship for overall as well as facets of job satisfaction. Four hundred and forty‐four employees in a manufacturing plant completed measures of job satisfaction and their supervisors completed measures of task and contextual job performance. Results indicate that the relationships between overall job satisfaction and task and contextual performance were the same. However, when the facets of job satisfaction were considered, different relationships emerged. There was a stronger relationship between satisfaction with supervision and contextual performance compared to task performance. In contrast, there was a stronger relationship between satisfaction with work and task performance compared to contextual performance. Results indicated the importance of considering different facets with the job satisfaction and job performance relationship, as well as the importance of matching predictors and criteria in terms of their levels of specificity. Cette étude examine la relation entre la satisfaction au travail, la tâche et la performance en contexte. Plus spécifiquement, cette relation a étéévaluée en envisageant la relation au travail de façon globale ou selon différentes facettes. La satisfaction au travail a été mesurée auprès de 444 salariés d’une usine de fabrication, la tâche et la performance en contexte ont étéévaluées par leurs supérieurs. Les résultats indiquent que les relations entre la satisfaction au travail envisagée de façon globale, la tâche et la performance en contexte sont les mêmes. Cependant, quand on distingue les facettes de la satisfaction au travail, des relations différentes émergent. Il y a une relation plus importante entre la satisfaction envers la supervision et la performance en contexte qu’entre la satisfaction envers la supervision et la performance. En revanche, il y a une relation plus forte entre la satisfaction du travail et la performance qu’entre la satisfaction du travail et la performance en contexte. Les résultats indiquent l’importance de trouver des indicateurs et des critères qui rendent compte de ces spécificités.     

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.     

Deduction from Uncertain Premises

We investigate how the perceived uncertainty of a conditional affects a person's choice of conclusion. We use a novel procedure to introduce uncertainty by manipulating the conditional probability of the consequent given the antecedent. In Experiment 1, we show first that subjects reduce their choice of valid conclusions when a conditional is followed by an additional premise that makes the major premise uncertain. In this we replicate Byrne (1989). These subjects choose, instead, a qualified conclusion expressing uncertainty. If subjects are given a third statement that qualifies the likelihood of the additional premise, then the uncertainty of the conclusions they choose is systematically related to the suggested uncertainty. Experiment 2 confirms these observations in problems that omit the additional premise and qualify the first premise directly. Experiment 3 shows that the qualifying statement also affects the perceived probability of the consequent given the antecedent of the conditional. Experiment 4 investigates the effect of suggested uncertainty on the fallacies and shows that increases in uncertainty reduce the number of certain conclusions that are chosen while affirming the consequent but have no effect on denying the antecedent. We discuss our results in terms of rule theories and mental models and conclude that the latter give the most natural account of our results.
