The role of partners and children for employees' daily recovery

This multi-source diary study examined the role of partners for employees' daily recovery in a sample of dual-earner couples. We hypothesized that employees' daily psychological detachment from work during the evening should be positively associated with their partners' daily psychological detachment during the evening. Employees' affective well-being (serenity and negative activation) at bedtime should be influenced not only by their own psychological detachment, but also by their partners' psychological detachment. Moreover, we hypothesized that the presence of children in a couple's household should moderate the relations between partners' psychological detachment on the one hand, and employees' psychological detachment and affective well-being on the other hand. Fifty-three dual-earner couples completed daily electronic surveys via handheld devices at bedtime over the course of one work week. We used dyadic multilevel path modeling to analyze our data. Results showed that employees' and their partners' levels of daily psychological detachment were positively related. Employees' psychological detachment predicted their own negative activation, but not their serenity at bedtime. Partners' psychological detachment predicted employees' serenity and negative activation only in couples without children. Hence, our study provides support for the relevance of partners and children for employees' daily recovery after work.     

Explicit awareness supports conditional visual search in the retrieval guidance paradigm

In four experiments we explored whether participants would be able to use probabilistic prompts to simplify perceptually demanding visual search in a task we call the retrieval guidance paradigm. On each trial a memory prompt appeared prior to (and during) the search task and the diagnosticity of the prompt(s) was manipulated to provide complete, partial, or non-diagnostic information regarding the target's color on each trial (Experiments 1–3). In Experiment 1 we found that the more diagnostic prompts was associated with faster visual search performance. However, similar visual search behavior was observed in Experiment 2 when the diagnosticity of the prompts was eliminated, suggesting that participants in Experiment 1 were merely relying on base rate information to guide search and were not utilizing the prompts. In Experiment 3 participants were informed of the relationship between the prompts and the color of the target and this was associated with faster search performance relative to Experiment 1, suggesting that the participants were using the prompts to guide search. Additionally, in Experiment 3 a knowledge test was implemented and performance in this task was associated with qualitative differences in search behavior such that participants that were able to name the color(s) most associated with the prompts were faster to find the target than participants who were unable to do so. However, in Experiments 1–3 diagnosticity of the memory prompt was manipulated via base rate information, making it possible that participants were merely relying on base rate information to inform search in Experiment 3. In Experiment 4 we manipulated diagnosticity of the prompts without manipulating base rate information and found a similar pattern of results as Experiment 3. Together, the results emphasize the importance of base rate and diagnosticity information in visual search behavior. In the General discussion section we explore how a recent computational model of hypothesis generation (HyGene; Thomas, Dougherty, Sprenger, & Harbison, 2008), linking attention with long-term and working memory, accounts for the present results and provides a useful framework of cued recall visual search.     

Source reliability and the conjunction fallacy

Information generally comes from less than fully reliable sources. Rationality, it seems, requires that one take source reliability into account when reasoning on the basis of such information. Recently, Bovens and Hartmann (2003) proposed an account of the conjunction fallacy based on this idea. They show that, when statements in conjunction fallacy scenarios are perceived as coming from such sources, probability theory prescribes that the "fallacy" be committed in certain situations. Here, the empirical validity of their model was assessed. The model predicts that statements added to standard conjunction problems will change the incidence of the fallacy. It also predicts that statements from reliable sources should yield an increase in fallacy rates (relative to unreliable sources). Neither the former (Experiment 1) nor the latter prediction (Experiment 3) was confirmed, although Experiment 2 showed that people can derive source reliability estimates from the likelihood of statements in a manner consistent with the tested model. In line with the experimental results, model fits and sensitivity analyses also provided very little evidence in favor of the model. This suggests that Bovens and Hartmann's present model fails to explain fully people's judgements in standard conjunction fallacy tasks.     

Examining the role of emotional avoidance in the relationship between posttraumatic stress disorder symptom severity and worry

A growing body of literature suggests that worry is a cognitive activity functioning to avoid unpleasant internal experiences such as negative thoughts, emotions, and somatic responses. Given the highly aversive internal events associated with posttraumatic stress disorder (PTSD), individuals experiencing PTSD symptoms following exposure to a traumatic event may be particularly motivated to engage in avoidant regulation strategies such as worry. Surprisingly, however, few studies to date have examined the relationship between PTSD and worry as well as potential factors that might explain this association. Therefore, the goal of this study was to examine the association between PTSD symptom severity and worry and the extent to which emotional avoidance explains this relationship. To this end, 207 college students with a history of traumatic exposure (meeting Criterion A for a PTSD diagnosis) completed a series of questionnaires assessing history of exposure to potentially traumatic events, PTSD symptom severity, emotional avoidance tendencies, and worry. Results demonstrated that PTSD symptom severity was positively associated with worry and emotional avoidance. Further, emotional avoidance was found to fully account for this relationship, providing support for the proposed emotionally avoidant function of worry. The implications of these findings for future research and the treatment of worry among individuals with a history of traumatic exposure are discussed.     

The role of partners for employees' recovery during the weekend

We examined the effects of positive and negative experiences with the partner (absorption in joint activities and conflict with the partner) during the weekend on affective states at the beginning of the following work week and tested whether recovery experiences (psychological detachment, relaxation, and mastery experiences) mediated these effects. In total, 269 university faculty members completed online surveys before and after the weekend. Hierarchical regression analyses revealed that absorption in joint activities with the partner predicted recovery experiences during the weekend and increased positive affective states (vigor, joviality, serenity) at the beginning of the following work week. Relaxation mediated the effects of absorption in joint activities on positive affective states. Conflict with the partner increased negative affective states (negative activation, fatigue), but was unrelated to recovery experiences. Our findings emphasize the importance of experiences with the partner for employees' recovery and show that the social environment of employees matters for their recovery.     

Similarity-based asymmetries in perceptual matching

Asymmetries, where response times differ depending on the order of two stimuli, have been widely used to explore fundamental aspects of perceptual processing. Given how much is made of asymmetries in the study of perception there has been surprisingly little research into the cognitive mechanisms that may underlie why comparing two objects in isolation depends on the order of presentation. In visual search, for example, asymmetries are typically attributed to fundamental processing characteristics as opposed to the inherent relation between two stimuli. However, one possible explanation for asymmetries found in perceptual processing is that similarity is important in the task and it is similarity itself that is asymmetric. In the current paper, we use a stimulus set for which the transformational account of similarity predicts asymmetries based on differences in transformational complexity. Using the fine-grained measure of reaction time we show that directional differences in transformation distance successfully predict asymmetries in the speed of matching two stimuli in sequence. The results are discussed in relation to the role of transformations in perceptual identification more generally, and how transformations could be revealing about how objects are compared in other experimental contexts where objects are compared directionally (e.g., visual search).     

THE ATTITUDES TOWARD WOMEN SCALE AND ATTITUDE CHANGE IN COLLEGE STUDENTS

To determine cohort changes in gender-role attitudes, responses to the 15-item form of the Attitudes Toward Women Scale (AWS; Spence & Helmreich, 1972a, 1978) were compared for students at the same university tested in 1972, 1976, 1980, and 1992. In both males and females, members of the 1992 cohort were the most egalitarian, and members of the 1972 cohort were the least egalitarian. In all groups, women were significantly less traditional in their attitudes than men. As has been found in previous studies, detailed analyses of the data from the 1992 cohort revealed that the scale was unifactorial, but that the score distributions were skewed. There was also some indication of ceiling effects at the egalitarian end of the scale, particularly in women. The implications of these latter results for the usefulness of the AWS in current research were explored.
