Job demands–resources model in the context of recovery: Testing recovery experiences as mediators

The aim of the present study was to extend the original Job Demands–Resources (JD-R) model by taking into account recovery as an important mediation mechanism between work characteristics and well-being/ill-health. Specifically, we examined whether recovery experiences—strategies promoting recovery—might have a mediating role in the JD-R model among 527 employees from a variety of different jobs. The results showed that psychological detachment fully mediated the effects of job demands on fatigue at work and mastery partially mediated the effects of job resources on work engagement. Altogether, the results suggest that recovery merits consideration as a mediating mechanism in the JD-R model.     

Feedback environment and well-being at work: The mediating role of personal control and feelings of helplessness

This study examines employees' personal control and feelings of helplessness at work as partial mediators of the relationship between the supervisor–employee feedback environment and well-being (job satisfaction, job depression, job anxiety, turnover intentions) at work. Findings are reported from a cross-sectional field study with 345 participants from three different industries. Hierarchical regression analyses showed that feedback environment was positively related to job satisfaction, personal control over information and decisions, and was negatively related to helplessness, job depression, and turnover intentions. Furthermore, personal control partially mediated the relationships between feedback environment and job satisfaction as well as job depression. Helplessness partially mediated the relationships between feedback environment and job depression, job satisfaction, and turnover intentions. This study adds to the literature on feedback environment in highlighting the importance of the supervisor–employee feedback environment for well-being at work and introducing personal control and helplessness as mediating variables.     

The dark and the bright sides of proactive work behaviour and situational constraints: Longitudinal relationships with task conflicts

We investigated relationships of a job stressor (situational constraints) and specific proactive behaviours with change in task conflicts over time. We introduced two distinct types of proactive work behaviour (promotion-oriented initiative and prevention-oriented initiative) and examined their positive but also negative relationships with change in task conflicts. Study 1 supported the construct validity of promotion-oriented initiative and prevention-oriented initiative for 363 student assistants: Confirmatory factor analyses indicated that both types of proactive behaviour were distinct constructs and also distinct from active coping; patterns of correlations were similar to those of a prior concept of proactive behaviour. Study 2 was a longitudinal online survey with 197 employees over 3 weeks. Consistent with our hypotheses, situational constraints and promotion-oriented initiative predicted an increase in task conflicts, whereas prevention-oriented initiative predicted a decrease in task conflicts.     

L’auto efficacité créative,la flexibilité cognitive et le soutien à l’innovation comme antécédents du comportement innovant

The necessity to innovate is a concern for many practitioners and researchers. This research aims to demonstrate the role of cognitive flexibility and of the climate of support for innovation in developing innovative behavior at work. The mediating role of creative self-efficacy is tested. The results confirm that cognitive flexibility and the climate for work group innovation are antecedents of the innovative behavior.     

The irrelevant sound effect in short-term memory: Is there developmental change?

With two experiments, effects of irrelevant speech and classroom noise on serial recall of common nouns presented pictorially were investigated in children and adults. Experiment 1 used fixed list lengths for children (first graders) and adults. Experiment 2 used list lengths adjusted to participants' (second–third graders, adults) individual spans. In both experiments, children and adults were equally impaired by irrelevant speech. This contrasts with a related study (differences in methodology) by Elliott (2002), who reported severe increase in the detrimental impact of irrelevant speech with decreasing age. In both experiments, classroom noise had no effect in overall analyses. For Experiment 1, however, separate group analyses revealed impairment in children. Results suggest that effects of irrelevant sounds on serial recall stem from two separate mechanisms: Specific interference due to the sounds' automatic access to short-term memory, and/or attention capture. Only for the latter there is developmental change.     

The phenomenology of self-reported body dysmorphic disorder by proxy

Body dysmorphic disorder by proxy (BDDBP), a preoccupation with a perceived defect in another person's appearance may represent a variant of BDD. However, BDDBP has received little empirical attention. We present here the phenomenology of 11 individuals with self-reported BDDBP. Participants completed an internet-based survey that assessed symptoms, psychosocial impact, and treatment history. Participants (8 females, 3 males) reported preoccupation with a wide array of individuals (e.g., spouse, stranger). Body parts of concern most commonly involved the face and head. Most participants spent several (e.g., 3–8) hours per day preoccupied by perceived defects in the person of concern (POC). All participants engaged in rituals to try to alleviate distress or improve the POC's appearance. Most avoided social/occupational activities, including contact with the POC. The impact of BDDBP was profound, particularly on relationships. Findings may help elucidate diagnostic criteria, course, and treatment.     

The relevance of sleep and circadian misalignment for procrastination among shift workers

This daily diary study contributes to current research uncovering the role of sleep for employees’ effective self‐regulation at work. We focus on shift workers’ effective self‐regulation in terms of their general and day‐specific inclination to procrastinate, that is, their tendency to delay the initiation or completion of work activities. We hypothesized that transitory sleep characteristics (day‐specific sleep quality and sleep duration) and chronic sleep characteristics in terms of circadian misalignment are relevant for procrastination. Sixty‐six shift workers completed two daily questionnaires over the course of one work week, resulting in 332 days of analysis. Results of multilevel regression analyses showed that on days when shift workers slept better and longer—compared to days when they slept worse and shorter—they had more energy and willpower available after sleep and subsequently were less prone to procrastination. Moreover, the more work times (permanent shift) were misaligned with employees’ sleep–wake preferences (chronotype) the more pronounced was shift workers’ inclination to procrastinate at work. The present findings provide important implications for shift workers’ effective functioning at work.

Practitioner Points

• To promote shift workers’ effective functioning at work, when scheduling shift work, circadian principles should be taken into account, and work times should be aligned with workers’ chronotypes.
• Day‐specific sleep quality and duration co‐vary with procrastination at work. Thus, on days on which procrastination would be especially harmful, sleep of good quality and of sufficient duration should be obtained.

     

How children perceive fractals: Hierarchical self-similarity and cognitive development

The ability to understand and generate hierarchical structures is a crucial component of human cognition, available in language, music, mathematics and problem solving. Recursion is a particularly useful mechanism for generating complex hierarchies by means of self-embedding rules. In the visual domain, fractals are recursive structures in which simple transformation rules generate hierarchies of infinite depth. Research on how children acquire these rules can provide valuable insight into the cognitive requirements and learning constraints of recursion.     

Modular Cognitive-Behavioral Therapy for Body Dysmorphic Disorder: A Randomized Controlled Trial

There are few effective treatments for body dysmorphic disorder (BDD) and a pressing need to develop such treatments. We examined the feasibility, acceptability, and efficacy of a manualized modular cognitive-behavioral therapy for BDD (CBT-BDD). CBT-BDD utilizes core elements relevant to all BDD patients (e.g., exposure, response prevention, perceptual retraining) and optional modules to address specific symptoms (e.g., surgery seeking).
