On the origin of worries about modern health hazards: Experimental evidence for a conjoint influence of media reports and personality traits

Objective: Worries about health threatening effects of potential health hazards of modern life (e.g. electric devices and pollution) represent a growing phenomenon in Western countries. Yet, little is known about the causes of this growing special case of affective risk perceptions termed Modern Health Worries (MHW). The purpose of this study is to examine a possible role of biased media reports in the formation of MHW.

Design: In two experiments, we investigated whether typical television reports affect MHW. In Study 1, 130 participants were randomly assigned to a film on idiopathic environmental intolerance (IEI) or a control film about cystic fibrosis. In Study 2, 82 participants were randomly assigned to either a film on the dangers of electromagnetic fields or a control condition.

Main outcome measures: Increases in MHW after sensational media reports.

Results: In Study 1, only participants high on the personality trait of absorption revealed increased MHW after watching the IEI film. In Study 2, specifically worries about radiation were found to be elevated after watching the film on the dangers of electromagnetic fields compared to the control film.

Conclusion: The results of both studies reveal a significant and specific influence of sensational short mass media reports on MHW. The influence of potential moderators such as absorption remains to be clarified.     

Numerical distance effects in visual search

We present three experiments in which observers searched for a target digit among distractor digits in displays in which the mean numerical target?Cdistractor distance was varied. Search speed and accuracy increased with numerical distance in both target-present and target-absent trials (Exp. 1A). In Experiment 1B, the target 5 was replaced with the letter S. The results suggest that the findings of Experiment 1A do not simply reflect the fact that digits that were numerically closer to the target coincidentally also shared more physical features with it. In Experiment 2, the numerical distance effect increased with set size in both target-present and target-absent trials. These findings are consistent with the view that increasing numerical target?Cdistractor distance affords faster nontarget rejection and target identification times. Recent neurobiological findings (e.g., Nieder, 2011) on the neuronal coding of numerosity have reported a width of tuning curves of numerosity-selective neurons that suggests graded, distance-dependent coactivation of the representations of adjacent numbers, which in visual search would make it harder to reject numerically closer distractors as nontargets.     

Idiopathic Environmental Intolerance: A Treatment Model

Idiopathic environmental intolerance (IEI) refers to a health condition characterized by the presence of multiple symptoms in different organ systems in response to a variety of environmental cues, such as chemical exposures, electromagnetic radiation, infrasound from windmill farms, (parts of) buildings, foods, etc. Typically, the symptoms arise in response to triggers and at dosages that do not cause symptoms in the majority of people, and no clear link with any physiological dysfunction can be found. The condition varies in a dimensional way from very mild, for which no medical help is sought, to very disabling, compromising normal life. The condition is controversial, but several indications strongly suggest that the symptoms result from nocebo mechanisms. Currently, different psychological treatments are explored, but they are generally not based on a clear understanding of the aetiopathological mechanisms and the treatment effects are not well documented. In the present paper, we describe a treatment protocol based on a comprehensive explanatory model of IEI. The goal is to contribute to standardized, mechanism-based treatments as a basis for more systematic treatment studies.     

Can faith move mountains? How implicit theories about willpower moderate the adverse effect of daily emotional dissonance on ego-depletion at work and its spillover to the home-domain

Recent findings have demonstrated that implicit theories about willpower (the belief whether willpower relies on a limited vs. nonlimited resource) moderate the ego-depletion-effect. This study examines this moderating mechanism in occupational settings where employees increasingly have to deal with the unpleasant state of emotional dissonance, which requires the exertion of volitional self-control. By integrating findings on implicit theories about willpower, arguments brought up by the strength model of self-control, and notions from the spillover literature, we propose that believing in a nonlimited resource theory of willpower buffers the effect of emotional dissonance on ego-depletion at work and diminishes the spillover of ego-depletion from the work- to the home-domain. In a diary study covering 10 working days (N = 71), we examine a moderated mediation model in which ego-depletion at work mediates the relation between emotional dissonance and ego-depletion at home and analyse whether implicit theories about willpower moderate both paths (a and b) of the proposed mediation model. Our results provide support for the mediation hypothesis and show that endorsing a nonlimited resource theory buffers the effect of emotional dissonance on ego-depletion at work, thereby disrupting the indirect effect of emotional dissonance on ego-depletion at home. Subsequently, we discuss implications of holding a nonlimited resource theory.     

A review of applicant faking in selection interviews

Interviews are commonly used for selection but research on interview faking only gained momentum relatively recently. We review both theoretical and empirical work on prevalence, antecedents, processes, and effects of interview faking. Most applicants fake at least to some degree. Personality (e.g., Conscientiousness, Honesty‐humility, the Dark Triad) and attitudes toward faking substantially correlate with faking behaviors. Research concerning applicants' ability, interview structure components, or contextual factors is limited. Furthermore, the impact of faking on interview ratings is mixed and effects on criterion‐related validity are not consistently negative. Finally, the detection of faking seems hardly possible and there are limited options available to reduce interview faking. Throughout our review, we describe important gaps and derive suggestions and propositions for future research.     

Food cue exposure and body image satisfaction: the moderating role of BMI and dietary restraint

Effects of cue exposure to high and low-caloric food on body image satisfaction and the moderating role of body mass index (BMI) and restraint were investigated in 77 lean unrestrained, lean restrained and overweight restrained females. Body (BS) and weight satisfaction (WS) were assessed before and after the cue exposure. Lean restrained participants were significantly less satisfied with their weight after cue exposure to high-caloric foods in comparison to cue exposure to low-caloric foods, whereas no such effect was present in overweight restrained and lean unrestrained participants. Low-caloric food cues did not influence WS. Food cues had a nonsignificant trend effect on BS. Yet, only lean unrestrained participants experienced significantly more BS in response to food cue exposure.     

Identification of the targeted performance dimensions and self-promotion in interviews: investigations of uncharted waters

ABSTRACT

Previous research on interviewees’ ability to identify criteria (ATIC) found that interview performance is positively related to the degree to which interviewees identify the targeted performance criteria in a selection interview. Similarly, the use of self-promotion as an impression management tactic is also positively related to interview performance. The present study extended this research and used multilevel analyses to investigate whether intraindividual variation concerning identification of the performance criteria and the use of self-promotion is related to within-person performance fluctuations across interview questions. Furthermore, we also tested whether correct identification of the performance dimensions moderates the effects of self-promotion behaviour on interview performance. In a simulated selection interview, we found that ATIC and self-promotion were indeed positively related to interview performance on the between-person level (i.e., for the entire interview). However, no moderator effect was found. Furthermore, on the within-person level interviewees’ performance was better concerning questions for which they were better at identifying the performance criteria but worse concerning questions for which they used more self-promotion. Thus, identification of the targeted dimensions and self-promotion have diverging effects on the level of specific interview questions. Finally, we discuss implications for research and practice.
