A Brief Delay Decreases Perceived Similarity and Improves Discrimination

A same-different discrimination between the colors of 2 halves of a circle was poorer when the halves were viewed simultaneously than when the delay between viewing them was 33 ms. The simultaneous discrimination also produced a poor performance on different stimuli relative to same stimuli in comparison to the successive discrimination. Poor-on-different performance should indicate high perceived similarity. The simultaneous colors were also judged as more similar. The delay did not alter the physical similarity of the colors. Thus, the delay may have decreased assimilation (perceived similarity) and thereby improved discrimination, in support of the hypothesis that perceived similarity frequently affects discrimination.     

Motives and Likelihood of Bribery: An Experimental Study of Managers in Taiwan

Many studies of bribery acknowledge the important role of bribe-givers, but their true motives remain unclear. We propose that the likelihood of bribery depends on the willingness of an organization to affiliate with local parties or to be successful in a host country, or to have power over local parties. We further argue that different opportunities, either pervasive or arbitrary, facilitate different types of motives that affect the likelihood of bribery. In addition, we investigate the effect of perceived fairness on the likelihood of bribery. We employ a 3 (motives: affiliation vs. achievement vs. power)?×?2 (opportunities: pervasiveness vs. arbitrariness)?×?2 (perceived fairness: high vs. low) factorial design in experimental settings among Executive MBA students in southern Taiwan. Our findings indicate that, when companies perceive a higher level of distributive fairness, high-achieving organizations are more likely to offer a bribe when the condition is pervasive. When they have a powerful motive, arbitrariness engenders a higher likelihood of bribery. When they perceive less distributive fairness, there are no significant differences between motive and opportunity.     

How Social Dominance Orientation Affects Union Participation: The Role of Union Identification and Perceived Union Instrumentality

Bridging social dominance theory and labour studies, this field study investigated the mechanisms underpinning the relationship between rejection of group‐based domination and participation in union activities. Respondents (N = 135) were members of a public sector union in California, that is, a hierarchy‐attenuating institution. Results revealed that union identification mediated the negative relationship between social dominance orientation and active union participation. Moreover, the mediational effect of union identification was moderated by perceived union instrumentality (i.e. outcome‐ and process‐based benefits afforded by the union), indicating that the relationship between union identification and participation was stronger among those union members who consider that the union affects workplace justice. The findings reveal the importance of both identity‐based and instrumental motivations underlying union participation. The novelty of applying social dominance theory to union behaviour is underscored. Copyright © 2012 John Wiley & Sons, Ltd.     

Associations between heart rate,perceived heart rate,and anxiety during acute psychological stress

ABSTRACT

Background: Acute psychological stress elicits increases in heart rate (HR) and anxiety. Theories propose associations between HR, perceived HR, and anxiety during stress. However, anxiety is often measured as a unidimensional construct which limits a comprehensive understanding of these relationships.

Objectives: This research explored whether HR reactivity or perceived HR change was more closely associated with cognitive and somatic anxiety during acute psychological stress.

Design: Two laboratory-based studies were conducted.

Methods: In a single laboratory session, healthy male (N?=?71; study 1) and female (N?=?70; study 2) university students completed three laboratory psychological stress tasks (counterbalanced), each with a preceding baseline. Heart rate, perceived HR change, and cognitive and somatic anxiety intensity and interpretation of anxiety symptoms were assessed immediately following each task. Data were aggregated across tasks.

Results: Actual HR change was unrelated to anxiety intensity, but was associated with more debilitative interpretations of anxiety (study 2). Perceptions of HR change were consistently associated with greater intensity of cognitive (study 1) and somatic (study 1 and 2) anxiety.

Conclusions: Perceived HR rather than actual HR is more closely associated with anxiety intensity during psychological stress. The findings have implications for stress management and the clinical treatment of anxiety symptoms.     

Antecedents and consequences of coping in the anticipatory stage of an exam: A longitudinal study emphasizing the role of affect

Abstract

A longitudinal study with three periods of data collection has been designed to test a model concerning the antecedents and consequences of coping in the anticipatory stage of an examination stress process. The model tested focuses on the role of positive and negative affect at an early stage as the main antecedents for coping. Primary and secondary appraisal, and dispositional variables (perceived personal competence and optimism) have been related to early affect. Moreover, the consequences of coping, considered as the affect measured after the deployment of coping strategies, and the grade obtained in the exam, are also tested. Results show that early affect is the main antecedent of displayed coping strategies. Dispositional variables and appraisal are related to affect, and differential effects of coping in later affect have been noticed. No relationship between coping and grade has been found. Implications for research on coping with examination stress are discussed.     

Association between the Five Factor personality traits and perceived stress: is the effect mediated by general self-efficacy?

Abstract

Ill-health resulting from chronic stress is influenced by personality traits leading to different ways of appraising and coping with life's daily hassles. Using a large population sample the study aimed to investigate possible associations between perceived stress and the personality dimensions of neuroticism, extroversion, openness, agreeableness, and conscientiousness, and to explore the role of general self-efficacy (GSE). A population-based cross-sectional study was conducted at the Research Centre for Prevention and Health, Denmark, in 2006–2008. Men and women (N=3471) aged 18–69, were randomly sampled in the suburbs of Copenhagen. We used the NEO Five-Factor Inventory (NEO-FFI), Cohen's Perceived Stress Scale and the General Self-Efficacy Scale. Negative associations were found between perceived stress and extroversion, conscientiousness, agreeableness, and openness – the latter initially non-significant – whilst neuroticism had a positive association. The associations with agreeableness and openness became positive and significant, respectively, when GSE was included. All five personality-stress models were mediated by GSE, with extroversion and conscientiousness having the strongest mediating effect. The strongest stress-association was found for neuroticism. GSE was shown to change the impact and interpretation of the personality dimensions on perceived stress. These results indicate that GSE is an important factor to consider in the link between personality and perceived stress.     

Does the burden of the experience sampling method undermine data quality in state body image research?

Despite growing popularity of experience sampling methodology (ESM) for evaluations of state-based components of body image, there have been concerns that the frequent repeated measurement might encourage problematic responding resulting in low data quantity and/or quality. Using a sample of 105 women (mean age = 24.84), this study used multilevel modelling to investigate whether (a) there were changes in compliance or response variability across a 7-day period, and (b) whether such changes are explained by participant characteristics. Present findings suggest that demands of ESM protocol undermine quantity more so than quality of obtained data. Decline in procedural compliance across the testing period correlated with BMI and body shame, whereas reduced variability in state-based assessments did not adversely impact the strength of association between state body satisfaction ratings and other variables in the dataset. The authors make several recommendations for ensuring the quality of ESM-based data in future studies.     

Balancing Our Perceptions of the Efficacy of Success-Based Feedback Manipulations on Motor Learning

ABSTRACT. We report two experiments evaluating the impact of success-related feedback on learning of a balance task. In Exp. 1, we studied the influence of lax and conservative outcome feedback, as well as large vs. small improvements in outcome feedback on balance learning. Despite impacts on competency, there were no between-group differences in actual performance or learning. Because no comparative information was provided in Exp. 1, we tested four further groups that either did or did not receive positive or negative comparative feedback (Exp. 2). Although the manipulations influenced competency and arousal, again, there was no impact on balance outcomes. These data cast doubt on the assertions made in the OPTIMAL theory that perceptions of success are moderators of motor learning.
