Individual‐ and group‐level effects of social identification on workplace bullying

A study of 494 employees nested in workgroups from 19 different organizations revealed group identification to be an important factor influencing work-related bullying at both the individual and the group level. Results show that the more employees identified with their group, the less likely they were victims of bullying, which is in line with previous social identity-based analyses of work stress. More importantly, the higher the average level of group identification in the organization, the lower the odds of being a victim versus not being a victim. The latter effect constituted a genuine context effect. These findings redress a neglect of the social bases of workplace bullying and suggest that bullying needs to be understood within a broader perspective of workgroup identities.     

Main and moderating effects of self-control,organizational justice,and emotional labour on counterproductive behaviour at work

Abstract

Considerable attention has been devoted recently to changes in the psychological contract and the implications for HRM. However, much of our understanding of both the socio-cognitive processes involved in the contracting process and the ability of national HRM systems to accommodate the new demands of psychological contracting is accultural or unicultural. This article reviews the content, process, and context of changes in the contract within Europe. A model of the relationship between national culture and other cross-national factors and the process of contracting is developed.     

Empower my decisions: The effects of power gestures on confirmatory information processing

Recent research has shown that social power systematically influences information processing in many ways, and can be induced simply via powerful gestures or postures. The current studies investigated the impact of embodied power on confirmatory information processing after decision making. Based upon previous social power research, we hypothesized that individuals who posed in powerful ways (making a clenched fist or sitting in an open, expansive posture) would systematically prefer decision-consistent over decision-inconsistent information; an effect known as selective exposure, or biased assimilation. Four studies consistently indicated that bodily positioning associated with high levels of power induced greater confirmatory tendencies in the evaluation and search stages of a subsequent, decision-relevant information task (Studies 1–4). This tendency is unlikely to be due to mere physical strain (Study 4), and was mediated by differences in experienced decision certainty (Studies 3 and 4); indicating that the embodiment of high power makes people more confident regarding the validity of their decisions. Consequently, high-power posers systematically prefer information that is consistent with their decision preference.     

Are there ��His�� and ��Her�� Types of Decisions? Exploring Gender Differences in the Confirmation Bias

Research on biased information seeking demonstrates that after decisions, people show a preference for supporting rather than conflicting information (confirmation bias). In a laboratory study (N?=?86 German undergraduates), we examined the interactive effects of different decision types and gender on the confirmation bias. Our study revealed that women showed less confirmation bias when the decision concerned themselves and their mate (interdependent decision) compared to a decision concerning only themselves (independent decision). In contrast, men showed less confirmation bias when they made an independent compared to an interdependent decision. Results were discussed in terms of self-construal differences between men and women leading to different motivations (defense vs. accuracy) during the information seeking depending on the decision type.     

The unresponsive bystander: are bystanders more responsive in dangerous emergencies?

Previous research in bystander intervention found that the presence of other bystanders reduces helping behaviour in an emergency (bystander effect). This research was mainly conducted in the context of non‐dangerous, non‐violent emergencies. We hypothesize that the classic bystander effect does not occur in more dangerous situations because: a) they are faster and more clearly recognized as emergency situations; and b) higher costs for refusing help increase the accepted costs for helping. Following this line of reasoning, the present research tests whether the bystander effect is affected by the degree of the emergency's potential danger. Results supported our expectations: In situations with low potential danger, more help was given in the solitary condition than in the bystander condition. However, in situations with high potential danger, participants confronted with an emergency alone or in the presence of another bystander were similarly likely to help the victim.

Mirror neurons and the phenomenology of intersubjectivity

The neurological discovery of mirror neurons is of eminent importance for the phenomenological theory of intersubjectivity. G. Rizzolatti and V. Gallese found in experiments with primates that a set of neurons in the premotor cortex represents the visually registered movements of another animal. The activity of these mirror neurons presents exactly the same pattern of activity as appears in the movement of one's own body. These findings may be extended to other cognitive and emotive functions in humans. I show how these neurological findings might be “translated” phenomenologically into our own experienced sensations, feelings and volitions.     

Reaction time task as unconditional stimulus

The present study was conducted to demonstrate classic conditioning in electrodermal (ED) and heart rate (HR) responses by using a nonaversive reaction time (RT) task as unconditional stimulus (US). Three groups of 12 subjects each were studied to test the efficacy of this US procedure by varying the essential components of the RT task-US between groups. Eight seconds differential delay conditioning was applied in each group. Simple geometric features (square, cross) displayed on a TV screen were used as CS+ and CS−. RT task consisted of a nonaversive tone (72 dBA, 1000 or 1200 Hz) and a motor response (pressing a button with the left index finger). Subjects were asked to respond as soon as the tone stimulus was presented. The three groups received different stimulus sequences during the 16-trial acquisition phase only. In one group (Group C1), CS+ was followed by a tone to which subjects were to respond, whereas CS− was not followed by a tone. Similarly, in a second group (Group H), CS+ was followed by a tone, whereas CS− was not; however, subjects of Group H (habituation group) were not required to respond to the tone. In a third group, (Group C2) CS+ was followed by a tone to which subjects were to respond, while CS− was followed by a different tone requiring no response. According to analysis of Group C1 data, differential conditioning was obtained in each response measure. Group H displayed habituation in each response measure obtained. In Group C2, differential conditioning was obtained in the second latency window of ED responses only. In all trials, first-interval anticipatory ED responses and HR responses did occur during acquisition, but were not differentiated with respect to the CS conditions. Although the results of Group C2 need further exploration, differential conditioning of HR and in all latency windows of ED responses was demonstrated by the use of a nonaversive RT task as US.
