Identity affirmation and social movement support

It is argued that the power of collective identification to mobilize people for collective action such as social movement support derives at least partly from processes of identity affirmation. The hypothesized identity‐affirming function of social movement support is tested in two laboratory experiments which revolve around collective identity as a supporter of the peace movement. In Experiment 1, we predicted and found that people who strongly identified with the peace movement showed more movement support (i.e. made more monetary donations to the peace movement) under conditions of uncertain as opposed to certain possession of identity as a movement supporter. In Experiment 2, we replicated this finding, but also found, in accordance with the notion of substitution, that the mobilizing effect of uncertain collective‐identity possession was undermined when an identity symbol was available that could function as a surrogate for more costly identity‐affirming behaviour. Further conceptual and social implications of the identity‐affirming function of social movement support are discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

Sectors and strategies of global communications regulation

As the global communication network matures, the systems and procedures for regulating the growing network and its use are being challenged. The general proliferation of services or the specific demand for electronic transactions require guidance and control which the market alone cannot supply. Meanwhile, traditional regulatory regimes remain far from global or coherent. This article distinguishes between coordination and regulation to clarify areas where government intervention is unnecessary and where indispensable. It explores the current patchwork of regulatory approaches, reviews different regulatory areas and strategies, identifies trends, and highlights problem areas particular to electronic commerce and third party protection. His research covers areas such as Access Problems in the Multimedia Age, Legal Framework of Data Protection and Data Security, and Regulation of “Old” and “New” Media. His current research is focused on the interaction of technical and institutional innovations and on the evolution, development, and governance of the Internet.

Intragroup differentiation in terms of ingroup and outgroup attributes

An experiment (n = 36) was conducted to test the hypothesis that attribute typicality moderates intragroup differentiation. The predicted reversal from perceived relative ingroup homogeneity on typical ingroup attributes to perceived relative outgroup homogeneity on typical outgroup attributes was confirmed for both homogeneity measures (standard deviation and probability of differentiation). But the ingroup homogeneity effects were more reliable than the outgroup homogeneity effects. Relative ingroup size (minority versus majority) was included in the experimental design as a between-subjects factor but did not qualify the reversal of perceived relative homogeneity.     

Consumers' Affective Response to Delays at Different Phases of a Service Delivery1

A field experiment was conducted in an educational setting to investigate affective reactions occurring at different phases of the delivery of a service. An eight-minute delay caused more negative affective reactions when it occurred either before the service started (preprocess) or after the service had terminated (postprocess) than when it occurred in the middle of the service encounter (in-process). No differences were observed for positive affect. Field theory is proposed as a theoretical framework to account for the results, and practical applications for addressing the social problem of structuring waiting environments are discussed.     

A closer look at the complex structure of gender stereotypes

In the present paper an experimental design is introduced for the analysis of the conceptual categories used by subjects when stereotyping males and females. Subjects were asked to name as many familiar types of women and men as they could think of, and describe them in terms of various characteristic properties (e.g., traits, attitudes, interests, skills, and demographic features). The most frequently mentioned types were then sorted by a second sample according to their perceived similarity. Finally, a third group of subjects categorized the initial set of properties in terms of their relevance to either male or female types. Clustering and scaling analyses yielded a clear cut picture of the cognitive ordering principles underlying gender stereotypes. Distinct property clusters were found for the female and male types, underlining the important role of gender stereotypes in the knowledge base of the subjects.The authors would like to thank Kay Deaux for helpful comments on an earlier draft.     

Involvement of alpha-bungarotoxin-sensitive nicotinic receptors in long-term memory formation in the honeybee (Apis mellifera)

In the honeybee Apis mellifera, multiple-trial olfactory conditioning of the proboscis extension response specifically leads to long-term memory (LTM) which can be retrieved more than 24 h after learning. We studied the involvement of nicotinic acetylcholine receptors in the establishment of LTM by injecting the nicotinic antagonists mecamylamine (1 mM), alpha-bungarotoxin (alpha-BGT, 0.1 mM) or methyllycaconitine (MLA, 0.1 mM) into the brain through the median ocellus 20 min before or 20 min after multiple-trial learning. The retention tests were performed 1, 3, and 24 h after learning. Pre-training injections of mecamylamine induced a lower performance during conditioning but had no effect on LTM formation. Post-training injections of mecamylamine did not affect honeybees' performances. Pre-training injections of MLA or post-training injection of alpha-BGT specifically induced LTM impairment whereas acquisition as well as memory retrieval tested 1 or 3 h after learning was normal. This indicates that brain injections of alpha-BGT and MLA did not interfere with learning or medium-term memory. Rather, these blockers affect the LTM. To explain these results, we advance the hypothesis that honeybee alpha-BGT-sensitive acetylcholine receptors are also sensitive to MLA. These receptors could be essential for triggering intracellular mechanisms involved in LTM. By contrast, medium-term memory is not dependent upon these receptors but is affected by mecamylamine.     

On being more than just a part of the whole: Regional identity and social distinctiveness

This article reports the results of a questionnaire study that examined the relationship between regional identification and perceptual accentuation of ingroup distinctiveness in a natural field setting. Respondents were male inhabitants of the Saarland which is a small German state. Half the respondents were members of the leading political party of the Saarland, while the other respondents were members of the major opposition party. As expected, the former showed more pronounced regional identification than the latter. Our main prediction was that a higher level of regional identification would be accompanied by stronger accentuation of positive distinctiveness of the regional ingroup relative to the national ingroup. The prediction was confirmed, both in terms of intergroup differentiation and perceived group homogeneity. Additional results suggest that, depending on the level of social identification, perceived group homogeneity may be either positively or negatively related to familiarity with the ingroup. Finally, we discuss the applicability of social identity theory to social contexts comprising differentially inclusive ingroups instead of mutually exclusive ingroups and outgroups.     

The perception of ingroup and outgroup homogeneity: On the confounding of group size,level of abstractness and frame of reference. A reply to Bartsch and Judd

In this reply, I criticize Bartsch and Judd's (1993) article on several grounds. First, they under-utilize the efforts undertaken in prior work to rule out the possibility of an inverse relation between group size and perceived group homogeneity as an alternative explanation of the observed ingroup homogeneity effect. Secondly, Bartsch and Judd's design doubles and thus aggravates the confounding problem. By trying to avoid the target group size confound, they end up with two other confounds involving level of abstractness and frame of reference. Finally, I criticize Bartsch and Judd's methodological advice to avoid within-subjects comparisons of ingroup and outgroup homogeneity in minority–majority contexts. Quite on the contrary, I highlight the socialpsychological significance of these comparisons.     

The influence of stereotypes on decisions to shoot

Using a videogame to simulate encounters with potentially hostile targets, three studies tested a model in which racial bias in shoot/don't-shoot decisions reflects accessibility of the stereotype linking Blacks to danger. Study 1 experimentally manipulated the race-danger association by asking participants to read newspaper stories about Black (vs. White) criminals. As predicted, exposure to stories concerning Black criminals increased bias in the decision to shoot. Studies 2 and 3 manipulated the number of White and Black targets with and without guns in the context of the videogame itself. As predicted, frequent presentation of stereotypic (vs. counterstereotypic) targets exacerbated bias (Study 2) and—consistent with our process account—rendered stereotypes more accessible (Study 3).
