The present study focuses on two aspects of this threshold: it investigates processes, which may influence the absence of ingroup favouritism in the negative domain, and it tests 'aggravating' variables, which seem to be suficient to elicit ingroup favouritism even in the negative domain. Results show that ingroup favouritism occurred within the negative domain when several aggravating conditions were included, namely high salience of size- and status- similarity between groups and high ingroup identification. Furthermore, subjects under minimal conditions tended to overestimate relative size as well as relative status of their ingroup. The perception of group members to belong to a high status majority is interpreted as a sufficient condition counteracting tendencies towards ingroup favouritism within the negative domain.}, language = {en} } @article{SchruijerBlanzMummendeyetal., author = {Schruijer, Sandra and Blanz, Mathias and Mummendey, Am{\´e}lie and Tedeschi, Jim and Banfai, Beata and Dittmar, Helga and Kleibaumh{\"u}ter, Petra and Mahjoub, Abdelwahab and Mandrosz-Wroblewska, Joanna and Molinari, Luisa and Petillon, Xavier}, title = {The group-serving bias in evaluating and explaining harmful behavior}, series = {The Journal of Social Psychology}, volume = {134}, journal = {The Journal of Social Psychology}, number = {1}, doi = {https://doi.org/10.1080/00224545.1994.9710882}, pages = {47 -- 53}, abstract = {Group-serving biases in evaluating and explaining harmful behavior were investigated.

The model is strongly related to the accessibility×fit formulation by Bruner (1957) and to Oakes' (1987) functional perspective on category salience. The results of an experimental series using the 'Who said what?' paradigm are presented, which examined several hypotheses derived from the model. In Study I it was shown that the salience of a social categorization with high chronic accessibility (sex categorization) was related to perceptions of issue relevance (normative fit) and intercategory differences (meta-contrast ratio). Furthermore, in line with the salience model measures to increase the situational accessibility, (i.e. a priming procedure) of categorizations with low chronic accessibility (educational group and home town categorizations) failed to affect category salience as long as participants perceived no comparative and normative fit of these categorizations (Study II). Under conditions where comparative fit of these categorizations was perceived, however, the priming procedure successfully enhanced category salience (Studies II and III). Results are largely consistent with the hypotheses derived from the salience model and support Oakes' functional approach to category salience. Finally, the complex interrelation between situational accessibility and perceived fit will be discussed.}, language = {en} } @article{BlanzMummendeyMielkeetal., author = {Blanz, Mathias and Mummendey, Am{\´e}lie and Mielke, Rosemarie and Klink, Andreas}, title = {Wechselseitige Differenzierung zwischen sozialen Gruppen: Ein Vorhersagemodell der Theorie der sozialen Identit{\"a}t}, series = {Zeitschrift f{\"u}r Sozialpsychologie}, volume = {29}, journal = {Zeitschrift f{\"u}r Sozialpsychologie}, number = {3}, pages = {239 -- 259}, abstract = {Hypotheses derived from social identity theory (Tajfel, 1978) were tested by investigating intergroup differentiation between 2 natural groups.

The more group members favored their IG over the out-group (OG), the more they emphasized the relative relevance of the pertinent comparative dimension for their IG. Furthermore, a predictive model of intergroup differentiation was tested in which IG favoritism was set to be a function of the perceived stability and legitimacy of the status-difference as well as the perceived permeability of group boundaries. The results showed that members of the low status group favored their IG on the status-unrelated dimension the more the intergroup structure was perceived as being stable, illegitimate, and impermeable and the more they identified themselves with their East-German IG. On the other hand, members of the high status group favored their IG on the status related dimension the more legitimate they perceived the status-difference between both groups.}, language = {de} } @article{BlanzMummendeyMielkeetal., author = {Blanz, Mathias and Mummendey, Am{\´e}lie and Mielke, Rosemarie and Klink, Andreas}, title = {Responding to negative social identity: A taxonomy of identity management strategies}, series = {European Journal of Social Psychology}, volume = {28}, journal = {European Journal of Social Psychology}, number = {5}, doi = {https://doi.org/10.1002/(SICI)1099-0992(199809/10)28:5\%3C697::AID-EJSP889\%3E3.0.CO;2-\%23}, pages = {697 -- 729}, abstract = {Taken from literature on social identity theory and social comparison theory, 12 strategies of identity management were identified as possible responses to negative social identity. A taxonomy with two orthogonal axes is proposed as theoretical organization of these diverse strategies. While the first axis considers responses as being either individual or collective, the second axis refers to the distinction between behaviours and cognitions. It is assumed that the German unification process implied a lower status position of East Germans relative to West Germans on relevant comparison dimensions, and that East Germans have to deal with this threat to their identity. Hence, data of an East German sample are used to empirically systematize identity management strategies, and, thus, to test the proposed taxonomy. Results support the expected four-factor solution only for those strategies taken from social identity theory, while the responses derived from social comparison research build a fifth factor. In addition, the empirical assignments of strategies to cells of the taxonomy are only partly in line with the expected pattern. The empirical findings suggest some clarification and modifications of the proposed response taxonomy. The most important refers to a re-interpretation of the taxonomy's first axis, which now differentiates between responses according to the specific changes of the comparison parameters they imply.}, language = {en} } @article{Blanz, author = {Blanz, Mathias}, title = {Soziale Kategorisierung und soziale Diskriminierung bei Exklusion versus Inklusion der eigenen Person}, series = {Zeitschrift f{\"u}r Sozialpsychologie}, volume = {28}, journal = {Zeitschrift f{\"u}r Sozialpsychologie}, number = {5}, pages = {265 -- 279}, abstract = {Proposes a theoretical model of antecedents of the salience of social categorizations that is strongly related to the work of J.

Second, the study examined the relationship between social categorization on the one hand and social discrimination on the other. The results show that under otherwise equal conditions an inclusive social categorization is more salient than an exclusive one.
