Issmer, C. & Wagner, U. (2014 in press). Perceived marginalization and aggression: A longitudinal study with low-educated adolescents. British Journal of Social Psychology.Abstract
Social exclusion can evoke aggression. In the past two decades, research has demonstrated this effect both for interpersonal and societal forms of exclusion. In addition, recent violent uprisings, like the London riots in August 2011, have been linked to social exclusion in the media. However, so far there is a lack of longitudinal studies which examine the aggression-enhancing effect of societal-level exclusion (i.e. marginalization) in disadvantaged groups. This research investigates the impact of perceived marginalization on aggression in a sample of N = 181 adolescents with a low educational background by means of a two-wave longitudinal study. The results of structural equation analyses are consistent with the hypothesis that perceived marginalization enhances aggression, and that this effect is mediated by the extent of negative societal meta-stereotypes. Furthermore, the reverse path from aggression to perceptions of marginalization is also significant. We discuss the implications of these findings and highlight practical consequences.

The term foreigners is often used in prejudice research to analyze prejudice towards immigrants, but it us not specified which groups respondents have in mind. In the present study, we analyzed the content of the term foreigner and its impact on prejudice towards foreigners in a German national probability sample (N = 1,763). Results indicated that most respondents think of people with a Turkish migration background, but regional differences between East and West Germany occurred. In addition, the different individual meanings connected with the term foreigners go along with different levels of prejudice against foreigners: Differences in prejudice towards foreigners between East and West Germany are partially due to different groups associated with the term foreigner. Theoretical and practical implications for quantitative prejudice research are discussed.

We assessed evidence for a contextual effect of positive intergroup contact, whereby the effect of intergroup contact between social contexts (the between-level effect) on outgroup prejudice is greater than the effect of individual-level contact within contexts (the within-level effect). Across seven large-scale surveys (five cross-sectional and two longitudinal), using multilevel analyses, we found a reliable contextual effect. This effect was found in multiple countries, operationalizing contact at multiple levels (regions, districts, and neighborhoods), and with and without controlling for a range of demographic and context variables. In four studies (three cross-sectional and one longitudinal), we showed that the association between context-level contact and prejudice was largely mediated by more tolerant norms. In social contexts where positive contact with outgroups was more commonplace, norms supported such positive interactions between members of different groups. Thus, positive contact reduces prejudice on a macrolevel, whereby people are influenced by the behavior of others in their social context, not merely on a microscale, via individuals' direct experience of positive contact with outgroup members. These findings reinforce the view that contact has a significant role to play in prejudice reduction, and has great policy potential as a means to improve intergroup relations, because it can simultaneously impact large numbers of people.
