Significance Although mixed social environments can provoke conflict, where this diversity promotes positive intergroup contact, prejudice is reduced. Seven multilevel studies demonstrate that the benefits of intergroup contact are broader than previously thought. Contact not only changes attitudes for individuals experiencing direct positive inter...

Although the effects of direct and indirect forms of contact on intergroup relations are well documented, little is known about their longitudinal co-development. Based on the social-psychological literature, we hypothesize that indirect contact predicts future direct contact by reducing intergroup anxiety. Across five longitudinal studies (Study 1...

Positive contact between members of different groups reduces prejudice and increases cooperation, findings known as intergroup contact effects. Yet in real-world settings not only positive, but also negative intergroup contact occurs, which have opposing effects. To date little is known about whether and how an individual’s valenced history of inte...

Intergroup contact provides a reliable means of reducing prejudice. Yet, critics suggested that its efficacy is undermined, even eliminated, under certain conditions. Specifically, contact may be ineffective in the face of threat, especially to (historically) advantaged groups, and discrimination, experienced especially by (historically) disadvanta...

It is crucial to understand why people comply with measures to contain viruses and their effects during pandemics. We provide evidence from 35 countries ( N total = 12,553) from 6 continents during the COVID-19 pandemic (between 2021 and 2022) obtained via cross-sectional surveys that the social perception of key protagonists on two basic dimension...

Constructing interactive web apps has become more accessible for instructors, for example, by using the R package Shiny. Here we explored learners' preferences and the efficiency of interactive simulations versus static pictures in acquiring statistics knowledge of Cohen's d and standard normal distribution. Results revealed that students' spontane...

People are better at recognizing faces from their own racial or ethnic group compared with faces from other racial or ethnic groups, known as the other-'race' effect (ORE). Several theories of the ORE assume that memory for other-race faces is impaired because people have less contact with members of other racial or ethnic groups, resulting in lowe...

It is crucial to understand why people comply with measures to contain viruses and their effects during pandemics. We provide evidence from 35 countries (Ntotal = 12,553) from six continents during the COVID-19 pandemic that the social perception of key protagonists on two basic dimensions of social perception – warmth and competence – played a cru...

Statistics is not the subject most psychology students are feverishly looking forward to. Fears and doubts about its relevance are quite common. This is especially pronounced at our institution, a large distance-teaching university with highly heterogeneous students. We recognized three clusters of students that might need special support: (1) stud...

In our current globalised, multicultural world, understanding antecedents of reciprocal interactions between native people and people of immigrant background is a major issue, because intergroup contact plays a crucial role in building inclusive societies. In this vein, using daily diary data, we examined the relation between the number of daily po...

Das Lehrangebot der psychologischen Methodenlehre im Studiengang B.Sc. Psychologie an der FernUniversität in Hagen wurde in den vergangenen Semestern intensiv weiterentwickelt. Für die praktischen Anteile des Statistik-Moduls wird die Statistiksoftware R gelehrt und verwendet. Im Rahmen des Projekts "DIStaM" wird die Lehre weiter digitalisiert. Tec...

Research suggests that conspiracy beliefs are adopted because they promise to reduce anxiety, uncertainty, and threat. However, little research has investigated whether conspiracy beliefs actually fulfill these promises. We conducted two longitudinal studies ( N Study 1 = 405, N Study 2 = 1,012) to examine how conspiracy beliefs result from, and in...

Immigration has been a prominent political issue for decades, but particularly so with rising national populism. To understand current anti‐immigration opinion, we turn to the concept of relative deprivation, which, we argue, is fundamentally about entitlement and is at the heart of popular backlash against immigration. Examining the United Kingdom...

We investigated manifestations of ethnic and gender-based prejudice in a rather understudied high-status environment, that is we studied biased ratings of physicians with a migration background and female physicians. In a preregistered, archival study, we analyzed ratings of more than 140,000 physicians on a German rating website for medical profes...

Social identity exploration is a process whereby individuals actively seek information about their group membership and show efforts to understand its meaning. Developmental theory argues that exploration-based ingroup commitment is the basis for outgroup positivity. We tested this notion in relation to national identity and attitudes towards immig...

Intergroup contact is an established pathway to improve intergroup relations. Research has long focused on mainly positive intergroup contact and its capability to improve intergroup relations. Yet, if members of different groups meet, they will not only make positive, but possibly also negative intergroup contact experiences. Recent research consi...

Replication studies in psychological science sometimes fail to reproduce prior findings. If these studies use methods that are unfaithful to the original study or ineffective in eliciting the phenomenon of interest, then a failure to replicate may be a failure of the protocol rather than a challenge to the original finding. Formal pre-data-collecti...

Compared to the impressive amount of research on consequences of intergroup contact, relatively little work has been devoted to predictors of intergroup contact. Although opportunities for intergroup contact are constantly growing in modern diverse societies, these contact opportunities are not necessarily exploited. In the present review article,...

As part of the Many Labs 5 project, we ran a replication of van Dijk, van Kleef, Steinel, and van Beest’s (2008) study examining the effect of emotions in negotiations. They reported that when the consequences of rejection were low, subjects offered fewer chips to angry bargaining partners than to happy partners. We ran this replication under three...

We challenge the common interpretation of targets’ immediate confrontation in reaction todiscrimination as self-serving behavior and propose different underlying motivations for this phenomenon. In five online scenario studies (Noverall = 1,447), we demonstrate across different samples and contexts that targets indicate a distinct pursuit of the fo...

Instrumentality-based pro-diversity beliefs (i.e., beliefs that diverse groups outperform homogenous groups in terms of group functioning) have been shown to improve intergroup attitudes. However, such valuing of diversity due to its expected instrumentality holds the risk that outgroups may be devalued in situations when diversity ends up being de...

As part of the Many Labs 5 project, we ran a replication of Van Dijk, Van Kleef, Steinel, & Van Beest’s (2008) study “A social functional approach to emotions in bargaining: When communicating anger pays and when it backfires,” which examined the effect of emotions in negotiations. Van Dijk et al. (2008) report that when the consequences of rejecti...

Bringing members of different social groups into contact is thought to be as one of the most promising approaches for improving intergroup relations. Indeed, a plethora of studies has shown that this intergroup contact is an effective means not only to reduce mutual prejudice but also to increase trust and forgiveness. In this chapter, we will firs...

In general, diversity beliefs are beliefs about the instrumentality of diversity for the functioning of groups. Focusing on a societal level, recent social-psychological research addressed pro-diversity beliefs as individuals’ beliefs that diversity is beneficial for the progress of society. Despite the growing interest in societal pro-diversity be...

This report in German language gives an overview of 10 years of distance education programs in psychology at the FernUniversität in Hagen, Germany's only public distance education university. It will be published in Psychologische Rundschau (2018), 69 (2), 1–5.

A science of groups needs to take different levels of analysis into account since only multilevel perspectives provide a full and realistic picture of processes within and between social groups. A multilevel perspective, however, requires appropriate statistical models. Conventional multilevel regression models suffer from a number of limitations....

Based on two cross-sectional probability samples (Study 1: N = 1,382, Study 2: N = 1,587), we studied the interplay between positive and negative intergroup contact, different types of intergroup emotions (i.e., episodic intergroup emotions encountered during contact and more general chronic intergroup emotions), and outgroup behavior in the contex...

This article reexamines the so-called “wallpaper effect” of intergroup contact, which contends that for minority group members living in areas more densely populated by majority group members, intergroup contact fails to reduce prejudice. We tested this claim in five studies, using data from five countries, two types of contexts, a range of measure...

We examined the concepts and emotions people associate with their national flag, and how these associations are related to nationalism and patriotism across 11 countries. Factor analyses indicated that the structures of associations differed across countries in ways that reflect their idiosyncratic historical developments. Positive emotions and ega...

Previous research has shown that (1) positive intergroup contact with an advantaged group can discourage collective action among disadvantaged-group members and (2) positive intergroup contact can encourage advantaged-group members to take action on behalf of disadvantaged outgroups. Two studies investigated the effects of negative as well as posit...

While some research suggests that ethnic and cultural diversity hinders societal cohesion, other studies show that it promotes intergroup contact opportunities, which, if exploited, help to overcome intergroup prejudice. Recently, however, intergroup contact theory has been criticized for neglecting the wider social context as well as for ignoring...

Much social psychological research is concerned with the question whether and how behavior changes because of a “treatment” (e.g., a situation that triggers a psychological reaction). One easy way to investigate such changes would be to analyze intraindividual differences before (Time 1) and after the treatment (Time 2). Interestingly, many scholar...

The distinction of different test anxiety reactions (e.g., worry, emotionality) is well established. Recently, additional relevance has been given to school-subject-specific test anxiety factors. The present study explored a further aspect concerning the structure of test anxiety experiences, specifically oral versus written examination modes. A qu...

Allport’s (1954) ‘contact hypothesis’ proposed that intergroup contact is a powerful means for improving intergroup attitudes. Subsequent theory and research has developed this hypothesis into a full-blown theory that makes precise predictions about the effects of different types of contact on mainly attitudinal outcomes, and how and when those eff...

We sought to identify the mechanisms that cause strongly fused individuals (those who have a powerful, visceral feeling of oneness with the group) to make extreme sacrifices for their group. A large multinational study revealed a widespread tendency for fused individuals to endorse making extreme sacrifices for their country. Nevertheless, when ask...

Zahlreiche Studien belegen die Relevanz von Emotionsregulationskompetenzen für die psychische Gesundheit. Problematisch ist jedoch, dass viele dieser Studien Selbsteinschätzungsmaße verwenden, die Kompetenzen im Umgang mit Emotionen oder Stimmungen im Allgemeinen zu erfassen suchen. Dadurch bleibt unklar, auf welche Emotionen sich die Probanden bei...

The effect of the intergroup climate on acculturation preferences among host-majority and immigrant group members has been long acknowledged in the acculturation literature. Only recently, however, research has started to directly examine the effect of the intergroup climate on acculturation preferences. In the present research, we aimed to contrib...

The present study investigated cardiac threat appraisal and its association with depression after first myocardial infarction (MI). A semi-structured interview allowing for DSM-IV-axis I diagnoses was administered to 36 patients after first MI. Patients completed self-reports 5-15 days after the MI (time 1), 6-8 weeks later (time 2), and again 6 mo...

Public opposition to antiracism laws—an expression of prejudice toward immigrants—is widespread in Switzerland as well as in other European countries. Using data from the European Social Survey 2002 (N = 1,711), the present study examined across Swiss municipalities individual and contextual predictors of opposition to such laws and of two well-est...

A number of cross-sectional studies have demonstrated a significant co-variation of patriotism and nationalism with prejudice against immigrants. This study examines the causal relationship between the three variables among 551 adult German respondents without migration background. Employing a longitudinal cross-lagged design with two measurements...

The present research examined effects of exposure to the German flag on outgroup prejudice in Germany. In agreement with social identity theory, we demonstrated that exposure to the German flag increased outgroup prejudice among highly nationalistic German respondents. This finding seems to contradict prior research illustrating that exposure to th...

An integrated personality and social psychology needs to take into account different levels of analysis by definition. In both disciplines, it is widely accepted that personality and the social context affects social behavior and that social behavior, in turn, also informs us about personality. The challenge for an integrated personality and social...

Social scientists have long recognized that national identification can enhance anti-immigrant prejudice. Most studies in this field, however, have tended to focus on individual-level relations only. Although this line of research has much to offer (e.g., Blank and Schmidt, 2003), we suggest that an even more comprehensive understanding of how nati...

Intergroup contact is among the most effective ways to improve intergroup attitudes. Research examining whether the effects of contact are contingent on individual differences is limited, however. The authors test a dual process model perspective of individual differences in contact and prejudice. Their model predicts that intergroup contact should...

Why do societal crises often lead to intergroup conflict? We propose that the interplay of unspecific threat and causal attributions differentially predicts increases in ethnic prejudice and anti-Semitism. We tested this hypothesis in the context of the 2008 financial crisis. The results of Study 1 (N = 890) demonstrated on the basis of representat...

The present research examined the hypothesis that participation in radical, but not moderate, action results in disidentification from the broader in-group. Study 1 (N = 98) was a longitudinal study conducted in the context of student protests against tuition fees in Germany and confirmed that participation in radical collective action results in d...

Intergroup contact (especially cross-group friendship) is firmly established as a powerful strategy for combating group-based prejudice (Pettigrew & Tropp, 2006). Great advances have been made in understanding how contact reduces prejudice (Brown & Hewstone, 2005), highlighting the importance of affective mediators (Pettigrew & Tropp, 2008). The pr...

A recent model of collective action distinguishes 2 distinct pathways: an emotional pathway whereby anger in response to injustice motivates action and an efficacy pathway where the belief that issues can be solved collectively increases the likelihood that group members take action (van Zomeren, Spears, Fischer, & Leach, 2004). Research supporting...

Recent advances in intergroup contact theory and research are reviewed. A meta-analysis with 515 studies and more than 250,000 subjects demonstrates that intergroup contact typically reduces prejudice (mean r = −.21). Allport's original conditions for optimal contact – equal status, common goals, no intergroup competition, and authority sanction –...

Zusammenfassung: Zur Erfassung der psychischen Gesundheit von Migranten im Vergleich zu Deutschen sind Untersuchungen in der Allgemeinbevolkerung zentral. Fur diesen Ansatz hat sich die Verwendung des Depressivitats- und des Somatisierungsmoduls des Patient Health Questionnaire (PHQ-9, PHQ-15) bewahrt. Es ist jedoch unklar, ob diese Module bei Migr...

Cross-group friendships (the most effective form of direct contact) and extended contact (i.e., knowing ingroup members who have outgroup friends) constitute two of the most important means of improving outgroup attitudes. Using cross-sectional and longitudinal samples from different intergroup contexts, this research demonstrates that extended con...

Two cross-sectional survey studies among majority-status White and minority-status Coloured high school students in South Africa explored the effects of crossgroup friendships on prejudice, and the affective processes (intergroup anxiety in Study 1, and intergroup anxiety and affective empathy in Study 2) underlying these effects with respect to tw...

Are small or large outgroup populations more closely related to an ingroup's prejudice? This paper addresses this question with national probability survey data from Germany focused on resident foreigners. Two interlocking processes underlie the complex relationship between population proportions and prejudice. Typically, larger outgroup population...

Anti-immigration bias Migrants, especially those who cross national state boarders, become targets of political debates, often involving derogation of immigrants, and both discrimination and violence against them. This chapter starts with a brief look at the history of bias against immigrants and the history of the accompanying social psychological...

This article extends research on leader procedural fairness as well as the social identity model of leadership effectiveness (SIMOL) by demonstrating that leader prototypicality can act as a substitute for procedural fairness. Although procedural fairness in general and voice in particular have been found to have a robust positive influence on lead...

Using data from a 2006 opinion survey of British Muslims (N = 1000), this study examined the role of importance of Muslim and British identity as proximal predictors of whether respondents viewed the 2005 London bombings as justified. We further explored the extent to which religious and national identity and support for terrorism were predicted by...

Übergänge sind ein zentrales Merkmal des mitteleuropäischen Schulsystems und sind wichtige Phasen für das Kind. Bei gegliederten Schulsystemen wird der Eintritt in die Sekundarstufe I besonders bedeutsam, weil mit der Zuweisung zu einem der Schultypen implizit auch die Zuteilung von Bildungschancen verbunden ist. Für die Zuweisung ist die Lehreremp...

This article analyses the relationship of ethnic prejudice and discriminatory behavioral intentions in Germany. We utilize two representative surveys conducted in 2002 and 2004 (N= 2,722 and 1,383, respectively) as well as a longitudinal study with three annual measurement points (2002–2004; N= 825). Results show that prejudice is substantially cor...
