Positive and negative intergroup contact and newcomer immigrants' psychological adjustment.

OBJECTIVES: The present research investigates the associations between immigrants' positive and negative contact with the majority group and their psychological well-being, as indicators of their psychosocial adjustment to the host society. Perceived personal discrimination and relative deprivation in comparison to the majority group are assessed as mediators of the associations between intergroup contact and psychological well-being. METHOD: We conducted a three-wave longitudinal study with newcomer African immigrants living in Italy (N = 240; 61.7% men) with age ranging from 18 to 40 years old. RESULTS: Evidence showed that, across three waves, immigrants' negative contact with Italian natives was longitudinally associated with lower well-being and positive intergroup contact. In turn, well-being was related to immigrants' lower perceptions of relative deprivation across waves. Positive contact with Italian natives was not significantly associated with immigrants' well-being, but it was associated with higher perceived relative deprivation, which was associated with lower well-being. CONCLUSIONS: Overall, the results provide insight into the links between differently valenced contact and the psychological well-being of newcomer immigrants. Furthermore, the findings address assumptions about the primacy of negative contact in undermining social attitudes and the important role of positive contact in promoting awareness of the disadvantaged group's situation.

Intergroup contact is reliably associated with reduced prejudice, even in the face of group threat and discrimination.

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) disadvantaged groups. We considered perceived intergroup threat and perceived discrimination as potential moderators of the effect of contact on prejudice. Two meta-analyses of correlational data from 34 studies (totaling 63,945 respondents-drawn from 67 subsamples across 19 countries) showed that contact was associated with decreased prejudice and increased out-group positivity, in cross-sectional and longitudinal designs, among advantaged and disadvantaged group members, and in both Western, Educated, Industrialized, Rich, and Democratic (WEIRD) and non-WEIRD contexts. Both perceived threat and perceived discrimination moderated the contact-attitude association, but in an unanticipated direction. Indeed, contact's beneficial effects were at least as strong among individuals high (r = .19) as among individuals low (r = .18) in perceived threat. Similarly, the effects of contact were at least as strong among those high (r = .23) as among those low (r = .20) in perceived discrimination. We conclude that contact is effective for promoting tolerant societies because it is effective even among subpopulations where achieving that goal might be most challenging.

Can Conspiracy Beliefs Be Beneficial? Longitudinal Linkages Between Conspiracy Beliefs, Anxiety, Uncertainty Aversion, and Existential Threat.

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 (NStudy 1 = 405, NStudy 2 = 1,012) to examine how conspiracy beliefs result from, and in turn influence, anxiety, uncertainty aversion, and existential threat. Random intercept cross-lagged panel analyses indicate that people who were, on average, more anxious, uncertainty averse, and existentially threatened held stronger conspiracy beliefs. Increases in conspiracy beliefs were either unrelated to changes in anxiety, uncertainty aversion, and existential threat (Study 2), or even predicted increases in these variables (Study 1). In both studies, increases in conspiracy beliefs predicted subsequent increases in conspiracy beliefs, suggesting a self-reinforcing circle. We conclude that conspiracy beliefs likely do not have beneficial consequences, but may even reinforce the negative experience of anxiety, uncertainty aversion, and existential threat.

Real-life outgroup exposure, self-reported outgroup contact and the other-race effect.

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 lower visual expertise. The present research investigates contact theories of the ORE, using self-report contact measures and objective measures of potential outgroup exposure (estimated from participants' residential location and from GPS tracking). Across six studies (total N = 2660), we observed that White American and White German participants displayed better memory for White faces compared with Black or Middle Eastern faces, whereas Black American participants displayed similarly equal or better memory for White compared with Black faces. We did not observe any relations between the ORE and objective measures of potential outgroup exposure. Only in Studies 2a and 2b, we observed very small correlations (rs = -.08 to .06) between 4 out of 30 contact measures and the ORE. We discuss methodological limitations and implications for theories of the ORE.

Warmth and competence perceptions of key protagonists are associated with containment measures during the COVID-19 pandemic: Evidence from 35 countries.

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 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 dimensions-warmth and competence-plays a crucial role in shaping pandemic-related behaviors. Firstly, when asked in an open question format, heads of state, physicians, and protest movements were universally identified as key protagonists across countries. Secondly, multiple-group confirmatory factor analyses revealed that warmth and competence perceptions of these and other protagonists differed significantly within and between countries. Thirdly, internal meta-analyses showed that warmth and competence perceptions of heads of state, physicians, and protest movements were associated with support and opposition intentions, containment and prevention behaviors, as well as vaccination uptake. Our results have important implications for designing effective interventions to motivate desirable health outcomes and coping with future health crises and other global challenges.

Antecedents of positive and negative intergroup contact: Evidence from a diary study.

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 positive and negative interactions of White British majority (N = 744) and Asian British minority people (N = 582) with members of the respective outgroup, with RWA, SDO, perceived ingroup norms, neighbourhood diversity and contextual deprivation. Results showed that for the majority group, ingroup norms in favour of intergroup contact were positively associated with positive intergroup encounters, whereas Right Wing Authoritarianism (RWA) was positively associated with negative intergroup contact. Neighbourhood diversity was positively associated with positive and negative intergroup encounters. Moreover, RWA moderated the relationship between neighbourhood diversity and both positive and negative contact of White British people. For the minority group, ingroup norms were positively associated with positive intergroup contact, and the relationship between ingroup norms and negative contact was moderated by SDO. Overall, different factors affect positive and negative intergroup contact of majority and minority groups. We discuss the implications of the findings for future research and interventions.

Dynamic contact effects: Individuals' positive and negative contact history influences intergroup contact effects in a behavioral game.

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 intergroup contact influences contact effects and how this dynamic change happens during specific instances of intergroup contact. A pilot study examined the psychological impact of a novel paradigm to assess intergroup contact using a behavioral game. We then conducted two studies, which allowed us to observe a sequence of up to 23 in- and outgroup interactions and their behavioral outcomes in a continuous prisoner's dilemma behavioral game (N = 116, 2,668 interactions; N = 89, 1,513 interactions). As expected, participants showed a clear ingroup bias in expectations and cooperation. Furthermore, the quality of contact history moderated contact effects. Specifically, intergroup contact following a positive history of intergroup contact had a stronger effect on intergroup expectations than contact following a negative history thereof. Findings are discussed in view of the importance of considering the valenced history of intergroup contact, as well as new research questions on intergroup contact that can be addressed with this novel contact paradigm.

Ethnic and gender-based prejudice towards medical doctors? The relationship between physicians' ethnicity, gender, and ratings on a physician rating website.

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 professionals. Results indicate that general practitioners (but not dentists or specialists) with non-German names are rated less favorably than general practitioners with German names. This effect did not vary across regional contexts with varying prosperity and diversity. Our analyses also revealed that female physicians are evaluated less positively than male physicians. Contrary to our assumptions, bias against female physicians was especially strong in medical sub-disciplines that are characterized by a high share of female physicians.

Status, relative deprivation, and moral devaluation of immigrants.

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 context, we predicted that immigration attitudes would be contingent on immigrant group status, with immigrants from low-status or poorer countries (Poland, India) more likely to be perceived as encroaching on the majority group's entitlements than those from high-status or richer countries (Germany, Australia). We further proposed moral devaluation (dehumanization and distrust) as a novel mechanism (over and above prejudice) underlying the conditional effects of relative deprivation on support for formal (anti-immigration policies) and informal (hate crime) means of immigrant exclusion. A pilot study (n = 245) and cross-sectional survey (n = 490) results supported our main prediction that status matters: participants felt more deprived relative to low- than high-status immigrants, and this predicted stronger support for anti-immigration policies both directly and through higher distrust (but not dehumanization). This research highlights the need to unpack the generic 'immigrant' category and study anti-immigration sentiment in terms of group status and moral devaluation.

Impact shock origin of diamonds in ureilite meteorites.

The origin of diamonds in ureilite meteorites is a timely topic in planetary geology as recent studies have proposed their formation at static pressures >20 GPa in a large planetary body, like diamonds formed deep within Earth's mantle. We investigated fragments of three diamond-bearing ureilites (two from the Almahata Sitta polymict ureilite and one from the NWA 7983 main group ureilite). In NWA 7983 we found an intimate association of large monocrystalline diamonds (up to at least 100 µm), nanodiamonds, nanographite, and nanometric grains of metallic iron, cohenite, troilite, and likely schreibersite. The diamonds show a striking texture pseudomorphing inferred original graphite laths. The silicates in NWA 7983 record a high degree of shock metamorphism. The coexistence of large monocrystalline diamonds and nanodiamonds in a highly shocked ureilite can be explained by catalyzed transformation from graphite during an impact shock event characterized by peak pressures possibly as low as 15 GPa for relatively long duration (on the order of 4 to 5 s). The formation of "large" (as opposed to nano) diamond crystals could have been enhanced by the catalytic effect of metallic Fe-Ni-C liquid coexisting with graphite during this shock event. We found no evidence that formation of micrometer(s)-sized diamonds or associated Fe-S-P phases in ureilites require high static pressures and long growth times, which makes it unlikely that any of the diamonds in ureilites formed in bodies as large as Mars or Mercury.

When good for business is not good enough: Effects of pro-diversity beliefs and instrumentality of diversity on intergroup attitudes.

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 detrimental to group functioning. Across four experiments, we studied the interplay between instrumentality-based pro-diversity beliefs, actual instrumentality of ethnic diversity, and outgroup attitudes. Our results do not reveal a robust interaction effect between instrumentality-based pro-diversity beliefs and actual instrumentality of diverse groups. Some evidence, however, supports the assumption that instrumentality-based pro-diversity beliefs yielded a weaker positive or even a negative effect on ethnic outgroup attitudes when ethnic diversity was perceived as non-instrumental (i.e., when diversity was perceived as having a negative impact on group functioning). Theoretical contributions, practical implications, and directions for future research are discussed.

The Bayesian causal inference model benefits from an informed prior to predict proprioceptive drift in the rubber foot illusion.

Bayesian cognitive modeling has become a prominent tool for the cognitive sciences aiming at a deeper understanding of the human mind and applications in cognitive systems, e.g., humanoid or wearable robotics. Such approaches can capture human behavior adequately with a focus on the crossmodal processing of sensory information. The rubber foot illusion is a paradigm in which such integration is relevant. After experimental stimulation, many participants perceive their real limb closer to an artificial replicate than it actually is. A measurable effect of this recalibration on localization is called the proprioceptive drift. We investigate whether the Bayesian causal inference model can estimate the proprioceptive drift observed in empirical studies. Moreover, we juxtapose two models employing informed prior distributions on limb location against an existing model assuming uniform prior distribution. The model involving empirically informed prior information yields better predictions of the proprioceptive drift regarding the rubber foot illusion when evaluated with separate experimental data. Contrary, the uniform model produces implausibly narrow position estimates that seem due to the precision ratio between the contributing sensory channels. We conclude that an informed prior on limb localization is a plausible and necessary modification to the Bayesian causal inference model when applied to limb illusions. Future research could overcome the remaining discrepancy between model predictions and empirical observation by investigating the changes in sensory precision as a function of distance between the eyes and respective limbs.

Indirect contact predicts direct contact: Longitudinal evidence and the mediating role of intergroup anxiety.

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: German adults, N = 560; Study 2: German, Dutch, and Swedish school students, N = 6,600; Study 3: Northern Irish children, N = 1,593; Study 4: Northern Irish adults, N = 404; Study 5: German adults, N = 735), we systematically examined this effect, and further tested the mediating role of intergroup anxiety in Studies 3 to 5. Cross-lagged models provided consistent evidence for the positive effect of indirect contact on future direct contact, whereas a reduction in intergroup anxiety mediates this effect in most models. Results highlight the importance of indirect contact, which has the potential to increase direct contact, and thus promote social cohesion in diverse contexts, over time.

Feel-Good Robotics: Requirements on Touch for Embodiment in Assistive Robotics.

The feeling of embodiment, i.e., experiencing the body as belonging to oneself and being able to integrate objects into one's bodily self-representation, is a key aspect of human self-consciousness and has been shown to importantly shape human cognition. An extension of such feelings toward robots has been argued as being crucial for assistive technologies aiming at restoring, extending, or simulating sensorimotor functions. Empirical and theoretical work illustrates the importance of sensory feedback for the feeling of embodiment and also immersion; we focus on the the perceptual level of touch and the role of tactile feedback in various assistive robotic devices. We critically review how different facets of tactile perception in humans, i.e., affective, social, and self-touch, might influence embodiment. This is particularly important as current assistive robotic devices - such as prostheses, orthoses, exoskeletons, and devices for teleoperation-often limit touch low-density and spatially constrained haptic feedback, i.e., the mere touch sensation linked to an action. Here, we analyze, discuss, and propose how and to what degree tactile feedback might increase the embodiment of certain robotic devices, e.g., prostheses, and the feeling of immersion in human-robot interaction, e.g., in teleoperation. Based on recent findings from cognitive psychology on interactive processes between touch and embodiment, we discuss technical solutions for specific applications, which might be used to enhance embodiment, and facilitate the study of how embodiment might alter human-robot interactions. We postulate that high-density and large surface sensing and stimulation are required to foster embodiment of such assistive devices.

Intergroup Contact and Social Change: Implications of Negative and Positive Contact for Collective Action in Advantaged and Disadvantaged Groups.

Previous research has shown that (a) positive intergroup contact with an advantaged group can discourage collective action among disadvantaged-group members and (b) 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 positive intergroup contact. Study 1 ( n = 482) found that negative but not positive contact with heterosexual people was associated with sexual-minority students' engagement in collective action (via group identification and perceived discrimination). Among heterosexual students, positive and negative contacts were associated with, respectively, more and less LGB (lesbian, gay, bisexual) activism. Study 2 ( N = 1,469) found that only negative contact (via perceived discrimination) predicted LGBT (lesbian, gay, bisexual, and transgender) students' collective action intentions longitudinally while only positive contact predicted heterosexual/cisgender students' LGBT activism. Implications for the relationship between intergroup contact, collective action, and social change are discussed.

The "Wallpaper Effect" Revisited: Divergent Findings on the Effects of Intergroup Contact on Attitudes in Diverse Versus Nondiverse Contexts.

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 measures, and involving different minority versus majority groups. Using multilevel cross-level interaction models, we considered whether effects of contact on outgroup attitudes were moderated by relative outgroup size. Results failed to replicate the previously reported findings, revealing, by and large, nonsignificant cross-level moderation effects; instead, we witnessed consistent positive contact effects on attitudes. Findings are discussed against the backdrop of recent research on the consequences of diversity, as well as context-based considerations regarding minority versus majority constellations. We also discuss some exceptions to our findings that emerged for some respondent groups and contexts across the five studies.

(Bad) Feelings about Meeting Them? Episodic and Chronic Intergroup Emotions Associated with Positive and Negative Intergroup Contact As Predictors of Intergroup Behavior.

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 context of intergroup relations between non-immigrant Germans and foreigners living in Germany. In Study 1, we showed that positive and negative contact are related to specific episodic intergroup emotions (i.e., anger, fear and happiness). Results of Study 2 indicate an indirect effect of episodic intergroup emotions encountered during contact experiences on specific behavioral tendencies directed at outgroup members via more chronic situation-independent intergroup emotions. As expected, anger predicted approaching (discriminatory) behavioral tendencies (i.e., aggression) while fear predicted avoidance. The results extend the existing literature on intergroup contact and emotions by addressing positive and negative contact simultaneously and differentiating between situation-specific episodic and chronic intergroup emotions in predicting discriminatory behavioral tendencies.

Variable aldehyde dehydrogenase activity and effects on chemosensitivity of primitive human leukemic cells.

Aldehyde dehydrogenase (ALDH) activity is an established feature of primitive normal human hematopoietic cells, in which it has been associated with a high expression of the 1A1 isoform of ALDH. High ALDH 1A1 activity has been reported to also characterize cells that propagate malignant populations arising in other tissues, but the regulation and basis of ALDH activity in primary human leukemic cells has not been well studied. We obtained samples from patients with newly diagnosed acute myeloid leukemia (AML; n = 21) and chronic myeloid leukemia (CML; n = 8) and analyzed different phenotypically and functionally defined subsets for their ALDH activity using the ALDEFLUOR® kit and expression of the ALDH1A1 gene. We detected cells with high ALDH activity (ALDHpos) in all samples from AML and CML patients. These were consistently enriched in the CD34+ population of these samples, but typically not in the CD34+CD38- subset. Leukemic cells with direct clonogenic activity in vitro or those able to repopulate the bone marrow of sublethally irradiated non-obese diabetic (NOD)/severe combined immunodeficiency (SCID) mice were both ALDHpos and ALDHneg. Interestingly, ALDH1A1 transcripts were highest in the ALDHneg leukemic cells and, in studies with leukemic cell lines, exposure to an inhibitor of ALDH activity variably affected sensitivity to daunorubicin. Cells with high ALDH activity are commonly found within the CD34+ population of primary human leukemic cells but, unlike in normal hematopoietic tissues, do not selectively or consistently comprise those with proliferative potential or other distinct functional properties.
