"You Little Creep": Evidence of Blatant Dehumanization of Short Groups
Physical cues influence social judgments of others. For example, shorter individuals are evaluated less positively than taller individuals. Here, we demonstrate that height also impacts one of the most consequential intergroup judgments - attributions of humanity - and explore whether this effect is modulated by the tendency to value hierarchy maintenance. In Study 1, the shorter participants perceived a range of out-groups to be, the more they dehumanized them, and this tended to be particularly pronounced among those scoring high on social dominance orientation (SDO). In Study 2, participants dehumanized an out-group more when they were led to believe that it was relatively short. Finally, Study 3 applied a reverse correlation approach, demonstrating that participants in general, and especially those scoring high on SDO, represented shorter groups in ways less consistent with full humanity than they represented taller groups. Together, this research demonstrates that basic physical height cues shape the perceived humanity of out-groups
White Look-Alikes: Mainstream Culture Adoption Makes Immigrants "Look" Phenotypically White
White Americans generally equate "being American" with "being White." In six studies, we demonstrate that White Americans perceive immigrants who adopt American mainstream culture as racially White and, reciprocally, perceive White-looking immigrants as assimilating more. In Studies 1 and 2, participants visually represented immigrants who adopted U.S. culture by acculturating to mainstream American culture or by holding a common or dual identity as more phenotypically White and less stereotypic in appearance. In Studies 3 and 4, these processes explained why participants were less likely to racially profile immigrants but also regarded them as less qualified for integration support. In Study 5, participants perceived light skin to fit to high U.S. culture adoption and dark skin to low U.S. culture adoption. Finally, in Study 6, light-skinned immigrants were seen as less threatening because they were perceived as assimilating more. Immigrants’ acculturation orientation and appearance interact and shape how they are evaluated
Acculturation preferences and perceived (dis)loyalty of Muslims in the U.K.: Two vignette-based experimental studies
Muslims in the U.K. who maintain their religious culture are often viewed as a suspect community. This pre-registered experimental research examined the mediating role of perceived (dis)loyalty as underlying process and the moderating role of acculturation expectations. A total of 334 non-Muslim White British participants in Study 1 and 810 in Study 2 were asked to indicate their acculturation expectations towards Muslims. They were then randomly assigned to read a text that described Muslims in a fictional town as either (a) maintaining their religious culture or (b) adopting the mainstream British culture, or they read (c) a neutral control text. As expected, in Study 1, when Muslims were presented as maintaining their religious culture, trust decreased compared to the control group. Conversely, when described as adopting the mainstream culture, trust increased while support for surveillance of Muslims decreased. Both effects were mediated by the perception of Muslims being disloyal or loyal to the U.K in both studies, respectively. Perceived loyalty to their religious group did not significantly mediate any effect. We replicated these findings in Study 2. Moreover, we showed that describing Muslims as maintaining their religious culture decreased trust and increased support for surveillance especially among participants who expected Muslims to give up their religious culture. Moderated mediation analysis showed that these effects were partly mediated by perceived loyalty to the U.K. We discuss the societal implications of the findings for policymakers and Muslim leaders along with recommendations for future research.publishedVersio
Calculating the Expected Value of Sample Information in Practice: Considerations from Three Case Studies
Investing efficiently in future research to improve policy decisions is an
important goal. Expected Value of Sample Information (EVSI) can be used to
select the specific design and sample size of a proposed study by assessing the
benefit of a range of different studies. Estimating EVSI with the standard
nested Monte Carlo algorithm has a notoriously high computational burden,
especially when using a complex decision model or when optimizing over study
sample sizes and designs. Therefore, a number of more efficient EVSI
approximation methods have been developed. However, these approximation methods
have not been compared and therefore their relative advantages and
disadvantages are not clear. A consortium of EVSI researchers, including the
developers of several approximation methods, compared four EVSI methods using
three previously published health economic models. The examples were chosen to
represent a range of real-world contexts, including situations with multiple
study outcomes, missing data, and data from an observational rather than a
randomized study. The computational speed and accuracy of each method were
compared, and the relative advantages and implementation challenges of the
methods were highlighted. In each example, the approximation methods took
minutes or hours to achieve reasonably accurate EVSI estimates, whereas the
traditional Monte Carlo method took weeks. Specific methods are particularly
suited to problems where we wish to compare multiple proposed sample sizes,
when the proposed sample size is large, or when the health economic model is
computationally expensive. All the evaluated methods gave estimates similar to
those given by traditional Monte Carlo, suggesting that EVSI can now be
efficiently computed with confidence in realistic examples.Comment: 11 pages, 3 figure
Facial emotion detection in Vestibular Schwannoma patients with and without facial paresis
This study investigates whether there exist differences in facial emotion detection accuracy in patients suffering from Vestibular Schwannoma (VS) due to their facial paresis. Forty-four VS patients, half of them with, and half of them without a facial paresis, had to classify pictures of facial expressions as being emotional or non-emotional. The visual information of images was systematically manipulated by adding different levels of visual noise. The study had a mixed design with emotional expression (happy vs. angry) and visual noise level (10% to 80%) as repeated measures and facial paresis (present vs. absent) and degree of facial dysfunction as between subjects' factors. Emotion detection accuracy declined when visual information declined, an effect that was stronger for anger than for happy expressions. Overall, emotion detection accuracy for happy and angry faces did not differ between VS patients with or without a facial paresis, although exploratory analyses suggest that the ability to recognize emotions in angry facial expressions was slightly more impaired in patients with facial paresis. The findings are discussed in the context of the effects of facial paresis on emotion detection, and the role of facial mimicry, in particular, as an important mechanism for facial emotion processing and understanding.info:eu-repo/semantics/publishedVersio

Lateralization of facial emotion processing and facial paresis in Vestibular Schwannoma patients
This study investigates whether there exist differences in lateralization of facial emotion processing in patients suffering from Vestibular Schwannoma (VS) based on the presence of a facial paresis and their degree of facial functioning as measured by the House Brackmann Grading scale (HBG).info:eu-repo/semantics/publishedVersio
Quality of life, social function, emotion, and facial paresis in Dutch vestibular schwannoma patients
The present study aimed to replicate the finding that vestibular schwannoma (VS) patients with facial paresis experience lower health related quality of life (QoL) than those without facial paresis in a Dutch sample, and to extend these findings by measuring VS patients' overall satisfaction with life, social function, and emotion.info:eu-repo/semantics/publishedVersio
Psychological interventions countering misinformation in social media : a scoping review : research protocol
Introduction: Misinformation is a complex concept and its meaning can encompass several kinds of different phenomena. Liang Wu et el. consider a wide variety of online behavior as misinformation:1 unintentionally spreading false information, intentionally spreading false information, disseminating urban legends, sharing fake news, unverified information, and rumors, as well as crowdturfing, spamming, trolling, and propagating hate speech, or being involved in cyberbullying. The aim of this review is to address the following question: “What psychological interventions countering misinformation can be deployed on popular social media platforms (e.g. Twitter, Facebook)?". In order to address this question, we have designed a systematic scoping review procedure in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. 2,3 Effective measures of countering misinformation on social media are instrumental for facilitating and fostering reliable public conversation about political and social problems. Moreover, countering misinformation on social media platforms can be also considered a public health intervention, especially in the time of health emergencies, such as the COVID-19 pandemic. Methods and analysis: A scoping review is a modern, rigorous approach to synthesis science, developed among others by the Joanna Briggs Institute team. For data extractions, we plan to use the following databases: Embase, Scopus, and PubMed. For paper selection, eligibility criteria were defined
