Neural predictors of evaluative attitudes toward celebrities.

ABSTRACT: Our attitudes toward others influence a wide range of everyday behaviors and have been the most extensively studied concept in the history of social psychology. Yet they remain difficult to measure reliably and objectively, since both explicit and implicit measures are typically confounded by other psychological processes. We here address the feasibility of decoding incidental attitudes based on brain activations. Participants were presented with pictures of members of a Japanese idol group inside an functional magnetic resonance imaging scanner while performing an unrelated detection task, and subsequently (outside the scanner) performed an incentive-compatible choice task that revealed their attitude toward each celebrity. We used a real-world election scheme that exists for this idol group, which confirmed both strongly negative and strongly positive attitudes toward specific individuals. Whole-brain multivariate analyses (searchlight-based support vector regression) showed that activation patterns in the anterior striatum predicted each participant's revealed attitudes (choice behavior) using leave-one-out (as well as 4-fold) cross-validation across participants. In contrast, attitude extremity (unsigned magnitude) could be decoded from a distinct region in the posterior striatum. The findings demonstrate dissociable striatal representations of valenced attitude and attitude extremity and constitute a first step toward an objective and process-pure neural measure of attitudes.

Project description:The large inflow of asylum-seekers in recent years has heralded a diversification in adopted asylum policies across European societies. Although a growing body of research has addressed these versatile approaches and their implications for the European integration project, insight into the social basis of these restrictive or open asylum policies remains underdeveloped. Hence, the current study provides detailed insight into public preferences for asylum policies and offers a new understanding of how these attitudes are affected by diverging socio-economic realities across Europe. In addition, this paper considers the role of individual factors that coincide with publicly adopted frames in contemporary asylum debates. In particular, to explain how contextual differences reflect on opinion climates, the impacts of the policy, economic, and migratory context are studied. On the individual-level, we focus on threat perception and human values, which represent humanitarian, economic, and cultural frames. To explore these relations, data on 20 countries from the European Social Survey Round 8 (2016) are analyzed through a multilevel structural equation modeling approach. Results indicate that, on the contextual-level, only unemployment rates have a significant impact and, rather surprisingly, lower unemployment rates provoke a more negative opinion climate. Yet, this relationship seems to be largely driven by some specific countries that are characterized by large unemployment rates and relatively positive opinion climates simultaneously. The migratory and policy context, on the other hand, do not influence attitudes toward asylum policy. This indicates that it is not necessarily the countries facing the largest inflow of asylum-seekers or issuing the most positive decisions on asylum applications that have the most restrictive opinion climates. As shown by the important roles of human values and threat perceptions, which represent widely adopted frames, public discourses seem much more important in explaining attitudes toward asylum policy across Europe.

Project description:BACKGROUND:Bone densitometry (e.g., dual-energy X-ray absorptiometry or "DXA") is strongly associated with osteoporosis treatment; however, rates of DXA are low. While studies have demonstrated a continued need for primary care provider education on the role of DXA in preventive care, little is known about the role of patient attitudes toward DXA. This review's purpose is to synthesize the evidence about the effects of patient perceptions and experiences of DXA on osteoporosis prevention. METHODS:A metasynthesis was conducted of English language, peer-reviewed publications, searching relevant databases: MEDLINE, CINAHL, Web of Science Social Science Citation Index, PsycINFO, and Sociological Abstracts. Identified articles' quality was appraised using the Critical Appraisal Skills Programme (CASP) Qualitative Checklist, and an iterative process of data evaluation, integration, and synthesis was used to develop the findings. RESULTS:Thirteen articles from ten studies were identified, composing an aggregated sample of 265 people (231 women). Participant attitudes toward screening ranged from receptive to ambivalent to concerned about results. Participants' understandings of DXA and its role in clinical care were limited. Knowledge of osteoporosis was also partial and influenced by lay sources, the media, and health care providers. Primary care providers strongly influenced participant behavior, especially if participants had a more passive approach to health care. Participants reported less concern about expected barriers of health care access and cost. CONCLUSION:Minimal knowledge exists of patient perceptions and experiences of DXA among those who are fracture naïve: Prior research has focused primarily on secondary fracture prevention contexts. Our metasynthesis reveals patients' significant reliance, given their limited risk appraisal and knowledge, upon primary care providers in decision-making. We urge colleagues to conduct qualitative research on DXA barriers among general primary care population in order to facilitate health care delivery systems better equipped to diagnose and treat patients before their first fracture.
