Exposure to simulated nature promotes positive body image irrespective of the presentation modality: a comparison of images, 2-dimensional film, and 360o immersive film

Previous studies have shown that exposure to simulated natural environments can elevate state body appreciation, but stimulus sets have been limited to the use of images and 2-dimensional (2D) film. To extend this work, we examined the relative impact of images, 2D film, and a 360o immersive film on immediate, state body appreciation. A total of 136 German-speaking adults from Austria (71.3% women; age range 18-69 years) were randomly assigned to one of three conditions, in which they viewed an image set, a 2D film, or a 360o film depicting the same natural environment. Before and after viewing the stimuli, they completed measures of state body appreciation, affect, and desire for aesthetics. Our results showed that state body appreciation improved in all three conditions, with effect sizes ranging from Cohen’s d = 0.26 (2D film) to 0.52 (360o film). Presentation modality did not significantly shape improvements in state body appreciation; that is, the elevation in state body appreciation was equivalent across all three groups. Participants also experienced improvements in feelings of pleasantness, but again this was independent of the experimental group. These results suggest exposure to simulated nature may improve state body appreciation irrespective of the presentation modality.</p

Large-scale cross-societal examination of real- and minimal-group biases

Biases in favor of culturally prevalent social ingroups are ubiquitous, but random assignment to arbitrary experimentally created social groups is also sufficient to create ingroup biases (i.e., the minimal group effect; MGE). The extent to which ingroup bias arises from specific social contexts versus more general psychological tendencies remains unclear. This registered report focuses on three questions. First, how culturally prevalent is the MGE? Second, how do critical cultural and individual factors moderate its strength? Third, does the MGE meaningfully relate to culturally salient real-world ingroup biases? We compare the MGE to bias in favor of a family member (first cousin) and a national ingroup member. We propose to recruit a sample of &amp;gt; 200 participants in each of &amp;gt; 50 nations to examine these questions and advance our understanding of the psychological foundations and cultural prevalence of ingroup bias
