Cueing the interpretation of a Necker Cube: a way to inspect fundamental cognitive processes

The term perceptual bistability refers to all those conditions in which an observer looks at an ambiguous stimulus that can have two or more distinct but equally reliable interpretations. In this work, we investigate perception of Necker Cube in which bistability consists of the possibility to interpret the cube depth in two different ways. We manipulated the cube ambiguity by darkening one of the cube faces (cue) to provide a clear cube interpretation due to the occlusion depth index. When the position of the cue is stationary the cube perceived perspective is steady and driven by the cue position. However, when we alternated in time the cue position (i.e. we changed the position of the darkened cube face) two different perceptual phenomena occurred: for low frequencies the cube perspective alternated in line with the position of the cue; however for high frequencies the cue was no longer able to bias the perception but it appears as a floating feature traveling across the solid with the cube whole perspective that returns to be bistable as in the conventional, bias-free, case.

Perceived acceptability of anorexia and bulimia in women with and without eating disorder symptoms

Perceptions of the acceptability of eating‐disordered behaviour were examined in young adult women with (n = 44) and without (n = 268) eating disorder symptoms. All participants viewed vignettes of anorexia nervosa (AN) and bulimia nervosa (BN) and responded to the same series of questions—addressing different possible ways in which the conditions described might be seen to be acceptable—in relation to each vignette. Participants with eating disorder symptoms perceived eating‐disordered behaviour to be more acceptable than asymptomatic participants, and this was the case for both AN and BN vignettes and for a range of different items. Differences on items tapping the perception that it ‘might not be too bad’ to have an eating disorder and that an eating disorder is ‘nothing to be concerned about’ were particularly pronounced. The findings could not be accounted for by between‐group differences in body weight. The findings indicate the ambivalence towards eating‐disordered behaviour that exists among a subgroup of young women in the community and the clear association between such ambivalence and actual eating disorder symptoms. The perceived acceptability of eating‐disordered behaviour may need to be addressed in prevention and early‐intervention programs for eating disorders.
