Sex–related self–concepts, cognitive styles and cultural values of traditionality–modernity as predictors of general and domain–specific sexism

Previous studies have determined that masculinity, femininity, need for closure and authoritarianism are significant predictors of sexism. The present study attempted to integrate these variables in order to better understand the nature of general ambivalent sexism and workplace–specific sexism in Singapore. Chinese traditionality and Chinese modernity were specifically examined as potential predictors of sexism. Robust results from hierarchical regressions indicated that these indigenous cultural variables were highly important in predicting general and workplace–specific sexism. Although masculinity and need for closure were unrelated to sexism, participant sex, femininity and authoritarianism significantly predicted sexist attitudes towards women. Most important, Chinese values were found to add significant incremental validity in predicting sexist attitudes beyond what was accounted by the aforementioned predictors. Chinese traditionality significantly predicted sexist attitudes towards women, but Chinese modernity was unrelated to sexism. Implications of these findings were discussed.     

Current scientific interest in dissociative amnesia: A bibliometric analysis

In a bibliometric analysis, we used the PubMed search engine to count the number of publications identified by the search term “dissociative amnesia” for the years 2011–2020. We then counted publications from the same decade for five representative comparison disorders: “panic disorder,” “anorexia nervosa,” “obsessive–compulsive disorder,” “attention deficit hyperactivity disorder,” and “bipolar disorder.” Our search yielded only 89 publications for “dissociative amnesia,” and only seven of these involved localized or selective amnesia for specific events. By contrast, we found between 3000 and 21,000 publications for each of the five comparison disorders during 2011–2020. We performed several additional secondary analyses, all of which suggested that the diagnosis of “localized or selective dissociative amnesia” has generated little scientific interest in recent years. Examining possible hypotheses to explain this lack of interest, it appears most likely that the concept of localized or selective dissociative amnesia is not widely accepted among scientists at present.     

Childhood contact predicts hemispheric asymmetry in cross-race face processing

Participants typically process same-race faces more quickly and more accurately than cross-race faces. This deficit is amplified in the right hemisphere of the brain, presumably due to its involvement in configural processing. The present research tested the idea that cross-race contact tunes cognitive and perceptual systems, influencing this asymmetric race-based deficit in face processing. Participants with high and low levels of contact performed a lateralized recognition task with same- and cross-race faces. Replicating prior work, participants with minimal contact showed cross-race deficits in processing that were larger in the right hemisphere. For participants with more contact, this lateralized deficit disappeared. This effect of contact seems to be independent of race-based attitudes (e.g., prejudice).     

More or less: spontaneous quantity discrimination in the domestic cat

We examined spontaneous quantity discrimination in untrained domestic cats in three food choice experiments. In Experiment 1, we presented the cats with two different quantities of food in eight numerical combinations. Overall, the subjects chose the larger quantity more often than the smaller one, and significantly so when the ratio between the quantities was less than 0.5. In Experiment 2, we presented the cats with two pieces of food in four different size combinations. Again, subjects chose the larger piece above chance, although not in the combination where the largest item was presented. In Experiment 3, a subset of the cats was presented multiple times with two different quantities of food, which were hidden from view. In this case, the cats did not choose the larger quantity more often than the smaller one, suggesting that in the present experiments they mainly used visual cues when comparing quantities. We conclude that domestic cats are capable of spontaneously discriminating quantities when faced with different numbers or sizes of food items, and we suggest why they may not always be motivated to choose the larger quantity. In doing so, we highlight the advantages of testing spontaneous choice behavior, which is more likely to reflect animals’ everyday manner of responding than is the case when training them in order to test their absolute limits of performance which may not always coincide with their daily needs.     

Thin Is In? Think Again: The Rising Importance of Muscularity in the Thin Ideal Female Body

Research has documented an increased emphasis on fitness in media targeting women. However, it is unclear whether this emphasis has resulted in increased muscularity in the perceived ideal female body shape. We sought to evaluate whether the ideal female figure has incorporated increased muscularity into the existing ideal body type that already emphasizes thinness. In Study 1, 78 female undergraduates evaluated images of U.S. beauty pageant winners over the past 15 years on dimensions of thinness, muscularity, and attractiveness. Results indicated that muscularity and thinness ratings of pageant winners significantly increased over time. In Study 2, 64 female undergraduates evaluated two different versions of the same image of a model: a Thin Muscular image and a Thin Only image in which the appearance of muscularity was removed through digital editing. When images were presented in pairs, results indicated that participants found the Thin Muscular image more attractive than the Thin Only image. These results suggest that the current perceived ideal female figure includes both extreme thinness and muscularity and that women prefer this muscular thin figure to a solely thin figure. These findings have implications for clinical treatments related to body image, compulsive exercise, and media literacy.
