Effect of Childhood Traumas on Eating Disorders: Systematic Review

This systematic review is aimed at evaluating the relationship between eating disorders (ED) such as anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), a controversial and new concept in recent years; orthorexia nervosa (ON) and childhood traumas (CT). The purpose of this review is to systematically examine whether CT (emotional-physical-sexual abuse and emotional-physical neglect) has any impact on the development of the ED (anorexia-bulimia nervosa, binge eating disorder, orthorexia nervosa) in line with the literature. In this review, Turkish and English articles/dissertations published between 1990 and 2022 in the academic databases of Ebscohost, Proquest Dissertations, Science Direct, Google Scholar and PsycINFO were used to examine the effect of CT on the development of ED. Childhood traumas, eating disorders, aneroxia nervosa, bulimia nervosa, binge eating disorder, orthorexia nervosa, childhood traumas and childhood traumas and eating disorders, childhood traumas and orthorexia nervosa were used as keywords. From the articles/dissertations reached, those who did not have an efficacy study of childhood traumas on eating disorders/orthorexia nervosa and those published before 1990 and after 2022 were not included in the review. Each selected study focused on information on the effects of childhood trauma types on eating disorders and orthorexia nervosa. In line with the determined criteria, the methods, findings and results of the studies of 21 articles/dissertations were explained. It was determined that the types of CT (emotional, physical, sexual abuse and physical and emotional neglect) directly or indirectly predicted ED and were effective on the development of ED, but no effect on ON was observed. This conclusion sheds light on the need to increase studies on ON

Extrapolating continuous color emotions through deep learning

By means of an experimental dataset, we use deep learning to implement an RGB (red, green, and blue) extrapolation of emotions associated to color, and do a mathematical study of the results obtained through this neural network. In particular, we see that males (type-m individuals) typically associate a given emotion with darker colors, while females (type-f individuals) associate it with brighter colors. A similar trend was observed with older people and associations to lighter colors. Moreover, through our classification matrix, we identify which colors have weak associations to emotions and which colors are typically confused with other colors

The sun is no fun without rain : Physical environments affect how we feel about yellow across 55 countries

Across cultures, people associate colours with emotions. Here, we test the hypothesis that one driver of this cross-modal correspondence is the physical environment we live in. We focus on a prime example – the association of yellow with joy, – which conceivably arises because yellow is reminiscent of life-sustaining sunshine and pleasant weather. If so, this association should be especially strong in countries where sunny weather is a rare occurrence. We analysed yellow-joy associations of 6625 participants from 55 countries to investigate how yellow-joy associations varied geographically, climatologically, and seasonally. We assessed the distance to the equator, sunshine, precipitation, and daytime hours. Consistent with our hypotheses, participants who live further away from the equator and in rainier countries are more likely to associate yellow with joy. We did not find associations with seasonal variations. Our findings support a role for the physical environment in shaping the affective meaning of colour.Peer reviewe

Social support and help-seeking worldwide

Social support has long been associated with positive physical, behavioral, and mental health outcomes. However, contextual factors such as subjective social status and an individual’s cultural values, heavily influence social support behaviors (e.g., perceive available social support, accept support, seek support, provide support). We sought to determine the current state of social support behaviors and the association between these behaviors, cultural values, and subjective social support across regions of the world. Data from 6,366 participants were collected by collaborators from over 50 worldwide sites (67.4% or n = 4292, assigned female at birth; average age of 30.76). Our results show that individuals cultural values and subjective social status varied across world regions and were differentially associated with social support behaviors. For example, individuals with higher subjective social status were more likely to indicate more perceived and received social support and help-seeking behaviors; they also indicated more provision of social support to others than individuals with lower subjective social status. Further, horizontal, and vertical collectivism were related to higher help-seeking behavior, perceived support, received support, and provision of support, whereas horizontal individualism was associated with less perceived support and less help-seeking and vertical individualism was associated with less perceived and received support, but more help-seeking behavior. However, these effects were not consistently moderated by region. These findings highlight and advance the understanding of how cross-cultural complexities and contextual distinctions influence an individual's perception, processing, and practice of social support embedded in the changing social landscape.</p
