Implications of accuracy, sensitivity, and variability of body size estimations to disordered eating

The current study was conducted to investigate the relationships between body size estimations and disordered eating symptomatology. The method of constant stimuli was used to derive three measures of self-perceived body size in 93 women: (1) accuracy of body size estimations (body image distortion); (2) sensitivity in discriminating body size within blocks of trials (body image sensitivity); and (3) variability in making body size estimations between blocks of trials (body image variability). Participants also completed measures of disordered eating. Although body image distortion correlated with dietary restraint and eating concern, body image variability accounted for additional variance in these variables, as well as variance in binge eating. The relationships involving body image variability were found to be mediated by body dissatisfaction and internalization of the thin ideal. Together, these results are consistent with the proposition that body image variability is a significant factor in disordered eating.

Assessing Reflective Parenting in Interaction With School-Aged Children

The aim of this study was to examine whether it was possible to develop a reliable and valid assessment of reflective parenting implicit in interaction with school-aged children using an adaptation of the Squiggle paradigm developed by Winnicott (1968 Winnicott, D. W. (1968). Playing: Its theoretical status in the clinical situation. International Journal of Psycho-Analysis, 49, 591–599.[PubMed], [Web of Science ®] , [Google Scholar]) and a manualized coding system (Normandin, Leroux, Ensink, Terradas, &; Fonagy, 2015 Normandin, L., Leroux, A., Ensink, K., Terradas, M. M., &; Fonagy, P. (2015). Reflective Parenting Assessment coding manual (Unpublished manual). University Laval, Québec City, QC, Canada. [Google Scholar]). A total of 158 mother–child dyads participated when children were age 5 to 12. Of this group, 89 children had experienced sexual abuse. Interrater reliability using the manualized coding system was excellent. The factor analysis identified a reflective parenting stance factor, in addition to an affectionate support factor and a negative parenting factor. Furthermore, there was a medium strength relationship between the mother's reflective parenting stance evident in her interactions with her child and parental reflective functioning assessed using the Parent Development Interview (Slade, Aber, Bresgi, Berger, &; Kaplan, 2004 Slade, A., Aber, J. L., Bresgi, I., Berger, B., &; Kaplan, M. (2004). The Parent Development Interview–Revised (Unpublished protocol). The City University of New York, New York, NY. [Google Scholar]), suggesting the parental reflective stance is a good indicator of parental reflective functioning in interaction. With regard to parent reports of child internalizing and externalizing behaviors, the reflective parenting stance was the only predictor of internalizing difficulties and a significant predictor of externalizing difficulties in addition to sexual abuse.     

选择性注意机制在情景线索效应中的作用

情景线索效应是指个体在视觉搜索过程中通过学习重复不变的情景信息提高搜索效率的现象。本文从情景线索效应相关行为特征、眼动特征及大脑神经活动等三个方面探讨了情景线索效应与选择性注意机制的交互作用,发现现有研究中存在着许多互相冲突的现象,增加了理解注意机制的难度。未来研究应结合认知神经科学技术寻找更多的实证数据,探索注意机制对情景线索效应的影响,以进一步完善情景线索效应中的注意机制理论。     

Emotions: from brain to robot

Some robots have been given emotional expressions in an attempt to improve human-computer interaction. In this article we analyze what it would mean for a robot to have emotion, distinguishing emotional expression for communication from emotion as a mechanism for the organization of behavior. Research on the neurobiology of emotion yields a deepening understanding of interacting brain structures and neural mechanisms rooted in neuromodulation that underlie emotions in humans and other animals. However, the chemical basis of animal function differs greatly from the mechanics and computations of current machines. We therefore abstract from biology a functional characterization of emotion that does not depend on physical substrate or evolutionary history, and is broad enough to encompass the possible emotions of robots.     

Body image attitudes and concerns among indigenous Fijian and European Australian adolescent girls

Research on body image has primarily been conducted among Western women who highly value the thin ideal body size. There has been limited research that has examined body image attitudes among Fijian adolescent girls who are exposed to both traditional sociocultural pressures that promote a larger body size and Western pressures that promote slimness. Using in-depth semi-structured interviews, we examined the factors associated with body image attitudes and concerns among a sample of 16 indigenous Fijian and 16 European Australian adolescent girls aged between 13–18 years. An inductive analysis of girls’ responses indicated that both groups of girls experienced body image concerns including body dissatisfaction, a preference for thinness and concerns associated with weight gain. These findings have implications for our understanding of the role of culture in shaping body image among girls and may prove useful in the development of future survey research that can be implemented among both Fijian and Western adolescents.     

Sociocultural Influences on Body Image Concerns and Body Change Strategies Among Indigenous and Non-Indigenous Australian Adolescent Girls and Boys

Sociocultural messages about the ideal body build have been studied predominantlyamong White adolescent girls. In the current study we examined the relationships between perceived sociocultural influences, body image concerns, and body change strategies among 47 (22 boys and 25 girls) Indigenous Australian adolescents. These relationships were compared to those from 47 non-Indigenous adolescents (predominantly from an Anglo-Saxon background), who were matched on gender, age, and school grade. Overall, the sociocultural influences were found to be associated with body image concerns and body change strategies among both cultural groups. The only exception was that the sociocultural influences were not associated with the Indigenous girls’ levels of body dissatisfaction or body image importance. These findings are discussed in relation to past studies of White and Black girls.     

Body Image and Self-Esteem Across Age and Gender: A Short-Term Longitudinal Study

This study examined the relationship between body image and self-esteem across time and age for men and women. Participants were 150 men and 239 women aged between 20 and 86 years (M?=?59.73), recruited from the general population in Australia. They completed a questionnaire assessing self-esteem, body dissatisfaction, body importance, and a range of other domains of life satisfaction at baseline and 2 years later. Cross-sectionally, we found that higher self-esteem was associated with lower body dissatisfaction, but there was no consistent relationship between these variables across time for age and gender. Women were more dissatisfied with their bodies than men; yet, men placed greater importance on their appearance than women, and also reported high levels of body dissatisfaction.     

Interest and Beliefs About BRCA Genetic Counseling Among At-Risk Latinas in New York City

Background: Latinas are less likely to use genetic services (counseling and testing) for hereditary breast and/or ovarian cancer risk compared to other ethnic groups. Meanwhile, little is known about barriers to genetic counseling among Latinas at increased risk of inherited breast cancer. Methods: A two-phase pilot study was conducted to examine interest, barriers and beliefs about BRCA genetic counseling among at-risk Latinas in New York City and explore the potential for developing a culturally-tailored narrative educational tool for use in future studies. Phase 1 included quantitative telephone interviews (N = 15) with bilingual participants with a personal diagnosis at a young age and/or family history of breast and/or ovarian cancer. Quantitative results informed development of a narrative prototype educational presentation viewed by a subset of participants (N = 10) in Phase 2 focus groups. Results: Despite barriers, including lack of awareness/knowledge, concerns related to learning cancer risks of family members, and concerns about cost/health insurance, participants reported positive attitudes, beliefs and interest in learning about BRCA genetic counseling. Further, significant increases in knowledge were demonstrated from pre-post presentation (p = 0.04). Conclusion: There is an unmet need to educate at-risk Latinas about BRCA genetic counseling. Culturally-tailored educational materials including narratives may increase knowledge about BRCA genetic counseling among this underserved group. The effectiveness of these approaches should be tested in future research with larger samples.
