Body-image disturbances and bulimia nervosa: An empirical analysis of recent revisions of the DSM-III

In the recent revision of the DSM-III, the diagnosis of bulimia nervosa includes the criterion of persistent overconcern with body shape and weight, which may be conceptualized as a form of body-image disturbance. The new diagnostic criteria for bulimia nervosa include only those who exhibit a binge-purge eating patern, excluding binge-eaters who, in the older DSM-III, receive a diagnosis of bulimia. This study was conducted to investigate body-image disturbances in bulimia nervosa and simple bulimia (i.e., binge-eating without purging). The experimental design included two control groups, obese and normal subjects, in order to determine whether the binge-eater had body-image disturbances different form those of normal and overweight samples. The study evaluated 596 subjects (417 normals, 109 bulimia nervosa subjects, 50 binge-eaters, and 30 obese subjects) in terms of perception of current body size and selection of ideal body size. Results indicated that the bulimia nervosa group selected a current body size larger than that selected by normals and an ideal body size smaller than that chosen by normals. However, bingeeaters did not differ from the obese control group on either current or ideal body size. These results are discussed in terms of the recent debate regarding the diagnosis of bulimia nervosa and sociocultural influences upon body-image disturbances.     

THE STORY OF THE MIND: PSYCHOLOGICAL AND BIOLOGICAL EXPLANATIONS OF HUMAN BEHAVIOR

Abstract. Persons have a curious dual nature. On the one hand, they are subjects, whose actions must be explained in terms of beliefs, desires, plans, and goals. At the same time, however, they also are physical objects, whose actions must be explicable in terms of physical laws. So far no satisfying account of this duality has been offered. Both Cartesian dualism and the modern materialist alternatives (reductionist and antireductionist) have failed to capture the full range of our experience of persons. I argue that an exciting new approach to this difficulty can be found by considering developments in clinical psychology. The clinical debate between those endorsing biological models of mental illness and those endorsing psychodynamic models mirrors broader debates in the philosophy of mind. The possible resolution of this debate through the development of integrated psychobiological models suggests a promising way to reconcile the dual nature of persons in a far more appealing way than any yet proposed.     

Selective information processing and schematic content related to eating behavior

An adaptation of the Stroop color-naming task was used to investigate selective information processing related to eating behavior in 90 undergraduate women. This study differed from previous studies by (a) treating eating behavior as a continuous variable and (b) looking at five separate categories of words including color, neutral, food, body shape, and other emotionally salient words. We did not find a strong pattern of relation between the Stroop task and eating and body image measures. Results suggest that in a nonclinical population, direct methods of accessing cognitions related to eating may be more fruitful than indirect measures.     

Current and vestigial effects of overweight among women: Fear of fat,attitudinal body image,and eating behaviors

College females completed multiple, standardized measures of their fear of fat, attitudinal body image, and binge eating and dieting. Situational weigh-in measures were taken, including latency to get on the scale and anxiety while being weighed. Based on current weight and a structured weight history questionnaire, three groups were constructed: normal-weight subjects without an overweight history (NW; n=24), normal-weight subjects who were formerly overweight (FOW; n=16), and those currently overweight (OW; n=24). Group comparisons revealed, as expected, that OW females, relative to their NW peers, had more weight-related anxieties, more negative body experiences, and more frequent past-year dieting. Consistent with Stunkard's original proposition, the FOW group regarded their bodies as fatter and less affectively satisfying and expressed more weigh-in anxiety than NW participants. Currently normal-weight FOW subjects seldom differed from the currently OW individuals. Clinical and research implications are considered, particularly with regard to the psychological sequelae of weight loss.     

Body image mediates an association between personality and mental health

Personality and body image have been identified as important correlates of mental and physical health. This study sought to explore whether body image mediates the association between the major dimensions of trait personality and self‐reported mental and physical health. In total, 451 Australian adults (121 men, 331 women; M_age = 21.88 ± 7.65 years) completed questionnaires at a single time‐point. After controlling for some demographic and anthropometric factors (e.g., body mass index), neuroticism was associated with all components of body image and mental and physical health. Extraversion, openness, and conscientiousness were associated with mental health and some components of body image. Multiple mediator models identified body image discrepancy and appearance evaluation as mediating the association between personality (neuroticism, extraversion, and conscientiousness) and mental health. No significant mediation effects were observed for physical health, and mediation effects were not moderated by participant gender. These findings provide evidence that personality relates to self‐reported mental health, in part, through the variance shared with body image.     

Lean and mean rats: Some effects of acute changes in the food supply upon territorial aggression

In experiment 1, individually housed rats subjected to short-term food restriction displayed more territorial aggression toward conspecific intruders than controls maintained on a free-feeding diet. In experiment 2, small groups of three adult male rats had access to either a standard laboratory diet or the standard diet plus sucrose. Groups with the sucrose supplement were significantly less aggressive toward intruders than controls. Sucrose availability did not produce appreciable gains in body weight but it did reliably decrease within-colony weight variation. The results suggest the existence of an effective dietary mechanism that enables a social species such as Rattus norvegicus to tolerate each other in dense feeding aggregations when food is abundant. Conversely, when food is limited, social intolerance increases and serves to limit the development of large feeding groups.     

身体活动与心理活动动词加工的ERP比较

在19名右利手被试完成词汇判断任务的同时,通过119个头皮电极记录其事件相关电位（ERP）,以此来探讨表示身体活动的动词与表示心理活动的动词之间的加工差异。研究结果表明,在200~300ms时窗,在左半球枕区附近,身体活动动词所诱发的ERP比心理活动动词所诱发的ERP在正走向上更小。在300~400ms（即类似的N400）时窗,动词类型效应出现在中线和左半球的更大的区域上,特别是中央区附近,身体活动动词所诱发的ERP比心理活动动词所诱发的ERP在负走向上更大。语言表征的神经生物学理论可以解释本研究的部分结果。     

友谊质量与青少年直觉进食：链式中介模型及性别差异

基于积极心理学,采用友谊质量量表、自我怜悯量表、身体欣赏量表和直觉进食量表,对2438名初中生进行调查,并运用结构方程模型探讨友谊质量与青少年直觉进食的关系、作用机制及其性别差异。结果表明:(1)友谊质量与直觉进食呈显著正相关;(2)自我怜悯和积极身体意象在友谊质量与直觉进食间起中介作用,且该中介作用包含三条路径:自我怜悯的单独中介作用、积极身体意象的单独中介作用以及自我怜悯-积极身体意象的链式中介作用;(3)中介效应性别差异仅出现在友谊质量与直觉进食(分维度)的关系中,即"无条件地允许进食"和"进食不受情绪影响"两个维度。研究结果为促进青少年形成积极身体意象、健康饮食行为提供了参考建议和干预指导。     

Cultural differences in body dissatisfaction: Japanese adolescents compared with adolescents from China,Malaysia, Australia,Tonga, and Fiji

Cultural influences on the body image of 133 female and 99 male Japanese adolescents aged 12–18 years (M = 15.9, SD = 1.2) were compared to those of a databank of 1233 female and 1149 male adolescents also aged 12–18 years (M = 14.9, SD = 1.5) from five cultures – Chinese, Malaysian, Australian, Tongan, and indigenous Fijian – surveyed previously using identical body image measures (Fuller‐Tyszkiewicz et al., 2012). Japanese adolescents reported the highest levels of body dissatisfaction despite possessing among the lowest body mass index (BMI) and also reported among the highest levels of media influence on their body image. Subsequent path analyses revealed that for Japanese adolescents cultural identification with modern Japanese values were associated with increased body dissatisfaction, and that this association was mediated by level of media influence. These results highlight the importance of cultural influences, as well as individual differences in cultural values, in shaping Japanese adolescents' body image.     

A Polyvocal Body

This essay aims to elucidate how multiple voices and traditions should interact with one another in the practice of ethics. First, it explores some of the major ways in which questions of bodily autonomy function in secular feminist and Jewish bioethical discourses. It then uses case studies to illuminate ways each discourse's concepts of bodily autonomy can be deeply problematic, and argues that the strengths in each discourse can serve as important correctives for the weaknesses in the other. It suggests that some formal features of rabbinic texts can serve as a model for a discourse of constant and animated mutual correction. Finally, it examines two case studies in light of this model.
