Dynamic Simulation and Static Matching for Action Prediction: Evidence From Body Part Priming

Accurately predicting other people's actions may involve two processes: internal real‐time simulation (dynamic updating) and matching recently perceived action images (static matching). Using a priming of body parts, this study aimed to differentiate the two processes. Specifically, participants played a motion‐controlled video game with either their arms or legs. They then observed arm movements of a point‐light actor, which were briefly occluded from view, followed by a static test pose. Participants judged whether this test pose depicted a coherent continuation of the previously seen action (i.e., “action prediction task”). Evidence of dynamic updating was obtained after compatible effector priming (i.e., arms), whereas incompatible effector priming (i.e., legs) indicated static matching. Together, the results support action prediction as engaging two distinct processes, dynamic simulation and static matching, and indicate that their relative contributions depend on contextual factors like compatibility of body parts involved in performed and observed action.     

Reduce temptation or resist it? Experienced temptation mediates the relationship between implicit evaluations of unhealthy snack foods and subsequent intake

A more negative implicit evaluation of unhealthy food stimuli and a more positive implicit evaluation of a weight-management goal have been shown to predict lower consumption of unhealthy food. However, the associations between these evaluations, temptation to indulge and consumption of unhealthy food remain unclear. The current study investigated whether temptation would mediate the relationship between implicit food and goal evaluations and consumption (resembling an antecedent-focused route to self-control of eating), or whether those evaluations would moderate the relationship between temptation and consumption (resembling a response-focused route). A sample of 156 women (17–25 years), who tried to manage their weight through healthy eating, completed two implicit association tasks assessing implicit food and goal evaluations, respectively. Intake of four energy-dense snack foods was measured in a task disguised as a taste test, and participants reported the strength of experienced temptation to indulge in the snacks offered. Negative implicit food evaluation was associated with lower snack intake, and temptation mediated this relationship. Implicit goal evaluation was unrelated to both temptation strength and snack consumption. The findings contribute to an understanding of how negative implicit unhealthy food evaluation relates to lower consumption, namely through the mediation of temptation to indulge in those foods.     

Barth and Darwin: What is Humanity?

Abstract

Karl Barth proposed that secular texts including scientific theories could be understood as parables of aspects of the revealed truth not as such available to natural science. I explore that suggestion, seeking to understand what human biology in succession to the work of Charles Darwin has to contribute alongside Barth's doctrine of the human person.     

Long‐term Self‐monitoring of Weight: A Case Study

The aim of this study was to examine the self‐monitoring of weight on a daily basis over a long period of time in order to understand the process of weight regain. An obese female client measured her weight every morning over a period of 10 years. The subject made a total of 2081 weight measurements. Thus, her weight was measured on 67% of all possible days. After the initial weight loss a pattern of gradual weight gain was observed. The subject gained weight during August and September, and at the end of December, in particular. Furthermore, her weight increased slightly at the weekends. This case study highlights the advantage of self‐monitoring of weight on a daily basis. Individual patterns of weight change possibly associated with season and weekly variation may be crucial when obese subjects try to maintain their weight after weight loss. However, it may take several months or even years to detect the weekly and yearly rhythms or other patterns in the data. Thus, self‐control of weight is problematic, since patterns in the weight regain process are difficult to detect. This may be one reason why self‐control of weight is so difficult.     

A response to Dr Anthony Daniels

One of the sources of the diversity within psychotherapy is the conceptualization of the body. There are three main ways in which the body is seen. These correspond to three levels within the Wilber (1996) structural model. At level 1 the body is seen as something quite separate from the mind. We can treat the mind independently and leave the body to other specialists, such as medical doctors. If we do deal with the body, it is only in an external and behavioural way. At level 2 the body is seen as integrated with the mind, and the client is encouraged to see it this way too. One of the aims is bodymind unity. The body is continually referred to, and may be touched or asked to go through certain motions as part of the therapy. At level 3 the body is seen as the site for symbolic representations of divine archetypes, and reference is made to the subtle body. Both mind and body are seen as part of something greater, the soul. All three of these approaches are to be found within psychotherapy. It is argued that, unless these divisions are taken seriously, psychotherapy will remain confused. It is already confusing to others. By removing this particular form of confusion, it will be easier for psychotherapists to know what they are doing, and the scope and limits of their own particular orientation. Of these three versions of the body, the third is probably the least well known, but is growing the fastest. More lengthy attention is therefore paid to that.     

Body size and body esteem in women: The mediating role of possible self expectancy

We predicted that an expectancy of acquiring a feared fat self and an expectancy of acquiring a hoped-for thin self both mediate the impact of body size on women's body esteem. We also predicted that the mediating pathway through the feared fat self would be stronger than that through the hoped-for thin self. A community sample of 251 women reported their age, height, weight, and completed measures of body esteem and expectancy perceptions of acquiring the feared fat and hoped-for thin selves. Bayesian Structural Equation Modeling (SEM) demonstrated that expectancies about the feared fat self and about the hoped-for thin self mediated the relationship between body size and body esteem. Bayesian SEM also revealed that the pathway through the feared fat self was stronger than that through the hoped-for thin self. Implications for future research and the development of eating pathology are discussed.     

“Never reflected anywhere”: Body image among ethnoracialized gay and bisexual men

A growing body of literature has highlighted the increased prevalence of body image concerns and associations with health outcomes among gay and bisexual men (GBM). Little research, however, has examined the link between body image and social oppression for ethnoracialized GBM. Using an intersectionality lens and qualitative inductive analysis, data were collected through focus groups and interviews with GBM (n = 61) who identify with one of four ethnoracial groups (Black, East/Southeast Asian, South Asian, Latino/Brazilian). Three main themes emerged: (1) body image idealization in gay/bisexual male culture, (2) negotiating a racialized body image, and (3) negotiating the impact of body image on relationship with self and others. The study results highlighted how multiple forms of oppression (e.g., racism, sexism) intersected with one another to impact the body image and overall well-being among ethnoracialized GBM.     

Effects of exposure to thin-ideal media images on body dissatisfaction: Testing the inclusion of a disclaimer versus warning label

The current study was designed to determine whether the inclusion of a disclaimer (i.e., “Retouched photograph aimed at changing a person's physical appearance.”) or warning (i.e., “Warning: Trying to look as thin as this model may be dangerous to your health.”) added to images of thin/attractive models would affect body dissatisfaction and intent to diet in female undergraduate students (n = 342). Participants were randomly assigned to one of four groups: (a) disclaimer, (b) warning, (c) model control, or (d) car control. Results revealed a significant interaction between group and time, whereby only the car control group reported a significant change (i.e., decrease) in body dissatisfaction over time. Groups did not differ on intent to diet measured at post-exposure. The results largely replicate other findings in this area and call into question advocacy efforts to label media images as a strategy to decrease women's identification with the stimuli.     

Body checking and avoidance in ethnically diverse female college students

Although body checking and avoidance behaviors are common in women with eating disorders, minimal research has examined the nature or correlates of these behaviors in ethnically diverse female college students without eating disorders. Self-identified European American (n = 268), Asian American (n = 163), Latina (n = 146), and African American (n = 73) women completed self-report measures of body checking and avoidance, thin-ideal internalization, eating pathology, and clinical impairment. Results indicated that European and Asian American women reported significantly more body checking and avoidance than African American and Latina women. Generally, correlates of body checking and avoidance were consistent across ethnic groups: Regression analyses indicated that type of ethnicity predicted body checking and avoidance; and ethnicity, body checking, and body avoidance predicted eating pathology and clinical impairment. These associations suggest that body checking and avoidance are not benign behaviors in diverse nonclinical women.     

Drive for leanness and health-related behavior within a social/cultural perspective

We examined relationships between drive for leanness and perceived media pressure to change appearance, internalization of an ideal physique, exercise frequency, and dieting. Men and women (N = 353) completed the Drive for Leanness Scale, the Sociocultural Attitudes Toward Appearance Questionnaire-3, the Eating Attitudes Test-26, and a demographic inventory. Drive for leanness was significantly correlated with athletic internalization (.52), pressure to attain an ideal physique (.25), exercise frequency (.36), and dieting (.25). Structural equation modeling revealed a good fitting model (χ² = 2.85, p < .241; CFI = .99; NNFI = .98; RMSEA = .04; SRMR = .02) with internalization predicting drive for leanness, which in turn predicted dieting and exercise. Results reveal social/cultural theory helps enhance the understanding of the drive for leanness and its relationship with health-related behavior.
