Food cravings consume limited cognitive resources

Using Tiffany's (1990) cognitive model of drug use and craving as a theoretical basis, the present experiments investigated whether cravings for food expend limited cognitive resources. Cognitive performance was assessed by simple reaction time (Experiment 1) and an established measure of working memory capacity, the operation span task (Experiment 2). In each experiment, female undergraduate students were randomly assigned to a craving or control condition. Participants in the craving condition abstained from eating chocolate for 24 hours prior to testing and performed the cognitive task in the presence of chocolate, a manipulation that successfully elicited chocolate cravings. In both experiments, there was no main effect of craving condition on cognition, but there was a significant interaction between condition and trait chocolate craving. In support of Tiffany's model, our results show that habitual food cravers direct limited cognitive resources to craving-related cues, at the cost of competing cognitive demands.

GENDER DIFFERENCES IN INTERNAL BELIEFS ABOUT WEIGHT AND NEGATIVE ATTITUDES TOWARDS SELF AND OTHERS

Previous research has found that people with an internal weight locus of control (beliefs in self-control over weight) are more likely to join and stay in weight-loss programs and have higher self-esteem than those who have an external locus of control (e.g., belief that weight is due to luck, genes). There has been no research on how weight locus of control affects the self-esteem of people who are not average weight or not satisfied with their weight. The present study predicted that for people who are overweight, weight locus of control would be negatively related to self-esteem. The results confirmed this interaction between weight locus of control and weight on self-esteem for women, but not for men. The second prediction was that internal weight locus of control would have negative social consequences in terms of greater negative stereotyping of obese people, and this was also confirmed for women. Because weight loss is rarely permanent, it would seem important to change people's attitudes about the lack of control that they (and others) have over body weight.     

Learned helplessness and IQ differences

Two groups of adult Ss differing in verbal IQ were compared in a learned helplessness experiment involving cognitive tasks and non-contingent rewards. The mean IQs for the two groups were 131 and 117. As predicted, the higher IQ Ss performed better overall and showed greater awareness of the response-outcome contingency. Their test-task performance was also more affected by the contingency manipulation although this occured only with success feedback. Implications of the results for cognitive accounts of human helplessness are discussed.     

Body image across the adult life span: stability and change

By far, the majority of studies investigating body image in adults have drawn samples from college populations within a very narrow age range. The purpose of the present paper is to review empirical research on the body image of adults older than the typical college student. There are marked changes in appearance across the adult life span, especially for women, which lead to the expectation of concomitant changes in body image. In fact, the review found that body dissatisfaction was remarkably stable across the adult life span for women, at least until they are quite elderly. In contrast, the importance of body shape, weight and appearance decreased as women aged, underscoring an important distinction between evaluation and importance of the body. However, there are many large gaps and limitations in the current literature that will need to be addressed before a more complete understanding of the development of body image across the adult life span is achieved.     

Negative Stereotyping of Obesity in Children: The Role of Controllability Beliefs

This study investigated the extent of negative stereotyping of obesity (compared to negative stereotyping of height) in children and its relationship with the perception of obesity as controllable. Questionnaires measuring negative stereotyping and controllability beliefs about weight (and height) were completed by 96 children from Grades 4 to 6. Consistent negative stereotyping of obesity was found for both child and adult targets, regardless of the child's own gender, age, or weight, Likewise, children uniformly believed obesity to be largely under volitional control. The degree of controllability assigned to obesity was positively correlated with the extent of negative stereotyping. It was concluded that control beliefs may provide a vehicle for changing the strong negative attitudes displayed toward fat people.

Conditions of visual verbal extinction: does the ipsilesional stimulus have to be identified?

Six left-neglect patients were presented with four-letter words in the left and/or right hemifield, in different contextual conditions: unilateral, bilateral-x in which one word appears on one side and a string of "x" appears on the other side (the side of "x' was not predictable), and bilateral-word (presentation of one word in each hemifield). In Experiment 1, left extinction occurred even if the right stimulus was an easily discriminable string of "x." Experiment 2 showed that increasing the size of the left stimuli reduced extinction when a string of "x" was presented on the right hemifield. However, extinction was stronger with bilateral-word presentation. These results indicate the presence of an early component in the extinction phenomenon, i.e., a "magnetic" attraction toward the ipsilesional hemifield, but are also in favor of some additional deficit, at a later stage of information processing.     

Assessing clients in their natural environments with electronic diaries: rationale, benefits, limitations, and barriers

Increasingly, mobile technologies are used to gather diary data in basic research and clinical studies. This article considers issues relevant to the integration of electronic diary (ED) methods in clinical assessment. EDs can be used to gather rich information regarding clients' day-to-day experiences, aiding diagnosis, treatment planning, treatment implementation, and treatment evaluation. The authors review the benefits of using diary methods in addition to retrospective assessments, and they review studies assessing whether EDs yield higher quality data than conventional, less expensive paper-pencil diaries. Practical considerations--including what platforms can be used to implement EDs, what features they should have, and considerations in designing diary protocols for sampling different types of clinical phenomena--are described. The authors briefly illustrate with examples some ways in which ED data could be summarized for clinical use. Finally, the authors consider barriers to clinical adoption of EDs. EDs are likely to become increasingly popular tools in routine clinical assessment as clinicians become more familiar with the logic of diary designs; as software packages evolve to meet the needs of clinicians; and as mobile technologies become ubiquitous, robust, and inexpensive.     

Impaired Fear Recognition and Social Anxiety Symptoms in Adolescence

This study represents the first examination of adolescent anxiety in relation to peer emotion recognition, rather than adult emotion recognition. Additionally, we examine potential mechanisms for the development of social anxiety in females. Facial emotion recognition (FER) is important for accurate social cognition, which is impaired in individuals with various disorders, including anxiety disorders. Social anxiety often onsets during adolescence, is observed more commonly in females, and is often associated with FER difficulties. Given the importance of peer interaction during adolescence, and some evidence that FER may differ as a function of the stimuli (adolescent or adult faces), we sought to study FER in relation to social anxiety symptoms using stimuli portraying adolescent faces. Male and female adolescents (N = 64) completed an online survey in which they rated 257 child and adolescent emotional faces and completed a self-report measure of social anxiety symptoms. We examined differences in emotion recognition (e.g., fear, anger, sadness) between individuals with high and low levels of social anxiety symptoms. Adolescents with high social anxiety symptoms were more likely to have problems correctly identifying fearful expressions (90.55 % accuracy) compared to adolescents with low social anxiety symptoms (96.00 % accuracy; t = 2.375, p = .021, d = 0.594), and this effect was observed exclusively in female adolescents. The observed sex difference in accurate identification of fearful faces in relation to social anxiety could suggest a potential mechanism for social anxiety development in adolescent females.     

Clothes Make a Difference: The Role of Self-Objectification

Objectification Theory contends that women self-objectify as a result of internalizing an observer’s perspective on their physical selves. Self-objectification has been examined as both a stable enduring trait and as a context dependent state. The present study aimed to assess the link between clothing, a neglected area of women’s appearance management, and self-objectification. Participants were 102 South Australian female undergraduate students who completed a questionnaire containing a trait measure of self-objectification, as well as four different scenarios varying in clothing worn and setting depicted, followed by state measures of self-objectification, negative mood, body shame, and body dissatisfaction. It was found that the scenarios involving revealing clothing (bathers) led to greater state self-objectification, body shame, body dissatisfaction and negative mood than the scenarios involving more modest clothing (sweater), especially for heavier women. In addition, the dressing room scenarios led to greater state self-objectification but less negative mood than the public scenarios. It was concluded that clothing represents an important contributor to the body and emotional experience of contemporary young women.
