Dysfunctional body investment versus body dissatisfaction: Relations with well-being and controlled motivations for obesity treatment

In this study, we investigated the associations between body image and psychological well-being, exploring the mediating role of controlled regulation for entering obesity treatment. In addition, we analyzed whether investment body image was more strongly associated with controlled regulation (and subsequent well-being) compared to evaluative body image. These analyses were performed controlling for baseline BMI effects. Participants were 139 overweight women (age: 38.0 ± 6.7 year; BMI: 32.0 ± 4.1 kg/m²) entering treatment. Evaluative and investment body image, controlled regulation, and psychological well-being were assessed. Body image investment was positively associated with controlled regulation; evaluative body image was not. Controlled regulation was negatively associated with self-esteem and psychological functioning. Controlled regulation partially mediated the effects of body image investment on self-esteem, but did not mediate its effects on psychological functioning. Results suggest that dysfunctional body image investment might undermine well-being within overweight women, partly by increasing controlled regulation for entering obesity treatment. Discussion focuses on the importance of enhancing body image and autonomy during treatment to improve well-being and weight outcomes.     

Space-, object-, and feature-based attention interact to organize visual scenes

Biased-competition accounts of attentional processing propose that attention arises from distributed interactions within and among different types of perceptual representations (e.g., spatial, featural, and object-based). Although considerable research has examined the facilitation in processing afforded by attending selectively to spatial locations, or to features, or to objects, surprisingly little research has addressed a key prediction of the biased-competition account: that attending to any stimulus should give rise to simultaneous interactions across all the types of perceptual representations encompassed by that stimulus. Here we show that, when an object in a visual display is cued, space-, feature-, and object-based forms of attention interact to enhance processing of that object and to create a scene-wide pattern of attentional facilitation. These results provide evidence to support the biased-competition framework and suggest that attention might be thought of as a mechanism by which multiple, disparate bottom-up, and even top-down, visual perceptual representations are coordinated and preferentially enhanced.     

Telehealth for persons with severe functional disabilities and their caregivers: facilitating self-care management in the home setting

Persons with severe functional disabilities are the highest users of health care services. Caring for the needs of this population represents a significant percentage of our national health care costs. A growing body of research has demonstrated the efficacy of self-management strategies and caregiver engagement for effective long-term care for individuals with chronic medical conditions. Economic forces over the past decade have led to new challenges and resulted in major changes in health care delivery resulting in shortened length of inpatient stays and greater limits on the length of outpatient treatment. Telehealth is an innovative method for health care delivery and a means of meeting this new challenge. This article highlights the findings of 3 pilot studies on the use of telecommunications technologies in promoting self-care management and enhancing health care outcomes in persons with severe disabilities and their family caregivers. The importance of matching technology to the needs of this population, lessons learned from these investigations, and future directions for research are addressed.     

PUNISHMENT OF SELF-INJURIOUS BEHAVIOR USING AROMATIC AMMONIA AS THE AVERSIVE STIMULUS

Punishment with aromatic ammonia was used to eliminate self-injurious behavior of an autistic woman during experimental sessions. The effects were reversible but were limited to experimental sessions until staff used the ammonia on the ward at all times.     

Students' perceptions of female professors

This paper examines student attitudes towards academic women. The literature on females in male-dominated professions suggests that clients resent their authority, deny their competence, and accord them less prestige than men. One hundred and eighty one university students evaluated professors in terms of 21 semantic differential scales and an occupational prestige ranking instrument. Contrary to expectation, female professors were perceived as more competent than male instructors in both task and socio-emotional competence. Further, the males were not assigned a significantly higher prestige score. Despite Goldberg's (1968) conclusion that females are prejudiced against their own sex, the attitudes of the female students were the more favorable.     

Human neuropsychology: Some differences between korsakoff and normal operant performance

Summary Operant reinforcement schedules were used to investigate the effects of changes in reinforcement rates on the behavior of alcoholic Korsakoff (amnesic) patients and normal control subjects. In one test, both groups were exposed to pairs of variable-interval (VI) reinforcement schedules which operated concurrently. The distribution of reinforcements controlled the distribution of responses of normal subjects to a significantly greater extent than those of the Korsakoff patients. In a second test, two VI reinforcement schedules were arranged to run one at a time in succession. Reinforcement-rate differences with the successive (multiple) schedules did not produce corresponding response-rate differences for either group of subjects. The findings stress the complexity of the alcoholic Korsakoff syndrome, and emphasize the need to consider possible motivational abnormalities as determinants of alcohol-induced amnesia. In addition, results underscore both the value and the limitations of using operant procedures in human learning research.Supported in part by PHS Grants NS 07615 and NS 06209, by PHS RCDA K04 NS 00161 to M.

Assessing the specific psychopathology of binge eating disorder patients: Interview or self-report?

Research addressing the assessment of binge eating and associated eating disorder psychopathology has steadily increased in recent years. Few studies have examined the relationship between the various assessment methods. This study compared an investigator-based interview, the Eating Disorder Examination (EDE), with a self-report version of that interview, the EDE-Q. Fifty-two individuals (six men and 46 women) with binge eating disorder (BED) completed both instruments. Modest-to-good agreement and significant correlations (P < 0.0001) were found between the two methods on all four subscales assessing specific eating disorder psychopathology (i.e., Restraint, Eating Concern, Weight Concern, and Shape Concern subscales). However, higher levels of disturbance were consistently reported on the EDE-Q than the EDE interview. The two methods were not significantly or reliably related to one another when assessing binge eating. This may be due in part to the difficulty inherent in identifying binges in subjects with BED. Examination of individual item scores suggest that it might be possible to improve the performance of the EDE-Q by clarifying the definitions of certain complex features, although this should not be at the expense of compromising the practical utility of its self-report format.     

Effects of concurrent verbal rehearsal and temporal set upon judgements of temporal duration

Subjects (N = 252, college students) rehearsed a 30-item free-recall list, or rested for one of three intervals (32, 42 or 54 sec), on the first, third, or ninth study trial. At the conclusion of the interval, subjects made an absolute judgement of interval duration. Half the subjects were informed that this time judgement would be required prior to the interval (prospective), and the remainder were not informed of the required time judgement until after the interval (retrospective). As the number of previous trials increased, judged time (1) increased linearly in the prospective-rehearsal group, (2) decreased linearly in the retrospective-rehearsal group, and (3) had no effect on the nonrehearsal groups. Prospective judgements were greater than retrospective. It was concluded that retrospective time judgements are a function of the amount of information the subject remembers having processed during the interval.     

Moderate Aerobic Exercise, T'ai Chi, and Social Problem-Solving Ability in Relation to Psychological Stress

This study evaluated the importance of exercise mode, social problem-solving ability, gender, and age in relation to anxiety and perceived daily hassles. Adult participants were classified as moderate aerobic exercisers, T'ai Chi exercisers, or sedentary via completion of a questionnaire. Social problem-solving ability, state and trait anxiety, and frequency and severity of daily hassles were measured. As predicted, scores indicating effective social problem-solving ability were associated with fewer reported severe daily hassles and with lower scores on state and trait anxiety. For state and trait anxiety, a main effect of exercise mode emerged after age and gender were controlled. A 3-way interaction involving age, gender, and exercise mode suggested that age and gender moderate the effects of exercise on anxiety, that is, the stress-reducing efficacy of different exercise modes may be dependent on a person's age and/or gender. Implications for theory, research, and practice are discussed.
