Emotion recognition and expression in young obese participants: preliminary study

This study of the presence of alexithymic characteristics in obese adolescents and preadolescents tested the hypothesis of whether they showed impaired recognition and expression of emotion. The sample included 30 obese young participants and a control group of 30 participants of normal weight for their ages. Stimuli, 42 faces representing seven emotional expressions, were shown to participants who identified the emotion expressed in the face. The Level of Emotional Awareness Scale was adapted for children to evaluate their ability to describe their emotions. Young obese participants had significantly lower scores than control participants, but no differences were found in recognition of emotion. The lack of words to describe emotions might suggest a greater prevalence of alexithymic characteristics in the obese participants, but the hypothesis of a general deficit in the processing of emotional experiences was not supported.     

The Exemption that Confirms the Rule: Reflections on Proceduralism and the UK Hybrid Embryos Controversy

This paper provides an interpretation of the licensing provisions envisaged under the Human Fertilisation and Embryology Act 1990 as a model for a rule and exemption-based procedural strategy for the adjudication of potential ethical controversies, and it offers an account of the liberal-democratic legitimacy of the procedure’s outcomes as well as of the legal procedure itself. Drawing on a novel articulation of the distinction between exceptions and exemptions, the paper argues that such a rule and exemption mechanism, while not devoid of attractions, is not immune from the criticisms often levied against procedural approaches to the management of pluralism: it either has to fall back on substantive justification in ways that are not helpful when trying to arbitrate a moral controversy, or it appears justificatorily groundless.     

Coding controlled and triggered cursor movements as action effects: influences on the auditory Simon effect for wheel-rotation responses

Four experiments investigated influences of irrelevant action effects on response selection in Simon tasks for which tone pitch was relevant and location irrelevant, and responses were clockwise- counterclockwise wheel rotations. When the wheel controlled left-right movement of a cursor in a direction opposite an instructed left-right hand-movement goal, the Simon effect was reduced. When the wheel was held at the bottom, this reduction was due to some participants coding responses relative to the cursor and others relative to the hands. However, when the wheel was held at the top, it was due to participants integrating cursor movements with hand movements as a single action concept. In contrast, a cursor triggered by the wheel movement showed little influence on the Simon effect, even when contiguity and contingency with the wheel movements were high. Experience with the controlled cursor in a prior trial block or between trials established a causal relation that enabled participants to code the triggered cursor as belonging to the action concept and thus reduce the Simon effect. Multiple factors determine the influence of an irrelevant action effect on performance.     

A comparative study of the impact of education vs. process groups for families of patients with affective disorders

This clinical project compares the relative impact of two types of multiple family groups on psychiatric inpatients and their families. Forty patients with a diagnosis of affective disorder, and their family members, were randomly assigned to a traditional multiple family group with a process orientation that emphasized support, destigmatization, and self-help about common problems; or to a psychoeducational multiple family group that emphasized the provision of information about the patient's illness and methods of coping with it effectively. Both groups, which met for four hours on a Saturday afternoon, were an integral part of an ongoing inpatient program specializing in the treatment of affective disorders. Pre- and post-measures were obtained regarding family and patient knowledge about affective disorders, level of personal distress, attitudes about the illness, and dyadic adjustment. In addition, both patients and family members were asked to rate their satisfaction with the group experience. A number of differences in knowledge, attitude and dyadic adjustment were found in the participants of both groups immediately following their respective group sessions, but there were only a few statistically significant differences between the two groups. Those who attended the psychoeducational session, however, reported significantly more satisfaction with the experience.     

Assessing outcome in smoking cessation studies.

Outcome measures for smoking cessation are reviewed and evaluated, including 3 self-report measures and 3 biochemical validation measures. Point prevalence reflects the percentage of participants taking action, prolonged abstinence reflects those in the maintenance stage, and continuous abstinence reflects those who progress from action to maintenance without lapsing or relapsing. Biochemical assessments are primarily measures of point prevalence abstinence. The desirability of biochemical validation is a particularly controversial and critical issue. Three factors affect the accuracy of self-report: Type of Population, Type of Intervention, and Demand Characteristics. False-negative rates are generally low. Three broad issues impact on decisions to use biochemical validation: (a) alternative explanations for false positives, (b) refusal rate problems, and (c) the effect of inaccuracy on intervention assessment.     

The stages and processes of exercise adoption and maintenance in a worksite sample.

We applied the model of the stages and processes of change to exercise adoption and maintenance. This model has shown promise in advancing theory and treatment of the addictions and other negative health behaviors, but there have been few systematic attempts to apply the model to positive health behaviors, such as exercise adoption. Questionnaires dealing with the stages and processes of exercise change were developed and administered to a sample of 1,172 participants in a worksite health promotion project. The sample was split randomly into halves for (a) initial model development and testing and (b) confirmatory measurement model testing. Additional model confirmation was obtained by examining the hierarchical structure of the processes of change and by conducting Stage x Process analyses. Results suggest that the underlying constructs derived from smoking cessation and other addictive behaviors can be generalized to exercise behavior. Understanding the stages and processes of exercise behavior change may yield important information for enhancing exercise adoption, adherence, and relapse prevention at both individual and public health levels.     

Blending qualitative and behavior analytic research methods to evaluate outcomes in inclusive schools

Following Haring's (1992) recommendation, we have utilized qualitative research techniques to assist us in designing a program of research on inclusive education which is responsive to the outcome values and priorities identified by teachers and parents. Using interviews, observations, and document analysis to follow 35 children in full inclusion classrooms over a period of two years, we have described outcomes for these children in three major domains. These outcome domains, and subthemes within them, have been evaluated and revised based on interviews and social validation ratings by parents and teachers. Dependent measures based on our qualitative research findings are currently being used in a series of behavior analytic studies designed to evaluate the effects of specific interventions on outcomes of inclusion for children with and without disabilities.     

Grouping students for instruction: effects of learning style on achievement and attitudes

The present study examined the effects of matching and mismatching American middle-school students with a preference for learning alone or learning with peers with selected instructional treatments in order to determine the impact upon their attitudes and achievement in social studies. Analysis revealed that the learning-alone preference performed significantly better in the learning-alone condition and that the learning-with-peers preference performed significantly better in the learning-with-peers condition. However, no-preference students also performed significantly better in the learning-alone condition than with peers. In addition, data revealed that the learning-alone and the learning-with-peers students had significantly more positive attitudes when matched with their preferred learning style; the nopreference students had more positive attitudes in the learning-alone condition.     

Debunking myths about self-quitting. Evidence from 10 prospective studies of persons who attempt to quit smoking by themselves

This article examines data from 10 longterm prospective studies (N greater than 5,000) in relation to key issues about the self-quitting of smoking, especially those discussed by Schachter. When a single attempt to quit was evaluated, self-quitters' success rates were no better than those reported for formal treatment programs. Light smokers (20 or less cigarettes per day) were 2.2 times more likely to quit than heavy smokers. The cyclical nature of quitting was also examined. There was a moderate rate (mdn = 2.7%) of long-term quitting initiated after the early months (expected quitting window) of these studies, but also a high rate (mdn = 24%) of relapsing for persons abstinent for six months. The number of previous unsuccessful quit attempts was unrelated to success in quitting. Finally, there were few occasional smokers (slips) among successful long-term quitters. We argue that quitting smoking is a dynamic process, not a discrete event.
