Cleaning the plate: food left by overweight and normal weight persons.

The amount of food left on trays after a clinner meal in a university cafeteria was measured for 146 persons. Half of the subjects were overweight and half were normal weight. Overweight women left significantly less food on their trays than did women of normal weight. Among men, the overweight also left less food but the difference did not reach significance. These findings suggest that food left over must be measured in estimating food intake from food choice, that behavior therapy injunctions to leave food on the plate are justified, and that obesity may be, at least in part, a result of learned patterns of behavior.     

Vocational development in early childhood: An examination of young children's expressions of vocational aspirations

Vocational aspirations were investigated in a sample of 282 children between the ages of 3 and 6. Age comparisons suggested that one aspect of vocational development in early childhood involves mastery of the task of projecting oneself into the future and conceiving of oneself as one day achieving adult status. Race comparisons indicated that urban blacks were less mature than urban whites in terms of mastery of the vocational projective task seen as characteristic of this developmental period. No significant sex differences were found in rate of development. However, there were indications that the pattern of vocational projection differs for males and females and that females undergo occupational foreclosure earlier than their male peers. Implications for vocational development theories are discussed.     

Does experienced pain affects local brain volumes? Insights from a clinical acute pain model

Background/Objective:To study pain-brain morphometry associations as a function of post-surgery stages (anesthesia, pain and analgesia) in an acute pain model. Method:Impacted mandible third molar were extracted. Before surgery, an anatomical T1 scan was obtained. Regional brain volumen and subcortical nuclei shapes were obtained. Statistical analyses were done using multiple regression, being pain scores the predictors and voxel volumes, subcortical nuclei volumes and subcortical nuclei shapes, the outcomes. Results:Pain was significantly larger at pain than at anesthesia and analgesia stages, and was higher during anesthesia than during analgesia. Pain intensity was related to grey matter in several cortical (Insula, Mid Frontal and Temporal Gyruses, Precuneus, Anterior Cingulate), and subcortical nuclei (Hippocampus, Thalamus, Putamen, Amygdala), depending of the post-surgical stage. A larger number of brain areas showed significance at pain that at anesthesia and analgesia stages. Conclusions:The relationships of regional brain volumes and subcortical nuclei shapes with pain scores seemed to be unsteady, as they changed with the patient's actual pain stage.     

Worker estimation of ability requirements of their jobs

A modified version of the Minnesota Job Requirements Questionnaire (MJRQ), representing the GATB aptitudes, was used by workers in 11 selected jobs to rate the ability requirements of their jobs. Worker MJRQ ratings were compared with supervisor MJRQ ratings. Modified Occupational Ability Patterns (OAPs) derived from worker ratings were compared with OAPs based on supervisor ratings, OAPs from expert ratings in the DOT, and OAPs from the empirical GATB approach. Reliability of worker MJRQ ratings was comparable to that of supervisor ratings. Comparisons of mean ratings and variability of ratings of workers in a job category with workers in other jobs, and with supervisors rating the same job, showed construct validity for worker MJRQ ratings, as did intercorrelations of the worker ratings. OAPs derived from worker MJRQ ratings compared favorably with OAPs derived from supervisor MJRQ ratings, from the DOT, and from the GATB. Differences among workers on variables such as satisfaction, age and tenure did not significantly affect their MJRQ ratings. Implications of the worker MJRQ ratings are discussed.
