Conditioned and unconditioned caloric compensation: Evidence for self-regulation of food intake in young children

The purpose of these two experiments was to determine (a) whether young children can be responsive to caloric density cues in regulating their food intake, (b) whether such cues can be associatively conditioned to organoleptic cues in foods, and (c) to obtain evidence regarding which of the many cues available are involved as conditioned stimuli. In Experiment 1 participants were eighteen 3- to 5-year-old children, who were seen for a series of pairs of conditioning trials, followed by extinction test trials. Each trial consisted of a two-part snack: approximately 100 ml of a pudding preload (chocolate or vanilla; high or low caloric density) followed after a delay by ad-lib consumption of snack foods (cookies and crackers). In extinction trials, flavors previously paired with high- or low-caloric density preloads during conditioning were presented in isocaloric intermediate density preloads. Results indicated that 14 of 18 children showed unconditioned caloric compensation on the first pair of conditioning trials; 16 of 18 children showed compensation following the second pair of trials, and 12 of these 16 subjects continued to show this consumption pattern during extinction. Consumption was significantly greater following the low calorie paired flavor than following the high calorie paired flavor during extinction. Experiment 2 (N = 10) replicated these findings, and uncorrelating preload and snack food flavors indicated that flavor cues in the preloads can serve as conditioned stimuli. Children showed both initial responsiveness to caloric density and evidence for associative conditioning of food cues to the physiological consequences of eating. These results provide initial evidence for a mechanism allowing the child to learn to anticipate the caloric consequences of familiar foods and regulate food intake accordingly.     

Informational cues and attributions based on role behavior

A recent experiment by Messick and Reeder (Journal of Experimental Social Psychology, 1972, 18, 482–491) attempted to extend Jones, Davis, and Gergen's (Journal of Abnormal and Social Psychology, 1961, 63, 302–310) classic finding that out-of-role behavior.is more informative for person perception than in-role behavior. It is argued, however, that this study confounded two variables, role performance and occupation. Evidence is presented that the occupation variable alone could have produced Messick and Reeder's results. Both variables seem to affect attributions. The importance of these findings for relating attribution theory and role theory is discussed.     

Baseline differences,attention, and age differences in time-sharing performance

The purpose of this experiment was to determine whether age differences noted when two tasks are performed concurrently can be accounted for in terms of age differences in single task baseline performance. Two groups of 12 8-year-olds and one group of 12 13-year-olds performed a compensatory tracking task and an auditory matching task, first alone and then time shared. The 8- and 13-year-old baseline groups performed baseline trials on each task prior to time-sharing trials. Each training group 8-year-old was randomly paired with a 13-year-old and given sufficient single task practice before time sharing to equate the 8- and 13-year-old pair members' baselines on both tasks. Results showed trained 8-year-olds to be indistinguishable from 13-year-olds in time sharing, whereas the 8-year-old baseline group showed significantly greater decrements in time-sharing and higher baseline scores on both tasks. These data provide support for the hypothesis that time-shared performance is directly related to level of baseline performance.     

Training strategic study time apportionment in educable retarded children

Two groups of educable retarded children differing in functioning level served as subjects. One group, the High group, consisted of 31 children drawn from the upper two classes of a five-class stream. The Low group consisted of 39 children drawn from the lowest two classes. During pretesting, on each trial but the first of a multitrial free recall procedure, subjects were allowed to select half of the to-be-remembered items to see if they would strategically select missed items for extra study. Following pretesting, subjects were divided for training into three groups for which the experimenter selected items for study: in the Standard group, missed items; in the Creeping group, recalled items plus one missed item; and in the Random group, half missed and half recalled items. Children in the High group improved in the Standard condition, and those in the Low group benefited from Creeping training. There was no evidence of maintenance of training in the Low group, but children in the High group given training in the standard strategy selected missed items for recall on the posttests. The results are discussed in terms of the stability of trained strategies in retardates, and the question of what constitutes an optimal strategy is considered.     

On putting apples into bottles — A problem of polysemy

An experiment was designed in such a manner that a sentence could be recalled given a certain cue only if the subject's encoding of the sentence included details and involved distinctions in the senses of words which could not have been part of the correct dictionary readings for these words. The most plausible interpretation of the results is that comprehension of a sentence entails constructing a particularized and elaborated mental representation, and that this process depends more heavily on knowledge of the world and analysis of context than is generally appreciated. It is claimed that existing associative or semantic network theories would be strained to accommodate the data.     

Environmental,background, and psychological variables related to optimizing achievement and career motivation for high school girls

The purpose of the study was to investigate some environmental and psychological variables related to optimizing the achievement strivings of high school girls. It was hypothesized that environmental and psychological variables would have significant relationships to achievement strivings. The criterion variables were career motivation and achievement motivation. The predictor variables were: community support, early family socialization (environmental), self-esteem, risk preference, sex role orientation, and fear of success (psychological). Subjects were 10th-grade girls (N = 158) in a suburban midwestern high school district. Procedures involved group test administration involving 2 hr during the regular school day. Multiple regression analysis indicated that high achievement motivation and career choice were significantly associated with perceived support for achievement and career goals in the school and community environment (p < .01). Implications for increasing achievement and career motivation were discussed in relation to the requirements of the Education Amendments of 1972 and 1976 (Title IX).     

Self-esteem and job complexity as moderators of performance and satisfaction

Self-esteem and job complexity were investigated as moderators of self, supervisor, and peer ratings of performance and satisfaction with work, supervisors, and peers testing balance and activation theories. One hundred and fifty-three registered nurses served as subjects. Measured self-esteem was not significantly related to the performance or satisfaction measures. Rather, the important variable was perceived job complexity as predicted by Scott's activation theory. Self-ratings of performance and satisfaction with work and peers were greatest at optimal complexity with lower values at high and low complexity. Some support was found for self-esteem as a moderator of the relationship between performance and satisfaction measures in line with Korman's formulations.
