Cognitive differentiation as a function of information type and its relation to career choice

Although providing occupational information is a common vocational counseling practice, recent research has raised questions about the utility of such information. Cognitive differentiation (the ability to differentiate among job titles on 12 constructs) has been shown to be positively related to an “appropriate” career choice. Differentiation, however, appears to decrease as a function of traditional types of occupational information (e.g., Occupational Outlook Handbook, U.S. Department of Labor, Washington, D.C., 1980). The present study investigated the hypothesis that information related to Holland personality characteristics of persons in various occupations would increase subjects' ability to differentiate among those job titles. One hundred fifty undeclared-major freshman undergraduate students were randomly assigned to one of three condition groups: objective information, personality information, no information. All subjects were administered the Career Decision Scale and Cognitive Differentiation Grid. Results indicated that subjects receiving personality information exhibited a significantly greater degree of differentiation among careers than subjects receiving objective information. These results confirm the major hypothesis of the study and suggest that the provision of personality information may be more useful in promoting career choice than the types of information traditionally provided.     

Dissociation between conditioned emotional response and extended avoidance performance

The present experiments examined the dissociation between the strength of a shuttlebox avoidance response (AR) and one index of fear of the avoidance CS. Avoidance response strength was indexed by resistance to extinction of the AR and by changes in response latency, and fear of the CS was indexed by the conditioned emotional response (CER) technique. Experiments 1, 2A, and 3A all found that rats trained to a criterion of 27 consecutive avoidance responses (CARs) showed response strength comparable or superior to rats trained to a criterion of 9 CARs. Experiments 2B and 3A demonstrated that rats trained to 27 CARs showed less suppression of bar pressing during the avoidance CS (less CER) than rats trained to 9 CARs. Experiment 3A also found that, when extinguished in the shuttlebox to a moderate criterion (5 consecutive trials without a response) before CER testing, rats trained to 9 CARs showed some, although not complete, loss of CER, whereas rats trained to 27 CARs showed no loss of CER. In Experiment 3B rats that took 1 vs 2 days to reach a criterion of 27 CARs were compared for their AR strength and for their CER. Although rats taking 2 days to reach criterion showed somewhat greater resistance to extinction of the AR than rats reaching criterion in 1 day, this variable had no apparent effect on the CER. Implications of the present results for current theories of avoidance learning are discussed.     

Preference as a function of the correlation between stimuli and reinforcement outcomes

Pigeons' preferences for stimuli that were to varying degrees correlated with outcomes were studied in two experiments using a concurrent-chain procedure. The pigeons chose between two terminal links, each ending with food reinforcement and with blackout on half of the trials. In the first experiment, one terminal link (nonpredictive or unreliable link) provided stimuli completely uncorrelated with the outcomes while the other terminal link (predictive or reliable link) provided stimuli that were, to varying degrees, correlated with these outcomes. All pigeons showed increasing preferences for the predictive link as the reliability of the stimuli in that link increased. In the second experiment, stimuli in both terminal links were differentially correlated with the outcomes. The pigeons again preferred the more reliably correlated terminal link. The relation between these results and the delay-reduction hypothesis and conditioned reinforcement account is noted. The behavioral value of predictive stimuli may lie in their permitting the organism to more effectively apportion its time between interim activities and terminal responses.     

A reinforcement plus interruption method of eliminating behavioral stereotypy of profoundly retarded persons

Stereotyped responses have been shown to be eliminated by an overcorrection-reinforcement program. The present study evaluated response-interruption as an alternative to the overcorrection component with seven profoundly retarded adults. During the baseline praise condition, stereotypy occurred during 66% of the observations for the seven profoundly retarded adults but decreased to less than one response per half hour in a mean of two sessions of individual training. In the subsequent class situation, stereotypy was reduced to less than 5% on the first day of class, to less than 1% by the fourth day and less than one stereotypy per hour after the third day. The interruption method seems preferable to postural overcorrection because of its apparent and relative nonaversiveness.     

Children's cognitive maps of large-scale spaces: Effects of exploration,direction, and repeated experience

Kindergarteners and third graders (mean ages 5–10 and 8–9 years) repeatedly encountered a model town and then constructed the town from memory. In Experiment 1, the effect of different types of exploration on the development of a cognitive map was assessed. Children who were directed to walk within the town placed buildings more accurately than children who had walked along the town's perimeter. Children who walked within the town and were directed to the spatial relationships among buildings had the highest placement accuracy. Third graders were more accurate than kindergarteners across the three types of exploration. In Experiment 2, children were permitted to explore the town alone for an unlimited amount of time. Under these conditions, third graders still placed buildings more accurately than kindergarteners. A comparison of Experiments 1 and 2 indicated that children developed more accurate cognitive maps when motor activity and attention were directed by the experimenter as opposed to being directed by the child. Accuracy improved with repeated walks and constructions in both experiments, and the results of Experiment 3 suggested that constructing facilitated the development of the cognitive map as much as walking. It was concluded that third graders' cognitive maps were more accurate than kindergarteners' maps due to differences in the speed of acquisition and storage of spatial information.     

Patterns of spontaneous recovery in aphasic groups: A study of adult stroke patients

The recovery of 31 aphasic stroke patients in the first three months postonset was investigated. Improvements on eight comprehension, repetition, and expression tasks were documented for four groups. These groups, retrospectively defined on the basis of initial scores on a fluency and a comprehension task, were: Low Fluency/Low Comprehension (LFLC), Low Fluency/High Comprehension (LFHC), High Fluency/Low Comprehension (HFLC), and High Fluency/High Comprehension (HFHC). Examination of each group's recovery revealed (1) equal improvement on nearly all language tasks for the two High Comprehension groups and (2) a more selective improvement largely in comprehension and imitation tasks for the two Low Comprehension groups. Implications of this selective improvement in initially low comprehending aphasics are discussed.     

Women's self-estimates of competence and the resolution of the career/home conflict

Relationships among women's role factors, self-estimates of competence, and career commitment were investigated. Eighty female business students and 111 business alumnae completed the Attitudes Toward Women Scale, the Performance-Self-Esteem Scale (PSES), and questions regarding home and career choices. As predicted, PSES scores were related to extent of career commitment, and PSES scores mediated the relationship between career commitment and women's role factors. Among high PSES subjects, career commitment was positively related to nontraditional sex-role attitudes and negatively related to family involvement. Among low PSES subjects, the relationship between career commitment and women's role factors was weaker. Implications for women's career development are discussed.     

Impressions of the Church of Sweden: liberal and catholic with nuances of Lutheranism

The Church of Sweden is difficult to describe or to characterise, whether as a Folk Church, a national church, as catholic or liberal, or as, in some sense, Lutheran. This article refers to aspects of its complex relations with the Roman Catholic Church and with Lutheranism at large. The author detects, from ecumenical agreement and practice, an incipient new communion of churches, based on a common claim to be catholic and also to be open to developments in society. This group includes the Church of Sweden, the Church of England, the Episcopal Church in the USA, the Old Catholic Churches of the Union of Utrecht and the Philippine Independent Church, all of which are in communion with each other. The author's presentation is set out in relation to the Church of Sweden's liturgical and sacramental life, its church–state relations, and in an account of the rather asymmetrical shape of ecumenism in Sweden, in all of which the question of gender plays a role.     

Probability learning and coping in dysphoria and obsessive-compulsive tendencies

The processing of stress-relevant categorical events and their contributions to subsequent probability judgments were examined among subjects who were psychometrically categorized as dysphoric, obsessive-compulsive, or “control.” stress-relevant symptomatology of depression was considered to be characterized by a deficit of active counterstress coping activity and obsessive-compulsiveness by ritualistic efforts which have little or no direct effect on stress occurrence. Subjects were presented with a sequence of stressful (loud white noise) and benign (illumination of a green light) events in association with a series of discrete stimuli (alphabetic letters) in three conditions of counterstress activity. Results generally supported the predicted tendency to learn probability information primarily in conditions which reflected the subjects' characteristic ways of responding to stress. Obsessive-compulsives acquired the information primarily in a “ritualistic” context, controls in an active coping context, and dysphorics in both a coping deficit context and unexpectedly in an active coping context. The role of enhanced stressor predicability in maintaining typical stress response patterns of the three groups was discussed.
