Four dialogue systems

The paper describes four dialogue systems, developed in the tradition of Charles Hamblin. The first system provides an answer for Achilles in Lewis Carroll's parable, the second an analysis of the fallacy of begging the question, the third a non-psychologistic account of conversational implicature, and the fourth an analysis of equivocation and of objections to it. Each avoids combinatorial explosions, and is intended for real-time operation.     

The impact of school emotional climate on student psychopathology

Reports of differences among schools in emotional and social climate were related to changes in behavioral and emotional problems and alcohol use in students who remained in these schools over a 2-year interval. Four dimensions of school climate were examined. School conflict and social facilitation were shown to be related to increases in childhood psychopathology, whereas student autonomy was not. Effects of academic focus were even stronger than those of conflict, in the sense of being independently related to more syndromes. School climate effects were examinedfor conditionality on student characteristics and for synergism, It was concluded that intervention to alter the school climate may promote the emotional and behavioral well-being of children and adolescents.This research was supported by NIMH Grants MH36971 and MH30906. The authors wish to thank Robert Ouellette for his assistance.     

On knowing when to quit: Task failure, self-esteem, advice, and nonproductive persistence

Past research has found the performance of persons with high self-esteem to improve after failure, especially on tasks for which persistence correlates positively with performance. However, persistence may be nonproductive in some situations. Experiment 1 used a task for which persistence and performance were uncorrelated; subjects high in self-esteem persisted longer but performed worse than did those with low self-esteem, particularly after prior failure feedback. Experiment 2 tested whether differential sensitivity to advice about the efficacy of persistence mediates nonproductive persistence. High self-esteem subjects who received explicit advice against nonproductive persistence on a puzzle-solving task still tended to persist longer on unsolvable puzzles than did low self-esteem subjects. The implications of high self-esteem subjects' tendency to engage in nonproductive persistence are discussed.     

The training of telephone crisis intervention volunteers

Telephone crisis intervention services are growing at a very rapid rate. A review of the literature reveals that there are very few references to this new phenomenon and even fewer that deal with evaluating the effectiveness of telephone crisis training. Herein 7 articles are reviewed which deal with volunteer selection and training. These articles demonstrate that no consistent rationale for volunteer selection or training exists. Selection of volunteers typically consists of a gross screening to eliminate any obviously unsuitable persons, with training serving as a further sorting procedure where volunteers who are uncomfortable with the role of a crisis interventionist can be encouraged to drop out. The authors suggest that a training model be built around crisis intervention theory using principles of social learning as the methodology for training.     

Job Evaluation and Gender: The Case of University Faculty

This study examined the effects of students' and professors' sex on student evaluations of professors' teaching effectiveness. Ratings of over four hundred faculty made by over nine thousand students were analyzed. After controlling for a large number of variables, the main results showed that (a) male faculty were given significantly higher evaluations on global teacher effectiveness and academic competence than female faculty; (b) when controlling for extraneous variables, female faculty were not found to be rated as more sensitive to student needs than male faculty; and (c) when making overall, global judgments of faculty performance, students seem to place more weight on academic competence for male faculty than for female faculty.     

Clinical construction of action social networks

The author describes his ten year experience in the development of action social networks as a clinical intervention technique. This involves up to 30 persons who are currently significant in the patient's life situation. Practical, fiscal, clinical, and ethical issues are raised. The author finds that social network paradigms are most important in conceptualizating clinical care, but are now more conservative in clinical network intervention.     

Categorical and spatial modes of representation in young children's recall

Preschool children aged 4 and 6 were asked to recall a set of line drawings under two conditions: pictures blocked in category groups, and pictures blocked in noncategory groups. For 4-year-olds, the blocking condition made no difference in the structure of their recall; but for the 6-year-olds, the category blocking served as a support for category clustering of their recall lists. No purely spatial clustering appeared at either age. It was concluded that 6-year-olds' use of classes is closely linked to concrete spatial arrangement of objects.     

Two components of need for approval score and their relationship to cheating following success and failure

Subjects completed a simulated “intelligence test” on which they were given bogus feedback indicating that they had either met college norms or had failed substantially to meet norms. Immediately following was a period in which subjects could modify their scores and believe that their modification would go undetected. The relationship of need for approval to “cheating” and amount of “cheating” was analyzed. The results supported an “avoidance” interpretation of approval motivation. Two separate components of need for approval score were identified and found to be differentially related to avoidance behavior for men and for women.
