Inferences of mental illness from noninvolvement

These studies continue the exploration of variables related to a person's use of the mental illness categorization. The central concern in the present studies was the effect of perceived variation in a target person's level of involvement in a social situation. While a low level of involvement, as portrayed in videotaped scenarios, prompts attribution of mental illness, other features of implicit personality theories also relate to greater or lesser attribution of mental illness. Those participants who gave evidence of having attributed lower levels of involvement, regardless of filmed information, also attributed higher levels of mental illness. Social workers, compared to general population participants, attributed higher levels of mental illness at all levels of target involvement. We discuss the implications of these findings for dissemination and assignment of the mentally ill role.     

TV heroes: The impact of rhetoric and deeds

Two experiments examined the influence of children's cartoons and their prosocial messages on the behavior and judgments of kindergarten, second, and fourth grade children. Three conditions or types of programs were used: purely prosocial (moral lesson but no aggression); and purely aggressive (no moral lesson). Behavioral, evaluative, and comprehension measures were taken. All children were able to distinguish the protagonist and antagonist. Older children grasped the implications of the stories but younger children, especially those in the prosocial/aggressive condition, did not. Scores of children in the prosocial/aggressive condition were significantly lower on message comprehension than those of subjects in the purely prosocial condition. Implications for the relationship of behaviors (prosocial actions) to judgments, portrayal of aggressive heroes on television programs, and the acceptance of aggression as normative behaviors, are discussed.     

Sex differences: A study of the ear of the beholder

Male and female adult Ss, while performing an unrelated task, heard a single infant awakening. The infant was labeled a girl or a boy. The dependent variable was how quickly Ss responded to the crying infant. Females responded more quickly to the girl than to the boy. Males responded equally slowly to boy and girl. A questionnaire on sex differences in fragility showed that females and males tend to disagree with the proposition that girls are more fragile than boys. Thus, the females' faster response to a crying girl cannot be accounted for by a belief in sex-differential fragility. Correlations between fragility beliefs and response times to an infant indicate that sex-differential belief-behavior relationships are not the same for males and females.     

The illusion of knowing: Failure in the self-assessment of comprehension

The illusion of knowing is the belief that comprehension has been attained when, in fact, comprehension has failed. In the present experiment, the illusion was defined operationally as having occurred when readers who failed to find a contradiction in a text rated their comprehension of the text as high. Texts containing contradictions between adjacent sentences were presented, and readers were explicitly asked to search for contradictions. The frequency of illusions was greater when the contradictory sentences came at the end of three-paragraph texts rather than at the end of one-paragraph texts and when the contradictory information was syntactically marked as new. These results are interpreted within a framework that emphasizes that the goal of reading expository text is to establish coherence within and among sentences. In addition, the results are apparently incompatible with the notion that readers engage in active and accurate on-line monitoring of the degree to which this goal is met.     

Test performance and social comparison choices of high school men and women

The present research was designed to investigate whether anticipated publicity of performance would adversely affect the performance of high school girls to a greater extent than high school boys. If ambivalence about success is intensified for girls towards the end of high school, they would be expected to do better when test results were anticipated to be private rather than public. These results were confirmed only for girls of average ability. Average-ability girls also chose same-sex comparisons and showed less interest in comparison with standard setters. Performance data and social comparison choices suggest that the pattern of achievement for average-ability girls may be well established by sixth grade. Further clarification of the period when incompatibilities arise between the female role and academic achievement is required.Portions of this article were presented as a paper at the annual meeting of the Midwestern Psychological Association, Chicago 1977, and formed part of the first author's research for her master's thesis, submitted to Indiana University, 1976.     

Growth functions for rapid remembering

Children between ages 9 and 13 were tested for recognizing and remembering words from 6- and 12-word lists. Opportunities for using deliberate mnemonics were severely restricted. Developmental functions showed different growth patterns for remembering the items in a short list than for remembering order, and different patterns for storing items from a long list than for retrieving them. However, none of these functions was parallel to the growth function of rapid word recognition. This absence of parallel growth contradicted a hypothesis that memory develops when item recognition develops. The data suggested, instead, that modest but reliable gains in rapid processes of storage and retrieval contribute to memory development during middle childhood.     

A computer-oriented task analysis method for mathematics instruction

Components of a computer solution for fraction problems in arithmetic have an analog in a new approach to educational task analysis. The components may be called goal-setting or planning elements, in contrast to the goal-satisfying or behavioral steps emphasized in much contemporary task analysis. A hypothetical tutorial dialogue in which a student is asked to tell a tutor what step to perform next is presented as an example of the emphasis of the planning side of computation. Explicit identification of goal-setting elements of a task is illustrated by analysis of the task of converting a pair of fractions to a new pair with a common denominator. The decomposition thus produces is simulated with two computer programs: (1) a LISP program using a set of production rules consisting of conditions to be met and subsequent actions to be taken and (2) a PROLOG program stating goals and solving goals explicitly.     

Changes in orienting and habituation in the rat following administration of chlorpromazine

Chlorpromazine (0.5-3.0 mg/kg) significantly reduced orienting to a novel auditory stimulus, but subsequent habituation after repeated presentations of the stimulus was not prevented nor significantly impaired. These results support the suggestion that the mechanisms underlying orienting and habituation are independent.
