In a series of studies, subjects were asked to make predictions about target individuals. Some subjects were given information about the target which pretest subjects had judged to be “diagnostic”—that is, had judged to be usefully predictive of the outcome. Other subjects were given a mix of information judged to be diagnostic and information judged to be “nondiagnostic” by pretest subjects—that is, judged to be of little value for predicting the outcome. Subjects given mixed information made much less extreme predictions than did subjects given only diagnostic information. It was argued that this “dilution effect” occurs because people make predictions by making simple similarity judgments. That is, they compare the information they have about the target with their conception of outcome categories. The presence of individuating but nondiagnostic information about the target reduces the similarity between the target and those outcomes that are suggested by the diagnostic information. One of the major implications is that stereotypes and other “social knowledge structures” may be applied primarily to abstract, undifferentiated individuals and groups and may be largely set aside when judgments are made about concrete, individuated people. 相似文献

This paper presents an empirical study of sex differences and sex-role stereotyping in clinical psychologists' reports. The results of numerous analyses showed no significant evidence at any point of sex differences or sex-role stereotyping in the form or the subject matter of the clinical reports.

Cerebral laterality was examined for third-, fourth-, and fifth-grade deaf and hearing subjects. The experimental task involved the processing of word and picture stimuli presented singly to the right and left visual hemifields. The analyses indicated the deaf children were faster than the hearing children in overall processing efficiency, and that they performed differently in regard to hemispheric lateralization. The deaf children processed the stimuli more efficiently in the right hemisphere, while the hearing children demonstrated a left-hemisphere proficiency. This finding is discussed in terms of the hypothesis that cerebral lateralization is influenced by auditory processing. 相似文献

Two experiments examined the early development of selective information use in search. The first experiment tested 9- and 16-month-olds on a modification of Piaget's Stage IV object permanence task. It examined infants' use of information from previous experiences with an object (prior information) and from the most recent hiding (current information) to locate a hidden object. In the second experiment, 2-, -, and 4-year-old children received these same sources of information along with new forms of prior and current information: information about the typical locations of objects (location specificity) and verbal information. No systematic perseveration was observed at 9 months, although previous findings related to perseveration were replicated. Perseveration was found at 16 months, but there was also evidence of selectivity at that age. When errors occurred, they tended to be to the prior location, but they were infrequent in comparison to correct searches at the current location. The preschoolers, while continuing to show perseveration, were more consistently selective than the infants. They also showed considerable generality in extending their selectivity to new sources of information. 相似文献

The purposes of this study were to (1) describe errors in weightbearing at three target levels for patients with neuropathic feet and control subjects, (2) compare the absolute errors at the three target levels between groups, and (3) identify predictor variables of errors in weightbearing by the neuropathic group. The groups of 26 subjects were matched for age and height. Weightbearing was measured with digital scales while subjects attempted to adjust their weight through a designated lower extremity to each target level (25, 50, and 75% of body weight). Analysis of variance indicated no significant difference in the percentage weightbearing between groups at the three target levels. There was a significant difference in errors made in weightbearing by the groups at the three target levels. Mean errors ranged from 8.5 to 9.7% for the neuropathic group and from 2.4 to 6.6% for the control group. The findings cast doubt on the utility (in the absence of feedback) of requesting individuals, particularly those with neuropathic feet, to weightbear at specific target levels. 相似文献

Five instruments, the Differential Test of Conduct and Emotional Problems, Louisville Behavior Checklist, Personality Inventory for Children, 16 PF Test, and Tennessee Self-concept Scale, were given to differentiate between 50 conduct problem and 48 emotionally disturbed students assigned in public school to secondary level classes for the severely emotionally handicapped. Discriminant analysis of each test's rate of classification germane to both a pre-assessment categorization as conduct problem vs emotionally disturbed and a post-assessment classification as no problem vs conduct problem vs emotionally disturbed vs combined problem is presented. The analysis indicated that the Differential Test of Conduct and Emotional Problems, Louisville Behavior Checklist, and Personality Inventory for Children can, with variable effectiveness, significantly classify adolescents into groups using such pre- and post-assessment information. 相似文献

In two experiments, we investigated the relationship shared by irrelevant thoughts, emotional mood states, and cognitive task performance. At an empirical level, irrelevant thoughts were defined as thoughts that did not facilitate successful task performance. We used the same general procedure for both experiments: three groups of college students received happy-, neutral-(control), or sad-mood inductions and performed a memory task. The procedure for obtaining thoughts varied between experiments. The subjects in Experiment 1 listed their thoughts after the memory recall task. In Experiment 2, the subjects were tape-recorded while performing a memory task and producing concurrent verbal protocols. The subjects in both experiments then judged their thoughts in terms of frequency, intensity, and irrelevance. We found a similar pattern of results in both experiments: (1) The proportions of irrelevant thoughts and recall performance were negatively related, and (2) happy and sad students produced reliably greater proportions of irrelevant thoughts than did neutral (control) students. 相似文献

Forty-one Protestant ministers completed measures of stress-related symptoms, family of origin contact, church governing body density, history of pastor-parish conflict in the church, and a measure of Bowen's (1959b/1985) concept of emotional triangles. A denominational executive provided ratings of each church's history of pastor-parish conflict. Path analysis using multiple regression showed support for a model in which governing body density and history of conflict predicted emotional triangles, and emotional triangles predicted stress symptoms. Contact with the pastor's family of origin moderated the relationship between emotional triangles and stress symptoms. Results suggest that the organizational and family ecology of the ministerial role can be important in understanding occupational stress among ministers. 相似文献

The interactions and perceptions of two groups of divorcing parents using different dispute resolution processes were compared at final divorce and at 1 and 2 years post-divorce. Using objective and standardized measures, the effectiveness of a comprehensive divorce mediation process was contrasted to the more customary two attorney adversarial process. The 153 parents at final divorce were part of a larger, longitudinal study of 435 divorcing men and women who were followed from the beginning of divorce to 2 years post-divorce. Parents in the divorce mediation group reported less conflict during the divorcing period, and less conflict, more contact and communication, and a more positive attitude toward the other parent at final divorce, results which remained significant after controlling for several baseline group differences. The majority of differences favoring the mediation intervention continued through the first year after divorce, and disappeared by the 2 year post-divorce data collection. The nature of the mediation process is discussed in relation to these parental behaviors and attitudes. 相似文献
