Many state agencies have ruled that assignment of students to special education classes for the mentally retarded must be determined by assessment of verbal, performance, and adaptive behaviors. The AAMD Adaptive Behavior Scale: Public School Version was subjected to a normative and validation study using 291 subjects from the southcentral area of Texas. Data were collected from groups of regular and special education students, both white and nonwhite, at 8, 10, and 12 yr. of age. Results were compared to the original normative data provided in the AAMD manual and indicated that (1) the instrument is effective in discriminating between regular and special education groups; (2) a shortened version may be feasible and more practical; and (3) the derived total score may be useful and effective when used as a cut-off score for placement in special education for the mentally retarded.  相似文献

In an experiment to study the effects on attitudes of requiring subjects to use evaluatively biased language, 84 schoolchildren aged 13–14 years completed a questionnaire to measure their attitudes on the issue of adult authority over teenagers, before and after writing an essay on this issue in which they were either required to incorporate words from a list all of which implied a positive evaluation of a pro-authority position or a negative evaluation of an anti-authority position (pro-bias condition), or required to incorporate words where the implied evaluations were reversed (anti-bias condition), or were given no words to incorporate (control condition). Relative to controls, pro-bias subjects showed as a shift towards a more pro position and anti-bias subjects became more anti irrespective of their initial attitudes (pro-bias versus anti-bias comparison, p<.01). However, when tested 6 days later most of this effect had disappeared, particularly in the case of subjects whose initial attitudes were least pro. At this final session, subjects also rated attitude statements on the issue in terms of scales constructed from the pro-bias and anti-bias word lists. In accordance with previous research, the more pro subjects' attitudes, the more they showed greater polarization of judgement on the pro-bias than the anti-bias scales (p<.000l). It is concluded that a person's attitude may be related to the kind of evaluative language he will apply to an issue, and that when a person is induced to use language implying a particular evaluation of an issue, he may change his attitude, at least in the short term, so as to be more congruent with the language he has used.  相似文献

A rating instrument was developed to assess the personality functioning of problem adolescents who have a brief history of official delinquency. Subjects were 186 residents at a short-term diagnostic detention facility. The instrument that emerged from a factor analysis was tested for reliability, validity, and cross-situational generality. Two major orthogonal factors emerged, Apathy-Withdrawal (I) and Anger-Defiance (II). Each factor was found to be congruent with the corresponding dimension on behavior rating instruments that had previously yielded two orthogonal factors and that had been shown to be relevant to a large number of psychological and educational issues. Significant correlations between the factors and a series of global ratings measuring behavior and measures indicative of the frequency and seriousness of official delinquency provided further evidence of construct and discriminant validity as well as evidence of cross-setting consistency of personality functioning.  相似文献

Developmentally, attitudes toward casual alcohol use and toward the abuse of alcohol should be related to the development of value content and value structure. Two studies were conducted that found this to be generally so with upper elementary schoolchildren. A negative attitude toward the abuse of alcohol was definitely related to general measures of the intemalization of those values necessary to be a part of any group as well as the rejection of acts generally considered to be deviant in our culture. Attitudes toward casual use of alcohol were also somewhat related, but not as strongly. However, alcohol attitudes were unrelated to stage of moral development or other measures of thinking processes. Some shifts across age and sex were also noted. Programs oriented toward the prevention of alcohol abuse may need to communicate the value norms of our society and can proceed without impacting attitudes toward casual alcohol use.  相似文献

Three experiments examined memory for metaphorical sentences. No differences between metaphors and nonmetaphorical equivalents (e.g.,The ivy cuddled up to the window vs.The ivy grew up to the window) in the number of correct recalls or recognitions were found. There was, however, a significant trend for recall errors that were meaning-preseving to be less metaphorical than the input sentence. The results supported hypotheses that metaphors and nonmetaphors are equally easy to remember and that the stored memory representation does not distinguish whether its antecedent linguistic input was metaphorical or not.This research was supported by Grant MH 28493-01 from NIMH and by a grant from the Kansas State University Bureau of General Research.Some of the data were reported at the Meeting of the Psychonomic Society, Denver, November 1975.  相似文献

This study compared two levels of syntactic encoding with respect to their effect on aphasics' auditory comprehension. The same informational content was presented either as an embedded sentence or as two contiguous simplé propositions. A similar contrast was utilized to compare sentences containing relational terms of time, comparison, instrumentality, as well as sentences involving conjunction reduction, with parallel messages expressed in expanded, simplified form. A picture-verification paradigm was used. Comprehension was significantly enhanced only in the case of embedded sentences, with a tendency for Broca's aphasics to show the maximum effects.  相似文献
