Four experiments examined the relative importance of informational (proportion of correct responses and kinds of errors emitted by a model), social (model competency, sex of model, video vs. audio taped model), and individual difference (sex of subject, grade) variables in observational paired-associate learning. In Experiments I–III, vicarious subjects received cycles of study-model-test trials, while direct subjects were given the same sequences with intervening test or stimulus familiarization trials. In Experiment IV, vicarious subjects received cycles of study-test-model-test trials, while direct subjects received the cycles with a test trial replacing the model trial. No confirmation was provided on test and model trials. Whereas the effects attributable to social and individual difference variables were generally negligible, mere accuracy of the model's responses repeatedly covaried with performance on the last test trial of each cycle. Conditional analyses established that (1) vicarious facilitation is comparable across cycles and localized in items responded to incorrectly on immediately preceding test trials, and (2) observers learn fewer incorrect than correct model responses. Vicarious groups performed at reliably higher levels than direct subjects on model correct but not incorrect items. The results strongly suggest a close correspondence between direct and vicarious verbal learning principles and mechanisms. 相似文献

A pretest/posttest control group design was utilized to examine the effect of social skills training on social interactions with peers, conversational interactions with a novel partner, and ratings of overall social functioning. The results failed to support the hypothesis that social skills training could increase the generalization of overall conversational responding of mentally retarded adults. The results showed that social skills training augmented with self-monitored videotape feedback could not optimize the effects of social skills training alone. The subjects did demonstrate acquisition of the targeted behaviors during training by meeting preestablished criteria for all of the training sessions. However, the subjects failed to generalize those behaviors across settings to in vivosocial situations. 相似文献

Differences between paired paintings in a minimal group context were accentuated when assigned preferences served as the categorization basis. Failure to replicate resource allocation bias in control groups was attributed to the procedural emphasis on paintings, which may have precluded the use of the random categorization as a meaningful comparison dimension. 相似文献

Most clinical studies examining the relation between religion and blood pressure status have focused on church attendance, finding lower pressures among frequent attenders. The present study examines the effect on blood pressure status of a religious meaning variable, importance of religion, both by itself and together with frequency of church attendance. The relation between blood pressure, self-perceived importance of religion, and frequency of church attendance was examined among a rural sample of 407 white men free from hypertension or cardiovascular disease. The data confirmed an interaction between the effects of both religious variables on blood pressure status, with importance of religion having an even greater association with lower pressures than church attendance. Diastolic blood pressures of persons with high church attendance and high religious importance were significantly lower than those in the low attendance, low importance group. These differences persisted after adjusting the analyses for age, socioeconomic status, smoking, and weight-height ratio (Quetelet Index). The difference in mean diastolic pressures based on response to the religious importance variable alone was statistically and clinically significant, particularly among men aged 55 and over (6 mm) and among smokers (5 mm). These findings suggest that both religious attitudes and involvement may interact favorably in their effects on cardiovascular hemodynamics. 相似文献

Speakers' assumptions about the lexical flexibility of idioms 总被引:1,自引:0,他引:1

In three experiments, we examined why some idioms can be lexically altered and still retain their figurative meanings (e.g., John buttoned his lips about Mary can be changed into John fastened his lips about Mary and still mean "John didn't say anything about Mary"), whereas other idioms cannot be lexically altered without losing their figurative meanings (e.g., John kicked the bucket, meaning "John died," loses its idiomatic meaning when changed into John kicked the pail). Our hypothesis was that the lexical flexibility of idioms is determined by speakers' assumptions about the ways in which parts of idioms contribute to their figurative interpretations as a whole. The results of the three experiments indicated that idioms whose individual semantic components contribute to their overall figurative meanings (e.g., go out on a limb) were judged as less disrupted by changes in their lexical items (e.g., go out on a branch) than were nondecomposable idioms (e.g., kick the bucket) when their individual words were altered (e.g., punt the pail). These findings lend support to the idea that both the syntactic productivity and the lexical makeup of idioms are matters of degree, depending on the idioms' compositional properties. This conclusion suggests that idioms do not form a unique class of linguistic items, but share many of the properties of more literal language. 相似文献

The use of intelligence tests in making special education placement decisions for children has come under repeated scrutiny in recent years. Arguments for and against the use of IQs have centered around the issue of test bias. In California a permanent moratorium on the use of intelligence tests in placing minority group children into classes for the educable retarded has been handed down by the court. One defense proposed by advocates of mental testing has been that the tests are biased against socially and economically disadvantaged groups irrespective of race. According to Clarizio (1978), if a test predicts equally well for two groups it can not legitimately be described as biased. The purpose of this investigation was to evaluate the test bias of the Verbal IQ as measured by the Wechsler Intelligence Scale for Children-Revised in relation to predictions of academic achievement in two different socioeconomic status groups. The results indicated that Verbal IQs are not biased with respect to socioeconomic status. Derived regression equations are presented along with an analysis to inspect the statistical power of the original tests. 相似文献

The present study compared the underlying factor structure of the Wechsler Intelligence Scale for Children-Revised for Anglo and Mexican-American children. Subtests of the WISC-R were administered to 109 Anglo and 123 Mexican-American children ranging from 8 to 15 years of age and were analyzed separately for each group. Three factors emerged for each ethnic classification which corresponded closely to those usually reported for the WISC-R. Coefficients of congruence (.84–.89) between factors given the same name for each ethnic group indicated a high degree of similarity in constructs being measured. 相似文献

The present study compared experienced and preservice elementary school teachers' perceptions of the school psychologist. Thirty-two experienced teachers were matched with a like number of second semester juniors in training. A questionnaire asked each respondent to (a) rank a number of school personnel on their importance, (b) assign a number of referral problems to professionals best equipped to handle them, and (c) to rate the school psychologist's functioning on 11 dimensions. The analysis showed that experienced and preservice teachers agreed about the importance of the school psychologist and the appropriateness of referral problems. Analysis of ratings revealed that experienced teachers had a more negative opinion of the school psychologist's functioning when compared to their novice counterparts. 相似文献
