Eighteen children, randomly assigned to one of six conditions, were trained in the use of two-word subject-verb (e.g. “mommy go”) utterances. The groups differed in (1) the number of different semantic relations theoretically underlying the subject-verb utterances on which the children were trained, and (2) the extent to which these semantic relations were associated with nonlinguistic events. The results indicated that the children acquired the subject-verb utterance forms more readily when they were also exposed to the events to which the utterances actually referred. Provided that the subject-verb utterances were related to ongoing events, the number of relations “underlying” these utterances did not appear critical. These results suggest that the child's acquisition of novel and grammatical utterances describing nonlinguistic stimuli highly similar to those in his natural environment are amenable to experimental control. 相似文献

The purpose of this study was to test the currently held theory of homogeneous matching of a student to a college and its effect on college choice satisfaction. Measures of scholastic potential, personality, and interest, and subcultural orientation on 7,257 freshmen enrolled in 28 colleges were related to their expressions of satisfaction with their choice of college. The contention that students most similar or dissimilar to students at their chosen school would be most satisfied or dissatisfied was not supported. The relationship between satisfaction and matching is minimal and quite complex and casts serious doubt on this form of placing students in college. 相似文献

This article presents the results of an investigation of the relationship of biographical information to the performance of counselors in state rehabilitation (DVR) agencies. The specific purposes of this study were to examine (1) what biographical data items differentiate more successful DVR counselors from less successful DVR counselors, and (2) if factors across biographical items could be found that relate to more successful performance. A series of statistical steps were involved in the analyses including chi-square, reciprocal average weighting technique, factor analysis, and a multiple regression model. No significant relationship to the criterion of supervisor ratings on overall effectiveness was found using either of two weighting procedures, nor were the responses to items composing the factors associated with the criterion variable. Some implications and limitations of the study were discussed. 相似文献

The hardware and software for a computer-controlled training and testing system for primates are described. The computer (DDP-116 in the Computer-Controlled Psychology Laboratory at Carnegie-Mellon University) controls all stimulus presentation, reinforcement, and records data in a form ready for analysis on a larger computer. 相似文献

Ss were presented pairs of items on study cycles; on test cycles Ss were presented the stimulus items and required either to recall the correct response or to indicate the correct response from three alternatives. It was demonstrated that Ss who chose the correct responses from the alternatives tended to select from both stimulus and response compounds so that the association was between stimulus and response components. The amount of selection from the response compounds was comparable to that from the stimulus compounds. 相似文献

The specification of sample size is an important aspect of the planning of every experiment. When the investigator intends to use the techniques of analysis of variance in the study of treatments effects, he should, in specifying sample size, take into consideration the power of theF tests which will be made. The charts presented in this paper make possible a simple and direct estimate of the sample size required forF tests of specified power. 相似文献
