A review is presented of a number of recent results concerning fundamental measurement structures with a particular emphasis on generalizations of physical measurement. Relational structures are classified in terms of richness and redundancy of their automorphism groups (i.e., in terms of their symmetries). By means of this classification, the possible types of measurement scales are described, and the possibilities for structures with concatenation operations (either associative or nonassociative and either positive or intensive) and for conjoint structures whose automorphisms factor into component automorphisms are explicitly spelled out. Certain conjoint structures with concatenation operations on components are viewed as generalizations of classical physical measurement and some of their most important algebraic and representational properties are explored. 相似文献

The study described the abilities of a group of 15 moderately impaired aphasics and 15 normals to produce narrative discourse. The experimental tasks included telling stories, summarizing stories, and giving morals to stories. The data were analyzed in terms of sentential grammar, discourse grammar, and subjective ratings of content and clarity of language. The results showed that aphasics produced well-structured discourse. The language of the aphasics' discourse was reduced in both complexity and amount, as compared to that produced by normals. The reduction of language reflected selective reduction of hierarchically organized information. The findings of the study confirm the results of previous research on mildly impaired aphasics, which also showed preservation of discourse structure with selective reduction of information. 相似文献

In order to sensitize therapists in training to the dynamics of helping others change, eight members of a graduate seminar in fluency disorders were asked to develop and maintain a program of personal behavioral change for a period of 4 wk. Their reflections on several features of this experience are discussed under the following categories: (1) Selecting the behavior for modification; (2) developing the contract; (3) motivational factors; (4) personal reflections, and (5) implications for working with stutterers. 相似文献

This experiment tested the hypothesis that there is a relationship between children's comprehension of a syntactic form and the effectiveness of modeling in promoting imitation of that form. Nursery and kindergarten children received pretests for both comprehension and production of reversible passive sentences. Children who produced no passive sentences were classified either as high, intermediate, or low comprehenders on the basis of their comprehension test performance. Within each of these three groups, children were randomly assigned either to a modeling or to a no-modeling control condition. Children in the treatment condition heard a model use passive sentences to describe a series of pictures. As predicted, the imitation post-test scores of these children were significantly related to their comprehension pretest scores. No significant relationship between the post-test scores and the comprehension scores of control subjects was detected. Children exposed to the model in all three comprehension groups received significantly higher post-test scores than did their respective counterparts in the no-modeling condition. These results are discussed in terms of the hypothesis that language learning proceeds from comprehension to imitation to production. 相似文献

Longitudinal data on perceptual-motor, cognitive, and linguistic functioning is reported for two children: one with right hemispherectomy and one with left hemispherectomy. Both levels of functioning and specific profiles of abilities within an area of function are evaluated. The subjects both show effects from damage to the brain: shortened memory span, general perceptual and motor disabilities, and somewhat depressed general intellectual functioning. Areas of comparative strength and weakness in functioning in the two subjects are suggestive of adult patterns of hemispheric specialization, despite the young age of the subjects at the time of brain damage. 相似文献

The purpose of this paper was to examine the basic vocational interest dimensions of women. Two interest inventories designed to measure the six interest dimensions described by Holland (1966) were administered to 126 university freshman women. The correlations between corresponding scales of the two instruments was generally high and application of the spatial configuration analysis resulted in the expected circular ordering found in previous studies. The usefulness of the basic interest dimensions when counseling with women was discussed from a practical and a theoretical point of view. 相似文献

Discrimination learning and reversal problems were given to 128 children aged two and three years in which there were either two, three, six, or nine choice-alternatives per problem. The position of the correct object (either a toy car on the original problem and a ball on the reversal problem or vice versa) was varied randomly among all the possible positions, all other positions being occupied by duplicates of the incorrect object. It was found that two-choice reversal problems were much more difficult than all others. There was also a direct and monotonic relationship between ease of solution and number of choices present during reversal learning. Additional analysis inlicated that position response biases were probably responsible for this effect. 相似文献
