Synthetic data are used to examine how well axiomatic and numerical conjoint measurement methods, individually and comparatively, recover simple polynomial generators in three dimensions. The study illustrates extensions of numerical conjoint measurement (NCM) to identify and model distributive and dual-distributive, in addition to the usual additive, data structures. It was found that while minimum STRESS was the criterion of fit, another statistic, predictive capability, provided a better diagnosis of the known generating model. That NCM methods were able to better identify generating models conflicts with Krantz and Tversky's assertion that, in general, the direct axiom tests provide a more powerful diagnostic test between alternative composition rules than does evaluation of numerical correspondence. For all methods, dual-distributive models are most difficult to recover, while consistent with past studies, the additive model is the most robust of the fitted models.Douglas Emery is now at the Krannert Graduate School of Management, Purdue University, West Lafayette, IN, on leave from the University of Calgary. 相似文献

A model is presented to account for the data from incremental cuing experiments that have been carried out to identify the representation of propositions in memory. In such experiments subjects first learn a list of sentences and are afterward cued for recall with words from the learned sentences. The model proposed distinguishes between a memory structure and stimulus and response processes. The all-or-none tendency in the data is captured by a Gestalt-like memory code. The model is compared with the stochastic theory of Anderson and Bower and the fragmentation hypothesis of Jones. 相似文献

A probe-latency task was used to assess accessibility to the words from the first and second clauses of four types of sentences. The sentences contained either independent clauses or main and subordinate clauses. The subjects were 3-, 4-, and 5-year-old children, and adults. On sentences with no main-subordinate distinction, word recognition latencies were shorter for second clauses for all groups except 4-year-olds. On sentences with main and subordinate clauses systematically varied over position in the sentence, however, latencies were most often shorter for subordinate clauses, even when they occurred at the beginning of the sentence. The results indicate that a clause is not simply represented in abstract form rather than verbatim form once the complete clause has been heard, but instead the structural role of the clause, as well as other factors, influences accessibility to verbatim form. It is proposed that listeners frequently interpret an asserted main clause more readily than a subordinate clause. This comprehension strategy appears in different forms at different stages of development.This research was supported in part by NIMH Fellowship No. 1 FO2MH 57352-01 and in part by a Montclair State College Faculty Research Grant to the first author. 相似文献

This study utilized the Synthetic Sentence Identification/Ipsilateral and Contralateral Competing Message subtests and the State-Trait Anxiety Inventory to examine auditory processing deficits, anxiety levels, and the interaction of these two components in 15 adult stutterers and 15 nonstutterers. Results support brainstem auditory processing deficits in stutterers and equalization of cortical functioning between groups. Group differences were not found in anxiety levels. Nonsignificant correlations between anxiety levels and auditory processing were revealed. 相似文献

According to logical learning theory, a reinforcement involves the extension of meanings predicated by subjects who are asked to perform in a learning task. Based on this theoretical position, it is predicted that subjects who are administered a reinforcement following their successful anticipation of the second member of a paired-associates unit will acquire their liked trigrams more readily than their disliked trigrams (mixed lists). Conversely, it is predicted that subjects who are reinforced following their incorrect anticipations of the second paired-associates member will acquire their disliked trigrams more readily than their liked. College students (divided equally by sex) were exposed to one of three reinforcement conditions: positive reinforcement, negative reinforcement, and no reinforcement (control). Trigrams reliably rated for likability by each subject were used as learnable materials. Although the control condition did not perform as expected, the remaining experimental conditions support the hypotheses. 相似文献

Influence of six types of visual structure on complexity judgments in children and adults 总被引:1,自引:0,他引:1

Individuals at five grade levels (kindergarten, Grade 2, Grade 4, Grade 6, and college) made pair-comparison judgments of visual complexity. The influence of the presence or absence of six types of visual structure (double symmetry, vertical symmetry, horizontal symmetry, diagonal symmetry, checkerboard organization, and rotational organization) and of amount of contour were examined. Two general developmental trends were revealed: First, the age at which visual structure initially affected complexity judgments varied with the type of structure, independent of amount of contour, within the range of contour values used. Second, there was a uniform increase in the effect of structure on complexity judgments between the fourth and sixth grades. These results are discussed in relation to possible mechanisms of visual pattern encoding and complexity judgment. 相似文献

An account of the work done before, during and after the Workshop meetings is given, with emphasis on the method of working with clinical material through a psychoanalytical framework. Some of the leaders' concerns about using an experiential approach in teaching/learning groups are discussed. 相似文献
