Role plays or social simulations are presently one of the most common methods for assessing social skills. Although social simulation techniques have become quite popular, little is known about the psychometric adequacy of many of the role-play instruments which have been developed. This investigation was an attempt to determine certain properties of one particular social skills assessment instrument: the Simulated Social Interaction Test. The effects of various confederate prompt delivery styles on the judged social competency level of subjects in the Simulated Social Interaction Test were examined. Two confederates, one male and one female, were trained to portray three confederate prompt delivery styles: (a) unreceptive, (b) neutral, and (c) receptive. In order to determine if judges would compensate for the different confederate prompt delivery styles, two sets of trained judges rated the levels of skill and anxiety generated by the 30 subjects tested. One set of judges was screened from the confererate delivery while observing the simulation; the other set of judges followed the more common rating procedure (i.e., they were not screened from the confederates' deliveries). Data analysis examined variation in subject performance under each condition and according to each set of judges for both overall social skills and anxiety ratings. Confederate prompt delivery style was found to affect subjects' rated performance. There was also suggestive evidence that judges were sometimes able to compensate for different confederate delivery styles. The practical and theoretical implications of the results are discussed.This study was funded in part by a research grant from the Veterans Administration. 相似文献

This series of experiments examined zero-delay matching-to-sample performance in pigeons with element and compound sample stimuli. In Experiment 1, compound sample stimuli were consistently followed by compound comparison stimuli and matching accuracy during testing was equivalent to element sample-element comparison trials on the color dimension. In Experiment 2, element comparisons suddenly introduced following compound samples produced a decrement on the line dimension only. Subsequent testing at various sample durations revealed higher matching accuracy following element samples than following compound samples on both the color and line-tilt dimensions. Experiment 3 replicated the results of Experiments 1 and 2 and also demonstrated that the superiority of element over compound matching performance remains constant over the sample durations tested. In Experiment 4 testing at sample durations up to 30 sec produced an overall decrement in matching performance, but again the element vs compound matching difference remained constant. The stimulus-generalization decrement hypothesis provided a better explanation of these results than either the information-overload hypothesis or the rule hypothesis. 相似文献

Recent Pavlovian conditioning experiments presented all possible CS-US combinations of red-light and tone CSs and food and shock USs to separate groups of pigeons. Pigeons receiving shock USs demonstrated conditioned head raising followed by prancing to both CSs, but CRs were acquired more rapidly to tone than to red light. Although pigeons receiving food USs rapidly acquired a conditioned response of pecking to the red-light CS, there was no evidence of conditioned responding in groups receiving tone-food pairings. This outcome left open the possibility that Pavlovian pairings of tone and food may have resulted in association formation that was not revealed in performance. The present series of experiments attempted to reveal that association, using an indirect method of assessment, conditioned reinforcement. Experiment 1 demonstrated that both red light and tone paired with food became positive conditioned reinforcers, suggesting that an association between tone and food was formed in the same number of Pavlovian conditioning trials that previously failed to yield any direct evidence of conditioning. Experiment 2, which presented fewer conditioning trials, revealed that the tone-food association was formed less rapidly than the red light-food association. Experiment 3 demonstrated that the observed outcomes were not attributable to unconditioned, rather than conditioned, reinforcing effects of the Css. 相似文献

The hypothesis that latent inhibition could be reduced by extinguishing the experimental context, that is, exposing the rats to the context between exposure to the conditional stimulus (CS) and conditioning, was tested. All experiments used the conditioned emotional response procedure. In Experiment 1, extinction was not effective when the animals were exposed to the clicker 40 times off the baseline of responding for food and when the clicker CS was partially reinforced with shocks during the test phase. In Experiments 2 and 3, latent inhibition could be reduced by extinction if the animals were exposed to the CS 24 or 16 times on-baseline, and if continuous reinforcement was used during the test. In Experiments 4, 5, and 6, we attempted to determine which variable was responsible for the discrepant results. In Experiment 4, extinction was effective with 20 or 40 on-baseline exposures to the CS, using continuous reinforcement during the test. In Experiment 5, extinction was not effective with exposure on- or off-baseline, using 24 exposures and partial reinforcement. Finally, in Experiment 6, extinction reduced latent inhibition using continuous, but not partial, reinforcement with 40 exposures off-baseline. From these results, we concluded that Wagner's model of habituation was not sufficient to account for latent inhibition and that a hybrid model, using both associative and cognitive representational processes, was necessary. 相似文献

Automatic access of the meanings of ambiguous words in context: Some limitations of knowledge-based processing 总被引:1,自引:0,他引:1

Five experiments are described on the processing of ambiguous words in sentences. Two classes of ambiguous words (noun-noun and noun-verb) and two types of context (priming and nonpriming) were investigated using a variable stimulus onset asynchrony (SOA) priming paradigm. Noun-noun ambiguities have two semantically unrelated readings that are nouns (e.g., PEN, ORGAN); noun-verb ambiguities have both noun and verb readings that are unrelated (e.g., TIRE, WATCH). Priming contexts contain a word highly semantically or associatively related to one meaning of the ambiguous word; nonpriming contexts favor one meaning of the word through other types of information (e.g., syntactic or pragmatic). In nonpriming contexts, subjects consistently access multiple meanings of words and select one reading within 200 msec. Lexical priming differentially affects the processing of subsequent noun-noun and noun-verb ambiguities, yielding selective access of meaning only in the former case. The results suggest that meaning access is an automatic process which is unaffected by knowledge-based (“top-down”) processing. Whether selective or multiple access of meaning is observed largely depends on the structure of the ambiguous word, not the nature of the context. 相似文献

Two patients presenting a pattern of recovery yet unreported in the literature were observed, one in Paris, the other in Montreal. Both patients alternately suffered severe word-finding difficulties in one language while remaining relatively fluent in the other. They retained good comprehension in both of their languages at all times. They were able to translate correctly and without hesitation from the language they could speak well at the time into the language unavailable for spontaneous use, but were unable to translate from their temporarily poor language (which they understood well) into the language which they could speak quite well at the time. 相似文献

A visual analogue of an auditory dichotic listening experiment was carried out using what may be termed dichotomous visual presentation of lists of either three or four stimuli. Each stimulus consisted of several identical letters which were arranged so as to form the outline of a second, large letter. Subjects attended to either the small or large letters, and recalled either the attended or unattended letters first. It was found that the results for the three-stimulus and four-stimulus lists differed substantially; they were interpreted as consistent with the model of short-term memory proposed by Broadbent (1975). 相似文献

The purpose of this paper is to make the reader aware of the various theoretical categories into which people who have been productive in the area of stuttering can be “slotted.” Readers are encouraged to read the characteristics, as I conceive of them, of each group of people and then see where their favorite “authorities” (which in many cases will undoubtedly include themselves) fit. 相似文献

The comparative effectiveness of two time-limited modes of training observers to code activity on the Staff-Resident Interaction Chronograph (SRIC) in residential treatment programs for mentally disabled adults was evaluated. The susceptibility of training procedures for consensual observer drift was also examined, as was the predictability of SRIC mastery from trainee characteristics. Two equated groups of undergraduate student trainees (N=15 each) participated in full-time training for 27 days, followed by two weeks of criterion testing in vivo and on videotapes. One group received training by experience personnel using procedures known to be effective (original method). The other group received training via a previously untested set of written and videotaped procedures that do not rely on experienced personnel (package method). Multivariate and univariate analyses of variance found both methods to be equally effective in the degree of mastery achieved by trainees, without evidence of observer drift. No meaningful predictions of coding mastery were found, but conceptual mastery was predictable from individual characteristics. Differences were obtained for both groups between in vivo versus videotaped criterion tests. The results document procedures that are both efficient and resistant to invalidity for complex observational methodology as well as feasible for standardizing assessment of staff functioning across residential settings.This article is based on a thesis submitted to the Graduate College of the University of Illinois at Urbana-Champaign in partial fulfillment of the requirements for the Ph.D. degree in psychology by the first author under direction of the second author.
