Four listeners (experimental group) received one trial a session for 60 sessions on a monaural localization task in which six loudspeakers, positioned 15 deg apart, were placed on the side of the functioning ear. Four additional listeners (control group) received 60 massed trials first and then one trial a session for 60 sessions. The stimulus consisted of a single train of five high-frequency pulses. An ANOVA conducted on the 60 trials distributed over sessions showed that the experimental group’s performance was significantly inferior to that of the control group. Members of the former continued to displace sounds toward the open ear throughout the entire test. Those of the control group exhibited this tendency, but to a much lesser extent. The experience of locating 60 massed trials clearly had a robust effect on subsequent performance. We contend that, by virtue of presenting only one trial a session, the magnitude of the massed-trial effect was little attenuated by our tests to measure it. We interpret our substantive finding to mean that during the 60 massed trials, the control group formed a perceptual representation of the auditory space which served it well when placed on the one-trial-a-session regimen. Those in the experimental group were unable to develop an adequate representation of the auditory space, presumably because their monaural localization experience was restricted to only one trial a session. 相似文献

The present investigation examined the effects of varying the standard assessment conditions on performance of social skills among normal and psychiatric inpatient children. Sixty children (30 normals, 30 patients), ages 6–12, completed behavioral and self-report measures of social skills on two separate occasions. During the second assessment, half of the children received feedback and incentives for performance; the other half did not. The testing conditions consistently altered social skill performance. Children who received the incentives during assessment showed significantly higher levels of social skills, as reflected in concrete behavior (e.g. eye contact, facial expressions), and molar responses (e.g. giving compliments, responding to provocation). The results suggest that social skills performance varies considerably as a function of the assessment conditions. Training programs should not assume that persons do not have the responses in their repertoires merely because of low pretest performance unless more extensive efforts are made to evoke appropriate responses. 相似文献

Typically in large residential facilities for retarded persons, meals are served in an institutional style that does not appear to encourage appropriate peer interactions. An ecological program alternative is serving meals in a family style. The present study was designed to examine both the feasibility of serving family style meals and the effects of family style meal service on mealtime language. Five retarded young adult male residents, who had some conversational skills and appropriate table manners, participated in this study. The experimental design involved a multiple baseline analysis across meals (dinner, lunch, and breakfast). Observers coded the youths' mealtime verbalizations according to the type, content, and direction of the verbalizations and they recorded the length of the meals. The analysis of the verbalization data indicated that during family style meals the participants spoke substantially more often than during institutional style meals. Increases in peer-directed conversation about the meals primarily accounted for the verbalization changes. Family style serving also resulted in the youths spending more time with their meals. In addition, social validation measures suggested that the family style procedures were preferred by the consumers (participants, staff, and concerned community members). 相似文献

This paper reports two cued recall experiments in which the degree of preexperimental associative strength between rhyming cues and their respective targets is manipulated whilst holding the extent of informational overlap between them constant. Both experiments show that strong rhyming cues are more efficient than weak rhyming cues in eliciting target retrieval in both a short-term and a long-term memory situation. The results are interpreted as consistent with the generationrecognition theory of retrieval and inconsistent with predictions made by the encoding specificity principle. It is therefore suggested that caution must be applied when extending the encoding specificity principle to experimental situations other than that from which it is derived. Implications for the distinction between scanning and reconstructive modes of retrieval are also briefly considered. 相似文献

The present study examined differences in pelvic vasocongestion as a function of negative attitudes toward masturbation. Pelvic vasocongestion was measured thermographically, which is a noninvasive means of detecting and photographing individual heat patterns to indicate physiological condition and functional changes within. The results indicated that women, with positive attitudes toward masturbation, who read an erotic story, experienced the greatest increase in pelvic vasocongestion. This and other findings were discussed in terms of masturbation acting to facilitate the patterning of sexual arousal and orgasmic functioning, especially in regard to creating the capacity for pelvic engorgement. 相似文献

Using a sample of Toronto women, we reexamine the relationship between employment and fertility with the aim of clarifying whether employment status is negatively related to the birth rate only among certain categories of women as defined by sex roles. Especially noteworthy is the finding that employed wives who rate their performance as a spouse and mother as better than most have a birth rate which is as high as that for women who are not in the labor force.The authors are indebted to David Johnson, Susan Welch, and Lynn White of the University of Nebraska, and Gordon Irving of Carleton University for their comments on an earlier version of this article. The views expressed here are the authors' and not those of the Ministry of State for Urban Affairs, Government of Canada, which provided funds to conduct the study of urban crowding from which the data reported here were drawn. 相似文献

A recurrent problem in interpreting research showing differential reactions to the sexes is that such results may reflect real behavior differences among those observed or differential expectations of those observing. This study used a methodology which allowed these two competing explanations to be tested by assessing whether subjects' ratings of taped interactants whose gender was ambiguous would be determined mainly by what gender the subjects thought the interactants were or by the interactants' behavior. The results showed that the causes of the sex differences in assessments differed depending on what type of assessment was being made. Specifically, behavior differences and not observers' expectations about such differences largely determined observers' ratings of specific attributes of the interactants, but observers' expectations and not behavior differences determined observers' general ratings of masculinity/femininity. 相似文献
