The development of effective training programs for persons with profound mental retardation remains one of the greatest challenges for behavior analysts working in the field of developmental disabilities. One significant advancement for this population has been the reinforcer assessment procedure developed by Pace, Ivancic, Edwards, Iwata, and Page (1985), which involves repeatedly presenting a variety of stimuli to the client and then measuring approach behaviors to differentiate preferred from nonpreferred stimuli. One potential limitation of this procedure is that some clients consistently approach most or all of the stimuli on each presentation, making it difficult to differentiate among these stimuli. In this study, we used a concurrent operants paradigm to compare the Pace et al. (1985) procedure with a modified procedure wherein clients were presented with two stimuli simultaneously and were given access only to the first stimulus approached. The results revealed that this forced-choice stimulus preference assessment resulted in greater differentiation among stimuli and better predicted which stimuli would result in higher levels of responding when presented contingently in a concurrent operants paradigm. 相似文献

A study was conducted to examine the accuracy of prediction of facial expressiveness from knowledge of the norms of expressiveness in same-sex and mixed-sex social interactions. Men and women subjects were videotaped while they viewed emotionally loaded stimulus slides and rated their responses to them. The edited videotapes were shown to judges who attempted to identify the emotion reported by each viewer for each slide. A separate group of subjects was asked to rate how acceptable or appropriate it is for a man or a woman to express each target emotion under the conditions of the slide-viewing study. The accuracy of emotion identification data correlated highly with acceptability ratings across emotions and sex pairings, although examined more closely, the data show this predictability only for same-sex pairings. Alternative explanations for these results in terms of display rules and the social demands of interactions are discussed.The authors wish to thank Alan Fridlund for helpful comments on a previous version of this paper. 相似文献

The effects of perceptual adjustments to voice information on the perception of isolated spoken words were examined. In two experiments, spoken target words were preceded or followed within a trial by a neutral word spoken in the same voice or in a different voice as the target. Over-all, words were reproduced more accurately on trials on which the voice of the neutral word matched the voice of the spoken target word, suggesting that perceptual adjustments to voice interfere with word processing. This result, however, was mediated by selective attention to voice. The results provide further evidence of a close processing relationship between perceptual adjustments to voice and spoken word recognition. 相似文献

Pre-recorded, or “canned” laughter is often used to encourage audience laughter. Previous research suggests that hearing others laugh can influence an audience, although several variables moderate its effects. We examined an unexplored moderator, hypothesizing that canned laughter would influence listeners only if they believed the laughter came from fellow in-group members. We manipulated the presence or absence of canned laughter in a potentially humorous recording and participants’ beliefs about the in-group or out-group composition of the laughing audience. The results confirmed our hypothesis: participants laughed and smiled more, laughed longer, and rated humorous material more favorably when they heard in-group laughter rather than out-group laughter or no laughter at all. 相似文献

Two hundred forty-one undergraduates described their experiences with unrequited love, both as pursuers (actors) and love interests (targets). As expected, targets and actors perspectives differed. As targets, participants reported being on the receiving end of more unwanted courtship tactics, violent and nonviolent, than they reported using as pursuers. Further, participants in the actor role—particularly men—tended to overreport receiving signals that their love interest was reciprocating, and to underreport receiving rejections. Meanwhile, targets—particularly women—claimed numerous attempts to reject, including explicitly stating “I am definitely not interested in you,” and indicated minimal positive reactions to the unwanted pursuit. Implications of these differences, and others, in perspectives for understanding difficulties in differentiating persistence from stalking are discussed. 相似文献
