Ninety-eight female subjects were presented with a statement made by an attractive or an expert source suggesting that people should sleep less than the usual eight hours. For approximately half of the subjects the source gave a simple statement of opinion, for the other half six separate supporting arguments were also presented. As predicted the manipulation of number of arguments provided had more influence on the effectiveness of the expert than the attractive source. Results were interpreted as supporting the hypothesis that quite different dynamics underly the persuasive power of attractive and expert individuals. 相似文献

Word and category recognition was investigated in the context of other stimuli, where the semantic distance relationships among the stimuli were derived from multidimensional scaling. On each trial, three horizontal strings of letters were presented. In the word condition, a positive response was required when the three strings formed three words; in the category condition, a positive response was required when the three strings formed words belonging to the same category. The results indicated that: (a) category decisions take about 150-200 msec longer than do word decisions, (b) word decisions are facilitated by a common categorical membership but semantic distances within the category are relatively unimportant, and (c)within-category semantic distances systematically altered response time for the category condition. It was hypothesized that semantic distance relationships may be sensitized for categorical decisions, but that only large semantic distances function effectively for word decisions. 相似文献

Voice recognition was assessed by a matching to sample procedure in 30 right-handed adults with normal hearing. The subject was required to indicate which of three voices speaking a nonsense syllable matched the speaker of a sample vowel. Subjects were able to recognize voices with reasonable accuracy, but there were no significant differences as a function of ears or practice, and performance was not markedly affected by knowledge of results or mode of response. There was a significant difference as a function of the temporal position of the matching voice, with recognition being most accurate when the matching voice was first and least accurate when it was third. Further research is necessary to determine whether voice recognition should be classified as the type of verbal ability associated with the cerebral hemisphere dominant for speech, or whether it is the type of nonverbal auditory ability associated with the nonspeech hemisphere.This research was supported in part by grant MA-1652 from the Medical Research Council of Canada. 相似文献

The optical distortion caused by wearing a facemask in water magnifies the angular size of objects and reduces their optical distance. However, objects generallyappear to be further than their optical distance, with the result that points in the left part of the visual field are apparently displaced to the left, and those on the right to the right. Experiments on hand-eye coordination under water showed that adaptation to one aspect of the distortion produced some counteradaptation to complementary aspects: adaptation to distance produced increased lateral distortion, and adaptation to one side of the lateral distortion produced increased distortion on the opposite side. Nevertheless, “trading” was incomplete, and some overall adaptation of the visual metric occurred. 相似文献

We present an algebraic-style of semantics, which we call a content semantics, for quantified relevant logics based on the weak system BBQ. We show soundness and completeness for all quantificational logics extending BBQ and also treat reduced modelling for all systems containing BB
d
Q. The key idea of content semantics is that true entailments AB are represented under interpretation I as content containments, i.e. I(A)I(B) (or, the content of A contains that of B). This is opposed to the truth-functional way which represents true entailments as truth-preservations over all set-ups (or worlds), i.e. (VaK) (if I(A, a) = T then I(B, a)= T).This paper was presented to the Australasian Association for Logic Conference, held at the University of Auckland from 9–12th July, 1986. I wish to thank those present for some helpful comments. I also wish to thank Kit Fine for some useful discussion on some topics of this paper. 相似文献

Previous research is consistent with the proposition that people use implicit theories of personal stability or change in remembering the attributes they possessed in the past. However, there has been little systematic investigation of the relation between these implicit theories and memory biases. In this study, the relation between women's theories of menstrual distress and their recollections of physical and affective symptoms was examined. Ss completed daily questionnaires in which they evaluated themselves on several physical and affective symptoms. Later, some Ss were asked to recall the ratings they had made on a day when they were menstruating; others recalled a day when they were not menstruating. At the time of recall, all Ss were in the intermenstrual phase. Finally, Ss completed a measure designed to assess their theories of how they are typically affected by menstruation. The recollections of Ss who recalled the menstrual state were biased so as to be consistent with their theories of menstrual distress: The more a woman believed in the phenomenon of menstrual distress, the more she exaggerated, in recall, the negativity of her symptoms during her last period. The recollections of women asked to recall the intermenstrual state were unrelated to their theories of menstruation. Furthermore, consistent with previous research, the daily questionnaire ratings revealed that physical symptoms varied with menstrual cycle phase, whereas affective symptoms did not. Finally, comparisons between subjects' theories and daily ratings revealed that, on average, women exaggerate the degree to which they experience changes during menstruation. 相似文献

In part I, we presented an algebraic-style of semantics, which we called “content semantics,” for quantified relevant logics
based on the weak systemBBQ. We showed soundness and completeness with respect to theunreduced semantics ofBBQ. In part II, we proceed to show soundness and completeness for extensions ofBBQ with respect to this type of semantics. We introducereduced semantics which requires additional postulates for primeness and saturation. We then conclude by showing soundness and completeness

Two issues were investigated concerning the retrieval of recently acquired relevant information for solving riddle problems. First, although earlier research indicated that problem solvers often fail to retrieve relevant information unless they are explicitly informed of its relevance, Bowden (1985) suggested that uninformed subjects would benefit greatly from additional problem-solving time. In two experiments, we found that uninformed subjects solved more problems than did subjects who did not receive the information, but a simple model attributed this difference to these uninformed subjects "catching on" to the information's relevance after solving some problems. Second, the retrieval characteristics were examined by varying the proportion of problems for which clues were given. Informed subjects given clues for only half of the problems benefited (though perhaps not fully) from being informed, without incurring any cost from being misdirected on the unclued problems. The discussion focuses on some ways in which accessing relevant information may affect problem solving. 相似文献

This article considers procedures for combining individual probability distributions that belong to some “family” into a “group” probability distribution that belongs to the same family. The procedures considered are Vincentizing, in which quantiles are averaged across distributions; generalized Vincentizing, in which the quantiles are transformed before averaging; and pooling based on the distribution function or the probability density function. Some of these results are applied to models of reaction time in psychological experiments. 相似文献
