An experiment and a replication were conducted, testing the hypothesis that the smaller the actual power distance between a subject and a more powerful other, the stronger the tendency to reduce the power distance between them. Power distance was created by placing the subject in a group of three people plus a supervisor. In the condition of large power distance, the three workers had identical functions. Small power distance was induced by placing the subject at an intermediary power level, above the two workers, but below the supervisor. Two other conditions of small power distance were manipulated in order to assess the effects of the timing of power promotion and the perception of the promotion as caused by the subject's task competence. During the course of the experiment, the supervisor left unexpectedly and the subject had the option of taking over the supervisory role or letting one of his co-workers assume it. In the first experiment, subjects who were at a large power distance chose to replace the supervisor significantly less frequently than subjects in the three small power-distance conditions. The small power-distance conditions did not differ from each other. The replication with two small power-distances conditions produced the same results. Both experiments took place in a natural setting. 相似文献

Summary This article reports an experimental investigation testing the hypothesis that recall reports are systematically biased by the recaller's knowledge about who is to receive the recall report, while that bias is absent from a recognition test. Subjects listened to one of two versions of a story recounting John's visit to the doctor. After the story was read, subjects were asked to recall the story either with standard-recall instructions or with instructions to recall for peers, for Martians, or for a contest. In a fifth condition, subjects performed a filler activity, viz., the recall of a personal experience. After the recall test subjects were administered a recognition test. Between the groups no systematic differences in memory performance were observed in the recognition test. Recall for peers appeared to be poorer than recall in the other conditions. Subjects in the recall for a contest condition scored higher than the subjects in the other groups. Not only did groups differ with respect to bias, but there were also systematic differences in the memory or discrimination scores. The findings are discussed within the framework of schema theory. 相似文献

Kruskal, Harshman and Lundy have contrived a special 2 × 2 × 2 array to examine formal properties of degenerate Candecomp/Parafac solutions. It is shown that for this array the Candecomp/Parafac loss has an infimum of 1. In addition, the array will be used to challenge the tradition of fitting Indscal and related models by means of the Candecomp/Parafac process. 相似文献

Kroonenberg and de Leeuw (1980) have developed an alternating least-squares method TUCKALS-3 as a solution for Tucker's three-way principal components model. The present paper offers some additional features of their method. Starting from a reanalysis of Tucker's problem in terms of a rank-constrained regression problem, it is shown that the fitted sum of squares in TUCKALS-3 can be partitioned according to elements of each mode of the three-way data matrix. An upper bound to the total fitted sum of squares is derived. Finally, a special case of TUCKALS-3 is related to the Carroll/Harshman CANDECOMP/PARAFAC model. 相似文献

A paper about cross-cultural and cross-racial loving that emphasizes the need to understand and affirm the plurality in and among women as central to feminist ontology and epistemology. Love is seen not as fusion and erasure of difference but as incompatible with them. Love reveals plurality. Unityndashnot to be confused with solidarityndashis understood as conceptually tied to domination. 相似文献

Centering a matrix row-wise and rescaling it column-wise to a unit sum of squares requires an iterative procedure. It is shown that this procedure converges to a stable solution. This solution need not be centered row-wise if the limiting point of the interations is a matrix of rank one. The results of the present paper bear directly on several types of preprocessing methods in Parafac/Candecomp. 相似文献

3 groups of patients, who suffered on SSPE (without treatment, with isoprinosine therapy, combined treatment with propionibacterium granulosum and isoprinosine) are compared. The results show a favourable effect of the combined treatment in a part of the patients. They are discussed in detail. 相似文献

Phonological priming in spoken word recognition: Task effects 总被引:3,自引:0,他引:3
In two experiments, we examined the role of phonological relatedness between spoken items using both the lexical decision task and the shadowing task. In Experiment 1, words were used as primes and overlaps of zero (control), one, two, or all four or five (repetition) phonemes were compared. Except for the repetition conditions, in which facilitation was found, phonological overlap resulted in interference on word responses. These effects occurred in both tasks but were larger in lexical decision than in shadowing. The effects that were evident in shadowing can be attributed to an attentional mechanism linked to the subjects' expectancies of repetitions. The extra effects obtained in lexical decision can be interpreted by taking into account both activation of the response corresponding to the prime's lexical status and postlexical processes that check for phonological congruency between prime and target. In Experiment 2, some modifications were introduced to prevent the involvement of strategic factors, and pseudowords were used as primes. No effect at all was observed in shadowing, whereas in lexical decision interference effects occurred, which is consistent with the hypothesis that lexical decision may be negatively affected by finding a phonological discrepancy at the same time as the primed response is reactivated. Neither experiment provided evidence for the occurrence of phonological priming in the perceptual processing of words. 相似文献

Two experimental tasks, a speech segmentation and a short-term memory task, were presented to children who began to learn to read following either the “phonic” or the “wholeword” method. The segmentation task required the child to reverse two segments (either two phones or two syllables) in an utterance. The phonic group performed significantly better than the whole-word group in the “phonic reversal” task, but no difference appeared in the “syllable reversal” task. This indicated (1) that most children by the age of 6 years are ready to discover that speech consists of a sequence of phones and (2) that the moment at which they do it is influenced by the way they are taught to read. In the memory task, the children recalled series of visually presented items whose names either rhymed or did not. The difference in performance for the rhyming and nonrhyming series was significant in both groups. It was no greater for the phonic than for the whole-word group and was uncorrelated with the “phonic reversal” task. These results are discussed in connection with the distinction between ways of lexical access and ways of representing verbal information in short-term memory. 相似文献
