Visual form identification at brief durations was studied under: (a) monocular presentation; (b) dichopic presentation where the same form was presented successively on noncorresponding areas; and (c) dichopic presentation where the same form was presented on corresponding areas simultaneously and successively. Form identification for noncorresponding area dichopic presentation was at the level to be expected from 2independent chances to perceive. Both simultaneous and successive dichopic presentation on corresponding areas gave identification accuracy significantly above the level predicted by the assumption of independence. However, the binocular summation was not complete. When the same amount of energy entering the visual system in a binocular presentation was given in a monocular stimulation, the latter condition gave significantly better identification. 相似文献

Several recent studies by Lehiste have reported that changes in fundamental frequency (F0) can serve as a cue to perceived vowel length and, furthermore, that the perceived lengthening of the vowel can influence perception of the voicing feature of stop consonants in syllable-final position. In Experiment 1, we replicated Lehiste’s basic results for stop consonants in final position. Experiment 2 extended these results to postvocalic fricatives. The final consonant in syllables of intermediate vowel duration was more often perceived as voiced when F0 was falling than when F0 was monotone. In Experiment 3, we examined the F0 contours produced by eight talkers before postvocalic stop consonants and fricatives in natural speech for minimal pairs of words differing in voicing. The amount of change of F0 over the vowel was no greater before voiced than voiceless consonants, suggesting that the earlier perceptual effects cannot be explained by appealing to regularities observed in the production of F0 contours in vowels preceding postvocalic consonants. 相似文献

De re modality is eliminable if there is an effective translation of all wffs into non-de re equivalents. We cannot have logical equivalence unless logic has odd theses, but we can have material equivalence by banning all essences, something the non-de re facts let us do, or by giving everything such humdrum essences as self-identity and banning the more interesting ones. Eliminability cannot be got from weaker assumptions, nor independent ones of even modest generality. The net philosophical import is that, quite apart from the merits of essentialism, de re language has scant utility. 相似文献

Some words have fewer direct associates than others, and, when words varying in set size are studied in a list-learning task, those with smaller sets are more likely to be recalled. This set-size effect is found in cued recall when the words are studied in the absence of related words, but not when studied in the presence of related words. Related words provide context and theoretically inhibit irrelevant associates. The present research determined that set-size effects are found when words are encoded in sentence contexts. In contrast to list-learning experiments, the results of three experiments found such effects even when lexically related words were present in the sentences. Other findings indicated that target-set-size effects were determined by the proximity of related words in the sentence and the nature of the test cue. The results are discussed in relation to a model for explaining set-size effects and to selective findings from the sentence-comprehension literature. 相似文献

The authors examined the association between demographic variables and self-reported multicultural counseling competencies among counselors. A national sample of 220 counselors affiliated with university counseling centers participated in this investigation. Counselors responded to 40 Likert-type statements about multicultural awareness, knowledge, skills, and relationships. Results from a series of multivariate and univariate analyses indicated that Asian American and Hispanic counselors reported more multicultural knowledge than did White counselors, and African American, Asian American, and Hispanic counselors reported more competence in multicultural awareness and relationships than did White counselors. No effects were found for other demographic variables. Implications of these findings are discussed. 相似文献

The present study examined body image satisfaction, dieting tendencies, and sex role traits among a sample of black urban women. While women who felt “too fat” were more likely than other women to engage in both restrictive and nonrestrictive dieting tendencies, in general, the women's body weight and body image did not compel them to utilize extremely restrictive dieting practices. A sizable proportion of the sample reported body image dissatisfaction and weight concerns, yet this did not appear to exert an overwhelmingly negative influence over other aspects of their lives, such as participation in sports, exercise, and sexual activity. Body image satisfaction and sex role traits were related. Dieting tendencies were also related with body image satisfaction. These findings and implications for further research are discussed. 相似文献

A sample of 128 college males and females rated a typical and desirable man or woman on 54 items taken from the Personal Attributes Questionnaire (PAQ). Comparisons of the ratings of a typical man versus a typical woman yielded significant differences (p<.01) on 53 of the 54 items. Thus, stereotypes of the sexes apparently remained strong during the 1970s. Comparisons of the ratings of a desirable man versus desirable woman yielded significant differences on only 12 of the 54 items. These results are interpreted as reflecting a difference between stereotypes (of the typical person) and attitudes (about desirable characteristics). While atttitudes may have changed in the 1970s, stereotypes remained remarkably stable. 相似文献

It is shown that for an inside observer it is impossible to distinguish all states in which a system was at some past time. This holds for classical and quantum systems, but an assumption of determinism is essential in the proof. 相似文献
