This study explored the extent to which rapid temporal processing and duration contribute to the right-ear advantage (REA) and presumably left-hemisphere processing for stop consonants and the lack of clear-cut laterality effects for vowels. Three sets of synthetic stimuli were constructed: consonant vowel stimuli [ba da ga bi di gi bu du gu] of 300 msec duration (full stimuli) and two shortened stimuli consisting either of a noise burst and 40-msec transitions (40-msec stimuli), or a noise burst and 20-msec transitions (20-msec stimuli). Stimuli were presented dichotically for consonant, vowel, and syllable identification. Results indicated a significant REA for consonants in the full and 40-msec conditions and a non-significant REA in the 20-msec condition. Nevertheless, the magnitude of laterality did not change across the three conditions. These results suggest that although transition information including duration contributes to lateralization for stop consonants, it is the presence of abrupt onsets which crucially determines lateralized processing. For vowels, there was a significant REA only in the full stimulus condition, and a significant decrement in the magnitude of the laterality effect in the two shortened stimulus conditions. These results suggest that for vowel perception, it is the nature of the acoustic cue used for phonetic identification and not duration that seems to be the critical determinant of lateralization effects. 相似文献

Two experiments examined alternative explanations for the Scheier and Carver(1977) results linking self-focused attention to increased responsivity to emotional stimuli. In both studies autonomic, expressive, and self-report measures of emotional arousal failed to confirm the earlier findings. An individual difference measure reported by others to parallel the effects of situationally manipulated self-attention also failed to confirm the previously reported findings. Though in direct contradiction to Scheier and Carver's results, the results are consistent with a facial feedback hypothesis and with previous findings on the effects of expressive inhibition on self-reports of emotional arousal.This research was supported in part by NSF grant 77-08926 to the first author and by NIMH grant MH 29446 to the third author, as well as by funds from the Lincoln Filene Endowment to Dartmouth College. 相似文献

An 8-month-old infant with a developmental quotient of months was given response-contingent stimulation using a pressure-sensitive pillow which turned an overhead mobile. The subject learned to control the mobile by kicking the pillow, and concurrently began smiling at both the mobile and her mother for the first time. After mastering three contingencies on arm, head, and leg movement, she displayed what appeared to be a Piagetian coordinated secondary circular reaction, in which one response provided 4 seconds of access to another contingency. Although the subject remains severely retarded, the results suggest that some forms of developmental delay may be treated at least in part as a failure to develop contingency awareness. 相似文献

What career decision-making procedures enable people to make decisions that yield consequences congruent with their own values? The 40 “best” (most congruent) and 40 “worst” decision makers on the Career Decision Simulation were compared in a sample of 148 community college students. No significant differences appeared in the amount of double checking, number of occupations and information sources checked, amount of information collected, decision time required, and the proportion of information sought about high values. The “best” decision makers, however, were significantly more persistent in immediately seeking more information about an occupation that seemed to match one of their most important personal work values. Following a values-guided search appears more effective than simply searching exhaustively. 相似文献

There is a lack of consistency in findings regarding subject (S) characteristics and the effects of smoking-control programmes. Research workers appear to assume that abstinence and reduction in smoking rate are merely different points in the same continuum, and therefore seek to correlate S variables with percentage reductions in smoking rate. It is argued that abstinence and reduced smoking are more appropriately viewed as potentially discrete outcomes. Conceptualizing outcome in this manner, a discriminant function analysis was employed to determine whether it is possible to differentiate between Ss who do, or do not, abstain following participation in a treatment programme involving rapid-smoking. It was found that it is possible to discriminate between the two groups of Ss. Advantages deriving from this approach to the investigation of S characteristics and treatment outcome are discussed. 相似文献

To minimize the verbal content of the attitude measurement situation with Papua New Guinea students, a set of pictorial items was selected for use in the place of verbal items. Initially, 150 pictures related to concepts in the Wilson-Patterson Attitude Inventory (WPAI) were described by a group of 50 students. Seventy of these items, those which were described in a consistent way, were presented to 227 students along with a Papua New Guinea version of the WPAI. A final set of 25 pictures was selected on the basis of their discriminative power, internal consistency, and their content validity. Reliability and validity measures and the rotated factor structure of the 25 item pictorial scale were consistent with the WPAI. 相似文献

Many questions are currently being raised, by women especially, regarding the religious, social, and psychological effects of the emphasis on God as father in Western religion. Viewed in the light of key insights from developmental psychoanalysis, patriarchal monotheism does indeed seem to confront us with a dilemma. However, a resolution of this dilemma does not appear to lie in a move toward androgyny or matriarchy. Evaluated from the point of view of its overall capacity to mediate a meaningful, unified, personal religious reality to both sexes, monotheistic father religion is still the preferable ultimate symbolic configuration. 相似文献

Two strategies used to test prerequisite relationships among intellectual skills were employed to examine the sequence of three types of subtraction tasks. A psychometric validation strategy yielded results similar to an instructional validation strategy. This finding provides support for the use of the more efficient psychometric approach for validating large numbers of learning hierarchies in relatively short periods of time. 相似文献

Abstract. This essay attempts to explore the senses in which religious meanings may be understood to be grounded ontologically and in which they may be validly accepted as true. It begins by outlining Wolfhart Pannenberg's proposal for conceiving the scientific status of theology and his formulation of the question of theological truth. Then certain epistemological presuppositions are challenged in light of Michael Polanyi's theory of knowledge. Finally a revised understanding is proposed in Polanyian terms. Here in their primordial sense religious meanings are based in the act of breaking out toward the ground of our tacit foreknowledge. In their primary sense religious symbolizations are accepted as human creations and judged to be valid insofar as they integrate meaningfully all the disparate elements of our experience. 相似文献

Some authors have described Niels Rohr as “never being open to anything transcendental.” Wolfgang Pauli, on the other hand, spent many years trying to persuade Bohr to admit to a kind of’ mysticism. This study offers support to Pauli's claims. First, a distinction between what is vague on the one hand, and what is necessarily circular on the other, clarifies the work of Bohr. This discussion leads to comments on Bohr's attitude towards the mutuality of spirit and matter and of reason and mysticism. Finally, some reflections are made about the relevance of Bohr's covert transcendental philosophy for theological endeavors. 相似文献
