In this study, we investigated bases for encoding linguistic stimuli in short-term memory. Past research has provided evidence for both phonological (sound-based) and cherological (sign-based) encoding, the former typically found with hearing subjects and the latter with deaf users of sign language. In the present experiment, encoding capabilities were delineated from encoding preferences, using 58 subjects comprising six groups differing in hearing ability and linguistic experience. Phonologically related, cherologically related, and control lists were presented orally, manually, or through both modalities simultaneously. Recall performance indicated that individuals encode flexibly, the code actually used being biased by incoming stimulus characteristics. Subjects with both sign and speech experience recalled simultaneous presentations better than ones presented orally or manually alone, which reveals the occurrence of enhanced encoding as a function of linguistic experience. Total linguistic experience appeared to determine recall accuracy following different types of encoding, rather than determining the encoding basis used. 相似文献

Two groups of singers (n = 12,13) and a group of nonsingers (n = 12) each produced the national anthem by (1) speaking and (2) singing the words and by (3) humming the melody. Regional cerebral blood flow (rCBF) was measured at rest and during each phonation task from seven areas in each hemisphere by the 133Xe-inhalation method. Intrahemisphere, interhemisphere, and global rCBF were generally similar across phonation tasks and did not yield appreciable differences among the nonsingers and the singers. 相似文献

Traditional definitions of feminism do not hold for some black women like Mary McLeod Bethune who had to overcome the dual burdens of race and sex in order to build a school for black girls in the racially tense South during the early part of the 20th century. Ever a pragmatist, Bethune seized the opportunity offered by the rhetoric of domesticity and certain stereotypical views of blacks in order to advance the higher cause of uplift and self-sufficiency for black women through education. 相似文献

The main aims of this review were to assess(1) the likelihood of learners making spontaneous use of verbal mnemonics, and (2) the extent to which learners will benefit from using verbal mnemonics. Over 60 investigations of verbal mnemonics were reviewed, most of which concentrated upon sentence mnemonics or first-letter mnemonics; although many of the studies used students as subjects, the review also considers the value of verbal mnemonics for schoolchildren, mentally handicapped people, brain-injured patients, and the elderly. On the whole, verbal mnemonics are relatively popular internal memory aids and, when compared to standard control conditions such as rehearsal, appear to be effective learning strategies for most of the populations studied, although mentally handicapped people and schoolchildren may find it difficult to produce effective mnemonics themselves; additionally, students and schoolchildren can benefit from the use of mnemonic sentences as part of more complex techniques. Comparisons between verbal mnemonics and other memory-aiding strategies have, however, given more equivocal results. A number of areas for future research are identified. In particular it is hoped to see a development of recent trends to use non-student subject, and to investigate the applicability of verbal mnemonics outside the laboratory. 相似文献

HyperCard (Atkinson, 1987) is a new development environment for the Macintosh that shows promise for use in psychological research and testing. In this paper, we discuss the development of HyperCard stackware with which a block-design task similar to that of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) can be administered. The reliability and validity of the computerized block-design task was evaluated by administering both the computerized task and the WAIS-R subtest to college undergraduates. Results indicated that the computerized task’s reliability compared favorably with that of the WAIS-R subtest. Validity coefficients were equivocal; although an elapsed-time measure showed moderate correlation between the tasks, the numbers of designs correctly completed in each condition were not significantly correlated. 相似文献

An electronic spreadsheet simulator can be used to enable students to conduct simulated microelectrode recording experiments. In addition, it can be used both to let students explore the operation of models of hypothetical neural networks and to let them design and develop their own neural models. 相似文献
