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

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

ABSTRACT Lamiell's (1981) “idiothetic” index has been praised for raising significant conceptual and methodological issues, but Paunonen and Jackson (1986a) indicated that it might not provide any unique information The current study demonstrates that the unique value of the idiothetic index relative to the ipsative, normative, and normative-ipsative indices is dependent in part upon what information is collected and how it is analyzed Subjects completed inventories on three occasions that assessed seven dispositional variables Interindividual analyses indicated a high correlation between the idiothetic method and two of the other models, whereas intra-individual analyses indicated a much lower degree of correlation Intra-individual analyses indicated that the idiothetic method produced higher temporal stability coefficients The idiothetic index provides information not contained in a normative index and it may be more useful to personality researchers for the assessment of temporal stability and for the assessment of traits with extreme base rates 相似文献

We investigated the influence of teacher wait-time and intertrial interval durations on the performance of 4 multiply handicapped students during instruction in 10 skills. Four experimental conditions were evaluated: long wait-time and long intertrial interval, long wait-time and short intertrial interval, short wait-time and long intertrial interval, and short wait-time and short intertrial interval. Instructors attempted to keep short intervals as close as possible to 1 s and long intervals as close as possible to 10 s for both variables. Results showed that student performance was superior under the long wait-time conditions irrespective of the length of the intertrial interval. 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
