Lynne Werner Olsho 《Infant behavior & development》1985,8(4):371-384
The results of an earlier study (Olsho, 1984) indicated that 5- to 8-month-old infants were relatively better at discriminating among high-frequency pitches than low. In the present study, sensory and nonsensory explanations for that effect were evaluated by examining infants' performance in a task requiring similar sensory processing but differing in the demands placed on processes such as memory. Infants' ability to resolve frequency was tested using a tonal masking paradigm, the psychophysical tuning curve. Twenty-four infants were tested at probe frequencies ranging from 500 to 4000 Hz; a group of young adults served as a comparison. Masked and unmasked thresholds were estimated using the visually reinforced head turn procedure in conjunction with an adaptive psychophysical method. Although infants' tuning curves fell below those of adults (indicating poorer performance), the widths and slopes of the infants' curves were not different from the adults'. Moreover, the difference between age groups remained constant across probe frequencies. These findings imply that by 5 months of age, the infant's ability to resolve sound frequency is similar to the adult's. 相似文献

Starting from Lennart Sjöberg's serial scoring of the Color-Word Test and his critical review of the test, the possibilities of attaining better reliability estimates are briefly surveyed. As a simple step, the orthogonalization of the regression model is suggested. Ways of maximizing the reliability estimate are demonstrated. On the basis of 261 subjects from five differing subsamples, clinical and control groups, the reliability estimates of the oblique system of the orthogonalized system and of the maximum reliability solutions are compared empirically. The significance of the results for test theoretic evaluation of the Color-Word Test is discussed. 相似文献

Joseph L. Wolff 《Intelligence》1980,4(2):165-170
Kamin (1980) has contended that arguments presented in Wolff (1979) are too weak to justify “resuscitating the selective migration debate.” Although Kamin's (1980) critique points up the need for closer scrutiny of the cumulative-deficit phenomenon, it fails to refute Wolff's (1979) conclusion that selective migration is partly responsible for the North-South black IQ differential. 相似文献

The present experiment investigated semantic information extraction in parafoveal word perception. An ambiguous word (bank) was presented in foveal vision, and simultaneously a disambiguating word (water, money) was presented in the parafovea. Subjects were required to make a forced choice between two phrases, and the task was constructed so that a correct choice could be made if semantic information about both the foveal and parafoveal word had been obtained. However, the results indicated that the forced-choice results could be explained by two factors: identification of the parafoveal word and correct guessing. Hence, it was concluded that those models of reading which rely on unconscious semantic preprocessing of parafoveal words were not supported. 相似文献

ABSTRACT The aim of this study was to test whether the concept of an altruistic personality was valid for first aiders who intervened to help the victims of a traffic accident. We derived a number of relevant personality variables that should be related to the willingness to administer first aid. These include locus of control, social responsibility, belief in a just world, empathy, and instrumentality. We obtained data from proven first aiders who had intervened after a traffic accident. Thirty-four of these first aiders were matched to respondents from a subject pool on the basis of sex, age, and socioeconomic status. In addition, the willingness of these respondents to offer help after a traffic accident was taken into account. Only people who indicated that they had witnessed an accident and had not helped were included in the control group. Multivariate analyses of variance and covariance indicated that proven first aiders deviated from the control group on several dimensions: They described themselves as more internal, believed more in a just world, and emphasized more social responsibility and empathy. 相似文献

Summary Effects of learning can show up in a direct, i. e., an explicit, way or they can be expressed indirectly, i. e., in an implicit way. It was investigated whether motor processes underlie effects of repetition priming in haptic information exploration. In the test phase, blindfolded subjects had to handle objects in order to answer questions as fast as possible about their properties (e.g., temperature, texture, weight, or form), exploring the object with their hands. Some of the objects were old ones (presented in a study phase); others were added as new objects to the test phase. In addition, recognition judgements were required. The results demonstrated reliable effects of repetition priming in terms of reaction times to old, in comparison with new, objects for subjects who had been treated the same way in the study phase (active touch). Passive touch at encoding or studying the names or the visible objects themselves did not lead to effects of repetition priming in the test phase. On the other hand, performing adequate hand movements during the study improved recognition memory. The role of motor processes in indirect and direct tests of memory is discussed and related to research on memory of action events. 相似文献

This study examined the use of oral contraceptives in a sample of sexually active college women. The analytic approach employed was based on Fishbein's model for the prediction of behavior, which emphasizes perceived consequences and normative influences. It was found that each of these factors was significantly related to use of oral contraception, and that a stronger relationship was obtained when both components were combined. Results suggested that nonusers are more Likely to associate oral contraception with unhealthful consequences than are users, and that users believe employment of this method enhances their sexual satisfaction. It was also suggested that the opinions of these young women's partners and close friends, but not of their parents, are reflected in respondents' use of the pill. These results were compared with earlier findings on the correlates of intentions to use oral contraceptives, and applied implications were discussed. 相似文献

Following a rise in the life expectancy of cystic fibrosis (CF) patients, many adults with CF form couple relationships. Yet, dyadic coping has not been previously examined in people with CF. This study examined how adults with CF and their partners cope as a couple with the illness, and what meanings each partner and the couple as a unit attribute to the experience. Seventeen adult CF patients and their partners participated in separate semi‐structured in‐depth interviews. Two main patterns of dyadic coping with CF were identified as follows: cooperation and tension. For couples in cooperation, the marital relationship served as a resource for adaptive coping. These couples were characterized by similarities in their perception of the place of CF in their lives and of their roles in the marital relationship. Couples in tension described the couple relationship as strained by difficulty of accepting the disease, proliferation of negative emotions, and a sense of burden and loneliness in the process of coping. Findings point to the importance of mutual empathy, clear and accepted division of roles between the partners, and open communication for facilitating coping as a couple. 相似文献
