Theorists concerned with the nature of professionalism and researchers investigating professionals in the work environment often assume that professional occupations are a unique occupational type. To test this assumption, an occupational taxonomy based on nine dimensions of professionalism was derived empirically. The taxonomy represented expectations only to a moderate degree. Several implications were noted for the use of occupational taxonomies in the generalization of research findings on one occupational group to other occupational groups in the same classification. 相似文献

Twelve 10- to 16-week-old infants were presented with nursery rhymes spoken with speech sounds and lip movements in-synchrony and out-of-synchrony by 400 msec. Two observers measured the amount of time the infants did not attend to the two types of stimuli. The results showed that the infants attended significantly less to the out-of-synchrony presentation than to the in-synchrony presentation. This finding was interpreted as an indication that young infants are aware of the congruence between lip movements and speech sounds. 相似文献

The relationship between men's endogenous levels of testosterone and their penile responses to erotic stimuli. 总被引:1,自引:0,他引:1
The endogenous levels of testosterone of six nonclinical, sexually functional men were compared to the magnitude and speed of development of their objectively measured penile erections to repeated presentations of an erotic film und to their self-reported sexual activity. Plasma testosterone concentrations were significantly correlated with two measures of the magnitude of film-elicited sexual arousal (i.e., both peak and mean erection) and with one measure of the speed of development of sexual arousal (i.e., the latency to 90% of full erection) but not with the other (i.e., the latency to 20% of full erection). There was also a significant inverse relationship between testosterone levels and their reported frequency of orgasm by any means. but the reported time from their last orgasm was not related to testosterone levels. 相似文献

The construct of general intelligence is discussed in a number of different contexts. The fundamental empirical basis for it is the positive trend among the smallest correlations among cognitive measures. Differences among factor models which recognize this in different ways are discussed. Evidence for the general factor in intelligence is also found in the difficulty in finding evidence for differential validity of tests from one criterion to another. Performance on Piagetian tasks reflects mainly general intelligence. Individual differences in aural comprehension of language anticipate later individual differences in intellectual development. Selective forces which produce differences among schools operate largely on the general factor. To the extent that there is a genetic contribution to individual differences on cognitive tests, it appears to be to the general factor variance. Social class differences among whites appear to be largely on the general factor, but black-white differences require other dimensions. Although the general factor is, in a sense, real, it is not interpreted as an entity within the organism. Instead it is an abstraction resulting from the many genes, the many environmental pressures, and the many neural structures involved in the wide variety of human behaviors which can be labelled cognitive or intellectual. 相似文献

The purpose of this study was to compare audio and audiovisual techniques of analyzing stuttering behavior using a recently developed index of agreement (Young, 1975). Twenty speech pathologists identified moments of stuttering for ten adult stutterers using both audio and audiovisual methods. Although no statistically significant differences existed between the two conditions, the listeners had more difficulty identifying moments of stuttering during the audio condition when mild stutterers were used. 相似文献

The writing patterns of two adults diagnosed as having congenital neurological impairment were submitted to linguistic analysis. The written work of these persons was found to contain errors incompatible with those of undereducated native speakers of English but somewhat analogous to errors of aphasics: tense, plural, and possessive endings are absent; articles and prepositions are absent or are used incorrectly; subordinating words are absent or incorrectly used. Yet the oral performance of these persons was syntactically unremarkable. It seems, therefore, that congenital neurological damage can affect the written performance while leaving the oral performance comparatively intact. 相似文献

Adults need to discriminate between stimuli and recognize those previously seen. For faces, feature changes (e.g., different eyes) and spacing changes (e.g., distances between eyes) are important cues. In two experiments, we assessed the influence of these on discrimination and recognition of houses, a commonly used control in face studies. In both experiments, discrimination was better for feature than spacing changes. Memory for spacing changes was generally poor but aided by extra learning and intermixing change types. Conversely, memory for features was good, especially when there were few houses, and change type was blocked. Unexpectedly, memory was best for differences that might signal something about occupants (e.g., changes to garden or bins), perhaps akin to hairstyles for faces. Overall, results are consistent with previous work showing poor discrimination of spacing in non-face objects and extends them to show that, unlike for faces, spacing differences are also not well remembered. 相似文献
