The major question which this research examinedis whether informal integration is likely to result incareer advancement and perceived resources within twodifferent organizational contexts (plural and multicultural). Specifically, we examinedinteractions of race, gender, and organization type onthe above two outcome variables. In pluralorganizations, employees are expected to assimilate intothe dominant culture, while in multicultural organizations,cultural change for the individual and the organizationis reciprocal. Hypotheses were tested with a combinedsample of 101 men, 35 women, 29 persons of color, and 107 whites. Results indicated that,congruent with predictions, greater social integrationoccurred in an organizational context in which valuingdifferences was a priority. Further, the influence of informal integration on career advancement wasstill important even after controlling for suchvariables as age, organizational tenure, education, andhierarchical level within the organization. Implications of these findings for valuing diversity arediscussed. 相似文献

In the late nineteenth century and through much of the twentieth century, the notion of the early developmental autonomy of motor behavior pervaded behavioral embryology and the developmental psychology of infant behavior. In the midst of this predeterministic climate of opinion concerning motor development, Myrtle McGraw briefly and tentatively broached the probabilistic epigenetic notion of a bidirectional or reciprocal relationship between structural maturation and function, whereby structural maturation of the nervous system is influenced by functional activity as well as the other way around. Myrtle McGraw thus anticipated our current understanding of the role of experience in the cortical and motor maturation of infants in the first year of postnatal life. It is all the more remarkable that she made this contribution when the theoretical climate of opinion was epitomized by predeterministic epigenetic thinking. In the same vein, McGraw's second unrecognized contribution is her clear formulation of a suitably flexible critical period concept in 1935, one that is consonant with our current understanding. 相似文献

Abstract— Experiments in cross-modal matching suggest that smells can be arranged by odor qualify along the color dimensions of hue and lightness. Here we report that subjects readily adjust the loudness-equalized pitch of on auditory tone to match a stimulus odor. The results allow odors to be arranged in sequence by their pitch-equivalents. The tone matches appear to be based on perceptual feature of olfaction other than stimulus intensity or pleasantness. The results suggest that features of odor quality may be more accessible and structured than previously acknowledged. 相似文献

Nicotinic receptor dysfunction and impaired semantic memory occur early in Alzheimer's disease patients (AD). Previous research implied that nicotine's ability to enhance alertness, arousal, and cognition in a number of nonclinical populations was a function of its ability to stimulate CNS nicotinic cholinergic receptors. In this study it was hypothesized that transdermal administration of nicotine would increase both regional cerebral glucose metabolism (rCMRglc) and semantic memory (as assessed by verbal fluency). Two mild AD and two elderly controls underwent positron emission tomography scanning during a double blind nicotinic agonist verbal fluency challenge procedure. rCMRglc increases occurred in both AD patients, but not controls. In the two AD patients, verbal fluency scores increased by an average of 17%. One elderly control's verbal fluency increased, and the other decreased. These findings suggest that nicotine's effect on metabolism and verbal fluency is due to its ability to stimulate the cholinergic system. 相似文献
