From Dialog's PsychINFO database the number of studies with 6 species reported in the Psychological Abstracts was calculated for each year from 1967 to 1988. Also, the number of studies with an additional 11 species were calculated for each year from 1973 to 1988. A hand search in the Journal of the Experimental Analysis of Behavior and Learning and Motivation was also conducted to explore trends in studies on 12 species from 1970 to 1987. The numbers of studies on many species (e.g., baboons, bats, chimpanzees, dolphins, gerbils, guinea pigs, gorillas, hamsters, lemurs, mice, pigeons, rats, seals, and snakes) have remained stable. There has, however, been a steady decline in the numbers of studies on selected species (e.g., cats, dogs, and rabbits). Possible reasons for changing trends in studies on selected species include: increased costs, the cognitive emphasis in psychology, and arguably, animal rights activism. 相似文献

James Bohman has succeeded in reinvigorating the old debate over explanation and understanding by situating it within contemporary discussions about sociological indeterminacy and complexity. I argue that Bohman's preference for a paradigm based on Habermas's theory of communicative action is justifiable given the explanatory deficiencies of ethnomethodological, rational choice, rule-based, and functionalist methodologies. Yet I do not share his belief that the paradigm is preferable to less formalized models of interpretation. 相似文献

An adult, with a puppet held at shoulder height on either side (within the infant's visual field), interacted with 3- to-6-month-olds, turning her head intermittently to talk to a puppet. Seventy- three percent of infants' first eye-turns were in the direction of the adult head-turn. 相似文献

In English, counting-out rhymes, such as “Eenie Meenie,” vary little over retellings. Recall is not rote but is sensitive to the structure of the genre. To test the generality of this finding, a sample of Romanian rhymes was collected. Although there was no overlap with the English rhymes, the corpus of rhymes collected had similar structure in terms of number of lines, repeating words, rhyme, alliteration, and the inclusion of nonsense words. Variation within rhymes preserved the poetic structure of the genre. The results suggest that verbatim recall can be schema driven if there is sufficient structure. 相似文献

A Chinese advantage over Americans was found for economically relevant computational and reasoning abilities in arithmetic for groups of 6th- and 12th-grade students matched or equated on general intelligence. No cross-national difference for computational or reasoning abilities was found for samples of older (60- to 80-year-old) Chinese and American adults equated on general intelligence. The pattern of change in arithmetical competencies across cohorts suggests that the Chinese advantage in 6th and 12th grade is due to a cross-generational decline in competencies in the United States and a cross-generational improvement in China. 相似文献

The association of relationship satisfaction to asthma-related illness factors was examined among 46 couples in which one person had asthma of mild-to-moderate severity. The asthma-related illness factors included measures of disease severity, functional status, and medical utilization. More asthma severity and greater use of asthma medications accounted for 27% of the variance in relationship satisfaction. These results diverge from the general notion that more illness should be associated with more relationship distress. The findings are discussed in the context of the potentially buffering effects of the relationship satisfaction among the couples in the present sample against the stress of a chronic illness. 相似文献

Although neuropsychology continues to grow as a valued service in most medical specialties, because of its multiple uses with diverse populations, it is necessary to evaluate the specialty critically in order to ensure continued future success. This article reviews areas in which neuropsychology is most firmly established, potential growth areas, and likely obstacles to success in the future. Suggestions are provided for ways in which neuropsychology can be improved/adapted in clinical, business, research, and training areas.

This paper describes the basic elements of practice development and management within the academic medical setting. These include assessment of the market environment, both in the community and within the medical setting, product development, marketing, budget basics, quality, managed care negotiations, and finding time to do research in a financially-driven health care system. 相似文献
