Several toxic agents were compared in order to test the effect of various types of illness in producing learned taste aversions. After a 10-min sucrose drinking trial, groups of rats were injected intraperitoneally with lithium chloride or with a strong, near lethal dose of a rodenticide. Strong sucrose aversions were acquired by groups injected with lithium chloride, copper sulfate, sodium fluoroacetate, or red squill, and very weak or no aversions were learned by groups injected with thallium, warfarin cyanide, or strychnine. The results were discussed in terms of onset of symptoms, duration of symptoms, and kinds of physiological effects necessary to produce aversions. It was concluded that the effects of different drugs may be mediated by different physiological systems learned taste aversions. 相似文献

Holland (1973) classified all occupations into six occupational fields: Realistic, Investigative, Artistic, Social, Enterprising and Conventional. Roe (1956) classified occupations into Service, Business, Organization, Technology, Outdoor, Science, General Cultural, and Arts and Entertainment fields. Two hundred seventeen Israeli ninth-grade students answered two interest inventories, one based on Holland's classification and one on Roe's classification. By means of a Smallest Space Analysis (SSA-I), a two-dimensional configuration was found. In this configuration the hypothesized parallel fields appear adjacent to one another and the general shape resembles the structure found earlier for each classification system separately. The findings indicate the possibility of incorporating results based on either classification. Some practical applications of the findings are discussed. 相似文献
