This study examined the development of the animate–inanimate (A–I) distinction in relation to other taxonomic categories in early childhood. Four‐ and 5‐year‐old children were administered two tasks measuring knowledge of taxonomic categories at various levels of inclusiveness. Across both matching‐to‐sample and object sorting tasks, the same pattern of categorization development was observed. Mastery of basic‐ and superordinate‐level categories was demonstrated by 4 years of age. Although 5‐year‐old children performed above chance on A–I level categories, their abilities were not as mature as those of adults. Results of this study support and extend previous studies investigating the development of children's understanding of naïve biology during the preschool years. 相似文献

Being married has generally been associated with better mental health for adult females, in part because of the social support derived from a primary network relationship. Without the benefit of a spouse, it would be expected that nonmarried adult females would have fewer sources of social support and concomitantly lower levels of psychological well-being. Focusing on selected network characteristics, this study analyzes the differences in social support available to a sample of 91 married and 183 nonmarried Black females residing in a metropolitan area. Results indicate that having a spouse has little influence on the number of socially supportive relationships or the most important sources of assistance with financial problems. A marital partner is a source of emotional support for married Black females, but only for less than one-third. Family members and extended kin are major sources of social support for Black females, irrespective of marital status. 相似文献
