One of the processes supposed to take place during development toward medical expertise is knowledge encapsulation. In this process detailed biomedical concepts are gradually clustered together and reorganized under fewer, clinically relevant terms. A large-scale investigation was made of the process of biomedical knowledge application using…

Previous research has shown that 3- to 4-month-old infants form a global categorical representation for cats that includes female lions, whereas 6- to 7-month-old infants differentiate between cats and lions. Three experiments using familiarization-novelty preference procedures attempted to determine whether the differentiation of a global…

The Boehm Test of Basic Concepts (BTBC) (Boehm, 1971) was administered to 99 children (ages 7-10) who had been diagnosed as learning disabled and attended special schools in the New York area. It was hypothesized that the learning disabled children would exhibit a delay in the acquisition of the basic concepts, but would display a similar order of…

Two concept learning experiments were performed in which the stimulus dimensions were applicable to persons. (Editor)

Examines questions about reported findings that the natural number concept derives from a prior understanding of ordination rather than a prior understanding of cardination. (GO)

The nature of the affinitive relationships expressed through thesaural related terms were studied in ten thesauri and analyzed in terms of Farradane's relational indexing operators and the four fundamental categories of concepts derived by the Classification Research Group in England. (Author/LS)
