Two studies explored the hypothesis that young children perceive integrally some stimuli that older children perceive separably. In both experiments, kindergarten, second- and fifth-grade children were required to classify sets of stimuli that varied in size and brightness. (SB)

The study reported in this paper developed a categorization of teacher physical motion in relation to verbal actions and analyzed two random samples of such motion as a basis for posing ten hypotheses concerning teacher nonverbal behavior. (MJB)

Three estimates of the probabilities of correct classification in predictive discriminant analysis were computed using mathematical formulas, resubstitution, and external analyses: (1) optimal hit rate; (2) actual hit rate; and (3) expected actual hit rate. Methods were compared using Monte Carlo sampling from two data sets. (Author/GDC)

Reports the results of one study in which parents taught their two- to four-year-olds basic and superordinate concepts, and another, in which they taught them subordinate concepts. Parents' teaching styles were analyzed in terms of their usefulness for children who are attempting to learn about principles of hierarchical classification. (AS)

The study reviewed Sanskrit books written between 1500 BC and 1904 AD concerning diseases, speech pathology, and audiology. Details are provided of the ancient Indian system of disease classification, the classification of speech sounds, causes of speech disorders, and treatment of speech and language disorders. (DB)
