A summary of current theoretical work in the area of concept formation is presented with emphasis on the presentation of thinking in theory. Examination of the logic relating thinking to behavior leads to criticism of the tendency to subordinate "behavior" to underlying processes. The difficulties inherent in analyses of this type are that…

This paper contends that human organisms are not qualitatively different from infra-human ones. The same principles apply to the acquisition, maintenance and weakening of complex verbal skills as mathematics as to rats pressing bars or pigeons pecking windows. Two aspects of child research are assessment and training. Assessment involves…

It was found that not only did the children's language develop over the period, as judged syntactically and lexically, but they also showed an increasingly fluent control over their own style. All the children…

A research project of environmental learning in children is discussed. Most of the studies conducted during the research involved observation of children aged 3-12, in mapping and free environmental behavior, and in curricular experiments using perceptual surrogates for map-learning and macro-environmental conceptualization in the lower elementary…
