This investigation compares overt judgments about tenable hypotheses to choices in a concept identification task, as a function of stimulus similarity on successive trials. Two mathematical models are tested: (a) A 1-element local consistency version of Restle's concept identification model and (b) the same model with two additional passive states…

Projects that soon a complete mechanistic understanding of simple forms of learning will be available. Describes some of the recent advances in neuroscience and psychology in understanding the changes in neural circuits that occur during certain behavioral situations. Suggests that learning involves the activation of second messenger systems. (TW)

In man-computer communication, the computer responds only as it is programed to respond. A human's response is more complicated because it depends on the "pre-programed" ways that humans process information. The three functions a man performs on received information are conservation (in which messages are retained whole), reduction (in which…
