| Abstract: | Notes that distances between stimuli and compactness of stimulus subsets are pervasive determiners of discrimination and classification performance. Contrary to B. Crassini (see record 1986-26308-001), these factors are sufficient to account for the major patterns in the chronometric data of the present authors (see PA, Vols 61:259 and 71:3057). Other factors, such as the dichotomous one distinguishing what Crassini terms unitary and nonunitary subsets, may exert some additional influence. But a convincing demonstration would require formulation of a quantitative model capable of being pitted against the present authors' distance-based model within the context of their entire body of data.
