Perceptual separability, decisional separability, and the identification-speeded classification relationship.
Three observers participated in several sessions of identification and speeded classification. Predictions from F. G. Ashby and W. T. Maddox's (1994a) response time (RT) theory of speeded classification were tested. A key theoretical concept is decisional separability (DS), that is, that the decision about the level of 1 component does not depend on the perceived value of the other component. T...

متن کاملTWo Kinds of Global Perceptual Separability and Curvature
It is easy to appreciate that by moving the touching finger along objects, the sequence in which-the impressions of the object are presented becomes known; that this sequence shows itself to be independent of whether one feels with this or with that finger; that, furthermore, it is not a single-channeled, determined series, whose elements one must again and again traverse forward or backward in...
متن کاملSufficiency, Separability and Temporal Probabilistic Models
Suppose we are given the conditional proba bility of one variable given some other vari ables. Normally the full joint distribution over the conditioning variables is required to determine the probability of the conditioned variable. Under what circumstances are the marginal distributions over the conditioning variables sufficient to determine the probabil ity of the conditioned variable? Su...
متن کاملCategorization training increases the perceptual separability of novel dimensions.
Perceptual separability is a foundational concept in cognitive psychology. A variety of research questions in perception - particularly those dealing with notions such as "independence," "invariance," "holism," and "configurality" - can be characterized as special cases of the problem of perceptual separability. Furthermore, many cognitive mechanisms are applied differently to perceptually sepa...
