This paper contrasts two views about the relationship between the processes of access and mapping in analogymaking. The pattern of transfer of learning of luminance- (LM) and contrast-modulated (CM) motion is diagnostic of how their respective processing pathways are integrated. The standard practice of reducing every same-different data set to two numbers (hits and false alarms) is wasteful, because the response pattern to all four stimulus pairs carries information about the decision rule adopted by the observer. The Beginning (2017). Two hypotheses are examined: modification of early cortical representations versus task-specific selective reweighting. Most theories address only accuracy data and tacitly assume that perceptual learning is a monolithic phenomenon. Columbus, 10 Townshend Hall Alexander A. Petrov and Barbara Anne Dosher University of California, Irvine Zhong-Lin Lu University of Southern California The mechanisms of perceptual learning are analyzed theoretically, probed in an orientation-discrimination experiment involving a novel nonstationary context manipulation, and instantiated in a detailed computational model.
