Abstract
The theory of direct learning characterizes perception of a given property as occupying a locus in an information space and characterizes perceptual learning as continuous movement in that information space toward a more optimal locus. Three experiments investigated whether such an information-based account of learning could be applied to perceptual learning in audition. The results of Experiment 1 showed that perception of length by audition could be characterized as occupying a locus in an information space consisting of inertial variables that constrain perception of length by dynamic or effortful touch. Experiments 2 and 3 showed that feedback about length led to predictable movements across the information space from less optimal to more optimal loci. Such results provide additional support for the theory of direct learning and suggest that convergence information may be modality independent.
