Vision provides us with an ever-changing neural representation of the world from which we
must extract stable object categorizations. We argue that visual analysis involves a …

The role of feedback in perceptual learning is probed in an orientation discrimination
experiment under destabilizing non-stationary conditions, and explored in a neural-network …

In this study, we applied the external noise method and the PTM model to identify
mechanisms underlying performance deficits in amblyopia. Amblyopic and normal …

Perceptual learning is an improvement in perceptual task performance reflecting plasticity in
the perceptual system. Practice effects were studied in two object orientation tasks: a first …

Contemporary theoretical accounts of perceptual learning typically assume that observers
are either unbiased or stably biased across the course of learning. However, standard …

In brain mapping studies of sensory, cognitive, and motor operations, specific waveforms of
dynamic neural activity are predicted based on theoretical models of human information …

This study consists of two parts related to perceptual learning and perception respectively. In
the first part, we examined visual learning at multiple levels of the visual system: the one that …

This paper presents a summary of an effort to use computational modeling to link behavioral
and neurophysiological levels of analysis in support of tests of hypotheses regarding a …
