Performance on perceptual tasks improves with practice. Most theories address only
accuracy data and tacitly assume that perceptual learning is a monolithic phenomenon. The …

The functional form of performance improvements has been extensively studied in speeded
cognitive and motor tasks; in such tasks, reductions in response times have been …

Sensory judgments improve with practice. Such perceptual learning is often thought to
reflect an increase in perceptual sensitivity. However, it may also represent a decrease in …

When we think of learning, several prototypical ideas come to mind: the encoding of an item
in memory, the connecting of one idea to another, the connecting of a response to 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 …

We compared perceptual learning in 16 psychophysical studies, ranging from low-level
spatial frequency and orientation discrimination tasks to high-level object and face …

Perceptual learning is defined as long‐term improvement in perceptual or sensory systems
resulting from repeated practice or experience. As the number of perceptual learning studies …

Perceptual learning is characterized by an improvement in a perceptual task following
practice. Several studies have demonstrated that top-down processes, such as attention and …

Abstract We investigate Ornstein–Uhlenbeck and diffusion processes with variable drift rates
as models of evidence accumulation in a visual discrimination task. We derive power-law …

The mechanisms of perceptual learning are analyzed theoretically, probed in an orientation-
discrimination experiment involving a novel nonstationary context manipulation, and …
