Perceptual learning improves perceptual sensitivity through training. The learning curve is
typically sampled in blocks of trials because of the number of trials required for each …

The functional form of the learning curve is one of the fundamental characterizations of
perceptual learning. Dosher & Lu (2007) compared a number of functional forms for their …

The degree of transfer/specificity is a fundamental property of perceptual learning. Many
conclusions about the level and mechanisms of perceptual learning depend critically on the …

The learning curve in perceptual learning is typically sampled in blocks of trials, which could
result in imprecise and possibly biased estimates, especially when learning is rapid …

Prominent models of perceptual learning (eg, Gold, Bennett, & Sekuler, 1999; Dosher & Lu,
1999) assume an internal response criterion that is stable across time. In addition, many …

Performance improvement in perceptual learning may be measured as increases in
accuracy for a constant stimulus, or as reductions in threshold contrast for a given threshold …

In many perceptual learning studies, detection and discrimination thresholds are assessed
using adaptive (eg staircase) methods. The measured decrease in threshold is interpreted …

In the perceptual learning literature, researchers typically focus on improvements in
accuracy, such as proportion correct or dprime. In contrast, researchers who investigate the …
