How does the brain learn those visual features that are relevant for behavior? In this article,
we focus on two factors that guide plasticity of visual representations. First, reinforcers cause …

Object vision in human and nonhuman primates is often cited as a primary example of adult
plasticity in neural information processing. It has been hypothesized that visual experience …

Normal aging is associated with a degradation of perceptual abilities and a decline in higher-
level cognitive functions, notably working memory. To remediate age-related deficits …

Visual perceptual learning models, as constrained by orientation and location specificities,
propose that learning either reflects changes in V1 neuronal tuning or reweighting specific …

Perceptual learning often shows substantial and long-lasting changes in the ability to
classify relevant perceptual stimuli due to practice. Specificity to trained stimuli and tasks is a …

Perceptual learning of orientation discrimination is reported to be precisely specific to the
trained retinal location. This specificity is often taken as evidence for localizing the site of …

In the present study, we examined whether perceptual learning methods can be used to
improve performance of older individuals. Subjects performed a texture discrimination task …

A total of 29 patients with homonymous visual field defects without neglect practised visual
search in 20 daily sessions, over a period of 4 weeks. Patients searched for a single …

Much knowledge of sensory cortical plasticity is gleaned from perceptual learning studies
that improve visual performance [1–7]. Although the improvements are likely caused by …

We examined the impact of variability in speech stimuli on improvement of general
performance and on accessibility to low-level information as a function of practice. Listeners …
