Perceptual learning can be defined as practice-induced improvement in the ability to
perform specific perceptual tasks. We previously proposed the Reverse Hierarchy Theory as …

Attention exhibits characteristic neural signatures in brain regions that process sensory
signals. An important area of future research is to understand the nature of top-down signals …

Reports published in Vision Research during the late years of the 20th century described
surprising effects of long-term sensitivity improvement with some basic visual tasks as a …

Practising simple visual tasks leads to a dramatic improvement in performing them. This
learning is specific to the stimuli used for training. We show here that the degree of …

Research in the neurosciences continues to provide evidence that sleep plays a role in the
processes of learning and memory. There is less of a consensus, however, regarding the …

We report evidence from visual search that people can develop robust representations for
highly overlearned faces. When observers searched for their own face versus the face of an …

The basal ganglia are equipped with inhibitory and disinhibitory mechanisms that enable a
subject to choose valuable objects and actions. Notably, a value can be determined flexibly …

Visual texture discrimination has been shown to induce long-lasting behavioral
improvement restricted to the trained eye and trained location in visual field [Karni, A. & Sagi …

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

To evaluate the effects of perceptual learning on contrast-sensitivity function and visual
acuity in adult observers with amblyopia, 23 anisometropic amblyopes with a mean age of …
