The representation modification hypothesis of perceptual learning attributes the practice-
induced improvements in sensitivity and/or discriminability to changes in the early visual …

We investigated visual direction discrimination under the influence of motion aftereffect
(MAE). Participants in each experiment first adapted to a horizontally drifting grating before …

One hypothesis in visual perceptual learning is that the amount of transfer depends on the
difficulty of the training and transfer tasks (Ahissar & Hochstein, 1997; Liu, 1995, 1999) …

When human subjects discriminate motion directions of two visual stimuli, their
discrimination improves with practice. This improved performance has been found to be …

Perceptual learning has been widely used to study the plasticity of the visual system in
adults. Owing to the belief that practice makes perfect, perceptual learning protocols usually …

Several previous psychophysical and neurophysiological studies have investigated the
separate effects of attention and adaptation on visual processing. Here, we investigated the …

Perceptual learning of motion discrimination has long been believed to be motion direction
specific. However, recent studies using a double-training paradigm, in which the to-be …

Perceptual learning of motion direction discrimination is generally thought to rely on the
middle temporal area of the brain (MT/V5). A recent study investigating learning of motion …

The motion aftereffect (MAE) is the perception of illusory motion following extended
exposure to a moving stimulus. The MAE has been used to probe the role of attention in …

Here, we report on the long-term stability of changes in behavior and brain activity following
perceptual learning of conjunctions of simple motion features. Participants were trained for 3 …
