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 …

Second-order textures—patterns that cannot be detected by mechanisms sensitive only to
luminance changes—are ubiquitous in visual scenes, but the neuronal mechanisms …

We measured visual-adaptation strength under variations in visual awareness by
manipulating phenomenal invisibility of adapting stimuli using binocular rivalry and visual …

Crowding is the identification difficulty for a target in the presence of nearby flankers. Based
on psychophysical findings, many theories have been proposed to explain crowding at …

The influence of selective attention on visual processing is widespread. Recent studies have
demonstrated that spatial attention can affect processing of invisible stimuli. However, it has …

It has recently been suggested that visual spatial attention can only affect consciously
perceived events. We measured the effects of sustained spatial attention on orientation …

We evaluated binocular summation, eye dominance, and learning in the Trivector and
Ellipses procedures of the Cambridge Colour Test (CCT). Subjects (n= 36, 18–30 years old) …

Performance on the texture discrimination task improves with practice but was also shown to
decrease between closely spaced sessions. Here we explored immediate changes in …

A variety of cues can differentiate objects from their surrounds. These include “first-order”
cues such as luminance modulations and “second-order” cues involving modulations of …

Ivry [Ivry, RB (1996). The representation of temporal information in perception and motor
control. Current Opinion in Neurobiology, 6, 851–857.] proposed that explicit coding of brief …
