Subjective similarity holds a prominent place in many psychological theories, influencing
diverse cognitive processes ranging from attention and categorization to memory and …

Visual attentional deficits are frequently reported in patients with mild traumatic brain injury
(TBI). In the present study, the ability to orient visual attention (ie, the use of endogenous and …

The visual system is exposed to a vast number of shapes and objects. Yet, human object
recognition is effortless, fast and largely independent of naturally occurring transformations …

Radial frequency (RF) patterns, which are sinusoidal modulations of a radius in polar
coordinates, are commonly used to study shape perception. Previous studies have argued …

Radial frequency (RF) patterns, created by sinusoidal modulations of a circle's radius, are
processed globally when RF is low. These closed shapes therefore offer a useful way to …

Human visual cortex is partitioned into different functional areas that, from lower to higher,
become increasingly selective and responsive to complex feature dimensions. Here we use …

We studied the role of ventral visual cortex areas in processing color and shape information
during memorizing these characteristics. The participants (22 people) were presented with …

Purpose: To measure changes in visual performances and optical quality in myopic children
during the first month of wearing orthokeratology lens, and to reveal the association between …

During visual search, attention is guided by specific features, including shape. Our
understanding of shape guidance is limited to specific attributes (closures and line …

Using a radial frequency discrimination task that has not been tested in many previous
studies, we examined the dependence of the pattern radius (4 to 16 deg) on the radial …
