▪ Abstract The visual image formed on the retina represents an amalgam of visual scene
properties, including the reflectances of surfaces, their relative positions, and the type of …

Issues concerning selective attention provoke new questions about visual segmentation,
and vice-versa. We illustrate this by describing our recent work on grouping under …

Most models of visual search, whether involving overt eye movements or covert shifts of
attention, are based on the concept of a saliency map, that is, an explicit two-dimensional …

Recent research [Parkhurst, D., Law, K., & Niebur, E., 2002. Modeling the role of salience in
the allocation of overt visual attention. Vision Research 42 (1)(2002) 107–123] showed that …

Visual detection and discrimination thresholds are often measured using adaptive
staircases, and most studies use transformed (or weighted) up/down methods with fixed step …

Practicing certain visual tasks leads, as a result of a process termed “perceptual learning,” to
a significant improvement in performance. Learning is specific for basic stimulus features …

Shifting attention away from a visual stimulus reduces, but does not abolish, visual
discrimination performance. This residual vision with'poor'attention can be compared to …

When we observe our visual environment, we do not perceive all its components as being
equally interesting. Some objects automatically and effortlessly “pop-out” from their …

Crowding, the difficulty in recognizing a letter flanked by other letters, has been explained as
a lateral masking effect. The purpose of this study was to examine the spatial-frequency and …

The integration of local image features into global shapes was investigated in monkeys and
humans using fMRI. An adaptation paradigm was used, in which stimulus selectivity was …
