Humans are remarkably adept at recognizing objects across a wide range of views. A
notable exception to this general rule is that turning a face upside down makes it particularly …

To better understand how the visual system makes use of information across spatial scales
when identifying different kinds of complex patterns, we measured human and ideal contrast …

Discriminating the direction of motion of a low-contrast pattern becomes easier with increasing
stimulus area. However, increasing the size of a high-contrast pattern makes it more …

Random dot cinematograms were used to probe motion perception in human observers
ranging from 23 to 81years of age. Stimuli were either broadband directional Noise, which …

We examined the contribution of optical and photoreceptor properties as well as receptor
pooling to eccentricity-dependent variations in spatial vision by comparing the performance of …

The visual system is constantly faced with the problem of identifying partially occluded
objects from incomplete images cast on the retinae. Phenomenologically, the visual system …

Conflicting results have been reported about the earliest “true” ERP differences related to
face processing, with the bulk of the literature focusing on the signal in the first 200 ms after …

The current study tested the widespread assumption that holistic processing is important for
the identification of upright faces. In two experiments, we show that (a) there are large …

Performance in perceptual tasks often improves with practice. This effect is known as ‘perceptual
learning,’ and it has been the source of a great deal of interest and debate over the …
