Five experiments explored short-term memory and incidental learning for random visual
spatio-temporal sequences. In each experiment, human observers saw samples of 8 Hz …

Perception is often influenced by context. A well-known class of perceptual context effects is
perceptual contrast illusions, in which proximate stimulus regions interact to alter the …

Perceptual learning changes the way the human visual system processes stimulus
information. Previous studies have shown that the human brain's weightings of visual …

Motion detection is a fundamental property of the visual system. The gold standard for
studying and understanding this function is the motion energy model. This computational …

Radial frequency (RF) patterns are circular contours where the radius is modulated
sinusoidally. These stimuli can represent a wide range of common shapes and have been …

The human mind can remarkably imagine objects that it has never seen, touched, or heard,
all in vivid detail. Motivated by the desire to harness this rich source of information from the …

In this paper, we applied a reverse correlation approach to study the features that humans
use to categorize facial expressions. The well-known portrait of Mona Lisa was used as the …

In the following thesis, I develop and apply a parametric systems identification framework to
study how visual stimuli are represented at the single-neuron, multi-neuron, and …
