Classification-image analysis has proven to be a valuable tool for revealing features used to
perform visual tasks in noise. We use this methodology to investigate how the magnitude of …

Continuous psychophysics is a newly developed technique that allows rapid estimation of
visual thresholds by asking subjects to track a moving object, then deriving the integration …

The response of motion-sensitive neurons to stimuli presented within their receptive field is
often affected by stimulation in the surrounding region. These effects have perceptually …

Classification images and bubbles images are psychophysical tools that use stimulus noise
to investigate what features people use to make perceptual decisions. Previous work has …

The phenomenon of visual stability is classically explained by an internal forward model
predicting the sensory consequences of an eye movement based on efference copy …

When a peripherally viewed stimulus is presented with flankers, observers' acuity for shape
generally decreases. We wondered whether a change in the locus of information accrual …

The choice of where to look in a visual scene depends on visual processing of information
from potential target locations. We examined to what extent the sampling window, or filter …

This study examined how correlated, or filtered, noise affected efficiency for recognizing two
types of signal patterns, Gabor patches and three-dimensional objects. In general …

We investigated whether the perceptual completion of illusory contours exhibits a vertical
bias (J. Pillow & N. Rubin, 2002). Experiments 1–3 measured completion with Pillow and …

Attention as a serial contiguous spotlight has met challenges from parallel-noisy models and
evidence that attention can split across multiple locations. To assess this question, this study …
