Lateral interactions between spatial channels: Suppression and facilitation revealed by lateral masking experiments
We measured contrast detection thresholds for a foveal Gabor signal flanked by two high contrast Gabor signals. The spatially localized target and masks enabled investigation of space dependentExpand

The architecture of perceptual spatial interactions
Lateral interactions between spatial filters were explored with a lateral masking paradigm. Contrast sensitivity (two-alternative forced-choice) for a Gabor signal in the presence of two flankingExpand

Improving vision in adult amblyopia by perceptual learning.
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 such asExpand

The pattern of lateral interactions in the primary visual cortex, which has emerged from recent studies, conforms to the grouping rules of similarity, proximity, smoothness and closure. The goal ofExpand

Enhancing the contrast sensitivity function through action video game training
The contrast sensitivity function (CSF) is routinely assessed in clinical evaluation of vision and is the primary limiting factor in how well one sees. CSF improvements are typically brought about byExpand

Facilitation and suppression of single striate-cell activity by spatially discrete pattern stimuli presented beyond the receptive field.
Visual stimulation of a region outside the receptive field of single cells in visual cortex often results in the modulation of their responses. The modulatory effects are thought to be mediatedExpand

ADHD subjects fail to suppress eye blinks and microsaccades while anticipating visual stimuli but recover with medication
Oculomotor behavior and parameters are known to be affected by the allocation of attention and could potentially be used to investigate attention disorders. We explored the oculomotor markers ofExpand
