Triggerfish uses chromaticity and lightness for object segregation
Humans group components of visual patterns according to their colour, and perceive colours separately from shape. To find out if fish use colour for object segregation in a similar manner to humans, we used stimuli inspired by the Ishihara test for colour deficiency....
Objective measurement of eye alignment using eye tracking
Strabismus (“squint” or an “eye turn”) is a condition where the two eyes are not aligned. It affects about 1 in 20 children. Some patients with strabismus need surgery to align their eyes. Surgical success depends on having good measurements of strabismus angle, eye...
Hearing loss improves peripheral vision
Although it is widely believed that the loss of one sense (like hearing) improves other senses (like vision) there is little evidence for this. To test this idea we measured peripheral vision of people with and without hearing loss. We measured “visual crowding: how...
How does the human visual cortex encode perceptual groups?
If you have ever stargazed under an unfamiliar sky (such as after moving from another hemisphere), you have experienced the startling ability of the human visual system to generate patterns from noise. Stars in the night sky are placed essentially at random, yet our...
Object-Knowledge Sharpens Vision
It is widely held that the brain derives object information from features of images.
