Cyclofuslon and stereopsis

Stereopsis

When she becomes dominant her body changes so that she becomes physiologically and morphologically distinct from other non-reproductive female ‘workers’, even her bone structure changes. Mole-rats were thought to be the only mammal to do this, but it has since been discovered that female meerkats also develop elongated vertebra when they become dominant breeders. As well as reproductives, there...

Stereopsis and binocular rivalry.

Stereopsis and binocular rivalry appear to be incompatible. Rivalry involves suppression of input from one eye at each location in space and time, whereas Stereopsis requires the combination of information from both eyes to yield a sensation of depth. This article presents a theory of the relationship of these phenomena. Evidence from previous work and from experiments reported here shows that ...

Torsion and stereopsis.

The perceptual correlates of sensory cyclofusion have received little attention. However, they are easily elicited by asking patients with torsion about perceived slant of the visual world, and by watching how they hold the Titmus or Randot book. Sensory cyclofusion induces two types of perceptual aberrations. First, it rotates the plane of maximal stereoscopic volume in the pitch plane. As suc...

Stereopsis and aging

Three experiments investigated whether and to what extent increases in age affect the functionality of stereopsis. The observers' ages ranged from 18 to 83 years. The overall goal was to challenge the older stereoscopic visual system by utilizing high magnitudes of binocular disparity, ambiguous binocular disparity [cf., Julesz, B., & Chang, J. (1976). Interaction between pools of binocular dis...
