Binocular information acquisition and visual memory.

Binocular information acquisition and visual memory.

Mechanisms underlying the binocular combination of visual information were investigated within the context of a visual information acquisition theory proposed by Loftus, Busey, and their colleagues (e.g., as described by T.A. Busey & G. R. Loftus, 1994). A central assumption of the theory is that of a sensory threshold, which engenders an information loss such that information processing subseq...

Visual Development and the Acquisition of Binocular Disparity Sensitivities

Visual pigments and the acquisition of visual information.

All the information available to the brain for the interpretation of the visual scene comes from the number of photons absorbed by a very limited number of photoreceptor types which are characterized by their spectral sensitivity. In vertebrates there are considerable differences in the spectral absorption of the rods and cones making up the retinal mosaic of different animals and, in some case...

Binocular Summation within the Binocular Visual Field

To study the influence of binocular summation on the threshold values of the central visual field in normal subjects, the authors modified the Octopus 201 by combining it with the space synoptophore. They tested ten normal subjects between 20 and 30 years of age. A space synoptophore was built into the cupola of the Octopus 201 so that the authors could confirm the conditions of binocular visio...

A theory of visual information acquisition and visual memory with special application to intensity-duration trade-offs.

We describe a theory of memory for visual material in which the visual system acts as a linear filter operating on a stimulus to produce a function, a(t), relating some sensory response to t (the time since stimulus onset). Stimulus information is acquired at a rate proportional to the product of the magnitude by which a(t) exceeds some threshold, and the amount of as-yet-unacquired information...
