Illusory jitter in a static stimulus surrounded by a synchronously flickering pattern.

abstract：:We compared the mechanisms responsible for orientation discrimination of stimuli defined by luminance and red/green isoluminant contrast. A four-alternative forced-choice (4-AFC) paradigm was used to determine thresholds for discriminating 1 cpd sinewave gratings differing in orientation, contrast, or both. When measu...

abstract：:In typical binocular rivalry demonstrations, disparate images presented in corresponding locations to the two eyes are found to alternate perceptually over time. Alternation in perception can occur even if the images presented to the two eyes do not overlap, if they are sufficiently close in space. This implies a spat...

To examine this, the shape of the eye-lens during accommodation or its relaxation is analysed with special reference to age-related changes.
