Following adaptation to a target imaged with a certain disparity the apparent depth of targets
imaged with nearby disparities is altered. With simple stimuli (single lines) the maximum …

During adaptation to a high contrast grating it gradually seems to fade. A lower-contrast test
grating appearing directly after the adapting pattern appears reduced in apparent contrast …

1. Human visual selectivity for direction of movement was determined using a subthreshold
summation technique. 2. The threshold contrast for detecting a drifting sinusoidal grating …

1. The detectability of contrast modulation (M) of sinusoidal gratings was explored at the rate
of 8 Hz. The luminance profile of a contrast modulated sinusoidal grating is L= L (1+ C cos 2 …

1. Adaptation to a high‐contrast sine‐wave grating has been shown previously by
Blakemore & Campbell (1969) to raise the modulation required to detect a low‐contrast …

1. Inspection of a high‐contrast adapting grating produces two visual after‐effects:(a) the
contrast threshold is raised for test gratings of similar spatial frequency to that of the adapting …

The fundamental advantage of measuring the contrast sensitivity of the eye using sinusoidal
gratings is that it gives a more complete description of its functional range. Such …

The responses of neurones in the cat's visual cortex are very variable in amplitude. Thus,
although the average response amplitude of a single neurone depends closely upon the …
