Recent data have shown that spatial-frequency adaptation has little effect on spatial-
frequency discrimination at the adapting frequency, but there is a substantial elevation of …

We found that inspecting a sine-wave grating elevated threshold for spatial-frequency
discrimination as it does for contrast detection, but discrimination threshold was maximally …

Previous studies have shown that adapting to a complex grating may produce little rise in
the contrast threshold of a test grating whose spatial frequency matches one of the higher …

Recent data from several laboratories have shown that spatial-frequency discrimination is
not a smooth function of frequency but rather exhibits alternate peaks and troughs. A model …

The relationship between the ability to detect a low-contrast grating and to identify its spatial
frequency or orientation was examined at eccentricities ranging from 0 to 17.5 deg. The form …

Interactions between size and orientation-specific mechanisms in the human visual system
were investigated using a sequential adaptation technique. Subjects adapted to a vertical …

The threshold elevation for a sinusoidal grating of 13.3 c/deg is significantly less for
adaptation to a sum of 10.7 and 8 c/deg or 13.3 and 8 c/deg than for adaptation to 10.7 or …

Aftereffects of spatially localized grating adaptation were measured for different locations of
the adaptation grating relative to test grating. When the adaptation grating was located on or …

Previous work showed that adapting to low spatial frequency gratings (below 1.5
cycles/degree) may cause maximal spatial adaptation at a significantly higher spatial …

A new phenomenon is reported whereby an after-effect of adaptation to unidimensional
sinusoidal gratings, the spatial frequency shift, can be obtained at test orientations which are …
