Spatial frequency adaptation: Threshold elevation and perceived contrast

We have measured the spread of contrast adaptation across the dimension of spatial frequency. Threshold elevation was tightly tuned to the adapting spatial frequency but became much broader as test contrast was increased. This means that, for a given test frequency, there are some frequencies which do not raise threshold but do result in a loss of perceived contrast. The contrast dependence, re...

Contrast threshold elevation following continuous and interrupted adaptation.

Contrast thresholds for a 6 c/deg sinewave grating were measured following continuous and interrupted adaptation of 10 min duration to a high-contrast (0.6) sinewave grating of the same spatial frequency. Interrupted adaptation was administered as five 2-min segments, and the interadaptation interval (IAI) was varied from 10 to 180 sec. The results indicate that adaptation to spatial contrast c...

Spatial-frequency bandwidth of perceived contrast

The aim of this study was to investigate the spatial-frequency bandwidth of perceived suprathreshold contrast. It has been shown that for grating stimuli contrast detection thresholds depend on spatial frequency, grating area and the number of orientation components. However, suprathreshold contrast perception exhibits contrast constancy, i.e. suprathreshold contrast matches are independent of ...

Spatial frequency adaptation can enhance contrast sensitivity.

A~~ct-Adaptation to a high-contr~t sinusoid& ium~nan~ grating produces a temporary, bandlimited loss in sensitivity centered around the adaptation frequency. The decrease appears to be both narrower and more symmetrical than earlier reports suggest. The effect falls to zero by f f 1 octave and is not reliably present from f f 1 octave to f k 2 octaves. Enhancement of contrast sensitivity occurs...

A labeled lines explanation of the perceived spatial frequency of moderate-, near-threshold- and zero-contrast spatial patterns

We tested the predictions of a multiple-channels model about the appearance of spatial patterns. Specifically we tested how encoding the perceived spatial frequency of a near-threshold pattern compared with encoding of a zero-contrast or moderate-contrast pattern. For example, the model predicts that the mean perceived spatial frequency of a near-threshold pattern is a weighted average of the r...
