Gabor: Detection of a 2 cycle/window Gabor temporal modulation
Description
The data record the observations of one observer performing a Yes/No detection task. The signal was a temporal luminance modulation of a Gaussian spatial profile ($\sigma$ = 2.5 deg) on a CRT screen. The temporal modulation followed a Gabor function with an envelope of $\sigma$ = 160 ms and duration of 4$\sigma$. The carrier was in sine-phase and of frequency 2 cycles/window width. On each trial random uniform luminance modulations were presented, and on half of the trials, the signal was added in. The data represent 16 sessions of 224 trials each.source
