|I succeeded in replicating the effect of mask temporal frequency on dominance durations in CFS as reported in the supplementary materials of Tsuchiya & Koch (2005).
We tested a total of 4 unique participants.
Participants tracked the dominance of the CFS mask versus a Gabor patch (6°; 1.2 c/deg spatial frequency; 45° orientation, full contrast) in 12 different temporal frequency conditions (1,2,3,4,5,6,10,12,15,20,30, and 60 Hz).
Each session consisted of 1 minute trials in which participants had to continuously indicate their percept. Participants had to take a 1 minute break after every trial. Four sessions were run on each participant.
