Abstract : Previous studies of saccadic suppression do not rule out the possibility that the phenomenon may be affected by, or produced by, shifts of the Os' criteria for reporting a flash. The present study, using a presumably criterion-free measure (d'), demonstrates a decrease in visual sensitivity beginning as much as 150-200 msec prior to a voluntary saccade. It is suggested that criterion-free measures of visual sensitivity be used in future studies of the saccadic suppression. (Author)
