Previous studies had examined the effect of continuous flash suppression (CFS) on static motion aftereffects (sMAE) only when the spatial frequency of the adaptation and test stimuli differed significantly, although sMAE are observed at maximum level when the spatial frequency of the adaptation and test stimuli are the same. The aim of this study was to investigate whether CFS suppresses spatial frequency-selective adaptation to motion stimuli by matching the spatial frequency of the adaptation and test stimuli at several spatial frequencies. It was examined whether sMAE occurred when the adaptation motion was invisible to the observer under CFS. Results showed that sMAE decreased under CFS when the spatial frequencies of the adaptation and test stimuli were the same at any spatial frequency, but the degree of decrease depended on the spatial frequency. This suggests that the suppression of CFS varies with spatial frequency.
