This study examined the effect of the amount of past experience upon the binocular rivalry between one of portraits of male students (F-figure) and a geometrical figure (G-figure). Prior to the observation of binocular rivalry, F-figures were presented with different frequencies in the paradigm of pairedassociate learning between F-figures and the family names randomly assigned to them. The results showed the tendency that the relative dominance of F-figure over the other in binocular rivalry systematically increases as the frequency of previous presentation (PF) of the F-figures increases.
