[The effect of form information and presentation order of stimuli on stroboscopic motion]

The likelihood of stroboscopic motion between different contour combinations was obtained under temporal conditions (duration, ISIs). Three kinds of contour figures were prepared; the real, the subjective and the control. Two stimulus figures for such combinations were chosen from these three; one as the first stimulus and the other as the second. The result was that the likelihood of seeing motion was reduced, when the contour figure of more form information was used as the first stimulus and that of less form information as the second than when they were in the reverse order. This was considered as the effect of order of stimulus presentation.
