Apparent Movement of Successively Generated Subjective Figures

摘要: In the present studies a pair of random-dot frames was constructed so that two areas in first frame (f1) were correlated with second (f2). The alternation (an f1--f2 sequence) gave rise to subjective figures. When pairs randomdot sequence and an f3--f4 sequence), each which produced figures different locations, thmeselves alternated, from interacted produce apparent movement. With any one four general kinds displays we constructed, subjects usually perceived only types subjective-figure type movement given display depended primarily upon degree change (across interval between internal structure successively generated Relative intensity differences their backgrounds influenced seen, whereas variations density elements did not. We tentatively propose two-stage model explain figures: stage is assumed generate by means cross-correlation distributions within sequence; on basis inputs stage, generates signals for
