Motion organization in "stop action" sequences

Abstract.— Do the contents of our successive glances combine by virtue of motion segregation (Johansson) effects? Some explanations of the effects (for example, that they result from uncompensated pursuit eye movements, or that they occur only with continuous stimulus movement) would oppose that proposal. The effects can be obtained with discontinuous stimulus displacements (500 msec jumps), even with a fixation point and visible surroundings. The proposal that glances combine as a result of motion segregation remains viable, therefore, but segregation effects themselves may need reformulation as relational schemas.
