The perception of motion serves several ecologically-valid purposes such as aiding in navigation or image segmentation (figure segmentation) through space and time. The purpose of the present work is to evaluate image representation from motion cues across space-time in humans. Random-dot kinematograms an psychophysical methods are used to assess motion perception under various conditions. The first article explores motion integration across large expanses of space (and across central and peripheral vision) and for two behavioural conditions. The second assesses the effect of spatio-temporal parameters on motion integration or segregation. Generally, signals are integrated when shown simultaneously (for two spatial positions) or in consecutive order, whereas differences are enhanced (segmentation) when a novel temporal gap is present between motion sequences. Additional effects of spatial configuration are apparent (adjacent vs spatially separated regions), and contextual constraints may influence results. Implications for cooperative and competitive networks involved in motion perception, and for surface representation are discussed.
