The Influence Of Target Motion Attribution On Representational Momentum

Representational momentum is one of main research hotspots in contemporary psychophysics and cognitive science. Memory for the final position of a target is usually displaced in the direction of target motion,a finding referred to as representational momentum. Researchers think that this displacement implies object’s momentum.However, whether or not attribution of the source of target motion would influence representational momentum in a collision event,which have been always a highly controversial topic.Some people think that representational momentum appears to be attenuated for causally’launched’objects. This is explained by appeal to the visual expectation that a’launched’ object is inert and thus should eventually ceaseits movement after a collision, without a source of self-propulsion. While others suggest that the representational momentum attenuation effect is not a pure measure of causal perception, but rather may reflect lower-level spatiotemporal correlates of only some causal displays. We continue using launching-type event, discussing the influence of attribution of the source of target motion and eye movements on representational momentum from different aspects.(1) The first study examines the relationship between attribution of the source of target motion and representational momentum through manipulating the relative speed and size, and find that attribution of the source of target motion and eye movements joint influence representational momentum:if observer attributes target motion to nontarget, representational momentum appears to be attenuated;if observe think that target motion is self-propelled, representational momentum appears to remain unchanged. The eye movements of observers also contribute to representational momentum.(2) Through manipulating the spatiotemporal relation,the second study examines how does the different collision conditions alter the obersevers’ attribution,which influence the size of representational momentum. We find that observers attribute the source of target motion to the impulse of nontarget in time-space consistency conditions.On the other hand, observers attribute the source of target motion to a source of self-propulsion. in time-space inconsistency conditions.Observers use different eye movements patterns in different collision event.(3) After controlling of the obersevers’ attribution,the third study discusses how does the obersevers use different information available influencing representational momentum through manipulating the information after collision. We find that implied information of dynamics contributes the size of representational momentum. eye movements play an role on on representational momentum in different collision eventsIn conclusion, attribution of the source of target motion caused the representational momentum attenuation effect.Observe have different attribution in different collision conditions,which influence the sizes of representational momentum.Obsever use different information to judge the final position of target.Furthermore,eye movements play an important role on representational momentum.
