Abstract:
The visual presentation of real, apparent or implied object motion is often accompanied by systematic errors in localization. In this talk, I will concentrate on one form of error -- representational momentum -- in which observers systematically misremember a stopping point as being further forward in the direction of motion or change. I will begin by demonstrating the wide range of situations in which this error can be obtained, examine links with other forms of mislocalization, and discuss the potential benefits of being able to anticipate object motion. Next, I will describe a number of situations in which anticipation does not occur, notably with complex, non-rigid changes, such as facial motion. Finally, I will present some recent work in which we have been using VR to explore anticipation effects in grasping.
