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 errorrepresentational
momentumin which observers systematically misremember a stopping point as being further
forward in the direction of motion or change. While representational momentum has been
demonstrated using a wide variety of stimuli, in this talk I will focus specically on the perception
and production of human actions. I will begin by reviewing a number of studies that
have examined our ability to anticipate simple human actions, such as walking. I will then
discuss recent work in our lab that has directly compared anticipation in visual perception with
the production of grasping movements. Finally, I will discuss an ongoing project that explores
how prior experience in manipulating physical objects that differ in weight affects subsequent
visual anticipation when those objects are seen moving.
