Abstract:
The planning/control model of action assumes that grasping is sensitive to the context of an object only in early
stages of the movement (planning), but not in later stages
(control). In consequence, the effects of context-induced
illusions (as the Ebbinghaus/Titchener illusion) should
decrement during a grasping movement. Here, we tested this
claim by reanalysing a large data set (N=26) on grasping in
the Ebbinghaus illusion. Contrary to the predictions of the
planning/control model, we found that the effects of the
illusion did not decrease over time. Instead, the illusion
effects stayed remarkably constant.
