The apparent size of the disks was manipulated by a visual illusion. Of the two aspects of the action which depend on the objects size, only one was affected by the illusion. We conclude that different aspects of an action are controlled independently, instead of being co-ordinated on the basis of one perceptual variable. date: 1996 date_type: published publication: Studies in ecological psycholgy: Proceedings of the Fourth European Workshop on Ecological Psychology publisher: Delftse Universitaire Pers, Delft pagerange: 147-149 refereed: FALSE citation: Smeets, Jeroen B.J and Brenner, Eli (1996) Multiple specification of an object's size for picking it up.
