Abstract

The present four experiments examined the effects of pointing movements towards the target locations in a modified free recall task. Three factors were manipulated: the order of the move/no-move trials (blocked or mixed), the type of stimuli presentation (simultaneous or sequential) and the size of the to-be-recalled configurations (7-9 and 5-7 items). Results showed that pointing significantly decreased visuospatial performance both with a mixed and a blocked design. However, in the blocked condition the interference effect of pointing was load-dependent (being inversely related to array size) and occurred only when participants pointed to all stimuli in the first block. Post hoc analyses supported the conclusion that pointing movements interfered with the on-line development of appropriate retrieval strategies, like parsing the configurations into smaller chunks or creating global visual images.
