Encoding Modality and Spatial Memory Retrieval
Tlauka, Michael; Clark, C. Richard; Liu, Ping; Conway, Marie
Brain and Cognition, v70 n1 p116-122 Jun 2009
This study examined the temporal characteristics of event-related brain electrical activity associated with the processing of spatial memories derived from linguistic and tactile information. Participants learned a map by (1) reading a text description of the map, (2) touching a wooden topological representation of the map (hidden from view), or (3) both. Subsequently, the participants' ability to use their spatial knowledge was tested in a spatial orientation task. Differential patterns of brain activity as a function of encoding modality were found at the very early (preconscious) stages of processing. In contrast, an analysis of behavioral performance revealed no differences between the encoding groups. A model of spatial memory retrieval is presented to account for the findings. (Contains 6 figures and 2 tables.)
