Orientation-specific configuration based representations in spatial working memory

Spatial Memory and Spatial Orientation

Navigating through a remembered space depends critically on the ability to stay oriented with respect to the remembered environment and to reorient after becoming lost. This chapter describes the roles of long-term spatial memory, sensorimotor spatial memory, and path integration in determining spatial orientation. Experiments presented here highlight the reference direction structure of long-t...

No functional role of attention-based rehearsal in maintenance of spatial working memory representations.

The present study systematically examined the role of attention in maintenance of spatial representations in working memory as proposed by the attention-based rehearsal hypothesis [Awh, E., Jonides, J., & Reuter-Lorenz, P. A. (1998). Rehearsal in spatial working memory. Journal of Experimental Psychology--Human Perception and Performance, 24(3), 780-790]. Three main issues were examined. First,...

Modality-specific control processes in verbal versus spatial working memory.

Over the past decade, neuroimaging and electrophysiological studies of working memory (WM) have made progress in distinguishing the neural substrates of central executive (CE) functions from substrates of temporary storage subsystems. However, the degree to which CE-related processes and their substrates may be further fractionated is less clear. The present study measured event-related potenti...

Rehearsal in spatial working memory.

This article reports 3 experiments that tested a hypothesis regarding the nature of rehearsal in spatial working memory, one in which discrete shifts of spatial selective attention mediate the maintenance of location-specific representations. Experiment 1 demonstrated increases in visual processing efficiency for locations held in working memory, which suggested that attention was oriented towa...
