Self-initiated encoding facilitates object working memory in schizophrenia: implications for the etiology of working memory deficit.
BACKGROUND Working memory (WM) deficit is present in a majority of patients with schizophrenia but it is unclear which components of WM are impaired. Past studies suggest that encoding may be compromised. One important determinant of encoding is the deployment of selective attention to the target stimulus. In addition, attention and encoding are modulated by motivational factors. In this study,...
متن کاملSpatial patterns and memory for locations.
Rats obtained food from the tops of vertical poles in a 5 x 5 matrix of locations. On each trial, the baited locations formed one of the two possible exemplars of a checkerboard spatial pattern. During training, locations that had been visited earlier in the trial were indicated by a visual cue. Following training, performance with and without the visual cues was compared. Spatial choices were ...
متن کاملDistinct Neural Substrates for Maintaining Locations and Spatial Relations in Working Memory
Previous work has demonstrated a distinction between maintenance of two types of spatial information in working memory (WM): spatial locations and spatial relations. While a body of work has investigated the neural mechanisms of sensory-based information like spatial locations, little is known about how spatial relations are maintained in WM. In two experiments, we used fMRI to investigate the ...
متن کاملThe role of spatial selective attention in working memory for locations: evidence from event-related potentials.
We investigated the hypothesis that the covert focusing of spatial attention mediates the on-line maintenance of location information in spatial working memory. During the delay period of a spatial working-memory task, behaviorally irrelevant probe stimuli were flashed at both memorized and nonmemorized locations. Multichannel recordings of event-related potentials (ERPs) were used to assess vi...
متن کاملCombining Locations from Working Memory and Long-Term Memory into a Common Spatial Image
This research uses a novel integration paradigm to investigate whether target locations read in from long-term memory (LTM) differ from perceptually encoded inputs in spatial working-memory (SWM) with respect to systematic spatial error and/or noise, and whether SWM can simultaneously encompass both of these sources. Our results provide evidence for a composite representation of space in SWM de...
