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...
متن کاملControl and Maintenance Processes in Working Memory: Neuropsychological Investigations
The aim of this thesis was to investigate working memory by investigating performance on an updating task devised to pose variable demands on maintenance and control processes. The task required participants to recall information that was “relevant” according to a given criterion, at the same time inhibiting information that was not relevant to that criterion. Performance on this task was inves...
متن کاملBrain Oscillatory Signatures of Working Memory Control Processes
Memory consists of various individual processes which form a dynamic system co-ordinated by central (executive) functions. The episodic buffer as direct interface between episodic long-term memory (LTM) and working memory (WM) is fairly well studied but such direct interaction is less clear in semantic LTM. Here, we designed a verbal delayed-match-to-sample task specifically to differentiate be...
متن کاملTwo dissociable updating processes in working memory.
The authors show that the updating of working memory (WM) representations is carried out by the cooperative act of 2 dissociable reaction time (RT) components: a global updating process that provides stability by shielding WM contents against interference and a local process that provides flexibility. Participants kept track of 1-3 items (digits or Gibson figures). In each trial, the items eith...
متن کاملValue Conditioning Modulates Visual Working Memory Processes
Learning allows the value of motivationally salient events to become associated with stimuli that predict those events. Here, we asked whether value associations could facilitate visual working memory (WM), and whether such effects would be valence dependent. Our experiment was specifically designed to isolate value-based effects on WM from value-based effects on selective attention that might ...
