Maintenance of item and order information in verbal working memory
2017
International audience; Although verbal recall of item and order information is well-researched in short-term memory paradigms, there is relatively little research concerning item and order recall from working memory. The following study examined whether manipulating the opportunity for attentional refreshing and articulatory rehearsal in a complex span task differently affected the recall of item- and order-specific information of the memoranda. Five experiments varied the opportunity for articulatory rehearsal and attentional refreshing in a complex span task, but the type of recall was manipulated between experiments (item and order, order only, and item only recall). The results showed …
Temporal stability and representational distinctiveness: Key functions of orthographic working memory
2011
A primary goal of working memory research has been to understand the mechanisms that permit working memory systems to effectively maintain the identity and order of the elements held in memory for sufficient time as to allow for their selection and transfer to subsequent processing stages. Based on the performance of two individuals with acquired dysgraphia affecting orthographic working memory (WM; the graphemic buffer), we present evidence of two distinct and dissociable functions of orthographic WM. One function is responsible for maintaining the temporal stability of letters held in orthographic WM, while the other is responsible for maintaining their representational distinctiveness. T…
Serial position effects in dementia of the Alzheimer type.
1998
<b>Background: </b>The aim of the present study was to analyse serial position effects for immediate and delayed free recall in patients with dementia of the Alzheimer type and controls. <b>Experiment 1:</b> 44 patients with dementia of the Alzheimer-type and 24 non-demented controls were asked for immediate and delayed free recall of 12 schematic drawings of common objects presented at the rate of 10 s/picture. Steep primacy effects were obtained at all delays in controls. By contrast, primacy effects were significantly impaired in patients with dementia at all delays of recall. Small immediate and delayed recall recency effects were found in both, patients and cont…
