Description
A great deal of research has been conducted to investigate the relationship between attention and working memory, in particular how information in working memory can be maintained as the focus of attention (FOA) when necessary. Experiments using sequential visual working memory tasks where certain stimuli are prioritised reveal that prioritisation enhances retention of prioritised items and decreases the recency effect typically found in sequential tasks (e.g., Hitch et al., 2018). Results are interpreted as emerging from an "attentional refreshing" process that maintains items in the FoA to hinder the intrusion of new perceptual information. I present an ACT-R model of this process that provides a detailed, mechanistic account of the human recall data from three experiments conducted by Hitch et al. (2018). The model provides a close fit to the human data and accounts for the improved recall of prioritised stimuli and the reduction of the recency effect in terms of a refreshing mechanism for prioritised stimuli and the subsequent availability of stimulus representations for recall from declarative memory at the time of test.| Period | 23 Jul 2024 |
