Selective Attention and Memory: The Unforgettable Duo!

Published on September 8, 2023

Imagine attention as a bouncer guarding the entrance to your brain’s VIP section known as working memory. But hold on! Recent research has unveiled attribute amnesia, where the bouncer allows information to pass through the gates only to forget it moments later. This astonishing phenomenon suggests that attention doesn’t always ensure information reaches working memory. Enter memory reselection, a captivating concept that proposes a second round of selection among the attended information. It challenges traditional thinking about the connection between attention and working memory, painting a picture of these processes as separate entities. By expanding our understanding, scientists can refine their models of attention and memory, leading to exciting new possibilities in cognitive sciences!

Attention has been regarded as the ‘gatekeeper’ controlling what information gets selected into working memory. However, a new perspective has emerged with the discovery of attribute amnesia, a phenomenon revealing that people are frequently unable to report information they have just attended to moments ago. This report failure is thought to stem from a lack of consolidating the attended information into working memory, indicating a dissociation between attention and working memory. Building on these findings, a new concept called memory reselection is proposed to describe a secondary round of selection among the attended information. These discoveries challenge the conventional view of how attention and working memory are related and shed new light onto modeling attention and memory as dissociable processes.
