Associative learning changes multivariate neural signatures of visual working memory

Talk presentation by William Ngiam at VSS 2024 on how training subjects to learn color pairs and color triplets leads to changes in multivariate neural signatures of visual working memory load. We find there is a reduction in working memory load following associative learning, and the introduction of an additional signal that we speculate is the involvement of long-term memory.
Spatiotemporal processing drives contralateral delay activity in a dual working memory and attentional tracking task

Talk presentation by Piotr Styrkowiec at VSS 2024 on our novel attentional tracking and working memory task – a hybrid of multiple-object tracking and multiple-identity tracking. We look at the contralateral delay activity, an event-related potential component known to track visual working memory load during the task, and find that it seems to track the number of discs to remember rather than the number of colors that need to be remembered.

A conference poster presented by William Ngiam at the Psychonomics conference in 2019, showing benefits of statistical learning required explicit awareness of the statistical regularities, suggesting a long-term memory account for the benefit.
