| Outline of Annual Research Achievements |
This research aimed to investigate how attention is guided when directed internally into memory. The first part of this project, titled "Objects in Visual Working Memory are Indexed by a Single Feature" found that attention remains predominantly feature-based process. However, a single feature is given dominance, while access to other features require first going through the primary feature. This research was presented at the Vision Sciences Society in 2022 and is currently undergoing peer review.
The second part of this project, titled "Visual Versus Memory Search: The Role of High Versus Low-Level Features" found that higher-level features guide internally directed attention better than when externally directed, consistent with visual working memory being higher level in nature. This research was presented at the Object Perception Attention and Memory conference in 2022 and is currently in preparation for submission to an academic journal.
A side issue in this project, titled "How does working memory work? Objects but not Boolean maps as the manipulation unit of working memory", was also concluded, investigating not only how attention is used to select items in memory, but also the manipulate them. We found that such manipulation follows the Boolean Map theory of attention, rather than an object-based theory, suggesting that even memory manipulation is feature based. This work is currently undergoing peer review.
