Neural Predictors of Subsequent Long-Term Memory After (De)prioritization in Working Memory

Presenter: Frieda Born

Which factors determine how well information held in working memory (WM) can later be remembered from long-term memory (LTM)? Prior behavioral work (presented at CCN 2024) from our lab suggests that active WM retrieval (WM-”testing”), particularly when retrieving information that has been deprioritized in WM, can enhance subsequent LTM performance; similar to the well-known “testing-effect” in LTM research. However, the neural mechanisms underlying these effects remain unknown. Here, we used fMRI to study which neural signatures of WM maintenance and/or retrieval predict later LTM performance, so-called "subsequent memory effects" (SMEs). Using a dual-retro-cue paradigm to manipulate attentional priority in WM, we replicate key behavioral effects from our prior work and address the underlying neural mechanisms in ongoing fMRI analysis.
