Evidence for a reactionary account of retrieval state initiation.

Han S, Long NM · 2025 · Imaging neuroscience (Cambridge, Mass.)

Engagement of the retrieval state (or mode) is theorized to be a precursor to successful retrieval, but precisely when the retrieval state is engaged is unclear. Our aim in the present study is to determine the time course of retrieval…
