Repeated extrinsic rewards following retrieval practice facilitate later memory

This study shows that repeated rewards after retrieval practice improve memory, while low vivid retrieval practice impairs memory.

Mnemonic brain state engagement is diminished in healthy aging

This study finds that older adults show diminished engagement in mnemonic brain states compared to middle-aged adults during memory tasks.

Successful retrieval is its own reward

This study shows that successful memory retrieval is intrinsically rewarding, as positive feedback occurs regardless of task goals.

Top-down task goals induce the retrieval state

The paper investigates how top-down task goals and bottom-up stimulus factors influence retrieval state engagement during memory tasks.

Response-locked theta dissociations reveal potential feedback signal following successful retrieval

The paper examines theta power changes before and after memory responses, finding a dissociation where theta power is higher for correct rejections than hits post-response, suggesting feedback mechanisms in memory retrieval.

Spatiotemporal dynamics of memory encoding and memory retrieval states

The paper identifies spatiotemporal dynamics of memory encoding and retrieval states using microstate analysis of EEG data from a mnemonic task.

Spatiotemporal context modulates encoding and retrieval of overlapping events

The paper investigates how temporal overlap between events affects memory interference and retrieval, showing that greater overlap impairs memory for past events when encoding present events.

Targeted stimulation of human orbitofrontal networks disrupts outcome-guided behavior

This study uses cTBS to disrupt human OFC network activity and shows impaired outcome-guided behavior after reward devaluation.
