Investigating how reward retroactively improves memory for associations and items: A registered report.

Given we cannot remember all our experiences, it seems intuitive that we should prioritize events of consequence, like those that lead to a reward. However, rewards have had inconsistent effects on people's memory for preceding neutral experiences in experiments, raising questions as to whether our minds are equipped to remember adaptively. Here, we used online testing in a registered report to investigate whether rewards tend to retroactively enhance certain types of memories. Consistent with prior research and theories involving how dopamine modulates the hippocampus, we hypothesized that re
