This study aimed to investigate what roles dopamine plays in the retrieval of different types of memory. Healthy older participants learned several memory tasks on one day, and then came back in the next day to be tested on them. On day 2 they received either a placebo or a drug (Levodopa, a dopamine precursor) and were tested 1 hour later. Participants completed both conditions (drug and placebo) in a randomised order, fully double-blinded.
This dataset is the digit span data from days 2 and 4 (drug and placebo days) for all participants who completed both days of testing, along with some demographic and questionnaire data.
