Amphetamine (AMP) improves true memory for studied words, while THC impairs it, but neither drug significantly changes the tendency to falsely remember nonstudied words compared to placebo. Across participants, the drugs' effects on true memory correlated positively with their effects on false memory, suggesting that encoding processes influenced by these drugs similarly affect both accurate and false recollection. These results come from two within-subjects, double-blind experiments using the Deese/Roediger–McDermott illusion to test recognition memory two days after drug administration.
