Recognition memory. (A) d′ measure of sensitivity and (B) response bias for 30-min and 24-hr delayed tests (SEM bars). Healthy participants show no decrease in d′ across the delay whereas patients do (F(1, 14) = 14.089, p = .002). Response bias has a significant interaction of Day 1 medication state and delay (F(1, 14) = 15.083, p = .002), with patients on dopamine on Day 1 (blue lines) showing a decrease in response bias over 24 hr (more “yes” responses) and patients off dopamine during learning (red lines) and healthy participants showing an increase in response bias (more “no” responses) irrespective of Day 2 medication (solid/dashed lines).
