Fig 1. Meth effects on recognition.

Effects of METH on mean (+/- SEM) recognition accuracy as a function of self-reported sleep quality in the encoding group. Adequate sleep group consists of participants who reported sleeping at least six hours the night after receiving the 20 mg dose (n = 14); poor sleep group consists of participants who reported sleeping less than six hours the night after receiving the 20 mg dose (n = 15). 1 = perfect discrimination; 0 = no discrimination (chance responding). *p<.05 compared to placebo
