Figure 3

(A) The muscarinic acetylcholine receptor (mAChR) antagonist scopolamine decreased all animals’ choice of HR. When examined separately, scopolamine decreased workers’ HR choice but had no effect on slackers’ choice. (B, C) The drug had no effect on animals’ accuracy or premature responding. (D, E) The mAChR agonist oxotremorine had no effect on animals’ choice or accuracy. (F) Oxotremorine did, however, decrease premature responding for all animals across both trial types.
