Table 2 Mean (standard deviation in parathesis) performance for the single-cue probabilistic learning task and the multi-cue probabilistic learning task as well as mean learning rate (standard deviation in parenthesis) for the reinforcement learning task by group. Asterisks indicate above chance performance (50%) for the single-cue and multi-cue learning tasks based on one-sample t-tests (this was not conducted for the reinforcement learning task as learning rate cannot be determined by chance)
