Basic Task Description
The CNP "RL" task contains two tasks embedded in one - a probabilistic selection task and a probabilistic reversal learning task. These tasks were designed to assess feedback sensitivity and behavioral flexibility, respectively. Both tasks have been widely used to determine reinforcement learning and behavioral flexibility in healthy and patient populations. The probabilistic selection task, initially designed by Michael Frank, is specifically used to determine participants' tendencies to learn either from positive or negative feedback (e.g., Frank et al., 2004). The probabilistic reversal learning task, originally developed by Trevor Robbins and Robert Rogers (Lawrence et al, 1999; Swainson et al., 2000), examines participants' ability to adapt to changes in learned contingencies.

Task Structure Detail
This is what we had worked on before, but could use updating. We'd like to capture a schema that can handle each of the tasks in the CNP, so please think general when editing -fws
