My role consisted of aiding two projects looking at confidence and instruction in reversal learning and reward and task switching. For these experiments, I was in charge of recruiting participants, carrying out the experiment and at times analysing bits of the datasets. For the reward and task switching we were particularly looking at how reinforcement learning effected task switching paradigms and whether positive reward prediction errors create stronger learning effects than negative reward prediction errors. For the confidence and instruction in reversal learning experiment we were interested in how confidence is effected by feedback and whether positive or negative feedback could affect confidence in judgment on preceding trials. I also assisted with recruiting participants for an fMRI experiment that used a similar experimental paradigm to the reward and task switching.
