Gain measures for d’ and RT (ms) in Experiment 1 for self bias (black bars) and Experiment 2 for reward bias (gray bars). For the self bias experiment ‘mid’ and ‘low’ were defined as the Friend and Stranger association conditions, respectively. For the reward bias experiment, ‘mid’ and ‘low’ were defined as the £6 and £2 association conditions, respectively. Data presented include all participants (A), or are divided into middle tone (MT) groups: MT Self and MT £18 (B), MT Friend and MT £6 (C), and MT Stranger and MT £2 (D).
