Example pattern trial of the TEAM task. Partners (e.g., parents and their adolescent children) complete this task while being simultaneously scanned and are told that they are completing the task cooperatively. In each pattern trial, participants are shown a pattern of four arrows twice. Then, they have four seconds to recreate this pattern from memory using a handheld response box. Finally, they are given feedback on their own performance (i.e., whether they entered the pattern correctly) as well as their partner’s. However, the feedback about their partner’s performance is preprogrammed, and in 16% of the trials, participants are told their partner made an error that cost the dyad five dollars.
