Trial overview. (A) Object presentation: 19 stationary white objects are presented. (B) Target indication: A subset of 6 targets are indicated in gray. (C) Track objects: Objects move across the screen bouncing off each other and from the screen borders. (D) Select targets: Participants individually select objects that they think are the targets. (E) First row: Participants receive scores about their individual performances (i.e., “Me” and “Partner”) and the pair's performance (“Team”). Second and third row: In addition to the member's own selections (shown in blue), the partner's selections are also shown (in yellow). Overlapping selections are shown in both colors. (F) Third row: After participants receive information on the partner's selections (and possible overlapping selections), they receive scores about their individual performances and the pair's performance.
