Graphic showing the Cyberball game as it appeared to participants. When participants received the ball in their ‘hand’ (visible on the bottom of the screen) during the inclusion portion of the game, they indicated the recipient of their next ball toss (i.e., the player on the right or left) using a button-box. During the exclusion portion of the game, the other players (i.e., ‘Danny’ and ‘Erika’) threw the ball back and forth to each other, and it was never thrown to the participant's ‘hand’.
