| Q1 | I did everything I could to win the game | 4.5 ± 1.3** | 4.5 ± 1.3** | 4.3 ± 1.0** | 4.0 ± 1.0** | n.s. | n.s. | n.s. |
| Q2 | I only played the chips after choosing them first | 4.2 ± 1.3* | 4.2 ± 1.1* | 3.8 ± 1.0* | 4.2 ± 1.1** | n.s. | n.s. | n.s. |
| Q3 | I took my opponent's last moves into account before deciding which chip to play next (M) | 3.9 ± 1.7 | 3.7 ± 1.6 | 4.2 ± 0.7** | 3.8 ± 1.0* | n.s. | F = 5.7, p = 0.02 | n.s. |

* p < 0.05, ** p < 0.005 for one-sample t-test, testing difference from the middle score of 3. G = Group (ASD, TD); OT = Opponent Type (Human, Computer); ME = Main effect; M = Mentalizing question; OG = Overt Gains; RG = Relative Gains; OL = Overt Losses; RL = Relative Losses.
