Abstract text Numerous investigations demonstrated how even extremely experienced performers in sport can be influenced by various environmental factors, hence perform non-optimally. We selected five hundred incidents of collisions between attacker and stationary defender (offensive foul situations) from games of the Israeli Super League. The incidents were analyzed by three independent groups of three experts (elite basketball referees). The first group decided whether the defender was able to remain standing (i.e., chose voluntarily to fall); the second group was requested to make a referee’s judgment (e.g., offensive foul, defensive foul, technical foul for intentionally falling defender – “flop”); and the third group focused on collisions where the defender remained on his feet, and decided for each incident if an offensive foul was committed. Real game decisions were compared to the expert answers. Environmental information for each incident was assessed. Our findings indicate that players usually tried to deceive the referees by exaggerating the collision and falling on purpose; this resulted in slightly higher percentage for offensive fouls awarded, but overall reduced the effectiveness of the defense. The referees were able to some extent to distinguish between deceptive and non deceptive falls. Based on the sufficient differences between laboratory and game decisions we concluded that certain “environmentally dangerous” calls were avoided by referees.
