Knoblich and Jordan (2003) investigated the mechanisms underlying such anticipatory coordination, using a simple computer game that posed coordination challenges similar to rowing a canoe together. The main question was whether receiving an unambiguous signal about the timing of the other person’s action would allow two individuals to achieve the same degree of coordination as a single individual playing the game alone. Although, initially, group performance was much worse than individual performance, groups who received timing feedback gradually became as effective as individuals in coordinating the two actions. Groups that were only given information about the joint outcome of their actions never reached the level of individual performance. Feedback led partners to develop a model of each other, allowing them to anticipate each other’s action timing.
