Asynchrony distribution in simulated and real birds.
The relative frequency distribution of asynchrony in the MC, CI, MI and SR simulations and two real subjects (Male B and Female D) under the 1,200-ms-IOI condition is shown (bin width, 60 ms). The figure shows that the real birds directed their pecks at a certain point and the phase relationship remained constant although they could have accomplished the tasks using the MC, CI and MI strategies.
