Figure 5. Selected frames from the test event used in Experiment 3.

The event started with the fair and unfair distributors visible on the lower part of the screen. Above each of them there was a green cup. Shortly after the beginning of the trial an orange circle entered the scene from above and performing a neutral action with the cup that was either near the fair or the unfair agent. The action consisted in pushing the cup with a brown rod so that its final position was about 3 cm either to the right or to the left of its initial position, but not moving it closer or farther away from the donor.
