Experiments 2—4, seated opposite. Panel A: Experiment 2: shared target, seated opposite, same hands. Black square is the target; white square is the obstacle. This example shows a No — O—No trial. Panel B: Experiment 3: shared target, seated opposite, mirrored hands. This example shows an O —O —No trial. Panel C: Experiment 4: shared obstacle, seated opposite, same hands. This example shows an O —O —No trial. Experiments 2 and 3 share the same layout and differ only in hand use. Experiment 4 uses a narrower table, allowing participants to be close enough to share the same obstacle and to reach into each other's peripersonal space.
