After helping a robot, people responded faster near its robotic hand
Thirty people helped a robot cut soap before an attention task. Among 22 others who did not collaborate beforehand, the pattern did not appear.

The key idea
After collaborating with a robot, visual attention shifted toward its hand. Merely seeing that hand without collaborating did not produce the effect.
The study, in plain language
Sharing a task requires coordinating with another’s movements, whether the other is a person or a robot. In a lab, some people helped a humanoid robot named iCub cut a bar of soap and then completed a quick visual attention task.
After collaborating, they responded faster to cues near the robot’s hand. This pattern did not appear in the group that had not shared the task beforehand. The participant’s own hand, by contrast, showed the expected effect of faster responses near it.
Among those who collaborated, the effect was greater when the robot’s hand had moved more and come closer to the space near the participant. The change thus tracked a specific feature of the collaboration: where the hand had moved.
What they found
- After collaboration, visual responses were faster near the robot’s hand.
- In the group that had not collaborated, the mere presence of the robotic hand did not show this pattern.
- Among collaborators, the effect was greater when the robot’s hand had moved more and come closer to the participant.
Something to think about
Where do you look when sharing a task with someone, or something? In the experiment, those who collaborated with the robot directed more attention toward its hand.
How they studied it
A lab experiment with 52 people: 30 helped a robot cut a bar of soap and then completed a visual attention task. The other 22 did the task without having collaborated with the robot.
What the study cannot show
- The robot had preprogrammed, nonadaptive behavior; there was one collaborative task and one humanoid-looking robot; the control group was small; some associations were estimated from 27 cases and do not by themselves establish the proposed bodily mechanism.
- That collaborating with robots improves general attention, that any robot produces the same effect, that the change lasts outside the lab, or that interaction is necessarily beneficial in other tasks.
