Joint action in Human Robot Interaction, event related potential (ERP) perspective in a Go/No-go task
How do we perceive a robot in a joint action? Turing test?
We already know that when couple of individuals or more get together and engage in a joint action, they alter their neuro-cognitive processes responsible of such actions. Alternatively, we wanted to investigate in an experiment whether a robot would have similar effect on a human when the two engage in a similar task. We recorded electric brain activities using event related potential (ERP) technique of Electroencephalography (EEG) as participants were doing the experiment, we did find some early evidence that indeed, a human doing a task with a robot shows neural oscillations that are different from when he is doing the task by himself but more closely resembling that when engaging with another human.
Method
13 Healthy subjects completed a 3 part Go/No-go ERP experiment using a Biosemi EEG system where we observed P300 component under various conditions:
1-Human-Robot (HR), human and robot subjects participate in a joint task.
2- Human-Human (HH), two human subjects complete task.
3- Human-Only (HO), human subject running same experiment alone;
1-Human-Robot (HR), human and robot subjects participate in a joint task.
2- Human-Human (HH), two human subjects complete task.
3- Human-Only (HO), human subject running same experiment alone;
Results
Event-related brain dynamic of P300 for all 3 tasks:
Human Only (HO) / Human-human (HH) / Human-robot (HR)
Human Only (HO) / Human-human (HH) / Human-robot (HR)
