Eye contact established by a human partner has been shown to affect various cognitive processes of the receiver. However, little is known about humans’ responses eye humanoid robot. Here, we aimed at examining oscillatory brain response with (or lack thereof) was embedded in gaze cueing task and preceded phase gaze-related attentional orienting. In addition effect on recipient, also tested its impact effects. Results showed that participants rated as more engaging responded higher desynchronization alpha-band activity left fronto-central central electrode clusters when robot them, compared no condition. did not modulate The results are interpreted terms functional roles involved alpha rhythms (potentially interpretable mu rhythm), including joint attention engagement social interaction.
