人形机器人领域的快速进展为研究和提高社交缺陷患者的社交能力提供了巨大的可能性，但在精神分裂症方面尚未得到探索。在这项研究中，我们研究了人形机器人在人机交互过程中引起的社会反馈对运动协调的影响。 22 名精神分裂症患者和 22 名匹配的健康对照者与 iCub 人形机器人一起接受了协作运动同步任务。结果显示，与非社会积极反馈相比，积极社会反馈对对照参与者的运动协调有促进作用。这种促进作用在精神分裂症患者中并不存在，他们的社会运动协调在社会和非社会反馈条件下同样受到损害。此外，患者的认知灵活性障碍和抗精神病药物剂量与患者与 iCub 同步手部动作的能力呈负相关。总体而言，我们的研究结果表明，患者在利用人形机器人引发的面部社交线索来调节人机交互过程中的运动协调方面存在明显困难，部分原因是认知缺陷和药物治疗。这项研究为理解这种精神障碍的社会缺陷开辟了新的视角。
Rapid progress in the area of humanoid robots offers tremendous possibilities for investigating and improving social competences in people with social deficits, but remains yet unexplored in schizophrenia. In this study, we examined the influence of social feedbacks elicited by a humanoid robot on motor coordination during a human-robot interaction. Twenty-two schizophrenia patients and twenty-two matched healthy controls underwent a collaborative motor synchrony task with the iCub humanoid robot. Results revealed that positive social feedback had a facilitatory effect on motor coordination in the control participants compared to non-social positive feedback. This facilitatory effect was not present in schizophrenia patients, whose social-motor coordination was similarly impaired in social and non-social feedback conditions. Furthermore, patients’ cognitive flexibility impairment and antipsychotic dosing were negatively correlated with patients’ ability to synchronize hand movements with iCub. Overall, our findings reveal that patients have marked difficulties to exploit facial social cues elicited by a humanoid robot to modulate their motor coordination during human-robot interaction, partly accounted for by cognitive deficits and medication. This study opens new perspectives for comprehension of social deficits in this mental disorder.
