ABSTRACT

Leading another person’s gaze to establish joint attention facilitates social interaction. Previously it was found that we look back at agents who engage in joint attention quicker than at agents who display this behaviour less frequently. This paper serves to fill in two remaining knowledge gaps. Firstly, we examined whether this looking-back behaviour is replicated by a manual response. In an online task, participants selected one of two objects. One robot identity on the screen followed the selection most of the time, whilst the other looked at the other object most of the time. Participants clicked back on the following robot quicker when it looked at the same object relative to when it did not. We found no such difference for the unfollowing robot. Secondly, we examined how individual differences in autistic traits and adopting the intentional stance affected participants’ behaviour over time. The results showed that autistic traits influenced participants’ motor responses over time across conditions, whereas this response was only sensitive to the intentional stance for the unfollowing robot. Our results indicate that there is a potential overlap between evoked gaze behaviour and manual actions. However, individual differences may not fully predicate reflexive social behaviour.

摘要

引导另一个人的目光以建立共同注意力有助于社交互动。以前发现，我们回顾那些参与联合注意力的代理人比不那么频繁地表现这种行为的代理人要快。本文旨在填补两个剩余的知识空白。首先，我们检查了这种回顾行为是否被手动响应复制。在一项在线任务中，参与者选择了两个对象之一。屏幕上的一个机器人身份大部分时间都跟随选择，而另一个机器人身份大部分时间都在看着另一个对象。当机器人看着相同的物体时，参与者会更快地点击下一个机器人。我们发现未跟随机器人没有这种差异。其次，我们研究了自闭症特征的个体差异和采取有意的立场如何随着时间的推移影响参与者的行为。结果表明，随着时间的推移，自闭症特征会影响参与者的运动反应，而这种反应只对不跟随机器人的故意姿态敏感。我们的结果表明，诱发凝视行为和手动动作之间可能存在重叠。然而，个体差异可能不能完全预示反射性社会行为。我们的结果表明，诱发凝视行为和手动动作之间可能存在重叠。然而，个体差异可能不能完全预示反射性社会行为。我们的结果表明，诱发凝视行为和手动动作之间可能存在重叠。然而，个体差异可能不能完全预示反射性社会行为。
