“…The first fMRI study, which compared brain activity triggered by action observation of robotic versus human actions, has suggested that internal simulation of actions is triggered only by biological agents (Tai, Scherfler, Brooks, Sawamoto, & Castiello, 2004). Accordingly, it has also been shown that there is less activity in areas associated with empathy and less emotional distress when people observe abusive behavior directed to a robot in comparison to a human (Rosenthal-von der P€ utten et al, 2014). However, more recent investigations have reported internal action simulation, although weaker than for human actions, for non-goal-directed robotic actions (Bisio et al, 2014;Hofree, Urgen, Winkielman, & Saygin, 2015).…”
