  Mind perception in robots has been an understudied construct in human-robot
interaction (HRI) compared to similar concepts such as anthropomorphism and the
intentional stance. In a series of three experiments, we identify two factors
that could potentially influence mind perception and moral concern in robots:
how the robot is introduced (framing), and how the robot acts (social
behaviour). In the first two online experiments, we show that both framing and
behaviour independently influence participants' mind perception. However, when
we combined both variables in the following real-world experiment, these
effects failed to replicate. We hence identify a third factor post-hoc: the
online versus real-world nature of the interactions. After analysing potential
confounds, we tentatively suggest that mind perception is harder to influence
in real-world experiments, as manipulations are harder to isolate compared to
virtual experiments, which only provide a slice of the interaction.
