Dimensionality of anthropomorphism
● The previous work on humanlikeness in HRI considered anthropomorphism as a uni-dimensional space from a machine to a human.
● Studies of dehumanization can indicate that anthropomorphism can be multi-dimensional
Potential benefits
HRI can be improved by attributing a robot only with humanlike characteristics that can facilitate the interaction and avoiding implementing human attributes that could hamper it
Research questions
● Are there two dimensions of anthropomorphism?– Does a robot’s intelligence affect mainly UH
dimension?
– Does a robot’s emotionality affect mainly HN dimension?

Relationship between UH and HN
● Strong and highly significant correlation between these two dimensions
● Only for low HN subjects their HN and UH scores were correlated
● Similarly, only for low UH subjects their HN and UH scores were correlated
● The relation between these two dimensions is not completely straightforward
Conclusions
● Intelligence did not affect the measures of anthropomorphism, but emotionality did
● It is possible that other factors from UH dimension affect anthropomorphism
● Alternatively only HN dimension affects human-likeness
● The results indicate potential multi-dimensionality of anthroporphism in HRI
