Robot face memorability is affected by uncanny appearance

Human face recognition is influenced by various social and environmental constructs. For example, both age and race can affect the likelihood that a human face will be correctly recalled. General face appearance (i.e. friendly or untrustworthy faces) can also influence memorability. As human-robot i...
