Computer-modeled characters resembling real people sometimes elicit cold, eerie
feelings. This effect, called the uncanny valley, has been attributed to
uncertainty about whether the character is human or living or real. Uncertainty,
however, neither explains why anthropomorphic characters lie in the uncanny
valley nor their characteristic eeriness. We propose that realism inconsistency
causes anthropomorphic characters to appear unfamiliar, despite their physical
similarity to real people, owing to perceptual narrowing. We further propose that
their unfamiliar, fake appearance elicits cold, eerie feelings, motivating threat
avoidance. In our experiment, 365 participants categorized and rated objects,
animals, and humans whose realism was manipulated along consistency-reduced and
control transitions. These data were used to quantify a Bayesian model of
categorical perception. In hypothesis testing, we found reducing realism
consistency did not make objects appear less familiar, but only animals and
humans, thereby eliciting cold, eerie feelings. Next, structural equation models
elucidated the relation among realism inconsistency (measured objectively in a
two-dimensional Morlet wavelet domain inspired by the primary visual cortex),
realism, familiarity, eeriness, and warmth. The fact that reducing realism
consistency only elicited cold, eerie feelings toward anthropomorphic characters,
and only when it lessened familiarity, indicates the role of perceptual narrowing
in the uncanny valley.
