Abstract:The uncanny valley represents a strong dip in affect when observing stimuli with a high degree of human-likeness but that are not quite the real thing. This valley is thought to be caused by a mismatch between the human qualities that people are led to expect and the nonhuman qualities that are observed. Keeping in mind the recent replicability crisis, we attempted to replicate two studies on the uncanny valley. While doing so we expanded upon the studies in question in various ways in order to provide a better basis for future research. We incorporated stimuli with varying degrees of human-likeness. Results showed a clear replication of the uncanny valley in the long condition. We were unable to reproduce a clear valley in the short condition; instead we noticed a shift to the left on the human-likeness axis. Furthermore, we could not approximate the full curve with morphed faces as our stimuli only captured the right upward slope out of the valley. Based on these observations, which are partly in line with our hypotheses, we attempt a theory on category confusion complemented by processing fluency as an explanation of the emotional response and the valley’s absence in the short condition.
