About

Ruth S. Nagayama is a pioneering cognitive scientist whose work has fundamentally shaped our understanding of the "uncanny valley"—the unsettling feeling evoked by nearly human-like artificial figures. Her landmark 2007 paper, "The Uncanny Valley: Effect of Realism on the Impression of Artificial Human Faces," has amassed over 565 citations, establishing the foundational framework for how realism in humanoid robots, dolls, and masks triggers discomfort. Nagayama’s research extends beyond robotics into visual perception, as demonstrated in her 2009 study "Probing the Uncanny Valley with the Eye Size Aftereffect" (22 citations), which revealed that abnormal features on natural faces provoke unease, while artificial faces do not always elicit the same response. This insight challenged prevailing assumptions and opened new avenues for exploring how the brain distinguishes between natural and artificial stimuli. Her work has become essential reading for researchers in human-robot interaction, computer graphics, and perceptual psychology. By bridging cognitive science and robotics, Nagayama has not only advanced theoretical knowledge but also provided practical guidance for designing more acceptable artificial faces, making her a central figure in the quest to create comfortable human-machine interfaces.
