About
Dawid Ratajczyk is a researcher specializing in human-robot interaction, the uncanny valley hypothesis, and the psychological dimensions of artificial characters. His work sits at a compelling intersection of cognitive psychology, psychophysiology, and emerging technologies, exploring how people emotionally and physiologically respond to increasingly humanlike robots and virtual agents. Ratajczyk's most notable contributions include a pioneering 2022 study (17 citations) that harnessed Natural Language Processing of YouTube comments to investigate the uncanny valley phenomenon in ecologically valid, real-world settings — a methodological innovation that moved the field beyond traditional laboratory constraints. His broader body of work employs diverse methods, from electrodermal activity measurement and response time analysis to virtual reality environments, providing a multifaceted empirical picture of the uncanny valley effect. A 2023 study (12 citations) broke new ground by examining how essentialism beliefs about human uniqueness shape discomfort responses across both VR and on-screen presentations. More recently, Ratajczyk has extended his inquiry into social perception, investigating how behavioral cues like dominance and submissiveness interact with robot humanlikeness. With a growing citation record and methodologically diverse portfolio, his research makes meaningful contributions to understanding how humans navigate an increasingly robot-populated world.
