摘要：The article considers the diversity of categorical perception effects on human emotional facial expressions. We define the methodological requirements to research the structure of perceptual space of emotional expressions. In the experimental series with the use of computer morphed transitions between all possible pairs of 7 basic emotions, three main patterns of transitional expressions were revealed: peak pattern (classic categorical effect), plateau and flat distribution (absence of categorical effect). The results of the study also show that the stability of the effect depends on the specific emotional content of the stimuli used.
