Title
The Effects Of Chaos Characteristic And Periodicity Of Luminance Change On Animacy Perception
Abstract
Although humans perceive animacy in blinking fireflies, humans do not perceive animacy in flashing traffic lights. In the present study, we conducted a psychological experiment to investigate which characteristics of temporal changes of luminance affect animacy perception in humans. Unpredictability in temporal change might be one of the key factors that cause animacy perception. We focused on the periodicities and chaos intensities of time series because both characteristics are related to the subjective impression of predictability. Furthermore, we investigated the effects of top-down categorical knowledge on the animacy perception of an entity. The participants were asked to rate videos in which the luminance of a target entity (i.e., a squid, charcoal fire, or power lamp) changed according to pre-defined periodicities and chaos intensities. The experimental results indicated that the participants perceived animacy strongly based on luminance changes with periodic and high chaos intensities and that animacy was not affected by the chaos intensity of aperiodic change. These results imply that the periodicity of a time series contributes more strongly to the cause of human animacy perception than the chaos characteristics.
