AbstractPareidolia refers to the perception of recognizable forms in noisy or ambiguous stimuli. It has mostly been studied in the context of pathologies such as schizophrenia and dementia. However, pareidolic perception occurs in general population without associated psychotic symptoms. This phenomenon is conceived as a compensatory perceptual mechanism that enables the brain to deal with ambiguous information. It has been hypothesized that pareidolia would be related to the emergence of creative ideation. In this study, we investigated the effect of fractal dimension on pareidolic perception by asking participants to perceive as many recognizable forms as possible in a set of Fractional Brownian Motion images with varying fractal dimensions. In addition, we further investigated, using questionnaires, whether creativity, openness personality trait and schizotypy are linked to pareidolic perception. Results show that creativity facilitates pareidolic perceptions and that this effect interacts significantly with the state of flow.
