Objective understanding of perceptual categorization in a dynamic visual world
Perceptual Categorization – the ability to organize sensory information into meaningful groups of different stimuli requiring identical responses – is one of the most important functions of the human mind. However, despite decades of behavioral research in Psychology, the mechanisms, development, neural basis and cultural grounding of perceptual categorization remain largely unknown and debated. In this presentation, I will use complex images to show how human perceptual categorization can be objectively defined and quantified with fast periodic stimulation coupled with simple recordings of electroencephalography (EEG). The collected implicit measures of perceptual categorization in a continuously changing visual environment are extremely robust and reliable at the individual level, which is highly valuable in the current difficult context of a replication crisis in psychology and cognitive neuroscience.
