Sid Kouider is a cognitive neuroscientist working on the neurobiological and psychological foundations of consciousness. He is mainly interested in how conscious and unconscious processes differ at both the psychological and neural level. He uses various behavioral and brain imaging methods (e.g., fMRI and EEG/MEG) to study how humans process things unconsciously (e.g., such as in situations of subliminal perception) and compares it to situations of conscious processing. This approach offers the opportunity to understand the functional and physiological specificity of consciousness and, ultimately, why we need both conscious and unconscious processing. Recently, he has extended this line of research to study the neural correlates of consciousness in pre-linguistic babies.
