The human mind is capable of not only being cognitive and registering experiences but also of being introspectively aware of these processes. Until now, scientists have not known if such introspection was a single skill or dependent on the object of reflection. Also unclear was whether the brain housed a single system for reflecting on experience or required multiple systems to support different types of introspection. A new study by UC Santa Barbara graduate student Benjamin Baird and colleagues suggest that the ability to accurately reflect on perceptual experience and the ability to accurately reflect on memories were uncorrelated, suggesting that they are distinct introspective skills. The findings appear in the Journal of Neuroscience.
