New Directions in Mental-Imagery Research

Abstract

Mental imagery typically involves the voluntary retrieval and representation of a sensory memory, but it can also sometimes be involuntary. Despite mental imagery having been a topic of interest for thousands of years, the methodological tools necessary to scientifically probe its underlying mechanisms have only recently been developed. New methods in behavioral psychophysics (the binocular-rivalry technique) and brain imaging (decoding techniques) have been developed and utilized to uncover many new insights into the mechanisms and brain areas involved in mental imagery. These insights are igniting further empirical and theoretical work into imagery itself as well as its role in many high-level cognitive processes and mental disorders.
