Invisible Gorillas in the Mind: Internal Inattentional Blindness and the Prospect of Introspection Training.

Much of high-level cognition appears inaccessible to consciousness. Countless studies have revealed mental processes-like those underlying our choices, beliefs, judgments, intuitions, etc.-which people do not notice or report, and these findings have had a widespread influence on the theory and application of psychological science. However, the interpretation of these findings is uncertain. Making an analogy to perceptual consciousness research, I argue that much of the unconsciousness of high-level cognition is plausibly due to internal inattentional blindness: missing an otherwise consciously-accessible internal event because your attention was elsewhere. In other words, rather than being structurally unconscious, many higher mental processes might instead be "preconscious", and would become conscious if a person attended to them. I synthesize existing indirect evidence for this claim, argue that it is a foundational and largely untested assumption in many applied interventions (such as therapy and mindfulness practices), and suggest that, with careful experimentation, it could form the basis for a long-sought-after science of introspection training.
