I see introspection to be of limited utility. Much of what the brain does has no cortical representation and as such, is not available to introspection.
Just for fun, try to bring saccades into your consciousness. The scanning and integration of objects is an observed behavior but try as I like, I can’t “experience” it.
Likewise, the loop of consciousness has a significant portion of the process in subcortical structures. We can draw a box about the “subconscious” but it is not available to introspection.
Emotions are a subcortical process - we usually become aware that we are being influenced by these these structures by the effect the chemical messengers have on the body.
