I think by "immediate reaction" you mean that echolocation gives feedback as to posture and muscle tone, which makes sense, though I'm not sure how the frequency ranges typically used for echolocation compare to the frequency ranges typically used for communication. By "state of mind" are you saying that state of mind produces physiological changes in the brain that are detectable via echolocation?
