Blindsight and consciousness

Implications for understanding consciousness are considered by focusing on two behaviors whose mutual disparity indicates blindsight. Among the topics are: (a) the basis on which people report seeing something in particular; (b) two interpretations of blindsighted subjects' forced-choice guessing as affected by perceptual judgments outside subjects' awareness or as based on "pure perceptual knowledge" of which subjects have awareness, though this "knowledge" is nonconsciously acquired; (c) whether blindsight is "behavior divorced from awareness"; and (d) an interpretation of blindsight as a matter of responding to internal occurrences.
