Abstract/OtherAbstract:
The aim of this chapter is to discuss evidence bearing on two related issues, namely, first, whether the neural pathways of subliminal perception are the same as those subserving suprathreshold perception. Second, whether the pathways for subliminal perception in normals are similar to those subserving blindsight in brain-damaged patients. As to the former question, the overall balance is in favor of the different-pathway hypothesis while a tentative answer to the second question might be that blindsight is basically similar to subliminal perception in normals. The differences undoubtedly existing between the two conditions depend mainly on the differences in the stimuli used to reveal them.
