Abstract

The human visual system allows a number of molar activities, among them straightforward seeing and reflective seeing. Both of these activities include, as product and part of them, a stream of first-order, visual perceptual consciousness of the ecological environment and of the perceiver himself or herself as inhabiting the environment and acting or moving within it. The two respective component streams of first-order consciousness both proceed at certain brain centers and, in Gibson's sense, they are resonatings to the stimulus energy flux at the photoreceptors. But the two streams differ in that only the one that proceeds during reflective seeing involves inner consciousness of the component first-order, visual perceptual consciousness . In this sense, perceptual consciousness proceeds entirely nonconsciously during straightforward seeing. This is because inner consciousness is not a kind of response to first-order consciousness, but is an intrinsic dimension of the latter when it is proceeding consciously as opposed to nonconsciously. The content of first-order, visual perceptual consciousness during reflective seeing is importantly different from the content during straightforward seeing, notwithstanding their both being kinds of seeing in the literal, nonmetaphorical sense as characterized by Gibson's ecological approach to visual perception
