Abstract

General Psychophysical Account of Re-presentation.-- In the last chapter we saw that even in those psychophysical processes where the sense organs were most obviously engaged, the effects of past experience were very conspicuous. This fact will suggest at once the probable difficulty of establishing any absolute line of demarcation between processes of perception and those which, in common untechnical. language, we call memory and imagination. We shall find as we go on that this difficulty is greater rather than less than our first impressions would indicate, and it will be well to come to the matter with the understanding that we are examining various stages in the development..
