Perhaps, brain compared before-and-after or adjacent perceptions, and perception changes caused first sensation {perception change and first sensation}. Perhaps, brain compared perception and memory, and sense qualities arose from spatial-gradients, temporal-gradients, differences, or errors. For example, people can realize that motion does not have expected effect. Error can cause punishment or can lower reward. Perhaps, brain detected position differences, and sense qualities arose as movement perception. Perhaps, sense qualities arose as perceptual-process modification, distinction, realization, notice, feeling, or comparison. However, changes, differences, gradients, and errors use same units as original quantities and so are not new things.
