In light of these advances, we propose that time is not fundamental. Mar 1, 2006 · The key notion of cognitive psychology since the collapse of behaviourism is that the authors build brain descriptions of the world of objects, which give perception and intelligent behaviour, and from patterns of stimulation at the eyes and ears and the other organs of senses, including touch, they project sensations of consciousness into the external world. This is a step toward solving the mind-body problem from the assumption that consciousness, not physics, is fundamental. Psychology may be involved in a similar transformation.
