Cognitive psychology and mental handicap

The psychology of mental handicap has been influenced by two traditions in general psychology, pychometric measurement following Binet and experimental psychology first initiated by Wundt. The weakness of the former is its lack of explanatory power and, of the latter, its lack of sound alignment with the neuropathology of mental handicap. A closer association of experimental psychology and neuropathology might help us to reframe our concepts of intelligence, cognitive functions and their handicaps.
