Wechsler Intelligence Scale for Children-Third Edition (wisc-iii)

Intelligence can manifest itself in many forms and has been defined and measured in various ways. Although this chapter will not delve into the theories, it will define intelligence according to David Wechsler’s conception that intelligence is not a particular ability, but “the aggregate or global capacity of the individual to act purposefully, to think rationally, and to deal effectively with his or her environment.” Intelligence is closely intertwined with aspects of one’s personality and overall adaptive functioning.
