 The authors rightly caution, however, that success in meeting these special needs must be judged through practical use over time.They also point out that the KABC should not be regarded as "the complete test battery"; like any other test, it should be supplemented and corroborated by other instruments to meet individual needs, such as the Stanford-Binet, Wechsler Adult Intelligence Scale, Wechsler Intelligence Scale for Children, McCarthy scales, or neuropsychological tests.The original KABC was developed from neuropsychological theory, merging left brain-right brain research on cerebral specialisation (e.g., Sperry, 1968) with Luria’s sequential simultaneous processing dichotomy (Luria, 1966) and work in cognitive psychology.
