|Abstract:||Examines 2 theories of the development of hemispheric differences. One theory is that the hemispheres differ at all stages of sensory information processing, from early precategorical reception to the later cognitive elaboration of the information. An alternative is that hemispheric asymmetries arise only as a consequence of the different cognitive operations carried out in the 2 hemispheres during or following stimulus encoding into short-term memory and subsequent processing. In support of the first theory, a number of experiments have shown the superiority of the right hemisphere in simple perceptual tasks such as color perception, yet they are not congruent with the conclusion that hemispheric asymmetries are already present at early perceptual stages of visual information processing. In comparison, the few experiments designed to single out the stage at which asymmetries arise have shown that the hemispheres have common access to the early precategorical iconic stage and that the asymmetries arise as a consequence of encoding from iconic to short-term memory.
