Considering that the nature of the input is one of the most important variables in determining how the brain will process information, findings from tachistoscopic studies aimed at assessing hemispheric specializations are examined in terms of the characteristics of the incoming information either available or required for processing. The basic features of the tachistoscopic technique are analyzed, and a framework for further investigation is suggested along with a reinterpretation of existing evidence. In a subsequent series of four experiments, several assumptions and interpretations made earlier are empirically tested. In a second series of three experiments, hemispheric asymmetries are examined with respect to the properties of the visual system and its capacity to extract information in terms of the spatial-frequency spectral components of a stimulus. Methodological and theoretical implications of the results are discussed, and an account of cerebral specialization suggesting a hemispheric sensitivity to different aspects of the same information is proposed.
