The Orton's hypothesis about hemispheric lateralization and reading writing performance revisited: an ex post facto study in Spanish context


This paper attempts to inquiry the connections between hemispherical laterality and reading-writing performance, based on the theory that Samuel T. Orton established over 60 years ago. No evidence has been found to show a significant correlation between both constructs. Therefore, the widely held belief that the one depends on the other can be refuted.
