Individual differences in dichotic fusion experiments could be based on a number of different principles. The current working hypothesis suggests that the phenomenon reflects a language-binding effect language-bound LB individuals perceive and remember events in language terms while language- optional LO individuals can use language structures or set them aside depending on task demands. The author explored an alternative interpretation, that the two types of individuals differ in overall intelligence levels. Three samples of subjects classified as LB or LO were studied, with about 50 subjects in each. There were no statistically reliable differences in overall scores between LBs and LOs for either the Scholastic Aptitude Test or a standard intelligence test. Thus it appears that the LB-LO distinction is not based on differences in overall intellectual ability. However, other aspects of the data suggested that the two groups may achieve intelligent behavior in different ways.
