Laterality of Function in the Infant: Historical and Contemporary Trends in Theory and Research11Some of the historical material in this chapter first appeared, in different form, as part of a general review of early theories of handedness (Harris, 1980a). Brief, selected accounts also have been presented at the 1980 NATO Advanced Study Institute on Neuropsychology and Cognition, Augusta, Georgia (Harris, 1982), and at the 1980 52nd Annual Meetings of the Midwestern Psychological Association, Saint Louis, Missouri. Research for this chapter was supported, in part, by the College Scholar Program of the College of Social Science, Michigan State University, and by grants from the Michigan State University Foundation and The Spencer Foundation.
