CEREBRAL SPEECH LATERALIZATION IN THE NATIVE-AMERICAN NAVAJO

Thirty pairs of dichotically presented CV syllables were administered to matched samples of Native American Navajo and Anglo subjects. While sex was not a significant factor, significant differences were evidenced in the performance of the Native American Navajo and Anglo subjects. As predicted, the Navajo subjects demonstrated a left ear advantage compared to the traditional right ear effect found in the Anglo subjects. These results are discussed as they relate to linguistic processing and neuropsychological theory. © 1979.
