ROSS, Elliott D., Jerold A. Edmondson, G. Burton Seibert, and Richard W. Homan. “Acoustic Analysis of Affective Prosody during Right-Sided Wada Test: A Within-Subjects Verification of the Right Hemisphere’s Role in Language.” Brain and Language 33 (1988): 128-45.
Reviews evidence from a within-subjects study of five right-handed patients, each undergoing a WADA test (which causes transient “paralysis” to each brain hemisphere separately, as a presurgical screening procedure for epileptics being considered for prophylactic commisurotomies). Findings show the left-hemisphere condition causing loss of propositional speech, and the right-hemisphere condition causing a loss of affective speech. These findings further confirm the contention that
the right hemisphere modulates dominantly the affective components of language.
