Broca?s and Wernicke?s discovery concerning brain language
function remains debatable. The research questions: a) Is there a
significant difference of accuracy among the rh, the lh, and the rh-lh in
inferring auditory sentences? b) Which hemisphere shows the highest
accuracy? and c) Do the rh, lh and rh-lh show consistent hemispheric
accuracy when inferring sentences and short dialogs? The research
results are useful for clarifying controversies against brain language
function and as a foundation of ?hemispheric-based listening?. This
study employed Behavioral Test with Post-test Only design. Sample
involved 120 students. Data were collected through a test and analyzed
with Two-way Anova. It is found that the hemispheric accuracy among
the rh, lh and rh-lh in inferring auditory sentences is significantly
different; the lh shows the highest accuracy in inferring auditory
sentences; and the rh, lh and rh-lh show inconsistent hemispheric
accuracy when inferring sentences and short dialogs.
