However, there were differences in response within meaningful words as well as between meaningful and non-meaningful words which may be explained by the characteristics of embedded words and the position-specific probability of phoneme occurrence in words. Also, dipole source analysis suggested that dipole strength was stronger in the left than the right cortical region for meaningful words. However, no significant differences between diotic and dichotic presentation were found for the participants preference ratings, or their judgments of intended emotion. As predicted there was a REA for meaningful words compared to non-meaningful words. (N 35) were tested in a single response diotic listening task with consonant- vowel-syllables presented in 144 pairs, while instructed. Eighteen normal-hearing listeners were presented with a repeating diotic standard ( or ) and an occasional dichotic deviant (a standard presented to one ear and a deviant, , or presented to the opposite ear). The mismatch negativity (MMN) and a late negativity (LN) were measured for bisyllabic meaningful words and non-meaningful pseudowords, which differed in their second syllable. This study objectively probed the relationship between ear advantage and hemispheric dominance in a dichotic-listening situation, using event-related potentials (ERPs). This REA is assumed to be associated with a left-hemisphere dominance for meaningful speech processing. Classic dichotic-listening paradigms reveal a right-ear advantage (REA) for speech sounds as compared to non-speech sounds. Listening to a message in one ear and ignoring the different mesaage in the other ear.
