Identification of Emotion in a Dichotic Listening Task: Event-Related Brain Potential and Behavioral Findings

“…Tallal, Stark, and Mellis (1985) reported that it may be the rapid change in acoustic features that is responsible for left hemisphere superiority for speech processing. The finding of greater N100 amplitudes over the left hemisphere for the phonemic aspect of the consonant-vowel syllables is consistent with other reports of greater left than right hemisphere ERP components in response to language processing (Nelson, Collins, & Torres, 1990). In contrast, information required for the emotion category classification may have been primarily revealed in the later portion of the consonant-vowel utterance, which ranged from 595 to 965 ms. Further experimentation with the stimuli used in this study, in which the task requirement would be identification of CV syllables rather than the emotional tone of the syllables, would enable dissociation of ERP findings related to discrimination of temporal-phonemic characteristics of the stimuli from those related to emotion perception.…”

Cognitive neuroscience of aging: Contributions of functional neuroimaging

“…Scand J Psychol 42 (2001) and behavioral studies. In event-related potentials (ERPs) studies, language-related effects tend to be greater over left hemisphere electrodes (e.g., Elmo, 1987;Nelson, Collins & Torres, 1990). Consistent with this pattern, Bellis et al (2000) have recently found that, in children and younger adults, a N1 effect associated with auditory processing of syllables occurred only in the left hemisphere.…”
