CEREBRAL LATERALIZATION INDUCED BY DICHOTIC LISTENING TO FILTERED AND UNFILTERED STIMULI: OPTIMIZING AUDITORY INPUT FOR FOREIGN LANGUAGE LEARNERS

Andrew Lian, Xirui Cai, Haoqiang Chen, Jibing Ou, Wei Zheng.

Abstract
This case study explores the optimal auditory input for ESL learners in an attempt to understand how foreign languages are processed by the brain. It adopts an Event-Related Potential (ERP) approach using dichotic stimuli. Low-pass filtered (< 320 Hz) and unfiltered spoken language was variously presented to the left and right ears of the participant. Three configurations of stimuli were presented in the Oddball paradigm: filtered stimuli in the left ear and unfiltered stimuli in the right ear (FL-R), unfiltered stimuli in the left ear and filtered stimuli in the right ear (L-FR), and filtered stimuli in both ears (FL-FR) were performed as target deviant stimuli. In addition, unfiltered stimuli (NL-NR) were sent to both ears and designed to act as standard stimulation, while environmental sounds such as trains and birds, were considered as novel stimulation. The language-related ERP components N400 and P600 that correlate with semantic and syntactic manipulations respectively were analyzed. It was discovered that optimal and non-optimal configurations for auditory input do in fact exist and that these may be of value in language-learning contexts. Furthermore, compared with linguistic signals, ERP components elicited by environment sounds are neither predictable nor stable.

Key words: ESL learners, dichotic listening, low-pass filtered stimuli, ERP, optimal auditory input
