An Adaptation of the Hybrid Visual Habituation Paradigm to Assess Speech Perception in Young Children with Cochlear Implants

by Wilson, Janean D., M.A., THE GEORGE WASHINGTON UNIVERSITY, 2011, 47 pages; 1493560

Abstract:

Current speech perception methodologies for young children are limited to those that require behavioral and metacognitive responses from the participant. The visual habituation paradigm (VHP) is a procedure that uses novelty preference (measured by a child's looking time) to illustrate perception of novel auditory stimuli. The purpose of the current study was to determine whether a variant of the hybrid visual habituation paradigm (HVHP) could be used to measure individual differences in the perception of a of prosodic and segmental speech features in a group of deaf children with cochlear implants. Participants were assessed on the perception of three speech features (vowel height, lexical stress, intonation) using a modified HVHP. Analyses showed that all of the participants exhibited longer looking times to the novel auditory stimuli during the experimental trial. Additional analyses illustrated that the modified HVHP is a promising method for assessing the perception of vowel height, lexical stress and intonation in young children with cochlear implants.
