Exploring the rhythmic segmentation of heard speech using evoked potentials
Annie C. Gilbert, Victor J. Boucher, Boutheina Jemel, Université de Montréal
This study examines, via evoked potentials called closure-positive-shifts (CPSs), how listeners segment heard utterances on-line. The aim was to determine whether marks of rhythm groups in heard utterances can evoke CPSs independent of varying intonation and syntactic structures. Ten subjects were presented with sets of utterances bearing changing intonation and syntax and the results show that CPS is specifically evoked by marks of RGs.
