The perception of clauses in 6- and 8-month-old German-learning infants : influence of pause duration and the natural pause hierarchy
type: CreativeWork
description: The present dissertation focuses on the question whether and under which conditions infants recognise clauses in fluent speech and the role a prosodic marker such as a pause may have in the segmentation process. In the speech signal, syntactic clauses often coincide with intonational phrases (IPhs) (Nespor & Vogel, 1986, p. 190), the boundaries of which are marked by changes in fundamental frequency (e.g., Price, Ostendorf, Shattuck-Hufnagel & Fong, 1991), lengthening of the final syllable (e.g., Cooper & Paccia-Cooper, 1980) and the occurrence of a pause (Nespor & Vogel, 1986, p. 188). Thus, IPhs seem to be reliably marked in the speech stream and infants may use these cues to recognise them. Furthermore, corpus studies on the occurrence and distribution of pauses have revealed that there is a strong correlation between the duration of a pause and the type of boundary it marks (e.g., Butcher, 1981, for German). Pauses between words are either non-existent or short, pauses between phrases are a bit longer, and pauses between clauses and at sentence boundaries further increase in duration. This suggests the existence of a natural pause hierarchy that complements the prosodic hierarchy described by Nespor and Vogel (1986). These hierarchies on the side of the speech signal correspond to the syntactic hierarchy of a language. In the present study, five experiments using the Headturn preference paradigm (Hirsh-Pasek, Kemler Nelson, Jusczyk, Cassidy, Druss & Kennedy, 1987) were conducted to investigate German-learning 6- and 8-month-olds’ use of pauses to recognise clauses in the signal and their sensitivity to the natural pause hierarchy. Previous studies on English-learning infants’ recognition of clauses (Hirsh-Pasek et al., 1987; Nazzi, Kemler Nelson, Jusczyk & Jusczyk, 2000) have found that infants as young as 6 months recognise clauses in fluent speech. Recently, Seidl and colleagues have begun to investigate the status the pause may have in this process (Seidl, 20…
