Understanding and production of prosody in children with Williams syndrome: A developmental trajectory approach

Preschool children's performance on Profiling Elements of Prosody in Speech-Communication (PEPS-C)

“…This test has a number of positive features and has therefore been used in a number of research studies investigating prosody in typical children and those with communication disorders (e.g. Peppé & McCann, 2003;Wells & Peppé, 2003;Wells, Peppé & Goulandris, 2004;Peppé, McCann, Gibbon, O' Hare & Rutherford, 2007;Martínez-Castilla & Peppé, 2008;Stojanovik, 2010Stojanovik, , 2011Foley, Gibbon & Peppé, 2011). Among its strengths is that the test adopts a psycholinguistic approach, which allows for identification of likely causation, i.e.…”

A few studies have included young children as language matched controls, for example, one study included typically developing children from age 4;8 upwards (Peppé et al, 2007).…”

“…A few studies have included young children as language matched controls, for example, one study included typically developing children from age 4;8 upwards (Peppé et al, 2007). Recent studies by Stojanovik (2010;2011) investigated prosody in children with conditions including Williams and Down syndrome and administered PEPS-C to typically developing children aged 4;2 years and older who were matched with the children with genetic syndromes on factors such as chronological and nonverbal mental age. Although Stojanovik does not comment specifically on the younger typically developing children's performance on the test, there is mention that some responses could not be scored.…”

Developmental trajectories of structural and pragmatic language skills in school‐aged children with Williams syndrome

“…Using a cross‐sectional developmental trajectory approach, Stojanovik () demonstrated a delayed onset and rate of development for various components of linguistic prosody in English‐speaking children with WS (CA 6–13 years; NVMA 3–7 years). Differences disappeared when comparing children with WS to NVMA matched TD controls.…”

An EPG analysis of /t/ in young people with Down's syndrome

“…Whilst prosody (Shriberg and Widder, 1990;Heselwood, Bray, and Crookston, 1995;Stojanovik, 2010) and voice production (Bolfan-Stosic and Hedever, 1999;Moura Cunha, Vilarinho, Cunha, Freitas, Palha, Pueschel, and Pais-Clemente, 2008;Lee, Thorpe, and Verhoeven, 2009) problems all contribute to the unintelligibility of this group, most studies tend to focus on segmental production, in particular the atypical production of consonants (Stoel-Gammon, 1980;Smith and Stoel-Gammon, 1983;Bleile and Schwarz, 1984;Van Borsel, 1988;Crosley and Dowling, 1989;1991;Kumin, Councill, and Goodman, 1994;Roberts, Long, Malkin, Barnes, Skinner, Hennon, and Anderson, 2005).…”
