Complexity in articulatory and segmental levels of production

Precision of phonological errors in aphasia supports resource models of phonological working memory in language production

“…These results show that simplifications that appear similar on the surface do not always have a common origin. To add to this, there is still debate on what exactly qualifies as articulatory simplification (see Romani et al, 2017;Berent, 2017;Buchwald, 2017;Goldrick, 2017;Pouplier et al, 2017;Ziegler, 2017). Nevertheless, there is agreement that at least some simplifications reflect processing at a level below phonemes and may thus be less relevant to the theories tested in this paper.…”

“…It is important to note that uncovering the origin of simplifications is not always straightforward. For example, Buchwald andMiozzo (2011, 2012) described two speakers diagnosed with non-fluent aphasia and apraxia of speech (participant D.L.E. and participant H.F.L.).…”

“…We extracted a number of simplifications with greater consensus in the literature and conducted a series of control analyses to test whether any length effects observed in the main analyses could alternatively be accounted for by articulatory simplification. Specifically, we used changes in markedness as simplification criteria (Galluzzi et al, 2015;Romani et al, 2017;Buchwald, 2017;Berent, 2017;cf., Ziegler, 2017). We used three primary dimensions along which consonants become less marked to determine simplifications.…”

Étude exploratoire du déficit phonologique dans l’aphasie vasculaire : Complexité des structures syllabiques

“…l'environnement contextuel. Toutefois certains auteurs montrent que la structure syllabique du mot, ou encore la position des segments au sein des syllabes influencent les réalisations des locuteurs atteints d'une aphasie (Wilshire & Nespoulous, 2003;Buchwald et Miozzo, 2012;Buchwald, 2017). Ces facteurs renvoient à la notion de complexité phonologique.…”

“…est tout aussi important. C'est ce qui a été mis en exergue dans certains travaux ces dernières décennies (Béland, 1985;Buchwald, 2009Buchwald, , 2017Buchwald et al, 2017;Nespoulous et Wilshire, 2003;Prince, 2016). Dans ce sens, une étude de Buchwald (2017: 490) expose que la position au sein de la syllabe (coda ou attaque par exemple) et le fait qu'un segment consonantique (i.e.…”
