Usage-based approaches to aphasia

Susanne Gahl
Lise Menn
2016

Background: Effects of word frequency on language comprehension and production are pervasive in speakers with and without aphasia. Frequency effects at the sentence level are likewise pervasive in neurotypical speakers, but have received relatively little attention in the aphasia literature. When discussed, frequency-based explanations have typically been dismissed as explanations of sentence-level deficits. Usage-based approaches to understanding the accessibility of clause and phrase structures are not widely used in aphasiology, in spite of their psycholinguistic plausibility.

An ultrasound investigation into articulatory variation into American /s/ and /r/

Sarah Bakst

This ultrasound study investigates articulatory variability in American English /r/ and /s/ production in onset and coda position, and in the context of the vowels /a, i, o/. Variability both between and within participants is examined. Between speakers, our data support the position of Brunner et al. that flatter palates are correlated with less articulatory variability. Within speaker, our data suggests that articulation of either /r/ or /s/ does not predict articulation of the other.

Articulatory variability and fricative noise in apical vowels

Matthew Faytak

Standard Mandarin (SM) apical vowels have tongue postures similar to the fricative consonants that obligatorily precede them, but are thought to lack the consonants’ fricative noise. Lee-Kim [10] argues that in SM apical vowels, a slight reduction of constriction at the tongue blade or tip reduces fricative noise, essentially resulting in syllabic approximants. Using lingual ultrasound to examine articulation of apical vowels in SM, we argue that other articulatory adjustments may also limit frication in apical vowels, but that these strategies are implemented variably such that some...

Contrastive and non-contrastive pre-stopping in Kaytetye

Kaytetye is one of the few Australian languages for which pre-stopping is contrastive for nasals. This paper provides the first quantitative data on the phonetic realization of contrastive pre-stopping for any Australian language. It also provides data on the hitherto unreported non-contrastive pre-stopping of laterals in Kaytetye. The findings demonstrate that contrastive nasal pre-stopping and non-contrastive lateral pre-stopping differ on three parameters: (a) the conditioning on the distribution of plain vs. pre-stopped realizations; (b) the comparative overall durations of pre-...

The A-map model: Articulatory reliability in child-specific phonology

This article addresses a phenomenon of long-standing interest: the existence of child-specific phonological patterns that are not attested in adult language. We propose a new theoretical approach, termed the A(rticulatory)-map model, to account for the origin and elimination of child-specific phonological patterns. Due to the performance limitations imposed by structural and motor immaturity, children’s outputs differ from adult target forms in both systematic and sporadic ways. The computations of the child’s grammar are influenced by the distributional properties of motor-acoustic traces...
