“…Interactions between the neural systems responsible for language and those responsible for speech motor control have been frequently observed. In typically developing children, for example, increases in syntactic complexity and utterance length are associated with articulatory simplifications (Prelock & Panagos, 1989), increased articulatory error production (Kamhi, Catts, & Davis, 1984), and increased speech motor variability (Maner, Smith, & Grayson, 2000). Additionally, typically fluent children as well as children who stutter demonstrate higher disfluency rates under conditions of increased length and syntactic complexity (Logan & Conture, 1997;Ratner & Sih, 1987;Silverman & Ratner, 1997;Yaruss, 1999;Zackheim & Conture, 2003).…”

Though anecdotal reports link certain speech disorders to increases in autonomic arousal, few studies have described the relationship between arousal and speech processes. Additionally, it is unclear how increases in arousal may interact with other cognitive-linguistic processes to affect speech motor control. In this experiment we examine potential interactions between autonomic arousal, linguistic processing, and speech motor coordination in adults and children. Autonomic responses (heart rate, finger pulse volume, tonic skin conductance, and phasic skin conductance) were recorded simultaneously with upper and lower lip movements during speech. The lip aperture variability (LA variability index) across multiple repetitions of sentences that varied in length and syntactic complexity was calculated under low- and high-arousal conditions. High arousal conditions were elicited by performance of the Stroop color word task. Children had significantly higher lip aperture variability index values across all speaking tasks, indicating more variable speech motor coordination. Increases in syntactic complexity and utterance length were associated with increases in speech motor coordination variability in both speaker groups. There was a significant effect of Stroop task, which produced increases in autonomic arousal and increased speech motor variability in both adults and children. These results provide novel evidence that high arousal levels can influence speech motor control in both adults and children.

“…In addition, not all studies have demonstrated all predicted interactions (e.g., Kamhi et al, 1984;Streim and Chapman, 1987). Despite this, a limited capacity, interactionist perspective of language impairment has remained central to assessment and intervention for language impairments in the 1990s.…”

The effect of semantic inconsistency on performance of an auditory sentence grammaticality judgement task was investigated with 69 school-age children with and without language-learning disabilities (LD). Children judged the grammatical correctness of semantically consistent sentences; for example, She had lovely catlike eyes and *The catlike wouldn't stop purring (where * indicates an ungrammatical sentence). They also judged the correctness of semantically inconsistent sentences; for example, The catlike corn wasn't picked and *They flew through the catlike. Children with and without LD showed high accuracy in correctly identifying grammatically correct sentences that were semantically consistent, but showed substantially lower accuracy in identifying sentences as grammatical when they were semantically inconsistent. Although semantic inconsistency affected identification of ungrammatical sentences for each group, the effect was significantly greater for LD children than for their typically-developing (TD) peers. In identifying both grammatical and ungrammatical sentences, the LD children's performance was similar to a group of younger, typically-developing children with comparable language skills (i.e., children matched for raw score on a test of language abilities). The finding that children's task performance can be affected by competing linguistic demands within the task is interpreted within a limited capacity, interactionist perspective of language impairment.

“…It is generally assumed that linguistically more complex forms are more challenging for children to acquire or produce (Bloom, 1970;Brown & Hanlon, 1970;Kamhi, Catts, & Davis, 1984). In particular, researchers have noted that words with simple syllable structures appear earlier in development, with 1 According to some accounts of syllable structure, liquids and nasals followed by -s can be syllabified as part of a branching coda, whereas obstruent+s clusters, which violate the sonority sequencing principle, must be syllabified as a singleton coda consonant plus an -s appendix at the higher level of the syllable (Selkirk, 1982;see Kirk & Demuth, 2005, for discussion).…”

Phonological Constraints on Children's Production of English Third Person Singular -sPurpose: Children variably produce grammatical morphemes at early stages of development, often omitting inflectional morphemes in obligatory contexts. This has typically been attributed to immature syntactic or semantic representations. In this study, the authors investigated the hypothesis that children's variable production of the 3rd person singular morpheme -s interacts with the phonological complexity of the verb stem to which it is attached. Method: To explore this possibility, the authors examined longitudinal data from the spontaneous speech of 6 English-speaking children between ages 1;3 and 3;6 (years; months) and elicited imitations from a cross-sectional study of 23 two-year-olds (mean age of 2;2). Results: The results showed that children produced third person singular morphemes more accurately in phonologically simple coda contexts (e.g., sees) as compared with complex coda contexts (e.g., needs). In addition, children produced -s more accurately in utterance-final position as compared with utterance-medial position. Conclusions:The results provide strong support for the role of phonological complexity in explaining some of the variability in children's production of third person singular -s. This finding suggests that future research will need to consider multiple factors, including phonological and positional effects, in constructing a comprehensive developmental theory of both grammatical competence and processes of speech planning and production.
