ABSTRACTThis study investigates whether number dissimilarities on subject and object DPs facilitate the comprehension of subject- and object-extracted centre-embedded relative clauses in children with Grammatical Specific Language Impairment (G-SLI). We compared the performance of a group of English-speaking children with G-SLI (mean age: 12;11) with that of two groups of younger typically developing (TD) children, matched on grammar and receptive vocabulary, respectively. All groups were more accurate on subject-extracted relative clauses than object-extracted ones and, crucially, they all showed greater accuracy for sentences with dissimilar number features (i.e., one singular, one plural) on the head noun and the embedded DP. These findings are interpreted in the light of current psycholinguistic models of sentence comprehension in TD children and provide further insight into the linguistic nature of G-SLI.

Mean Length Of Utterance

Several hypotheses have been offered to explain the grammatical morpheme difficulties observed in the speech of children with specific language impairment. Three of the accounts that could be evaluated in English were the focus of this study: the extended optional infinitive account, the implicit rule deficit account, and the surface account. Preschoolers with specific language impairment, a group of age controls, and a group of younger children matched for mean length of utterance were evaluated in their use of several theory-relevant grammatical morphemes. The findings revealed advantages for both the surface and extended optional infinitive hypotheses. In contrast, a test of the predictions based on the implicit rule deficit account suggested that the children studied here were not experiencing a deficit of this type.

Proper Modification

Purpose Compared with same-age typically developing peers, school-age children with specific language impairment (SLI) exhibit significant deficits in spoken sentence comprehension. They also demonstrate a range of memory limitations. Whether these 2 deficit areas are related is unclear. The present review article aims to (a) review 2 main theoretical accounts of SLI sentence comprehension and various studies supporting each and (b) offer a new, broader, more integrated memory-based framework to guide future SLI research, as we believe the available evidence favors a memory-based perspective of SLI comprehension limitations. Method We reviewed the literature on the sentence comprehension abilities of English-speaking children with SLI from 2 theoretical perspectives. Results The sentence comprehension limitations of children with SLI appear to be more fully captured by a memory-based perspective than by a syntax-specific deficit perspective. Conclusions Although a memory-based view appears to be the better account of SLI sentence comprehension deficits, this view requires refinement and expansion. Current memory-based perspectives of adult sentence comprehension, with proper modification, offer SLI investigators new, more integrated memory frameworks within which to study and better understand the sentence comprehension abilities of children with SLI.

Purpose The CATALISE group (Bishop, Snowling, Thompson, Greenhalgh, & CATALISE Consortium, 2016; Bishop, Snowling, Thompson, Greenhalgh, & CATALISE-2 Consortium, 2017) recommended that the term developmental language disorder (DLD) be used to refer to neurodevelopmental language deficit. In this tutorial, we explain the appropriate application of the term and present advantages in adhering to the CATALISE recommendations. Conclusion Both specific language impairment and DLD refer to a neurodevelopmental condition that impairs spoken language, is long-standing and, is not associated with any known causal condition. The applications of the terms specific language impairment and DLD differ in breadth and the extent to which identification depends upon functional impact. Use of the term DLD would link advocacy efforts in the United States to those in other English-speaking countries. The criteria for identifying DLD presented in the CATALISE consensus offer opportunities for scientific progress while aligning well with practice in U.S. public schools.

Finite Verb

We examined the use of grammatical morphology by preschool-age English-speaking children with specific language impairment (SLI) as a function of their lexical diversity. Relative to a group of normally developing (ND) preschoolers, these children's use of finite-verb morphology lagged behind expectations based on the number of different verbs they used. Noun-related morphology fell below expectations based on overall lexical diversity. Differences between the ND children and children with SLI were also seen for the slope of the increases in finite-verb morphology as a function of lexical diversity, with shallower slopes in the SLI data. The findings of this study add to existing evidence suggesting that a measure of finite grammatical-morphology use has promise as a clinical marker of SLI in English.
