Predicting Language in Children with ASD Using Spontaneous Language Samples and Standardized Measures.

This longitudinal study examined the degree to which standardized measures of language and natural language samples predicted later language usage in a heterogeneous sample of children with autism spectrum disorder (ASD), and how this relationship is impacted by ASD severity and interventions. Participants with a diagnosis of ASD (N = 54, 41 males) completed standardized assessments of language and social functioning; natural language samples were transcribed from play-based interactions. Findings indicated that standardized language measures, natural language measures, and ADOS severity were each unique predictors of later lexical use. Intervention types also appeared to impact later language; in particular, participation in mainstream inclusion accounted for significant amounts of variance in children's mean length of utterance at T3.

Say that again: Quantifying patterns of production for children with autism using recurrence analysis.

The current research study characterized syntactic productivity across a range of 5-year-old children with autism and explored the degree to which this productivity was associated with standardized measures of language and autism symptomatology. Natural language samples were transcribed from play-based interactions between a clinician and participants with an autism diagnosis. Speech samples were parsed for grammatical morphemes and were used to generate measures of MLU and total number of utterances. We applied categorical recurrence quantification analysis, a technique used to quantify patterns of repetition in behaviors, to the children's noun-related and verb-related speech. Recurrence metrics captured the degree to which children repeated specific lexical/grammatical units (i.e., recurrence rate) and the degree to which children repeated combinations of lexical/grammatical units (i.e., percent determinism). Findings indicated that beyond capturing patterns shown in traditional linguistic analysis, recurrence can reveal differences in the speech productions of children with autism spectrum disorder at the lexical and grammatical levels. We also found that the degree of repeating noun-related units and grammatical units was related to MLU and ADOS Severity Score, while the degree of repeating unit combinations (e.g., saying "the big fluffy dog" or the determiner-adjective-adjective-noun construction multiple times), in general, was only related to MLU.

Language Growth in Young Children with Autism: Interactions Between Language Production and Social Communication.

Young children with autism spectrum disorder (ASD) present with a broad range of spoken language abilities, as well as delays in precursor skills such as gesture production and joint attention skills. While standardized assessments describe language strengths, the Communication and Symbolic Behavior Scales (CSBS-DP) is a particularly robust measure as it additionally characterizes precise aspects of social communication. This study provides a unique contribution by assessing the interactional effects of CSBS-DP Social Composite performance with early language samples on later language outcomes. Our results indicate that multiple social communication elements significantly interact with early spoken language to predict later language. Our findings also highlight the transactional relationship between early spoken vocabulary and social communication skills that bolster language development growth.

Which Preschool Children With Specific Language Impairment Receive Language Intervention?

Purpose: Potential biases in service provision for preschool children with specific language impairment (SLI) were explored. Method: In Study 1, children with SLI receiving treatment (SLI-T) and those with SLI not receiving treatment (SLI-NT) were compared on demographic characteristics and developmental abilities. Study 2 recruited children with articulation disorders receiving treatment (ARTIC-T) to determine if knowing service provision status influenced the results of Study 1. Results: In Study 1, the SLI-T group was rated by teachers as having poorer executive functioning than children in the SLIT-NT group, and the SLI-T group also came from families whose mothers had more education. These 2 variables alone predicted SLI-T and SLI-NT group membership with 84% accuracy. In Study 2, the ARTIC-T group were perceived as having comparable executive functioning to the SLI-NT group and better than the SLI-T group, indicating that teachers' knowledge of service provision did not influence their ratings of children's executive functioning. Discussion: Preschool children with SLI, whose mothers have higher education levels and whose teachers perceive them as having poorer executive functioning, are more likely to receive intervention. Recognizing service delivery biases is critical for improving early provision of intervention for this population.

Grammatical Language Impairment in Autism Spectrum Disorder: Exploring Language Phenotypes Beyond Standardized Testing.

Linguistic and cognitive abilities manifest huge heterogeneity in children with autism spectrum disorder (ASD). Some children present with commensurate language and cognitive abilities, while others show more variable patterns of development. Using spontaneous language samples, we investigate the presence and extent of grammatical language impairment in a heterogeneous sample of children with ASD. Findings from our sample suggest that children with ASD can be categorized into three meaningful subgroups: those with normal language, those with marked difficulty in grammatical production but relatively intact vocabulary, and those with more globally low language abilities. These findings support the use of sensitive assessment measures to evaluate language in autism, as well as the utility of within-disorder comparisons, in order to comprehensively define the various cognitive and linguistic phenotypes in this heterogeneous disorder.

Do Adolescents With Specific Language Impairment Understand Driving Terminology?

Purpose: This study examined if adolescents with specific language impairment (SLI) understand driving vocabulary as well as their typically developing (TD) peers. Method: A total of 16 adolescents with SLI and 16 TD comparison adolescents completed a receptive vocabulary task focused on driving terminology derived from statewide driver's manuals. Results: The SLI group understood fewer driving-related terms when compared with the TD comparison group. Although both groups performed comparably in understanding simple noun driving terminology, the SLI group had greater difficulty comprehending compound noun and verb driving terms. Discussion: The decreased understanding of terms found in driver's manuals for adolescents with SLI has implications for how they access necessary information for learning the driving rules, regulations, and procedures important for securing a driver's license.

Specific language impairment and executive functioning: parent and teacher ratings of behavior.

PURPOSE: The current study used the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P; Gioia, Espy, & Isquith, 2003), a rating scale designed to investigate executive behaviors in everyday activities, to examine the executive functioning of preschool children with specific language impairment (SLI) relative to their typically developing (TD) peers. METHOD: Nineteen preschool children with SLI were age- and gender-matched to 19 TD peers. Both parents and teachers of the participants completed the BRIEF-P. RESULTS: The executive functioning of children with SLI were rated significantly worse than those of controls by both parents and teachers. Adults' perceptions of the children's executive functioning significantly correlated with the children's language abilities. CONCLUSION: Parent and teacher perceptions of executive functioning in children with SLI align with prior findings of executive deficits that have been documented on neuropsychological assessments and experimental tasks. Furthermore, the results provide additional supporting evidence of the relationship between language abilities and executive functioning in early child development.
