PURPOSE The purpose of this exploratory study was to examine the variability and predictors of expressive vocabulary development in children with autism and very delayed language. METHOD This study involved 35 children with autism whose initial chronological ages were between 20 and 71 months and whose initial expressive vocabularies were less than 60 words. Their expressive vocabularies were measured at baseline and at 6, 12, and 24 months following the start of intervention using the…

Prelinguistic predictors of language development in children with autism spectrum disorders over four-five years.
TLDR
When all factors were considered simultaneously, children's ability to participate in games and routines was the only significant predictor of language production over time, which has implications for understanding the complex factors that affect developmental outcomes.
Preschoolers with autism show greater impairment in receptive compared with expressive language abilities.
TLDR
Recognition of the marked receptive language impairment relative to expressive language, found to affect at least one-third of preschoolers with autism in this sample, has important implications for interacting with these children and for informing appropriate targets in language and communication intervention.
Preschool language variation, growth, and predictors in children on the autism spectrum.
TLDR
Findings indicate that it is possible, by 2½ years, to predict language growth for children with ASD across the preschool years and identify factors that discriminate between children who remain minimally verbal at 5½  years from those with high language proficiency.
Examining classification accuracy for expressive language skills of children with autism spectrum disorder according to object play and imitation scores
TLDR
There was a significant difference between the object play and imitation scores of children with ASD who had and did not have expressive language skills, and the effect of object play score was higher in this classification process than imitation score.
On the Value of Repeated Measures of Intention, Vocabulary, and Grammar for Children With Autism
Purpose: Repeated measures of communica- tive intention, vocabulary, and grammar were collected from a child with autism during the course of commu- nity-based treatment. Method: Data were collected…
Does phonetic repertoire in minimally verbal autistic preschoolers predict the severity of later expressive language impairment?

TLDR
The findings suggest that there are factors other than social skills that influence language development in autism, and careful assessment of speech production should be considered when language does not develop as expected.
Longitudinal Development of Receptive Vocabulary in Children with Cerebral Palsy and Anarthria: Use of the MacArthur-Bates CDI
TLDR
Receptive vocabulary scores from the MCDI are increasing at a reduced pace for most children with cerebral palsy and anarthria, and more sensitive measures of language assessment are necessary to gain a complete picture of their language ability levels.
Predictors of longer-term development of expressive language in two independent longitudinal cohorts of language-delayed preschoolers with Autism Spectrum Disorder.
TLDR
Marked deficits in fine motor skills may be a salient proxy marker for identifying language-delayed children with ASD who are at risk for persistent language impairments, adding to the literature demonstrating a relation between motor and language development in ASD.
Comparing early language development in monolingually-exposed and bilingually-exposed young children with autism
By definition, individuals with autism have marked language delays. Parents of children with autism are often advised not to raise their child with autism in a bilingual environment because of the…
Pragmatic, lexical and grammatical abilities of autistic spectrum children.
TLDR
There are associations between grammatical and pragmatic performances in the language of children with autism spectrum disorders and along the studied period of language therapy.

Parents' report of vocabulary and grammatical development of African American preschoolers: child and environmental associations.
TLDR
Results showed that children's vocabulary and utterance length grew linearly over time between 18 and 30 months of age, and there are indications that some parents may be under-reporting their children's early vocabulary and grammatical development.
Validity of parent report measures of vocabulary development for children with Down syndrome.
TLDR
The results establish the validity of parent measures of vocabulary development for children with Down syndrome and confirm their validity for typically developing children.
Measuring early language development in preschool children with autism spectrum disorder using the MacArthur Communicative Development Inventory (Infant Form)
TLDR
Comprehension of words was delayed in comparison to word production, and production of early gestures was delayed relative to production of later gestures, but other aspects of language development were similar to that found in typically developing infants, including word comprehension being in advance of word production in absolute terms.
Continuity and change in the social competence of children with autism, Down syndrome, and developmental delays.
TLDR
Improvements in early communication and play skills may have long-term consequences for later language and social competence in these groups of children.
An investigation of language impairment in autism: Implications for genetic subgroups
TLDR
There was significant heterogeneity in their language skills, although across all the children, articulation skills were spared and the profile of performance across the standardised measures for the languageimpaired children with autism was similar to the profile that defines the disorder specific language impairment (or SLI).
Predictors of outcome among high functioning children with autism and Asperger syndrome.
TLDR
The results support the emphasis of early intervention programmes on language but more work needs to be done on understanding variables that influence outcome in social skills and autistic behaviours, particularly in those with AS.
Regression and word loss in autistic spectrum disorders.
TLDR
Results indicated that the acquisition of a small number of spontaneous words used meaningfully and consistently followed by loss of all words, often associated with other social changes, was unique to children diagnosed at 5 years with ASD.

TLDR
Thirty-five children who received an autism spectrum diagnosis at the age of 2 years were re-evaluated 2 years later to examine factors related to the development of spoken language to predict an aggregate measure of language outcome at age 4.

TLDR
A newly revised questionnaire for the assessment of vocabulary and syntactic development, the MacArthur Communicative Development Inventory: Toddlers, is evaluated and concurrent validity correlations demonstrate high validity for parent report in both domains.
Outcomes of early language delay: I. Predicting persistent and transient language difficulties at 3 and 4 years.
TLDR
Relations between language and nonverbal abilities at 2 years and outcome at 3 and 4 years within the ELD group were highly statistically significant, effect sizes were small, and classification of outcome on the basis of data on 2-year-olds was far too inaccurate to be clinically useful.
