We investigated which item subsets of the Vineland-II can discriminate low-functioning preschoolers with ASD from matched peers with other neurodevelopmental disorders, using a regression analysis derived from a normative sample to account for cognitive and linguistic competencies. At variance with the typical profile, a pattern with Communication…

This study tested the hypothesis that children with speech sound disorder have generalized slowed motor speeds. It evaluated associations among oral and hand motor speeds and measures of speech (articulation and phonology) and language (receptive vocabulary, sentence comprehension, sentence imitation), in 11 children with moderate to severe SSD…

In this study, observed maternal positive engagement and perception of work-family spillover were examined as mediators of the association between maternal nonstandard work schedules and children's expressive language outcomes in 231 African American families living in rural households. Mothers reported their work schedules when their child was 24…

In the UK there is much concern about the educational progress of children from areas of significant social disadvantage entering primary school with impoverished language skills. These children are not routinely referred to speech and language therapy services and therefore education practitioners in schools deliver intervention to facilitate…

The purposes of the study were to determine (a) the ability of two spontaneous language measures, mean length of utterance in morphemes (MLU-m) and number of different words (NDW), to identify African American preschool children at low and high levels of language ability; (b) whether child chronological age was related to the performance of either…

This paper investigated the predictive ability of expressive vocabulary size and lexical composition at age 2 on later language and literacy skills from ages 3 through 11. Multivariate analysis of covariance was performed to compare 16 language and literacy outcomes between children with large expressive vocabulary size at 24 months (N = 1,073)…

Purpose: The aims of this article are twofold: (a) to offer a set of recommended measures that can be used for evaluating the efficacy of interventions that target spoken language acquisition as part of treatment research studies or for use in applied settings and (b) to propose and define a common terminology for describing levels of spoken…

Background: Verbal perseveration (i.e. excessive self-repetition) is a characteristic of male individuals with fragile X syndrome; however, little is known about its occurrence among females or its underlying causes. This project examined the relationship between perseveration and (1) gender, (2) cognitive and linguistic ability, and (3) language…

Cognitive and language skills of 39 siblings of children with autism (SIBS-A) and 39 siblings of typically developing children (SIBS-TD) at ages 4, 14, 24, 36, and 54 months were compared. Twelve of the 39 SIBS-A revealed a delay in cognition and/or language (including one child diagnosed with autism) compared to only two SIBS-TD. Developmental…

Designed to measure children's receptive and expressive language competence, this 57-item instrument inventories children's performance in the following eight language subareas: motor functions, memory functions, visual functions, tactile-kinesthetic functions, vocal functions, auditory functions, following directions, and language concepts. (This…

Examined morphosyntax in persons with Williams Syndrome (WS). Analyzed receptive language of English-speaking WS persons and grammatical gender assignment of French-speaking WS persons. Found within-domain dissociations in grammatical gender assignment across several sentence elements and difficulties in understanding embedded sentences, which…

Purpose: To scale language milestones in a group of 527 children to provide an instrument for screening language development. Procedure: The questionnaire regarding these milestones was completed by parental report. It was evaluated whether the scaled milestones satisfied the assumptions of the Mokken item response model.
