Despite earlier claims that language abilities are intact in individuals with Williams syndrome (WS), many studies have shown that language development is often delayed and atypical, that is, it develops in line with different cognitive abilities compared to typically developing populations. It is unclear, however, whether general cognitive…

Erlam & Ellis (2018) published, in "Canadian Modern Language Review", an experimental study that investigated the effect of input-based tasks on the acquisition of vocabulary and markers of plurality by adolescent near-beginner learners of L2 (second language) French. The present paper reports an approximate replication of the…

Forty-two adolescents with Down syndrome (DS) ages 10 to 21 years completed a battery of language and phonological memory measures twice, 2 years apart. Individual differences were highly stable across two years. Receptive vocabulary scores improved, there was no change in receptive or expressive grammar scores, and nonword repetition scores…

Research regarding specific strategies adolescent mothers (AMs) may utilize to facilitate early language and emergent literacy skills in their children is lacking. This exploratory study investigated AMs' perceived use of preselected common language and emergent literacy strategies and correlated their use of these strategies to their children's…

Purpose: The aim of this study was to investigate language growth in individuals with fragile X syndrome (FXS) from early childhood to adolescence and the influence of maternal responsivity on language growth. Method: We conducted a longitudinal analysis of language development in 55 youths (44 males, 11 females) with FXS. Data collection spanned…

Purpose: Pragmatic language difficulties have been documented as part of the FMR1 premutation phenotype, yet the interplay between these features in mothers and the language outcomes of their children with fragile X syndrome is unknown. This study aimed to determine whether pragmatic language difficulties in mothers with the "FMR1"…

Background: Delayed, abnormal language is a common feature of autism and language therapy often a significant component of recommended treatment. However, as with other disorders with a language component, we know surprisingly little about the language trajectories and how varied these might be across different children. Thus, we know little about…

It is unknown if the developmental path of antonym knowledge in deaf children increases continuously with age and correlates with reading comprehension, as it does in hearing children. In the current study we tested 564 students aged 4-18 on a receptive multiple-choice American Sign Language (ASL) antonym test. A subgroup of 138 students aged 7-18…

Purpose: To investigate the longitudinal trajectories of verbal and nonverbal skills in individuals with a history of specific language impairment (SLI) from childhood to adolescence. This study focuses on SLI only and investigates within-participant measures across abilities. Method: Verbal and nonverbal skills were assessed in 242 children with…

Background: It is recognized that children from areas associated with socioeconomic disadvantage are at an increased risk of delayed language development. However, so far research has focused mainly on young children and there has been little investigation into language development in adolescence. Aims: To investigate the language abilities of…

Background: Girls with fragile X syndrome (FXS) have a wide range of cognitive and language abilities. The range of language outcomes experienced by girls with FXS, however, has been relatively unexplored. The purpose of this exploratory study was to examine receptive and expressive language, with a focus on vocabulary and syntax, in a group of…

Up to 16% of students in mainstream secondary schools present with language impairment (LI). As with other learning difficulties, students with LI experience many academic, social, emotional and behavioral problems. Associated presenting behaviors may, however, be masking the primary language impairment. As a result, secondary school students with…

A modified incidental-teaching procedure was used to increase the receptive language skills of two autistic youths with previous institutionalization. Percentage of correct, unprompted object identifications increased when the incidental-teaching package (gestural prompts, behavior-specific praise, and contingent access to lunch-making supplies)…

This study compared judgments of idiom familiarity and transparency by 50 11-year-old children and 50 16-year-old adolescents. Although the children had less familiarity and greater difficulty comprehending the idioms than did adolescents, their transparency judgments were similar. For both groups the easiest idioms were also judged as the most…

From a theoretical viewpoint, the results of the study support the importance of the receptive expressive distinction in considering behavior. The practical implications suggest the importance of assessing receptive functions more directly and support present large-scale remedial procedures for disadvantaged youth in terms of improving and…
