Autism spectrum disorder (ASD) is a neurodevelopmental condition that includes social-communication deficits and repetitive and stereotypical behaviours (APA 2022). Neurobiological methods of studying ASD are a promising methodology for identifying ASD biomarkers. Mu rhythms (Mu) have the potential to shed light on the socialisation deficits that…

Purpose: The purpose of this mixed methods study was to investigate how teachers in the United States understand and perceive developmental language disorder (DLD). This study used a survey to examine teachers' understanding of DLD and the impact of DLD at school to inform advocacy efforts within the discipline of communication sciences and…

Children with communication disorders present with a range of comorbid conditions. Occasionally one of the comorbid conditions manifests so strongly that the primary condition goes unnoticed by the clinician. This tendency to overlook comorbid health problems in the presence of a disability is referred to as diagnostic overshadowing. This is a…

Purpose: This study focused on whether developmental communication disorders exist in American Sign Language (ASL) and how they might be characterized. ASL studies is an emerging field; educators and clinicians have minimal access to descriptions of communication disorders of the signed modality. Additionally, there are limited resources for…

Cluttering is a rate-based disorder of fluency, the scope of whose diagnostic criteria currently remains unclear. This paper reports preliminary findings from a larger study which aims to determine whether cluttering can be associated with language disturbances as well as motor and rate based ones. Subtests from the Mt Wilga High Level Language…

Research has identified a significant relationship between social, emotional and behavioural difficulties (SEBD) and speech, language and communication difficulties (SLCD). However, little has been published regarding the levels of knowledge and skill that practitioners working with pupils experiencing SEBD have in this important area, nor how…

We tested whether developmental coordination disorder (DCD) and mixed receptive expressive language disorder (RELD) are valid diagnoses by assessing whether they are separated from each other, from other childhood disorders, and from normality by natural boundaries termed zones of rarity. Standardized measures of intelligence, language, motor…

Children adopted from abroad at older ages have unique speech and language-learning issues. At adoption, the impact of longer stays in orphanages with their associated lack of enrichment, nutrition, and healthcare is more pronounced. After adoption, the children begin school in a new language soon after arriving home. These children quickly lose…

Growing evidence suggests that, as a group, many internationally adopted children catch up to their peers in terms of their language development by the time they reach their school-age years. Although this appears to be particularly true for children adopted during the first few years of life, it is not true for all internationally adopted…

Although sharing many of the identified difficulties associated with autism, Asperger's syndrome (AS) is widely believed to differ in the domain of linguistic deficit. While researchers may disagree in detail about the language and communication performance of pupils with Asperger's syndrome, there seems to be general consensus that such…

Fifty preschool children were administered a screening test for communication disorders under two conditions (traditional pencil and paper format and a computer-managed version). It was found that the computer-managed screening test yielded satisfactory agreement for the language sections. Results of the articulation section of the screening test…

A screening method for distinguishing speech and language disordered children (2 to 15 years old) with and without psychiatric disorders (N=256) involved cutoff scores for an easily administered parent and teacher behavior rating questionnaire. (CL)

This article describes two studies that examined the concurrent and predictive validity of the Communication and Symbolic Behavior Scales Developmental Profile (CSBS DP), a measure for identifying children less than 24 months old who are at risk for communication disorders. Findings support the use of prelinguistic predictors and the important…

A naturalistic probe of early language content was administered to 31 normally developing preschool children. The productivity of 3 different strategies for eliciting 27 content categories was tested and the efficiency of the probe technique compared with analysis of language samples. Results suggest this nonstandardized, criterion-referenced…

This study surveyed routine language screening practices for infants and toddlers of 41 physicians in an urban and surrounding rural area. Findings indicated that all physician offices screened for language development with some using the Denver Developmental Scale and others using informal tools. Findings are discussed in the context of the…
