This article compares the claims of rule- and constraint-based accounts of three seemingly distinct error patterns, namely, Deaffrication, Consonant Harmony and Assibilation, in the sound system of a child with a phonological delay. It is argued that these error patterns are not separate problems, but rather are symptoms of a larger conspiracy to…

Toddlers who are "late talkers" demonstrate reduced expressive vocabulary in the absence of physical, social, cognitive, or sensory impairment; they are usually identified at age 2, when they produce fewer than 50 words and do not combine words (Rescorla, 1989). This study analyzed spontaneous language samples of 10 late talking toddlers and 11…

Previous work has shown that preterm infants are at higher risk for cognitive/language delays than full-term infants. Recent studies, focusing on prosody (i.e. rhythm, intonation), have suggested that prosodic perception development in preterms is indexed by maturational rather than postnatal/listening age. However, because prosody is heard…

This article describes the development and validation of the Developmental Snapshot, a 52-item parent questionnaire on child language and vocal communication development that can be administered monthly and scored automatically. The Snapshot was created to provide an easily administered monthly progress monitoring tool that enables parents to…

Background: Several studies in recent years have indicated a link between socio-economic status (SES) of families and children's language development, including studies that have measured children's language through formal standardized test procedures. High numbers of children with low performance have been found in lower socio-economic groups in…

The effect of word-level variables on expressive phonology has not been widely studied, although the properties of words likely bear on the emergence of sound structure (Stoel-Gammon, 2011). Eight preschoolers, diagnosed with phonological delay, were assigned to treatment to experimentally induce gains in expressive phonology. Erred sounds were…

Individuals with autism spectrum disorders have impairments in language acquisition, but the underlying mechanism of these deficits is poorly understood. Implicit learning is potentially relevant to language development, particularly in speech segmentation, which relies on sensitivity to transitional probabilities between speech sounds. This study…

The investigators compared two techniques for teaching expressive vocabulary to late talkers: modeling with an expectant pause and modeling with an evoked child production. They also explored the influence of neighborhood density on children's real word learning. Three late talkers (ages 25-33 months) received two alternating vocabulary treatments…

Purpose: There is general consensus that the ability to repeat nonsense words is related to vocabulary size in young children, but there is considerable debate about the nature of the relationship and the mechanisms that underlie it. Research with adults has proposed a shared neural substrate for nonword repetition (NWR) and language production,…

The Social Attention and Communication Study involved the successful implementation of developmental surveillance of the early markers of autism spectrum disorders in a community-based setting. The objective in the current study was to determine the most discriminating and predictive markers of autism spectrum disorders used in the Social…

This study investigates whether distinct neurodevelopmental disorders show distinct patterns of impairments in particular grammatical abilities and the relation of those grammatical patterns to general language delays and intellectual disabilities. We studied two disorders (autism and Williams syndrome [WS]) and two distinct properties (Principle…

The importance of parent-child interaction (PCI) for language development has been well established. This has led many speech and language therapy (SLT) interventions to focus on modifying PCI as a means to improving children's early language delay. However, the success of such programs is mixed. The current review compares PCI, observed in…

This study examined the extent to which receptive and productive vocabulary between ages 12 and 18 months predicted language skills at age 24 months in children born with family risk for dyslexia (FR) and a control group born without that risk. The aim was to identify possible markers of early language delay. The authors monitored vocabulary…

Support for baby signing (BS) with hearing infants tends to converge toward three camps or positions. Those who advocate BS to advance infant language, literacy, behavioral, and cognitive development rely heavily on anecdotal evidence and social media to support their claims. Those who advocate BS as an introduction to another language, such as…

Aim: The aim of this study was to characterize the auditory brainstem responses (ABRs) of young children with suspected autism spectrum disorders (ASDs) and compare them with the ABRs of children with language delay and with clinical norms. Method: The ABRs of 26 children with suspected ASDs (21 males, five females; mean age 32.5 mo) and an age-…
