Children who are deaf and hard of hearing (DHH) and learning to listen and speak begin developing spoken language skills later than their peers with typical hearing (TH). Consequently, it is well-documented that those children who are DHH lag their TH peers in spoken vocabulary development during their earliest years and on average, those lags…

Behavior analysts frequently use the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) to assess the language and social skills of children with autism in everyday practice and in research. Despite the widespread use of the VB-MAPP, its psychometric characteristics have not been extensively investigated. To provide information…

Background: When mathematical knowledge is expressed in general language, it is called verbalized mathematics. Previous studies on verbalized mathematics typically paid attention to mathematical vocabulary or educational practice. However, these studies did not exclude the role of symbolic mathematics ability, and almost no research has focused on…

This study aims to examine the relationship between school maturity levels and speech and language development of children receiving preschool education. The correlational survey models was used to determine these relationships. The sample of the study consists of 44 boys and 58 girls who are studying in public schools in Meram district of Konya…

The present study aims to examine the Executive Function (EF) skills of preschool-aged children who are deaf and hard of hearing (DHH), and explore the variables related to their EF skills. Thirty preschoolers who were DHH and an additional 35 preschoolers with typical hearing were recruited. All DHH use spoken language as their communication…

Purpose: A recent approach to identifying early markers of risk for autism spectrum disorder (ASD) has been to study infants who have an older sibling with ASD. These infants are at heightened risk (HR) for ASD and for other developmental difficulties, and even those who do not receive an eventual ASD diagnosis manifest a high degree of…

Background: Early intervention for children identified as late talkers (LTs) at the age of 24 months is still a controversial issue in research and clinical routine. Previous studies have shown inconsistent results regarding predictors of early lexical deficits on school-age outcomes of late-talking toddlers. Methods: In a five-wave follow-up…

Purpose: Verbal short-term memory (STM) and working memory (WM) skills predict speech and language outcomes in children with cochlear implants (CIs) even after conventional demographic, device, and medical factors are taken into account. However, prior research has focused on single end point outcomes as opposed to the longitudinal process of…

Background: Mothers facilitate their young hearing children's word learning by making reference explicit for novel words through physical designation (e.g., with deictic gestures) and by isolating words in simple syntactic frames. As children's language skills develop, such modifications decrease. Less is known about hearing mothers' support to…

In this study we examined early motor, vocal, and communicative development in a group of younger siblings of children diagnosed with autism (Infant Siblings). Infant Siblings and no-risk comparison later-born infants were videotaped at home with a primary caregiver each month from 5 to 14 months, with follow-up at 18 months. As a group, Infant…
