The home environment is a significant factor that greatly influences the motor development of children. This study aims to examine the cultural adaptation validity and reliability of the Affordances in the Home Environment for Motor Development (AHEMD-SR) for Turkish children aged 18--42 months. The study included 103 Turkish children (mean age =…

Children actively and selectively transmit information to others based on the type of information and the context during learning. Four- to 7-year-old children preferentially transmit generalizable information in teaching-like contexts. Although 2-year-old children are able to distinguish between generalizable and non-generalizable information, it…

Purpose: The present study explored the extent to which early prelinguistic communication skills predict expressive language in toddlers with autistic siblings (Sibs-autism), who are known to be at high likelihood for autism and language disorder, and a comparison group of toddlers with non-autistic older siblings (Sibs-NA). Method: Participants…

Purpose: The Language ENvironment Analysis (LENA) technology uses automated speech processing (ASP) algorithms to estimate counts such as total adult words and child vocalizations, which helps understand children's early language environment. This ASP has been validated in North American English and other languages in predominantly monolingual…

This longitudinal study - conducted in the Midwestern United States - examines the child-level factors that promote Spanish-English bilingual toddlers' (n = 47; M[subscript age] = 18.80 months; SD[subscript age] = 0.57) productive vocabulary skills from 18 to 30 months of age. At 6-month intervals, caregivers reported on toddlers' Spanish and…

Purpose: The purpose of this study is to determine if 2.5-year-olds with language delay would learn verbs ("spill") when presented with varying syntactic structure ("The woman is spilling the milk"/"The milk is spilling"; "milk" = patient or theme) in a therapeutic context. Children with language delay have…

Shared book reading is a well-established intervention for promoting child language and early development. Although most shared reading interventions have included children 3 years of age and older, recent evidence demonstrates dialogic strategies can be adapted for parents of infants and toddlers. The current study examines gains in parent…

Verb-marking errors such as "she play football" and "daddy singing" are a hallmark feature of English-speaking children's speech. We investigated the proposal that these errors are input-driven errors of commission arising from the high relative frequency of subject + unmarked verb sequences in well-formed child-directed…

Research Findings: Temperament, which can be assessed as early as 3 months, is associated with school readiness and later academic achievement in children born full term. Although children born preterm demonstrate a dysregulated temperament and are at significant risk for lower school readiness, we found no studies investigating whether early…

Purpose: This study aims to help researchers design observational measurement systems that yield sufficiently stable scores for estimating caregiver talk among caregivers of infant siblings of autistic and non-autistic children. Stable estimates minimize error introduced by facets of the measurement system, such as variability between coders or…

This study examined patterns of verbal responsiveness in parents of toddlers (M[subscript age] = 20 months) later identified with autism (n = 121), developmental delay (n = 46), or typical development (n = 44) during an hourlong home observation. Parent verbal responsiveness (PVR) was compared using MANOVA across groups and by child expressive…

There has been a major international focus on the education and care of toddlers. To date, empirical studies on adults' interactions in play with toddlers have focussed on the proximity of teachers, teachers' affective responses, and joint attention between adults and children in play. However, less attention has been given to the role of two…

The 2020 Dietary Guidelines for Americans now include recommendations for infants and toddlers. Extension educators can use these expanded guidelines to provide feeding recommendations for caregivers of infants/toddlers. The purpose of this study was to explore 1) the infant and toddler feeding topics that Extension educators discuss with…

Sensory features are included in the diagnostic criteria of autism spectrum disorder, and sensory responsiveness may produce "cascading effects" on later development. However, the relation between early sensory profiles and later skills has yet to be defined. This study aims to characterize sensory subgroups in 116 toddlers at elevated…

Screening for autism in childhood has been advocated as a part of standard care. Challenges exist with screening implementation and performance of screening tools in clinical practice. This study aimed to examine the validity and feasibility of using the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F) for screening…
