Infants show shifting patterns of visual engagement to faces over the first years of life. To explore the adaptive implications of this engagement, we collected eye-tracking measures on cross-sectional samples of 10-25-month-old typically developing toddlers (TD;N = 28) and those with autism spectrum disorder (ASD;N = 54). Concurrent language…

Background and Aims: This longitudinal study investigated the language skills, phonological working memory and lexical-tone perception of Mandarin-speaking late-talkers (LTs) and those with typical language development (TLD) at 27 months, while also examining their connections with novel word-referent mapping (W-R mapping) through eye-tracking at…

Purpose: Previous research shows that shared storybook reading interactions can function as effective speech and language interventions for young children, helping to improve a variety of skills--including word-learning. This study sought to investigate the potential benefits of elaboration of new words during a single storybook reading with…

Efficient visual exploration in infancy is essential for cognitive and language development. It allows infants to participate in social interactions by attending to faces and learning about objects of interest. Visual scanning of scenes depends on a number of factors, and early differences in efficiency are likely contributing to differences in…

Before infants produce words, they can discriminate changes in motion event components such as manner (how an action is performed) and path (trajectory of an action). Individual differences in nonlinguistic event categorization are related to children's later verb comprehension (Konishi, Stahl, Golinkoff, & Hirsh-Pasek, 2016). We asked: (a) Do…

Purpose: The purpose of this study was to understand how joint attention and sensory-regulatory features are related in early childhood and predict language and social-communication outcomes in preschool in order to build mechanistic theories that can inform early intervention directed at improving these outcomes. Method: Cross-lagged panel…

Purpose: We examined receptive verb knowledge in 22- to 24-month-old toddlers with a dynamic video eye-tracking test. The primary goal of the study was to examine the utility of eye-gaze measures that are commonly used to study noun knowledge for studying verb knowledge. Method: Forty typically developing toddlers participated. They viewed 2…

This research addresses the challenges of assessing receptive language abilities in minimally verbal children with autism spectrum disorder by comparing several adapted measurement tools: a standardized direct assessment of receptive vocabulary (i.e. Peabody Picture Vocabulary Test-4); caregiver report measures including scores on the Vineland-II…

Purpose: Comparing children's skills across and within domains of development has become a standard in providing early intervention services. Profiling a child's strengths and challenges can help in making decisions regarding eligibility, diagnosis, and intervention. Profiling is particularly important for children who are not yet talking, due to…
