Research Findings: Measuring toddlers' cortisol levels both in childcare and at home and their relation to child- and childcare-related factors may help to identify stress-inducing childcare practices and children who are more vulnerable to stress in childcare. Accordingly, toddlers' (n = 320, 51.2% female, mean age = 26.8 months) cortisol levels…

Family routines provide young children with predictable, repeatable, and functional contexts for learning about the world. Participating in family routines is a critical pathway by which all children learn. While the use of family routines in caregiver-implemented interventions (CIIs) is supported by theories, research, and recommended practices,…

Children learn the words of their native language(s) from interactions with their caregivers. Although previous research has found that the language children hear during those interactions predicts vocabulary outcomes, few studies have investigated how qualitative features of social interactions work together to affect children's vocabulary…

Within a language, there is considerable variation in the pronunciations of words owing to social factors like age, gender, nationality, and race. In the present study, we investigate whether toddlers link social and linguistic variation during word learning. In Experiment 1, 24- to 26-month-old toddlers were exposed to two talkers whose front…

Purpose: Disfluencies associated with stuttering generally occur in the initial position of words. This study reviews data from a school-age child with an atypical stuttering profile consisting predominantly of word-final disfluencies (WFDs). Our primary goals were to identify patterns in overt features of WFDs and to extend our understanding of…
