There is a great deal of variability in how families read and interact with picture books. To understand why reading practices may (or may not) relate to language outcomes, a necessary step to understand what occurs in the home. The goal of this work is to better understand the frequency and nature of picture book reading at home with children…

Children learn math concepts long before they enter school. Across all cultures, children are exposed to number and spatial language to varying degrees during everyday home routines. Yet most studies of math talk occur in the lab and target non-Hispanic, English-speaking families. We expanded inquiry to the spontaneous math language (i.e., number…

Attentional difficulties are evident in children with autism spectrum disorder (ASD). Accordingly, mothers of children with ASD may modify communication to direct their child's attention, and this pattern may generalize to later-born children. This study examined patterns of child-directed communication in 11 mothers of 18-month-old toddlers at…

The Mandarin resultative verb compound (RVC; e.g., "tui dao" "push fall" and "pa shang" "climb ascend") encodes complex events composed of an initiating action and resulting activity or state. This study investigated when Mandarin-speaking children acquired this language-specific device. Specifically, we…

The present study examined continuity/discontinuity and stability/instability of noun and verb production measures in 30 child-mother dyads observed at 16 and 20 months, and predictive relations with the acquisition of nouns and verbs at 24 months. Children exhibited significant discontinuity and robust stability in the frequency of nouns and…

Joint attention between hearing children and their caregivers is typically achieved when the adult provides spoken, auditory linguistic input that relates to the child's current visual focus of attention. Deaf children interacting through sign language must learn to continually switch visual attention between people and objects in order to achieve…

Generic noun phrases, or generics, refer to abstract categories ("Dogs" bark) rather than particular individuals ("Those dogs" bark). Study 1 investigated how parents use gestures in association with generic versus particular reference during naturalistic interactions with their 2- and 3-year-old children. Parents provided…

Purpose: The current study used an intervention design to test the hypothesis that parent input sentences with diverse lexical noun phrase (NP) subjects would accelerate growth in children's sentence diversity. Method: Child growth in third person sentence diversity was modeled from 21-30 months (n = 38) in conversational language samples obtained…

Young infants can learn statistical regularities and patterns in sequences of events. Studies have demonstrated a relationship between early sequence learning skills and later development of cognitive and language skills. We investigated the relation between infants' visual response speed to novel event sequences, and their later receptive and…
