We examined the communicative intentions behind parents' deictic gesture use with high-risk infants later diagnosed with autism spectrum disorder (ASD; n = 17), high-risk infants who were not diagnosed with ASD (n = 25), and low-risk infants (n = 28) at 12 months and assessed the extent to which the parental deictic gesture intentions predicted…

We investigated gestures that parents used with 12-, 18-, and 24-month-old infants at high or low risk for autism spectrum disorder (ASD; high-risk diagnosed with ASD: n = 21; high-risk classified as no ASD: n = 34; low-risk classified as no ASD: n = 34). We also examined infant responses to parent gestures and assessed the extent to which parent…

Typically-developing (TD) children frequently refer to objects uniquely in gesture. Parents translate these gestures into words, facilitating children's acquisition of these words (Goldin-Meadow et al. in "Dev Sci" 10(6):778-785, 2007).

The current study examined the relationship between early language ability and autistic-like traits in adulthood, utilising data from 644 participants from a longitudinal study of the general population. Language performance at 2 years was measured with the Language Development Survey (LDS), and at 20 years the participants completed the…
