Before an infant can learn the link between a word and an object by following a pointing gesture, Professor Nancy Rader’s team has found that infants can learn this association through ‘show gestures’. Show gestures entail bringing an object towards the child and rotating it, while synchronizing the movements with speech. While the effect of show gestures decreases with age during childhood, Rader and her colleagues have found that non-verbal children on the autism spectrum are very sensitive to this information, performing as well in learning words as age-matched typically-developing children.
