The production of specific mental state terms types and functions by caregivers and their TD children and caregivers and their children with ASD were assessed in two contexts: a parent's story-telling task and a child's story-telling task. Caregivers of children with ASD produced less causal talk and proportionally less desire and cognitive talk than did caregivers of TD children. When focusing only on variation in our ASD sample, caregivers' and children's production of different mental state references varied with context and were predicted by different child characteristics (i.e., theory of mind, autism severity, language level). We conclude that caregivers are likely adjusting different aspects of mental state input depending on different aspects of child development although these adjustments may not always be optimal.
