Relations between verb factivity and first-order and second-order false belief understanding: Evidence from Mandarin-speaking typically developing children and children with autism spectrum disorders.

This study examined relations between verb factivity and first-order and second-order FB reasoning in 156 four- to seven-year-old typically developing (TD) Mandarin-speaking children, and in 17 children with autism spectrum disorders (ASD) and 17 TD matched controls. Children's understanding of a factive zhīdào 'know', a non-factive juédé 'think' and a counter-factive jiǎzhuāng 'pretend' was assessed by a truth value judgement task. For TD children, zhīdào 'know' (factive) significantly predicted their first-order and second-order FB performances, and jiǎzhuāng 'pretend' (counter-factive) significantly predicted their first-order FB performance. For autistic children, they performed significantly poorer than their TD counterparts on complementation, verb factivity, first-order and second-order FB, and their first-order FB performance was significantly related to jiǎzhuāng 'pretend' (counter-factive). The findings suggest that verb factivity relates to both first-order and second-order FB, and verbs differing in factuality and mental state status contribute differently to ToM development.
