In particular, cognitive shifting in executive function is deeply related to stereotyped behavior in ASD. Previous investigations have clarified that the lateral prefrontal cortex is involved in cognitive shifting when flexible changes in attention were needed. However, a few studies have revealed a direct association between cognitive shifting tasks and lateral prefrontal cortex activity in children with ASD. We examined cognitive shifting in 7-to 12-year-old children with ASD and typically developing children using the dimensional change card sort task. In addition, using near-infrared spectroscopy, we examined prefrontal brain activity in conjunction with cognitive shifting. The autistic children provided fewer correct answers and slower reaction times in the task than typically developing children. Fur-thermore, the autistic children displayed a...

Researchers have found pragmatic language deficits in children and adults with autism spectrum disorder (ASD) (Surian et al., 1996; Paul et al., 2009). However, few studies focused on the development of pragmatic language understanding in children with ASD. Objectives: We examined how the performance of children with ASD and typically developing (TD) children changed across ages and explored which conversational rules (i.e., Gricean maxims) children with ASD had difficulty understanding by using the Japanese version of Conversation Violation Test (CVT-J). Methods: Participants were 13 children with ASD (mean age: 6 years 10 months; range: 5 years 2 months to 9 years 7 months) and 13 TD children (mean age: 6 years 9 months; range: 5 years 1 month to 9 years 5 months), individually matched on chronological age and sex and group-matched o...

They developed a nonverbal dimensional change card sorting task, which indexed the development of executive function. Three pairs of mother and offspring chimpanzees and 30 typically developed 5-year-old children were presented with 2 target stimuli and a test stimulus comprising 2 dimensions (size and shape) on a display; they were required to sort the test stimulus according to 1 dimension (e.g., shape). After 5 consecutive correct trials, the participants had to sort the test stimulus according to the other dimension (e.g., size). The results showed that the chimpanzees often failed to sort the test stimuli according to the first and reversed dimensions. On the other hand, the children were correctly able to use both dimensions. These results indicate that chimpanzees may have less developed executive skills than children.

There is evidence that young preschoolers' difficulty on this task is caused by conflicting first-phase cues for the target cards, but these findings have not been replicated. We examined whether conflicting first-phase cues for the target cards caused young children's (N=44, M=43.3 mo., SD=2.5) perseveration errors. In the present experiment, we compared a No Conflict condition, in which children did not encounter conflicting first-phase cues, with a Conflict condition (standard task). Analysis indicated that children in the No Conflict condition showed significantly better performance than those in the Conflict condition. This result suggested that children's perseveration errors on the task were, in part, caused by the conflicting first-phase cues for the target cards.

The present study explored whether children who committed perseverative errors in the social context also committed perseverative errors in the standard DCCS task. Three- and 4-year-old children were given the standard DCCS and the observation version of the DCCS, and the relationship between them was examined. The results showed that the correlation between these two tasks was significant. Furthermore, 4-year-old children displayed more difficulty in the observation version than in the standard DCCS, whereas 3-year-olds did not. The results are discussed in terms of the development of inhibitory control and social cognition.
