| Research Abstract |
1. Weak Central Coherence and Executive Function in children with Autism Spectrum Disorder We investigated both behavioral and neurological aspects of weak central coherence (WCC) in situations similar to those encountered during everyday life. To investigate WCC in situations similar to everyday life, we used large 9 pictures (W80 × H64 cm). Participants were 13 children with ASD and15 typically developing (TD) children. Participantsexplained about each picture. We analyzed verbal responses and also used near-infrared spectroscopy (NIRS) to assess brain activation in the lateral prefrontal cortex (PFC) as the participant explained the picture. ASD children showed lower activation of the right lateral PFC than TD children, while also failing to recognize semantic coherence, suggesting that weak coherence is related to right lateral PFC functioning.
2. The Executive Function Strategy Education Program (ESEP) andthe Central Coherence Strategy Education Program (CSEP) for Children with Autism Spectrum Disorder We made the Executive Function Strategy Education Program (ESEP) to train executive function in children with ASD, and the Central Coherence Strategy Education Program (CSEP) to train central coherence in children with ASD. We used the ESEP to train 7 ASD children (ESEP group), and used the CSEP to train 9 ASD children (CSEP group). The effect of the program was measured by DN-CAS (Das-Naglieri Cognitive Assessment System). In ESEP group, the scores of “Simultaneous” and “Planning” were higher than before the training, but the score of “Attention” and “Successive” were not significant. In CSEP group, the score of “Planning” was higher than before the training. In both group, full scoreswere significantly increased.
