To isolate effects of radical positions, four types of pseudocharacters were created in which the constituent radicals appeared in positions varying in probability of occurrence, that is, Unique, Dominant,…

This article proposes a generalized distance discriminating method for test with polytomous response (GDD-P). The new method is the polytomous extension of an item response theory (IRT)-based cognitive diagnostic method, which can identify examinees' ideal response patterns (IRPs) based on a generalized distance index. The similarities between…

Autism spectrum disorder (ASD) is a disorder with high levels of co-morbidities. The Developmental, Dimensional and Diagnostic Interview (3Di) is a relatively new instrument designed to provide dimensional as well as categorical assessment of autistic behaviours among children with normal intelligence.

Previous work leaves open the question of whether children with autism spectrum disorders aged 6-12?years have delay in producing gestures compared to their typically developing peers. This study examined gestural production among school-aged children in a naturalistic context and how their gestures are semantically related to the accompanying…

Previous studies showed that the anterior cingulate cortex (ACC) is activated when individuals engage in attention and inhibitory control tasks. The present study examined whether ACC activity is associated with behavioral performance of the two tasks. Twenty normal and 20 children with autism spectrum disorders (ASDs) were subjected to…

The present study aimed to investigate the contribution of oral language skills, linguistic skills, and transcription skills to Chinese written composition among Grade 4 students in Hong Kong.
