Results

We investigated whether adults with autism spectrum disorder (ASD) intentionally suppress memory compared with typically developed adults (TD) using think/ no think task that is categorized into meta-cognition task. Eighteen typically developed adults and 16 adults with autism spectrum disorder participated in this study. The results showed that no difference between ASD and TD about the ability of intentionally suppressing the memory was observed (p = 0.8869).
