There are still no straightforward answers as to whether understanding one's own emotions is impaired in autism spectrum disorder (ASD). This study evaluated the perception of one's own different emotions, based on the relevant section of the Autism Diagnostic Observation Schedule Module 3 test. Forty boys, aged 8-11 years, 20 diagnosed with ASD (IQ = 85) and 20 typically developing children were included. Description of events that elicited specific emotions in ASD was characterized by more "odd" statements and "no responses" and less use of content related to "social situations", "interpersonal" and "self-awareness". More "no responses" and odd statements were associated with the severity of ASD symptoms. Clinicians should be aware of these differentiating factors during the diagnostic process of ASD.
