A. The probability for ToM model (98.2%) was higher than for the fixed strategy model for controls, while the fixed strategy model was dominant (78.6%) in individuals with ASC.

B. Diagnosis measurement scores; Autism Diagnostic Interview-Revised (ADI-R) and Asperger Syndrome and High-functioning Autism Diagnostic Interview (ASDI), were significantly higher for the ASC participants whose behaviour fit better with the fixed strategy model (n=12) than those showing a better fit with the ToM model (n=5).

C. In the ASC group, the greater expectation of recursive belief inference, the severer autism symptomatology (n=14, r=−0.52, p=0.055), as measured by the sum of scores on the ADI-R and the ASDI.

D. The estimated forgetting parameter for the ASC group (mean ± std=0.57 ± 0.19) was significantly higher than that for the control group (0.93 ± 0.13) (p<0.1e-6).

E. The estimated sophistication for the individuals with autism showed significant positive correlation with individual IQ scores (the left panel: n=17, r=0.54, p=0.026), while there was no correlation for the control participants (the right panel: n=17, r=0.02).
