Do autistic people have lower mental ages?

Not necessarily. Autism involves different cognitive patterns—detail focus, pattern recognition, literal thinking. These don't align with age-based norms but aren't less mature.

How do mental age tests work for autistic people?

Poorly. Tests assume neurotypical reasoning and social norms. Autistic individuals may outperform on abstract reasoning while appearing younger on social judgment items.
