In the study by Baron-Cohen et al. (1997) on autism in adults, what was the primary methodological reason for including a comparison group of participants diagnosed with Tourette's Syndrome?
To prove that the Eyes Task measures general non-verbal intelligence rather than theory of mind, as both clinical groups were expected to show identical cognitive profiles.
To rule out the possibility that any observed deficits on the Eyes Task were simply due to having a childhood-onset, organically-based neurodevelopmental disorder.
To act as a baseline group for basic facial and emotion recognition, as participants with Tourette's Syndrome do not experience any social or communication difficulties.
To control for gender imbalances across the experimental groups by providing an equal ratio of male and female participants in the clinical control condition.
