We also observed the expected relationships between autistic traits and mental health questionnaire measures. For example, autistic trait scores were negatively correlated with cognitive empathy, but not affective empathy. These findings support the validity of the questionnaire measures.
However, we found strong evidence for the absence of relationships between autistic trait scores and both self-bias (BF01 = 32.13) and social basis function use (BF01 = 7.04), indicating preserved self–other integration during social decision-making.
