Research on repetition suppression suggests that neural correlates of prediction errors (PE) in autism spectrum disorder (ASD) might be domain-specific with increased attenuations for faces compared to objects. Contrastingly, research assessing mismatch negativity in attention-deficit/hyperactivity disorder (ADHD) indicates a domain-general attenuation of PE. Therefore, we captured neural correlates of PE to colours and emotions in adults with ADHD or ASD to assess domain-specificity of PE attenuations. We extracted participant-unspecific precision-weighted PE and prediction strength (PS) for emotions and colours of presented faces separately using a generative model, specifically a Hierarchical Gaussian Filter (HGF). While we found neural correlates of colour precision-weighted PE and PS as well as emotion PS in the pooled sample regardless of diagnostic group, we did not find any differences in neural correlates of emotion or colour precision-weighted PE or PS between our groups. This null finding indicates intact neural correlates of precision-weighted PE in ASD and ADHD for both colours and emotions.
