Abstract
Misophonia is characterized by a lowered tolerance coupled with a defensive reaction to socially-related auditory stimuli. Given the current gap in standardized diagnosis and treatment methods, there is a critical need to understand the processes underlying aversive auditory processing in misophonia. To address this, we used EEG to measure event-related potentials (ERPs), analyzing N1 (the registration of sensory input allocation of pre-attention) and P2 (the classification of stimuli of pre-attention) amplitudes. We examined whether misophonia triggers paired with either mechanical vs. social visual cues elicit attention allocation and/or habituation effects in comparison to autism spectrum disorder, and typically developing adults. Participants with misophonia displayed greater registration of sensory input (N1) and decreased classification of stimuli (P2) to first social cues. For the second cues, there was no significant display of context specific habituation to second cues despite source differences. These results suggest that adults with misophonia have an exaggerated tendency to focus on social cues, while reducing attention towards the social cues when firstly registering sensory inputs, possibly as a coping mechanism.
