Lastly, our findings have implications for the hypothesis that auditory hallucinations involve abnormalities of language-related, left-hemisphere function (e.g., Badcock & Hugdahl, 2012). Although N1 sink reduction was greatest for words and over left inferior-parietal sites where N1 sink was largest, the lack of a significant interaction involving group and hemisphere and/or task does not provide statistical support for this hypothesis. Rather, a bilateral inferior-parietal N1 sink reduction in hallucinators was present to both words and faces.
