International audience ; Auditory hallucinations (AH) can be found both in clinical samples (i.e. schizophrenia) and in the general population. To further understand the continuities and discontinues in terms of mechanisms underlying AH, in our study, we sought to better understand the top-down and bottom-up processes behind this phenomenon in both samples. Indeed, Waters et al. (2012) and other recent models, have highlighted the importance of considering the interplay between top-down (e.g., signal detection) and bottom-down (e.g., sensory information) processes. Participants in both samples will be recruited based on the scores on auditory hallucinations (-proneness). All the participants will complete two versions of the auditory Signal Detection Task (aSDT), the Tone Matching Task (TMT), and questionnaires measuring hallucination proneness and creative experiences. For the aSDT, two noises will be used, one with only human-speech frequencies, and the other one without these frequencies. We hypothesize that participants (clinical and non-clinical) with AH (or proneness) will make more false alarms and will have a decision bias on the aSDT only for trials with the noise containing human-speech frequencies. Patients with schizophrenia will have poorer performances in the TMT than the healthy volunteer. The results presented during this meeting will be preliminary and only on the healthy volunteer. This study will help us to better understand the continuities and discontinues in terms of mechanisms underlying AH and their interactions, in both clinical and non-clinical samples. |
