Sensory-motor Interactions in the Perception of Vowels: a Study in Repetition - Suppression (NEUROPHONE)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03102983
Recruitment Status : Completed
First Posted : April 6, 2017
Last Update Posted : October 10, 2018
Information provided by (Responsible Party):
University Hospital, Grenoble

Brief Summary:
The aim of our study is to show by fMRI the involvement of the motor system in the perception of speech, and more particularly how this implication is modulated by the degree of prototypicity of the stimuli.

Condition or disease Intervention/treatment Phase
Healthy Other: MRI functional Not Applicable

Detailed Description:

Each participant will undergo two visits:

Phase 1: The Gipsa-Lab Laboratory's Department of Speech and Cognition. This first visit will make it possible to make recordings of their vowel productions and to verify that the participants correspond to the criteria necessary for the study (passing the Edinburgh manual laterality test and auditory thresholds checked using a " An audiogram). It will also be an opportunity to provide them with the consent documents and the fact sheet, which will give them time to read it before the MRI exam. The duration of this first visit will be approximately 1 hour.

Phase 2: fMRI review in the 3Tesla MRI Unit at the Grenoble University Hospital Center. Participants will first undergo a medical examination in order to verify their absence of contraindication to the MRI examination. At the end of this medical examination, the consent of participation will be signed. The participants will then be able to carry out the MRI examination for a duration of about 1h15, then the behavioral judgment test of perceptual distance. The total duration of this second visit will be approximately 1h45.
