Virtual Reality-training in Theory of Mind in the Childhood Form of Myotonic Dystrophy Type 1

"Two social scenarios will be used in a virtual environement. Experimenter and subject participate in the scenario as friends of the main character, Nicolas. During the training session, experimenter asks structured questions about participant's awareness of a mental state. In the case of a wrong answer, a feedback-correction is provided via the avatar's thought bubbles. The participant has access to all avatars thought bubbles. In this way, he is able to compare the desires, beliefs or false beliefs of each story character.~Participants included in this condition will also have an eye-tracking assessment before and after the training procedure."

The same two social scenarios are presented to the participant in a story-telling form. Participant has access to thought bubbles via an illustrated book. These trainings will take place in the same number of sessions and took place for a duration equivalent to those used in low immersion Virtual Reality mode. Each training session (EFB, BE, SOFB, ERA, FP, EFP) will be illustrated via visual aids taken from screenshots of the two virtual environments and the target protagonists.
