Intra-group comparison between the times T0 and T2. Trend of STAI-Y and oxyhemoglobinic saturation between the beginning and the end of the session in the 20 patients of the MG and in the CG. STAI-Y1 State-Trait Anxiety Inventory—y form, TO time at the start of the session, T1 time during the session, T2 time at the end of the session, STAI-y State-Trait Anxiety Inventory—y form, TO time at the start of the session, T1 time during the session, T2 time at the end of the session. (a) MUSIC THERAPY GROUP. Intra-group comparison between T0 and T2 times regarding the variation of oxyhemoglobin saturation and STAY-Y. (b) CONTROL GROUP. Intra-group comparison between T0 and T2 times regarding the variation of oxyhemoglobin saturation and STAY-Y. *p < 0.050.

For those who stopped searching, Observe subjects showed significant triplet-type effects in the beginning of the transfer session which did not differ from those found for Respond subjects. For those who continued to search, expression of learning was impaired from the start of the transfer session for Observe but not Respond subjects.

Those who observed the 1st session showed no significant triplet-type effect in the 1st block of the 2nd session whereas those who responded to the 1st session showed significant triplet-type effects in the 1st block of the 2nd session. There was therefore no evidence for perceptual learning in Experiment 1

Example ADC coded signal of four expressions from the best volunteer. (a) Happiness signal of the first session signaling start,holding,go-back and stopping gesture. (b) Anger signal of the first session signaling start, holding, go-back and stopping gesture. (c) Surprise signal of the first session signaling start, holding, go-back and stopping gesture. (d) Blinking signal of the first session signaling start, holding, go-back and stopping gesture.
