Hi Daniella, I wonder if any insights were gathered on the specifics of mirroring between genders, specifically whether there is a causality between the gender of the two involved persons and the quality of the mirroring. eg would a man typically better "mirror" with a man than with a woman. Both the strength and the accuracy of the mirroring could be relevant. 
Would be grateful for any info you may have. Thank you!
