The following models were compared: 1 + (1 | ID) vs 1 + Session + (1|ID), 1 + Group + (1 | ID) vs 1 + Group + Group: Session + (1|ID), 1 + Session + (1 | ID) vs 1 + Group + Group: Session + (1|ID). For models without and with individual differences, the number parameters were 7 and 12, and degrees of freedom were 4 and 8, respectively. Degrees of freedom for comparison between models were 5
