Dependent variable: Speech imitation (SI).
This table shows the results of the stepwise multiple regression MLR 1. The dependent variable was the speech imitation ability (SI). The independent variables were the working memory (sometimes also called auditory short term memory) (WM), the singing ability (SA) and the education score (E).
