EV: Eigenvalue. FL: Factorial loads. % σ2: percentage of explained variance. (s): Seconds. Kaiser Meyer Olkin = 0.504. Bartlett’s Sphericity test, χ2(6) = 40.565, p = 0.0001. aFactor scores are the mean of standardised regression coefficients ± their error standard of the mean. bStatistical significance corresponds to an analysis of variance comparing the factorial scores between control (CON) and stress (CUS) groups (see main text for details).
