Structural equation model of the interference effect in Stroop task. N = 70. The standardized maximum likelihood parameter estimates are shown. The error variances (e1, e2, and e3) indicate the amount of unexplained variance. Thus, for the observed variable of Balance Usage, Balanced Proficiency and Interference Effect, R2 = (1 - error variance). *p < 0.05, **p < 0.01.
