Apr 07, 20 psychology definition of configural learning. However, metric invariance is necessary to infer that the construct has the same meaning, because it provides evidence about the equality of validity coefficients. Such comparisons, however, cannot be made until validity evidence has been collected to support the use of an achievement goal orientation instrument for that purpose.
