The theoretical and mathematical analyses indicate that this model makes novel predictions about the way in which test-retest correlations are structured across a wide range of ages and test-retest intervals.
Personality psychologists, for example, have focused on the stability of individual differences in person- ality traits, as commonly quantified by test-retest correlations (see Robins, Fraley, Roberts, & Trzesniewski, 2001).
Left: A histogram of test-retest correlations that have been observed in adulthood for the Big Five personality traits.
Right: Curves that fit these data but have dramatically different implications for the test-retest correlations over increasing test-retest intervals (in years).
Specifically, the predicted test-retest correlation approaches zero as the test-retest interval gets larger.
