The niche-picking principle posits that the reciprocal exchange between people and their environments-person-environment transaction-serves to maintain trait continuity, thereby preserving rank-order stability of trait differences. To date, however, no longitudinal twin study has directly tested whether reciprocal effects between people and their environments contribute to trait continuity in middle and older adulthood.
