“…In contrast, we agree with those who have limited the word to refer to formal properties rather than to content: States are psychological entities that are short-lived, continuous, and concrete, as opposed to long-lived, discontinuous, and abstract (Cattell, Cattell, & Rhymer, 1947;Fridhandler, 1986;Nesselroade, 1988;Patrick & Zuckerman, 1977;Spielberger, Lushene, & McAdoo, 1977). Thus, states can apply to trait content just as traits can.…”
