 As the person experiences situations that contain different psychological features, different [cognitive-affective units] and their characteristic interrelationships become activated in relation to these features. Consequently, the activation of [cognitive-affective units] changes from one time to another and from one situation to another…Although cognitions and affects that are activated at a given time change, how they change, that is, the sequence and pattern of their activation, remains stable, reflecting the stable structure of the organization within the system. The result is a distinctive pattern of if…then…relations, or behavioral signatures, manifested as the individual moves across different situations (2004: 11, emphasis his).
