Developments in personality-social psychology, in social cognition, and in cognitive neuroscience have led to an emerging conception of personality dynamics and dispositions that builds on diverse contributions from the past three decades. Recent findings demonstrating a previously neglected but basic type of personality stability allow a reconceptualization of classic issues in personality and social psychology. It reconstrues the nature and role of situations and links contextually sensitive processing dynamics to stable dispositions. It thus facilitates the reconciliation within a unitary framework of dispositional (trait) and processing (social cognitive-affective-dynamic) approaches that have long been separated. Given their history, however, the realization of this promise remains to be seen.
