It is Professor Heise's premise that the psychology of affect
theoretically governs common social actions, such as those of a patient
toward a doctor or a mother toward a child. Human behaviour, he argues,
normally promotes the maintenance of a steady emotional state. Should
events produce undue strain, the individual attempts to anticipate
subsequent developments, formulate a course of action and create new
events designed to confirm his established sentiments. This book lays
the foundation for this approach to interpreting events: it offers a
mathematical model grounded in empirical procedures for analysing what
happens in social relationships. Topics covered in the book include how
situations are defined and events constructed, past research on
processes of impression formation, the mathematical derivation for
predicting behaviour and the application of this approach to the study
of roles. Throughout the book, the theory is shown to be relevant not
only for the construction of social action, but also for the
reconstruction of events and, in particular, for the identification of
social deviants.
