From Individual Traits To Couple Behavior

Micro-macro links between individual psychophysical traits and couple behavior are established. The analysis is carried out through a simple idealized model that mimics couples not influenced by their social environment. The functions describing the traits, i.e. the reactions to the love and appeal of the partner, are quite general. In particular, they allow one to take into account relatively sophisticated characteristics like insecurity and bias. The results are interesting even if some of them have already been discovered in extremely special cases. Some features of the idealized model are also used to theoretically support important behaviors identified empirically by psychotherapists.
