a type of sociometric test in which an individual in a therapy group is encouraged to improvise freely in reenactments of typical life situations with other members of the group who have been judged to be emotionally related, positively or negatively, to that individual. The goal is to gain insight into interpersonal relationships that are not revealed by the standard sociometric test, which deals only with attraction and rejection among members in a group.
