In this chapter I describe what I call "Gestalt group process," which integrates the principles and practices of Gestalt therapy and group dynamics. It is a model in which the leader wears bifocal lenses, paying attention to the development of the individuals in the group and to the development of the group as a social system. From this perspective, the group is regarded not just as a collection of individuals, but as a potent psychosocial environment which profoundly affects the feelings, attitudes and behaviours of the individuals in that system, and conversely, is profoundly affected by the feelings, attitudes and behaviours of the individual in that system. The chapter is divided into two sections: The first part deals with some personal and historical antecedents, and the second part with the theory and practice of this bifocal approach to personal development in groups.
