This paper explores the potential that the natural sciences of complexity may have to offer analogies and insights with regard to communicative processes in a group and the concept of the group matrix. The paper briefly reviews Foulkes' last formulation of the concept of the group matrix. It then draws on Mead's thought on mind, self and society, and on some analogies from the complexity sciences, to suggest a formulation of the emergence of mind in communicative interaction in a group.In his last paper on the group matrix, Foulkes (1973) says of a group-analytic group:What an enormous complexity of processes and actions and interactions play between even two or three of these people, or these people and myself, or between two in relation to another three, and so on. What enormous complexity, quite impossible to perceive and disentangle even theoretically all at the same time. How is it that they can nevertheless understand each other, that they can to some extent refer to a shared common sense of what is going on? (1973, p227) His answer to this question is 'the existence of a suprapersonal matrix ' (1973, p227). He sees this as an alterative to the view that what is happening in a group is due to the interaction of individual minds. He makes it clear (1973, p226) that he is talking about a psychic system, one of interacting mental processes, not individuals interacting to form a superimposed social system.
Communication and the group matrix as suprapersonal psychic systemAccording to Foulkes, when people come together in a group they create a new phenomenon, a suprapersonal psychic system, which Foulkes describes in a number of different ways as: the context of the group, that is, the background in which the individual is figural (1973, p230); a total unified field of mental happenings of which the individual is a part (1971, p214); transpersonal processes that go right through individuals like X Rays, but which those individuals can modify, elaborate and contribute to in their own way (1973, p229); interacting mental processes that transgress the individual (1973, p229). By mental processes, he seems to mean communications such as 'acts, active messages, movements, expressions, silent transmissions of moods …' (1973, p213) both conscious and unconscious. In the latter category he includes resonance, transference, projection, and so on.Although earlier he had talked about the matrix as a group mind, in his last paper on the matrix he rejected that terminology and talked about 'the mind' as interacting transpersonal mental process, or 'mind' as a multiperson phenomenon (1971, p225). As I understand it, he is saying that an individual mind is the transpersonal processes that penetrate him or her through and through to the core so that individual mind is a multiperson phenomenon. This dynamic formulation begins to suggest a view of causality in which interaction is perpetually constructing the future when in their coming together people create the new phenomena of
