Symmetrization, Mirroring and External Reality: An 'Inner' Perspective

In the last two decades, mirroring systems have been detected in the monkey and in the human brain. The mirroring mechanisms have been considered as the neural basis for social cognition and interpersonal reactivity, and they have been assumed to support imitation, sharing of emotional states and empathy. Here I would like to compare 'mirroring phenomena' to 'symmetrization phenomena'. In psychoanalytic literature, the construct of symmetrization has been proposed in the context of the Bi-Logic theory by Matte Blanco in 1975, on the basis of clinical evidence obtained in the psychoanalytical setting and following a theoretical analysis derived from the Freudian distinction between Primary and Secondary Processes. I will consider two different types of behaviours, empathic social interactions and the creation of transitional objects and spaces as defined by Winnicott in order to argue that symmetrization, in Matte Blanco's terms, cannot be reduced to mirroring. I will then sketch a hypothesis on the interplay between the symmetric aspects of the mind and external reality in the development of higher relational functions of humans, also taking playing, arts and creativity into account. Finally I will describe the paradigmatic shift in neuro-imaging studies that was introduced with the discovery of the 'Default Mode Network' and its potential relevance in the research on the symmetric and asymmetric aspects of the human mind.
