Cognition materializes in an interpersonal space. The emergence of complex behaviors requires the coordination of actions among individuals according to a shared set of rules. Despite the central role of other individuals in shaping one’s mind, most cognitive studies focus on processes that occur within a single individual. We call for a shift from a single-brain to a multi-brain frame of reference. We argue that in many cases the neural processes in one brain are coupled to the neural processes in another brain via the transmission of a signal through the environment. Brain-to-brain coupling constrains and shapes the actions of each individual in a social network, leading to complex joint behaviors that could not have emerged in isolation. (Source)
Very much agree with this statement, which is the intro to a short scholarly opinion piece on interpersonal cognition.
The very basis of FIML practice is the interaction of two people. The FIML technique is designed to allow two people to become deeply aware of the (normally) elusive, idiosyncratic, and highly complex signalling mechanisms that are always functioning whenever they interact.
As partners become richly aware of this dynamic system, they will find they are able to change it for the better by removing mistakes and ambiguity. Mistakes and ambiguity are prominent—indeed, characterize—virtually all normal interpersonal communication. By largely removing these factors from their interpersonal communication, partners will experience significant improvements in communication, general awareness, and feelings of well-being.
The linked essay asks the following question: How to further develop principled methods to explore information transfer across two (or more) brains?
One answer is do FIML practice. Rather than study themselves from outside, FIML partners will study themselves as they are in all of their own unique complexity as uniquely “coupled brains.” In the terms of the linked paper, FIML practice is “brain-to-brain coupling” that leads to “complex joint behaviors” that cannot possibly “emerge in isolation.”
FIML practice provides a general “shared set of rules” that allows “complex behaviors” to “emerge” between two (or more) people. These “complex behaviors”, in turn, give partners the opportunity to control and transform how they “shape” their minds.
