Brain to Brain approaches to joint actions

Joint actions require an ability to understand and predict the actions of others far enough into the future to have time to plan and execute matching motor programs. Here I will review experiments in which we have tracked information flow from one brain to another to show that the motor system seems to play a key role in these functions. I will embed this experimental data in a Hebbian learning model, which posits that predictions are the result of synaptic plasticity during self­observation. Jointly this talk will aim to trigger thoughts on how we can ...

Improvising Interaction

Even the most tightly scripted solo performances involve improvisation; the detailed execution of each note or word cannot be completely determined in advance. In joint performances the challenge of co­ordinating the actions of multiple people in real­time becomes even more complex. One response to this challenge has involved appeal to prediction using ‘forward models’ from computational models of action planning. These models involve automatic activation of motor representations of the future perceptual consequences of an unfolding action. Although normally associated with action production, if a person perceiving the action can also produce a forward ...

“Quantifying JI” Short talk 1.2: Tommi Himberg - Mirroring improvised hand movements in a dyad

We studied coordination and movement kinematics in a mirror game. 32 participants (18 f, 14 m; mean age 25.2 years, range 19–37) performed circle­drawing and freely improvised hand movement mirroring tasks in dyads. The participants were standing face­to­face, right index fingers pointed at each other, fingertips 10–15 cm apart. In turn, one of the participants was appointed the leader, or the dyad was instructed to share leadership. Hand movements were recorded using an optical motion capture system. Joint leadership resulted in smoother performances than the leader–follower condition; the follower participant would often hesitate or ...

Joint Improvisation in Music and Dance: Some Preliminary Phenomenological Considerations on Improvisation as an Enactive Process

"I have been a practitioner of soloandjointimprovisationin music and dance for a while. And I have alwayswondered what the main differences were between the two. What I am particularly interested in are the typeof experiences that allow me to cognitively function in a different way, that is, that allow me to explore new(cognitive) territories. In particular, there is always a moment, in an improvisation, be it solo or joint, when Iam in the « zone », that is, in a type of trance where my conscious mind is not in control anymore, or at leastseems not to be in control ...

Going into the unknown in science and art

Scientists must grope into the undefined place beyond the known. So must improvisation theater actorswalking onto the stage with no idea what will happen next. Improvisation theater developed practices thathelp groups of actors create a new scene on the spot, by focusing on mutual support: saying yes to eachothers ideas and bypassing the inner critic that spoils our spontaneity. I’ll describe how as a scientist by dayand improvisation actor by night, I learned from theater how to do better science. The concepts are universaland can apply to unexpected situations across disciplines.
