Summary• EEG coordination dynamics:
– Develop “real” time analysis of brain~behavior
– Employ robust entrained responses
• Social Coordination dynamics:– Phi complex: for coordinated~uncoordinated
behaviors– Transitions/loss of stability: changes in
dynamics– Gating the influence of self and other on
ongoing behavior
