Earlier experimental studies by one of us (Kelso, 1981a, 1984) have shown that abrupt
phase transitions occur in human hand movements under the influence of scalar changes in …

The question of agency and directedness in living systems has puzzled philosophers and
scientists for centuries. What principles and mechanisms underlie the emergence of agency? …

Movement time varies as a function of amplitude and requirements for precision, according
to Fitts' law, but when subjects perform two-handed movements to targets of widely disparate …

In the search for principles of pattern generation in complex biological systems, an
operational approach is presented that embraces both theory and experiment. The central …

Spontaneous social coordination has been extensively described in natural settings but so
far no controlled methodological approaches have been employed that systematically …

In this chapter we aim to identify collective variables (or order parameters) and their dynamics
(stability, loss of stability, hysteresis . . .) for perceptionaction patterns. To do so we extend …

The present article represents an initial attempt to offer a principled solution to a fundamental
problem of movement identified by Bernstein (1967), namely, how the degrees of freedom …

Multistable coordination dynamics exists at many levels, from multifunctional neural circuits
in vertebrates and invertebrates to large-scale neural circuitry in humans. Moreover, …

… even to its molecules such as neurotransmitters, Scott Kelso's book promotes quite a different
… of experiments, ingeniously devised and performed by Scott Kelso, and the application of …

Why do we divide our world into contraries? Why do we perceive and interpret so many of
life's contraries as mutually exclusive, either/or dichotomies such as individual~ collective, self…
