28. Imagine the image shown on the left represents
the data from Kelso's finger wiggling experiment
shown in the slides and the text. Could the current
order parameter be in-phase finger wiggling?
a. Yes
74%
b. No
c. cannot be reasonably inferred from the
diagram
31. How is the run-walk data similar to Kelso’s
finger wiggling data?
a.
The pattern of change in movement from walk to run is
similar to the change from in-phase to anti-phase
coordination
b. The pattern of change in movement from walk to run is
similar to the change from anti-phase to in-phase
coordination

As you increase the value of the (41. control parameter), the
(42. order parameter) will remain the same in terms of its
coordination pattern, but its (43. stability) will often change. If
the (44. stability) does change, then further manipulations of
the (45. control parameter) may result in (46. critical
fluctuation), at which point a transition to a new (47. order
parameter) is imminent. It is worth noting that this transition
often occurs at a different value of the (48. control parameter)
when the (49. control parameter) is increasing than when it is
decreasing, which is because the coordination pattern you are
currently in seems to exert a sort of control over your
movements (something Haken referred to as the slaving
principle). We refer to this last phenomenon as (50. hysteresis)
