here—without any retraction of Gesture 2, and then produces Gesture
4 without retracting his hands. Gesture 4 happens to be a second
repetition of Gesture 2. This time, it is slightly longer than the first
repeat (0.92 s) and the gesture features are more similar to the original
production of the gesture as illustrated in Figure 5. In this second
repetition, the amplitude of the movement is slightly larger than in
the first repetition and finger tension is also greater. What is different
from the original gesture is the position of the hands: the palm of the
left hand is facing up instead of the hand being on its side.
