While space control and generating open spaces on the field have been used to evaluate strategies for team performance, the temporal nature of space available for the ball carrier has not been explored. This work proposes the temporal nature of space available for the ball carrier in the ...
Proposition 2 If X and Y are normed vector spaces and f is linear, then f:X→Y is open iff f(B) contains a ball centered at 0∈Y when B is a ball of radius 1 about 0∈X . Proof: A normed vector space is a metric space. Thus by Proposition 1, f is open iff for all any...

Subjects were informed that they would feel a tactile vibration and hear sounds approaching toward and/or receding from them (or they would see a virtual ball in Experiment 7). They were informed that sounds (or the visual stimuli, in Experiment 7) were task-irrelevant, and that their task...
