Document Summary
6 groups of competitive hockey players; 4 conditions: Skating and identifying geometric figures (skating and cognitive task) Wanted to find out what age skating became an automated task. As complexity of task increased, skating time increased (took longer) for younger players aged 6- As age increased (11-19), there was no difference in time across the 4 tasks. Shows that from 6-10 years old, skating is not an automated task (attentionally demanding, exceeds attentional pool); for older age groups skating is not attentionally demanding. Younger age groups now practice without pucks to increase skating ability. Coordination: finger wiggling task cannot be done unless you have split brain (no corpus collosum) Moving in an anti-phase fashion; attentionally demanding. As frequency increases to about 5hz, your movement destabilizes, causing you to fall into an in- phase pattern. Because cns likes to have one temporal pattern for each digit.
