Document Summary
How movement and actions interact with themselves or other movements. Coordination: how movements and actions interact with themselves and other movements. Pat head and rub belly at the same time. Requires an individual to perform two tasks simultaneously, in order to compare performance with single-task condition. A competition for attentional resources, or competition for information processing mechanisms (the limitation of capacity of attentional resources is exceeded) Bimanual aiming/structural interference: limbs help each other complete their tasks. You"ll see that that one will be a lot better. Speed-accuracy tradeoff: faster you move, less accurate you are you need to trade-off speed and accuracy it is hard to be good at both at the same time. Tap between 2 targets as rapidly as possible for 20 seconds, maintaining 95% accuracy. Examine relation between: movement time (mt) (e. g. average duration per tap, movement distance (d) (e. g. distance from target center to center, target width (w)
