Document Summary
How movements/actions interact with themselves or other movements. Interacts without you wanting it too: single hand vs dual hand vs same vs diferent patterns. 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 helps each other complete their tasks: temporal (time) construct. You need to trade-of speed and accuracy it is hard to be good at both at the same time. October 5, 2015: moving to a single point, efective target width is larger when moving at a greater rate, moving farther or faster= accuracy sufers. Paul fitts" task: tap between 2 targets as rapidly as possible for 20 seconds, maintaining. Movement time (mt) (e. g. average duration per tap) Movement distance (d) (e. g. distance from target centre to centre)
