Document Summary
Kinesiology: psycho-motor behaviour extrafusal muscle fibre: power producing muscle fibres causes contractions run in parallel direction intrafusal muscle fibres, proprioceptor sense. Motor learning designed to detect stretch in a muscle tells the brain the orientation, position and movement of our body internal processes of practice or experience that leads to a relatively permanent change in performance capability. Motor control study of movement neural, physical, behavioural and cognitive aspects of movement historical development of motor control/ learning these 4 contributed to motor learning/control: psychology. Shiffirn proposed the short term memory system which has capabilities to turn into long term memory. Examined how short term memory contributes to learning proposed that: the brain acts like a computer serial nature of information processing b) memory is different for different tasks (motor tasks vs. cognitive tasks, engineering. Soldiers given very simple tests (unrelated to piloting) to determine if they would be successful pilots.
