What is Psycho-Motor Learning? (Lecture #2)
Gross signal/movement -> whole body
Fine signal/movement -> specific body part
Messages sent from brain to extrasfusal muscle fibers
- Extra allow for contraction
Intrafusal muscle fibers sense stretch
- Intra very in tune with the environment
- Ex: leaning over a cliff you tighten up and lean less than you would over the ground
Motor learning -> a set of internal processes associated with practice or experience leading to a
relatively permanent gain in performance capability
- meaning you can retain the skill learned and use the skill again (riding a bike)
Motor control -> an area of study dealing with the understanding of the neural, physical and
behavioral aspects of movement
- Ex: studying the deficits associated with damage to certain parts of the brain (neural)
- Ex: studying reaction time and certain action- the actual actions (behavior)
3. None
1. Three processes -> perception (identify), cognition (think about what we perceived) and action
(act on what we perceived)
- In this order leads to motor movement
2. Depending on the information that needs to be remembered, info will be stored at different
locations in the brain (behavior and cognitive info stored differently)
Melton -> better scores on the test means better fighter pilot
- Basic tests that are not done at the same time -> unlike when flying a plane and
everything happens at the same time
