Transcript of Schema Theory
A method of increasing the parameters of Recognition Schema, making it more generalized and stronger. This can be done using variable practice schedules as well as variable practice methods.
What is Schema Theory?
According to Schema Theory, when people practice a particular class of movements, they acquire a set of rules (Schema), that they use to determine the parameter values necessary for performing different versions of the action. Developed by Richard Schmidt in 1975.
How does this demonstrate Schema Theory?
1. Pair up
2. Align tables so that one partner is on each end
3. Make a paper football
4. Listen to rules
5. Game On!
NBA Skills Challenge
Are these examples of Schema Theory?
Generalized Motor Program
This captures the basic form of our movements. It’s referred to as generalized because it doesn’t just produce one specific motion. It can produce a variety of motions such as height or power. The theory is basically that our exact motions produced by a GMP are driven by ‘parameters” (required speed, height)
Recall schema is what provides the parameter values for the GMP after observing your situation and intentions. For example, if your badminton opponent has just cleared the shuttle to the back left corner of your court then a Recall Schema will feed parameters of direction and speed to a GMP for doing a split step followed by a sequence of foot movements designed to get you in position to hit the shuttle.
The Recognition Schema is what allows us to know when we've made an error, just by feel. It is an expected feeling for the movement.
Information received from the various receptors prior to the reponse, such as proprioceptive
information about the positions of the limbs and body in space, as well as visual and auditory information about the state of the environment.
Specifications of variations of the basic pattern possible by changing important elements like the speed and the forces involved.
The success of the response in relation to the outcome originally intended.
Recall Schema is used in Ballistic Movements. It consists of 3 stages.
Occurs in movements that have the potential necessity to adapt during the movements execution. Also consists of three stages.
Same as Recall Schema. Less for you to write. You're welcome.
Response produced sensory information. Actual feedback stimuli received from the eyes, ears, proprioceptors.
Also the same as Recall Schema. You're welcome again.
Let's Learn a New Activity
Split into two groups
One in the classroom
One in the gym
What did you notice?
Which group had more points?
Was it easier for one group?
Classroom group will develop a new GMP, and practice the movements before actually performing the activity.
