Welcome to the World of Motor Learning!
Ever wondered how a goalkeeper knows exactly where to dive to save a penalty, or how a basketball player makes a perfect free throw while the crowd is screaming? It all comes down to how our brain handles information. In this chapter, we are going to explore the Information Processing Model. Think of your brain as a super-fast computer that takes in data, decides what to do, and then tells your muscles to move. Understanding this process is the secret to moving from a beginner to a pro!
What is the Information Processing Model?
The Information Processing Model explains the steps our brain goes through when we perform a physical skill. It’s like a four-step loop that happens in a split second. Don't worry if it sounds technical—just think of it like ordering food at a drive-thru!
The Four Main Stages:
1. Input: You see, hear, or feel what is happening around you.
2. Decision Making: Your brain processes the info and picks the best move.
3. Output: Your body performs the action.
4. Feedback: You see the result and learn for next time.
Analogy: Imagine you are playing "Rock, Paper, Scissors." Your eyes see your friend's hand (Input), your brain decides to play "Paper" (Decision Making), your hand moves (Output), and you see that you won (Feedback)!
1. Input (The "Sensory" Stage)
This is where you gather information from your environment through your senses. In sports, the most important ones are:
• Vision (e.g., seeing where the ball is).
• Hearing (e.g., hearing a teammate shout "Pass!").
• Proprioception (e.g., the "feel" of your body's position in space).
Selective Attention: This is a very important part of the Input stage. It is the ability to filter out distractions (like the crowd cheering) and focus only on the relevant cues (like the movement of the opponent’s feet).
2. Decision Making
Once the brain has the info, it searches your Long-Term Memory to find a "plan" (also called a Motor Program) that fits the situation. If you’ve practiced a skill many times, this happens almost instantly!
3. Output
The brain sends a message through the nervous system to the muscles. This results in the actual movement or skill being performed.
4. Feedback
This is the information you receive during or after the movement. It tells you if you were successful. Did the ball go in the hoop? Did that jump feel balanced? This feedback goes back into the loop as "Input" for your next try.
Quick Review Box:
Input = Gathering data.
Decision Making = Planning the move.
Output = Doing the move.
Feedback = Checking the result.
Key Takeaway: Information processing is a continuous loop. Every time you receive feedback, your "computer" updates its data to make the next decision better!
Novice vs. Expert: What’s the Difference?
Have you ever noticed how a professional athlete looks like they have "all the time in the world," while a beginner looks rushed and panicked? This is because their Information Processing works differently. Let’s compare a Novice (beginner) and an Expert (pro) using the model stages.
At the INPUT Stage
• Novice: They often get overloaded with too much information. They find it hard to use Selective Attention, so they might get distracted by the noise of the crowd or the wrong cues.
• Expert: They are masters of Selective Attention. They know exactly what to look for. They can "read" the game and predict what will happen before it even starts!
At the DECISION MAKING Stage
• Novice: They have fewer Motor Programs stored in their memory. Their brain has to "think hard" about every single step, which makes their reactions slower.
• Expert: They have thousands of Motor Programs stored from years of practice. Their decisions are automatic and much faster.
At the OUTPUT Stage
• Novice: Movements often look jerky, uncoordinated, or inconsistent. They use too much energy for simple tasks.
• Expert: Movements are smooth, efficient, and consistent. They make difficult skills look easy!
At the FEEDBACK Stage
• Novice: They rely mostly on External Feedback (what the coach says or seeing the score). They often don't know "why" they made a mistake.
• Expert: They use Internal Feedback (the "feel" of the movement). They can often tell they made a mistake the moment the ball leaves their hand, even before they see the result.
Did you know? Experts use "Anticipation." Because they process information so efficiently, they can predict where a ball will land just by looking at the opponent's body position before the ball is even hit!
Common Mistake to Avoid: Don't think that experts just "move faster" because of their muscles. Often, they are faster because their Information Processing is more efficient—their brain gets a "head start" on the movement!
Key Takeaway: Experts are better because they filter out junk info (Input), have faster automatic plans (Decision), move more smoothly (Output), and can feel their own mistakes (Feedback).
How to Remember This for the Exam
Use the mnemonic "I Do Our Fun" to remember the stages of the Information Processing Model:
• I - Input
• D - Decision Making
• O - Output
• F - Feedback
Final Tip for Success: When answering exam questions about a specific sport, always try to use examples. If the question asks about Input, talk about a netball player seeing a teammate move into space. If it asks about Feedback, talk about a swimmer feeling the water resistance on their arms. This shows the examiner you really understand how the theory works in real life!
