Welcome to Memory Models!

In this chapter, we are going to explore how your brain works like a high-powered computer when you play sport. Have you ever wondered how a goalkeeper knows exactly which way to dive, or how a tennis player reacts to a 100mph serve? It all comes down to Information Processing.

Don't worry if this seems a bit "sciencey" at first. We’ll break it down into small steps, using examples from the sports you love. By the end, you'll understand how we take in information from the game, make decisions, and turn those decisions into winning movements!

1. The General Information Processing Model

Think of your brain as a computer. Information comes in, gets "crunched," an action happens, and then you check to see if it worked. This happens in four main stages:

1. Input: Taking in information from the environment (e.g., seeing the ball move).
2. Decision Making: Choosing what to do based on that information.
3. Output: The actual physical movement (e.g., swinging the racket).
4. Feedback: Finding out if the move was successful (e.g., seeing the ball land in court).

A Closer Look at "Input"

We collect information through our senses. In PE, we focus on:

  • Exteroceptors: Senses from outside the body (Vision and Hearing).
  • Proprioceptors: Senses from inside the body. This is your "inner sense" of where your limbs are without looking at them (using your muscles, tendons, and joints).

The DCR Process

When you get an input, your brain goes through Detection, Comparison, and Recognition (DCR):

  1. Detection: Noticing the stimulus (e.g., "I see a ball.")
  2. Comparison: Comparing it to memories of past experiences (e.g., "This looks like a cross coming into the box.")
  3. Recognition: Realising what is happening (e.g., "I need to jump to head this ball!")

Selective Attention

Imagine you are playing football. There are fans screaming, teammates shouting, and the wind is blowing. Selective Attention is your brain’s ability to filter out the "noise" (the fans) and focus only on the "cues" (the ball and the defender). This prevents information overload.

Quick Review: Input is collected by senses, processed via the DCR cycle, and kept clear by Selective Attention.

2. Baddeley and Hitch: Working Memory Model

This model explains how we handle information while we are actually performing. It has several "compartments":

  • The Central Executive: The "Boss." It controls the whole system and decides which information to focus on.
  • Phonological Loop: Deals with sounds (e.g., hearing your coach shout instructions).
  • Visuospatial Sketchpad: Deals with what you see (e.g., the position of players on the court).
  • Episodic Buffer: Coordinates information from the other parts and sends it to your Long-Term Memory (LTM).

Short-Term Memory (STM) vs. Long-Term Memory (LTM)

Short-Term Memory is like a tiny sticky note. It can only hold about 5-9 pieces of information for about 30 seconds. If you don't practice or use the info, it disappears.

Long-Term Memory is like a massive library. It has unlimited storage and holds onto skills you’ve learned for years (like how to ride a bike or shoot a netball). When we play, we pull info out of the LTM and put it into the "Working Memory" to use it.

Did you know? Elite athletes have "chunked" their memories. Instead of seeing 11 individual players, a pro footballer sees one "pattern of play," which takes up less space in their Short-Term Memory!

3. Whiting’s Information Processing Model

Whiting’s model is just a more detailed way of looking at how we process info. Here are the key terms you need to know:

  • The Display: Everything happening around you (the physical environment).
  • Sensory Organs: Your eyes, ears, and touch.
  • Perceptual Mechanism: How we interpret the information (using the DCR process).
  • Translatory Mechanism: The "decision maker." It picks the right response for the situation.
  • Effector Mechanism: Sends the message to the muscles to move.

Common Mistake: Students often confuse the Perceptual and Translatory mechanisms. Just remember: Perceptual is about understanding what's happening; Translatory is about choosing what to do about it.

4. Response Time and Hick's Law

In sport, speed is everything. We use a simple formula to understand how fast you move:

\( \text{Response Time} = \text{Reaction Time} + \text{Movement Time} \)

  • Reaction Time: The time from the stimulus (the starting gun) to the start of the movement.
  • Movement Time: The time it takes to actually complete the physical action.
  • Response Time: The total time from the very start to the very end.

Hick’s Law

Hick’s Law states that the more choices you have, the slower your reaction time will be.
Example: If a goalie knows a penalty taker always shoots left, their reaction is fast. If the taker could shoot left, right, or center, the goalie’s reaction time increases (gets slower).

The "Bottleneck" (Single Channel Hypothesis)

Your brain can only process one piece of information at a time. This is the Single Channel Hypothesis. If a second stimulus arrives while you are still processing the first, you experience a delay called the Psychological Refractory Period (PRP).

Analogy: Imagine a narrow bottle. If you try to pour two drinks in at once, they get stuck. You have to finish the first before the second can go through. This is why a "fake" or "dummy" move in rugby works—it forces the defender to process the fake move first, making them too slow to react to the real move!

Takeaway: To improve response time, you can use Anticipation (predicting what will happen). Spatial anticipation is guessing where it will happen; Temporal anticipation is guessing when.

5. Schmidt’s Schema Theory

A Schema is a set of rules that helps us make decisions. Instead of having a separate memory for every single type of pass, we have a general "rule" for passing. Schmidt says there are two parts:

1. Recall Schema (Before the movement)

  • Initial Conditions: Where am I? (e.g., "I am on the 3-point line.")
  • Response Specifications: What do I need to do? (e.g., "How much power do I need for this shot?")

2. Recognition Schema (During/After the movement)

  • Sensory Consequences: How did it feel? (e.g., "The ball felt good leaving my fingers.")
  • Response Outcomes: What happened? (e.g., "The ball went in the hoop.")

6. Strategies to Improve Information Processing

If you are coaching a beginner who is struggling to process everything, try these tricks:

  • Selective Attention: Tell them exactly what to look for (e.g., "Watch the stitches on the ball.")
  • Chunking: Group information together so it’s easier to remember.
  • Chaining: Break a complex skill (like a gymnastics routine) into small links and join them together.
  • Mental Practice: Visualising the skill helps "burn" the pattern into the Long-Term Memory.
  • Improve Fitness: Being fitter means you stay alert and can process information faster for longer!

Final Encouragement: Memory models can feel like a lot of definitions, but they are all just different ways of explaining the journey from seeing the ball to scoring the goal. Keep practicing these terms and you'll have them "stored in your LTM" in no time!
