Unit 10 - The IB Curriculum - A Conceptual Model

Ever wondered why you can draw a picture while jamming to your favorite song without confusing the lyrics with your art? You&#39;ve got Alan Baddeley and Graham Hitch to thank for cracking this mystery in 1974 with their Working Memory Model.

&nbsp;

Let&#39;s dive in and explore this fascinating concept!

Researchers used to think that Short Term Memory (STM) was like a small closet, holding around 7 items (give or take 2) of any type, be it sounds or images. But things got weird when they started using the dual-task technique.

&nbsp;

Imagine trying to memorize a list of words (that&#39;s sound for ya!) while also remembering a bunch of geometrical shapes (visuals, baby!). You&#39;d expect the two tasks to get tangled up, right? But surprise, surprise, they don&#39;t always!

&nbsp;

For instance, you can sketch a tree while memorizing a sequence of numbers spoken out loud. Your sketch doesn&#39;t get all number-y, and you don&#39;t start hearing tree shapes. Crazy, right?

To untangle this mystery, Baddeley and Hitch proposed the Working Memory Model. This model sees STM not as a single, boring old closet but rather as a lively, bustling control center.

&nbsp;

It has three core elements

<ul>
	<li>Central Executive: The Boss who manages and delegates tasks.</li>
	<li>Visuospatial Sketchpad: The &quot;inner eye&quot; that takes care of all the images and spatial info.</li>
	<li>Phonological Loop: The &quot;inner ear&quot; and &quot;inner voice&quot; combo, holding and manipulating sound info.</li>
</ul>

<ul>
	<li>Visuospatial Sketchpad (Inner Eye): When you&#39;re trying to remember a route to your favorite ice-cream store, or the shape of a funky new logo, that&#39;s the inner eye at work, handling your visual and spatial data.</li>
	<li>Phonological Loop: This one&#39;s like a little band duo:</li>
	<li>The Inner Ear listens passively, just holding the sounds you hear. If your friend tells you a joke, the inner ear holds onto the punchline.</li>
	<li>The Inner Voice is more active. Firstly, it can convert visuals to sounds. When you read this text silently, you&#39;re probably &quot;hearing&quot; it in your head. That&#39;s your inner voice turning visual (text) to auditory (sound). Secondly, it rehearses the info from the inner ear, repeating it to help remember it longer, like when you repeat a phone number over and over to memorize it.</li>
	<li>Central Executive: This one&#39;s the boss, juggling the visuospatial sketchpad and phonological loop. It ensures they&#39;re both working effectively and not stepping on each other&#39;s toes.</li>
</ul>

But in 2000, the model had an upgrade. Baddeley and Hitch added a fourth player: the Episodic Buffer. It&#39;s like a master chef that blends info from the other components and ties it with our long-term memory. So, it not only remembers the taste of the ingredients (information) but also knows how to cook up a delicious memory meal!

&nbsp;

And there you have it - the vibrant dance of memory! This concept should help you understand why you can remember song lyrics and drawings at the same time, without mixing them up. It&#39;s all thanks to your brain&#39;s brilliant backstage crew!
