Unit 10 - The IB Curriculum - A Conceptual Model

These studies explore the concept of &quot;lateralization,&quot; which is how different functions are divided between the two hemispheres of our brain.

<ul>
	<li>Lateralization is about how the left and right parts of our brain handle different tasks.</li>
	<li>Think of it as each side having its own special talent!</li>
	<li>Lateralization is a special case of &quot;localization,&quot; meaning specific brain parts handle specific tasks.</li>
</ul>

<ul>
	<li>Roger Sperry - The main dude behind this research.</li>
	<li>Michael Gazzaniga - Joined Sperry and published the human study results in 1967.</li>
</ul>

First experiments were on animals like cats. Imagine a cat with a split brain &ndash; wild, right?

Some humans had the connection between their brain halves (the corpus callosum) cut to treat severe epilepsy. It sounds scary, but guess what? One guy even joked he had a &quot;splitting headache&quot; after his surgery!

<ul>
	<li>Participants stared at a dot.</li>
	<li>Images were shown super quickly to the left or right side of their vision.</li>
	<li>Cool Fact: The left side of our vision is connected to the right side of our brain and vice versa!</li>
</ul>

<ul>
	<li>
	The Mysterious Spoon Incident

	<ul>
		<li>Shown a spoon on the left (so right brain sees it).</li>
		<li>They couldn&#39;t say &quot;spoon,&quot; but could pick one up.</li>
		<li>Why? The speech center is in the left brain!</li>
		<li>🌍 Real-world example: It&#39;s like seeing a friend in a crowd but not remembering their name.</li>
	</ul>
	</li>
	<li>
	The Talking Right Hemisphere

	<ul>
		<li>A word like &quot;pencil&quot; shown to the right hemisphere.</li>
		<li>They could pick a pencil but couldn&#39;t say it.</li>
		<li>🌍 Real-world example: It&#39;s like knowing a song&#39;s melody but not its lyrics.</li>
	</ul>
	</li>
	<li>
	The &quot;He-Art&quot; Puzzle

	<ul>
		<li>Word &quot;heart&quot; split so left brain sees &quot;art&quot; and right brain sees &quot;he&quot;.</li>
		<li>Result? They said &quot;art&quot; but pointed to &quot;he.&quot;</li>
		<li>🌍 Real-world example: It&#39;s like trying to sing a duet and messing up the harmony.</li>
	</ul>
	</li>
	<li>
	Simple Word Spelling

	<ul>
		<li>Some could spell words with their left hand (right brain). But then, couldn&#39;t say the word out loud!</li>
		<li>🌍 Real-world example: It&#39;s like typing a message and forgetting what you typed immediately after.</li>
	</ul>
	</li>
	<li>
	Artistic Right Brain

	<ul>
		<li>The right brain (left hand) was better at drawing pictures.</li>
		<li>🌍 Real-world example: Ever tried drawing with your non-dominant hand? Maybe you should!</li>
	</ul>
	</li>
	<li>
	Emotions Are Universal

	<ul>
		<li>Both brain halves can feel emotions. Show a funny or surprising picture, and both sides react!</li>
		<li>🌍 Real-world example: Laughing at a joke whether you hear it in your left or right ear.</li>
	</ul>
	</li>
</ul>

<ul>
	<li>Left brain is the main chatterbox but the right can sometimes &quot;talk&quot; too.</li>
	<li>The right brain is the artsy one, better at visual tasks.</li>
	<li>Emotions? Both sides of the brain get them.</li>
</ul>

If you ever think you&#39;re bad at drawing, try switching hands! Your right brain might surprise you!
