1. Psychwrite #14:
Date: 1 pt Copy question: 1 pt Answer (in at least 3-5 lines): 3 pts Are you more of a creative, artistic person, or more logical and analytical person? How do you know? What does this mean in terms of being right or left brained?

2. Some people are left-brained, others are right-Brained
Myth #4

4. Exaggeration of a kernel of truth
Are some people “left-brained” and others “right-brained?”
1. Good evidence that two sides of brain differ in their functions.
Injury
Brain imaging techniques = differences in activity when doing cognitive tasks

5. Right hemisphere damage (ignores left)
The right hemisphere perceives the left half of space. When damaged, patients neglect the left half of space. In this example, patients were instructed to "draw the face of a clock, put all the numbers in, and make it say 10 after 11."

7. 2.

8. Demonstration
*Have a pen/pencil in BOTH hands

9. “Split-brain patients”: Researchers
Roger Sperry Michael Gazzaniga

10. 3. Corpus callosum

11. Research
Evidence for superiority of one or other hemisphere for performing certain tasks: “Split brain” patients 4. Epileptic seizures Sever nerve tracts connecting left/right hemispheres

12. 5. Longitudinal fissure (LONG)

13. 7. Scientific american frontiers

14. Corpus callosum… your information highway
2 hemispheres share information extensively
Two hemispheres are much more similar than different in their functions
“Pop-psychology’s” take… too simplistic

15. 8. Left field is processed by right
8. Left field is processed by right. Right field is processed by the left. 9.
The Optic Chiasm is the region for cross-over.
10. Visual Cortex – at the back.

16. What do you see?

17. What about the snowman scene?

18. 11: Multiple choice question
A word “key” is briefly flashed in the left visual field and the word “ring” is briefly flashed to the right visual field of a split-brain patient. The individual will be able to a. say “key” b. say “ring” c. pick out a key from a box using the right hand d. draw a picture of a key using the right hand
B. Say “ring”

20. Hemispheres in the brain (right handed)
12. Left
13. right
Language Logic
Spatial Facial recognition

21. Conclusions?
14. Left & right hemisphere are RELATIVELY better at different mental activities. Differ in HOW they process tasks rather WHAT they process.

22. Conclusions
15. Example: Language Left: Better at specifics of speech (grammar and word generation) Right: Better at intonation and emphasis of speech

23. 16. Spatial right?
Right : better at dealing with a general sense of space Left : becomes active when the person locates objects in specific places

24. 17 & 18. Language centers

25. The Brain #6
Language & Speech: Broca’s & Wernicke’s areas Paul Broca Tan’s brain

26. Hemispherectomy: cameron mott Brain plasticity

27. Research on creativity & the brain
Creativity does not involved a single brain region or single side of the brain. Depending on the stage of the creative process AND what you are trying to create, you use different brain regions. These brain regions WORK TOGETHER…a TEAM!

28. 19. Conclusions…you are whole-brained!
It is not that one hemisphere or the other can’t perform a given task; It’s just that one of them can perform it faster and better than the other!
