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?

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

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."

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

3. Corpus callosum

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

5. Longitudinal fissure (LONG)

7. Scientific american frontiers http://www.youtube.com/watch?v=lfGwsAdS9Dc

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

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.

What do you see?

What about the snowman scene?

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”

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

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

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

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

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!

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!
