Document Summary

Mini review/potential exam questions from lecture 8: you are being attacked by a tiger (or relaxed on a beach in hawaii). Participants shown a gory/horror/explicit car crash scene and had to rate it on a scale from 1 10 with 10 being very disgusted/nauseous and would not watch again. When film is shown on left side, which is processed by the right hemisphere, most rated 9. When film is shown for those with split brain hemisphere, most rated 6. When shown to both hemispheres, most rated 6; here, we see that the left hemisphere is dominant between the two. Note: left hemisphere perceives things as less negative compared to the right hemisphere: general processing, brain scans (fmri) Interested in frontal lobes which is associated with humor: behind the left eyeball is the prefrontal cortex, one part of the frontal lobe. When we understand a pun, prefrontal cortex shows activity.
