Describe the experiment in which people held a pencil between their teeth and lips.

it is the primary taste cortex and it also is an area that is responsible for disgust


What are the roles of the right and left hemispheres in the detection and expression of emotion?

Should you pay attention to your gut feelings? What evidence suggest that they are useful guides to behavior?

Yes; students were shown slides of either snakes or spiders, but were unrecognizable and then were given a shock after either the snake or spider slide. Most of those shocked after spider pictures developed a bigger heart rate increase after spider pictures and people shocked after snake pictures learned and increased heart rate after snale pictures, even though neither group could consciously identify the pictures. And those who were accurate at reporting their heart rate increase, were good at predicting whether they were about to get a shock.


Describe the behavior of people with damage to the prefrontal cortex.

They are often emotionless except for some outbursts of anger and impulsive in their decision making.
