CHAPTER 3.13: Hemispheric Specialization

Question 1

what is the corpus callosum.

Answer 1

a densely concentrated bundle of nerves connecting the 2 hemispheres of the brain

Question 2

language function are specialized in the ____ part of our brain due to the location of _____ area and ____ bein located in that hemisphere.

Answer 2

left, brocas, wernickes

Question 3

Answer 3

NO

Question 4

hemisphere specialization can also be called what?

Answer 4

cerebral laterization

Question 5

why would it be evolutionarily beneficial for the brain to participate in cerebral laterization?

Answer 5

increasing processing efficiency (parallel processing)

Question 6

what is lateralization of function?

Answer 6

cases in which one hemisphere is dominant for/specializes in processing of certain types of info

Question 7

how can hemispheric differences be studied?

Answer 7

split brain patients - where their corpus collosum is severed in epileptic patients

Question 8

anything in the left visual field is communicated to the ____ hemisphere and vice versa.

Answer 8

right

Question 9

what is a global detail?

Answer 9

the overall stimuli given (ex. given tan L made up of tiny ns, the global detail is the big L)

Question 10

what is a local detail?

Answer 10

the little tiny parts of the stimuli (ex. given tan L made up of tiny ns, the local detail is the small ns)

Question 11

would a person with left hemisphere damage report seeing just global or local details? why?

Answer 11

global, as a properly working left hemisphere is supposed to process the local details of situations

Question 12

would a person with right hemisphere damage report seeing just global or local details? why?

Answer 12

local, as a healthy right hemisphere processes the global details
