Old Brain Theories
This group of people believes that the brain is a "whole intelligence" where the parts of the brain work together to perform functions.
Whole Brainers
This part of the brain is in control of decision making, personality, and impulse control.
Prefrontal cortex
Developmental Mismatch theory
This person had a tamping iron enter through their skull, damaging the prefrontal cortex.
Phineas Gage
What is the name of the thing that caused Phineas' injury?
Tamping iron
This group of people believe the brain is made of smaller organs that each perform different functions.
Phrenologists or Localizers
This part of the brain is in control of generating the reward feeling and generating emotion.
A person might speak without thinking or drive in risky ways (any risky or impulsive behavior).
This group of people experiences a long stage of brain changes and development from 12-22ish
Adolescents
Did phrenologists have the technology to confirm their theory?
No
Why do Whole Brainers believe that Phineas supports their side?
Phineas is alive, so the whole brain must be able to perform the function of any part.
This lobe of the brain is in charge of helping us to process sound and memories.
Temporal lobe
What was one complication that Blakemore and her colleagues faces when trying to find evidence for Steinberg's theory?
They had to make sure the quality of the scans were good, especially for the limbic system.
This person proposed a theory that said the limbic system might mature before the prefrontal cortex, which causes adolescents to take more risks than other age groups.
Steinberg
What type of scans did Blakemore use to test Steinberg's theory?
MRIs
Why do phrenologists believe that Phineas supports their side?
-Phineas did not die because the iron did not hit parts of the brain needed for life
-Phineas is changed (personality)
This lobe of the brain helps us to process the things we see.
Occipital lobe.
Blakemore and her colleagues needed to find people who had MRI scans at three points in their lives. What were these 3 points?
late childhood, mid-adolescence, & late adolescence.
This person, along with colleagues, conducted a study to see if the developmental mismatch theory was correct.
Blakemore
Which brain theory group was correct about the structure/functioning of the brain?
Both groups were correct in some ways but wrong in others: the brain is both centralized and localized.
This part of the brain is in charge of automatic functions like breathing and heartbeat.
Brain stem.
Fill in the two blanks: Blakemore and her colleagues checked the volume of ____________ in _____ (number) regions of the brain.
gray matter; 3 regions
This doctor is the one who primarily worked with Phineas Gage and presented his case before groups of doctors, including the Whole Brainers & Phrenologists.
