1.1 Brain and Behavior and HM Case Study

Localization

certain areas control certain psychological functions (compartmentalization)

Strict Localization

clear distinctions in brain areas

Weak Localization

1 area may control many functions and vice versa

Evidence for Strict Localization

Broca’s Aphasia - speech production

Wernicke’s Aphasia - comprehension

Evidence for Weak Localization

destroyed rat brains and made them run a maze. Didn’t matter what part, but amount of brain mattered.

Equipotentiality

part of brain can take over for another part

Relative Localization

some parts are strict (breathing)

some distributed (memory)

HM study base facts

Approach: Biological/Cognitive

Researchers: Scoville & Milner

HM Method/Design/Setting and Sampling Method/Sample

longitudinal case study, field

HM, convenience

HM Procedure

Psychometric (IQ) testing

Direct observation

Interviews

Cognitive testing: memory recall, learning

MRI x2

HM Results and Findings

Brain structures that were removed are important for short → long term memory

Localization of memory types

HM Strength and Limitation

Triangulation - Both method and researcher, help to validate results

Only 1 Person - Low population validity
