The Origins of Neuropsychology

• Psychology - Experimental
• Neurology Clinical
• Emergent Clinical Fields
• Behavioral Neurology
• Neuropsychology
• Emergent Experimental Fields
• Cognitive Neuroscience
• Experimental Neuropsychology

Research Populations

• Human patients with brain damage or disorders
• Neurologically intact humans
• Nonhuman animals
• primates
• rodents
• invertebrates

3
Patients with Brain Damage

• The lesion approach
• Examples 1. HM
• remember him???
• 2. Blindsight
• huh?
• Any problems with this approach???????

WHAT'S NEW WITH THE AMNESIC PATIENT H.M.?
Suzanne Corkin     H.M. became amnesic in 1953.
Since that time, nearly 100 investigators, first
at the Montreal Neurological Institute and since
1966 at the Massachusetts Institute of
Technology, have participated in studying him. We
all understand the rare opportunity we have had
to work with him, and we are grateful for his
dedication to research. He has taught us a great
deal about the cognitive and neural organization
of memory. We are in his debt.

Problems with the Lesion Approach

• Variability in regions of damage
• Example language mapping

7
BTW DISCLAIMER

• The broken brain may not process information in
  the same way as the intact brain..
• EG Stiles developmental studies of spatial
  processing

8
Behavioral Methods

• Clinical Interviews
• Information from caretakers
• Neuropsychological Testing
• Battery Approach
• Decision Tree Approach
• Experimental Testing
