- Subjects will project aspects of their own personality into their responses
Describe the Rorschach Inkblot Test.
- Images a viewer say in blot seemed to correspond w/ his/her psychological condition

What is neuroimaging? Examples?
Neurological tests that provide images of brain structure or activity
- CAT scan
- PET scan
- MRI
What is a CAT scan?
- Computerized axial tomography
- Xrays of the brain’s structure are taken at diff angles and combined
What is a PET scan?
- Positron emission tomography
- Computer-produced motion picture of chemical activity throughout the brain
What is an MRI?
- Magnetic resonance imaging
- Procedure that uses the magnetic property of certain hydrogen atoms in the brain to create a detailed picture of the brain’s structure
What are neuropsychological tests?
Tests that detect brain impairment by measuring a person’s cognitive, perceptual, and motor performances
Describe the Bender Gestalt Test.
- Consists of 9 cards, each displaying a simple geometric design
- Patients copy down each one
- Later, patients redraw them from memory
Describe the Complex Figure Test.
- Asked to copy a complex figure
- Good for finding specific parts of the brain that are impaired
