What is the practice that studies the shape and size of the cranium as an indication of character and mental abilities?

• A. EEG
• B. MRI
• C. Angiography
• D. Phrenology

Answer: (D)

Phrenology is the practice that studies the shape and size of the cranium as an indication of character and mental abilities. It originated with the idea that bumps and contours on the skull reflect distinct brain regions responsible for specific traits and talents, so by feeling the skull you could infer personality and intellect. Modern science does not support this link; skull morphology does not reliably correspond to how the brain is organized or what it can do, and personality or cognitive abilities aren’t read from skull shape. Other techniques mentioned assess brain activity, structure, or vasculature directly—electrical activity with EEG, detailed brain imaging with MRI, or blood vessels with angiography—rather than inferring character from skull features. Phrenology is now considered a historical and discredited approach.
