RESEARCH METHODS

• Weighing wet brains at autopsy
• Measuring empty skull volume with a filler
• Measuring external head size and estimating volume
• Computer assisted tomography (CAT)
• Magnetic resonance imaging (MRI)

OTHER RESEARCH FACTORS

• Kin selection, a tool used by Rushton and other scientist.
• Kin selection - when another has similar genetic traits and it is the reason for acceptance.
• Tool - Reaction time measures:
• Simple reaction time, choice reaction time, odd-man-out reaction time.
• These are tests that require no training and can be completed in under a second.
