To Investigate Differences in the Brain Functioning of Individuals with an Impulsive

To investigate differences in the brain functioning of individuals with an impulsive personality in comparison to those individuals with a non-impulsive personality, Professors Sweet and Ayr measure the amount of energy-providing substances (e.g., sugar and oxygen) used in the brain cells of these individuals by comparing video images of their brains while having them play a highly violent military combat video game. In this research, they are using the _________ technique to measure brain activity.

A) Electrodermal (EDM)
B) Galvanic (gVal)
C) Functional magnetic resonance imagining (fMRI)
D) Electroencephalograph (EEG)
E) Positron emission tomography (PET)
