Question

Quizplus · Accepted Answer

The physiological measurement technique that measures muscle contractions in areas of the face when emotionally charged stimuli are encountered is facial electromyography (EMG). This technique can be used to measure the activity of specific muscles, such as those involved in smiling or frowning, and is often used in studies on emotions and facial expressions. Facial EEG measures electrical activity in the brain, facial PET measures brain activity using positron emission tomography, and facial MRI is a type of imaging that can be used to visualize structures in the face but does not measure muscle activity.
