Dr.Mills measures participants' brain-wave activity in order to study the brain's response to sounds of varying frequencies.Dr.Mills is likely to be using which type of physiological measure?
A) GSR (galvanic skin response)
B) EMG (electromyogram)
C) EEG (electroencephalogram)
D) EKG (electrocardiogram)

Quizplus · Accepted Answer

EEG (electroencephalogram) measures brain-wave activity and is commonly used in studies of the brain's response to sensory stimuli such as sound. GSR (galvanic skin response) measures changes in the electrical conductivity of the skin, often used in studies of emotional arousal. EMG (electromyogram) measures muscle activity and is used in studies of movement and muscle tension. EKG (electrocardiogram) measures heart rate and rhythm and is used in studies of cardiovascular function.
