A. cerebral asymmetry.
B. brain damage.
C. temperament.
D. classical conditioning.
Question 2Which of the following has been found by researchers examining cerebral asymmetry?
A. When most people experience positive emotions, they have higher levels of electrical activity in their right hemisphere.
B. Most people have more electrical activity in the left hemisphere than the right hemisphere.
C. Changes in electrical activity can be detected when people experience negative emotions, but not when they experience positive emotions.
D. Differences in hemispheric activity levels can be detected in children less than one year old.
Question 3Psychologists have found that using an electroencephalograph (EEG) in their research has all the advantages listed below except one. Which one?
A. The EEG allows researchers to record brain activity in quick intervals.
B. The EEG electrodes only pierce the scalp in a few places, and participants recover from the procedure after only a few days.
C. Participants report that the procedure is not uncomfortable.
D. The EEG can measure brain activity level in more than one part of the brain.
Question 4A psychologist wants to conduct research on cerebral asymmetry. She wants to examine
A. brain damage.
B. intelligence.
C. mental retardation.
D. differences in right- and left-hemisphere activity.
Question 5A psychologist purchases an electroencephalograph (EEG) for use in his research. The psychologist is interested in measuring
A. intelligence.
B. muscle tension.
C. heart rate.
D. brain-wave activity.
