________ tests are used to detect changes in the brain and nervous system that reflect emotional and psychological changes.These tests are alternative methods to magnetic resonance imaging (MRIs) , computerized tomography (CT) , positron-emission tomography (PET) , and single photon emission computed tomography (SPECT) .

A) Psychophysiological
B) Neuropsychological
C) Personality
D) Projective

Psychophysiological tests, such as electroencephalograms (EEGs) and skin conductance tests, measure changes in bodily functions in response to emotional and psychological stimuli. They are not used to directly visualize the brain and nervous system like MRI, CT, PET, and SPECT, but rather measure the physiological responses that reflect changes in those systems. Neuropsychological tests measure cognitive functioning and assess brain damage or dysfunction, but do not necessarily reflect emotional and psychological changes. Personality and projective tests measure traits, attitudes, and behaviors, but also do not directly assess changes in the brain and nervous system.
