Quizplus · Accepted Answer

Psychophysics is the branch of psychology that deals with the relationship between physical stimuli and psychological responses. Therefore, a psychophysicist is most likely to be interested in understanding how physical stimuli (such as sound, light, touch) are perceived and interpreted by the brain. Option D asks how much louder a sound must be before it can be detected, which is a question about perceptual thresholds and falls within the scope of psychophysics. Options A and B are more relevant to neurophysiology, while option C is more relevant to cognitive psychology.
