Read the text below and answer the question: A subject, sometimes in a room isolated from the scientist, would receive a stimulus such as a light, image, or sound. The subject’s reaction to the stimulus would be to push a button, and an apparatus would record the time to reaction. The experimenters could measure reaction time to one-thousandth of a second. They also interviewed the subject about their feelings and reactions. However, despite their efforts to train individuals, this process remained highly subjective, and there was very little agreement between individuals. Question: What is the name of this approach to psychology?
