Question

Quizplus · Accepted Answer

Psychophysics is the study of the relationship between physical stimuli and our psychological experiences of them, including perception and sensation. In this case, Brenda is being asked to make judgments about the brightness of lights, which falls within the realm of psychophysics. Anthropometry is the study of measuring the human body and its features, phrenology is an outdated pseudoscientific practice of trying to determine personality traits based on the shape of the head, and eugenics is a controversial and unethical practice of trying to improve the human race through selective breeding or other means. None of these choices are relevant to Brenda's task of identifying the brightest light.
