John is participating in an experiment that is designed to determine how much brighter a light has to be before he perceives the magnitude as twice as bright as the original light. Jane is participating in an experiment to determine how strong an odor has to be before she initially perceives the odor. The experiment in which John is participating relates to the question and the experiment in which Jane is participating relates to the question.

John is participating in scaling; Jane is participating in a detection experiment question.

Explanation:

The experiment in which John is participating relates to the scaling question and the experiment in which Jane is participating relates to the detection question.

Scaling questions is a method used to construct understandings in order to assess a variable, situation, concern, relationship etc, it involved participant by asking them to perceive, described a variable based on a continuum i.e to rate, grade, usually based a scale of preference. John in the experiment was asked to determine how much brighter light has to be which is based on how he perceives the magnitude of the original light, the researcher is simply asking John to scale the light magnitude.

Detection questions are usually in an interrogative form used to exploring and searching for quality information; a technique that estimates detectability of the observer to accurately detect stimuli or a situation. Jane participating in an experiment was asked to determine how strong an odor has to be before she initially perceives the odor.

if im not mistaken its a. collective emotional arousal
