Scenario I
A psychologist interested in studying visual perception manipulates the brightness of a light in the imperceptible to very dim range. Each level of brightness (measured in lumens) is studied for 10 trials, and on each trial participants are asked if they can detect the light. Figure 4.1 shows hypothetical data from one participant.

Quizplus · Accepted Answer

This scenario involves manipulating the brightness of a light and studying participants' perception of it, which falls under the field of psychophysics. Psychophysics specifically studies the relationship between physical stimuli (such as the brightness of a light) and their perception by an individual.
