Question

Quizplus · Accepted Answer

Psychophysics is the branch of psychology concerned with the relationship between physical stimuli and psychological experiences. It examines how physical events are translated into psychological experiences, such as sensation, perception, and cognition.

Answer: B
 Psychophysics is concerned with the relationship between physical events and psychological experiences, specifically the quantification of this relationship. This includes the measurement of the intensity of a stimulus and how it is perceived by an individual.

Answer: C
 Weber's law is a principle of psychophysics that states that the just noticeable difference (JND) between two stimuli is proportional to the magnitude of the reference stimulus. This constant ratio between the stimulus threshold and reference stimulus is known as Weber's fraction.

Answer: D
 Perception is the process by which sensations are organized and interpreted to form an internal representation of the world. Psychophysics plays a role in this process by examining the relationship between physical stimuli and the resulting perceptual experience.
