Question

multiple choice question
the energy that produces a response in the sense organs is called a ______.

○ stimulus.
○ sensation.
○ psychophysic.
○ perception.

Explanation:

To solve this, we analyze each option:

• stimulus: Defined as energy (or a thing) that elicits a response from sense organs/sensory systems. This matches the question's description.
• sensation: Is the response (perception) of sense organs, not the energy causing it. Eliminate.
• psychophysic: (Likely "psychophysics") Is the study of the relationship between physical stimuli and psychological sensations, not the stimulus itself. Eliminate.
• perception: Is the interpretation of sensory information, not the energy triggering it. Eliminate.

Answer:

A. stimulus.
