Final answer:
Sensory adaptation is the process in which our perception of a stimulus decreases over time if the stimulus remains constant.
Step-by-step explanation:
Sensory adaptation is the process in which our perception of a stimulus decreases over time if the stimulus remains constant. The stimulus needs to be altered in order for our perception to change.
