Final answer:
Normal visual sensation accompanied by incomplete visual perception is best illustrated by sensory adaptation. Sensory adaptation occurs when we become less sensitive to a constant or unchanging stimulus over time.
Step-by-step explanation:
Normal visual sensation accompanied by incomplete visual perception is best illustrated by sensory adaptation. Sensory adaptation occurs when we become less sensitive to a constant or unchanging stimulus over time. An example of sensory adaptation is when we no longer notice the flashing light outside our window after a while, even though our eyes still sense the light. Sensory adaptation demonstrates that sensation and perception are different processes.
