In this last stage of perceptive process, meaning is assigned to the organized stimulus. Interpretation and assigning meaning to the stimuli is based on one's own experiences, expectations, needs, beliefs, other's experiences and other factors. This stage is subjective in nature and the same stimuli can be interpreted differently by different individuals.

Although our perceptions are built from sensations, not all sensations result in perception. In fact, we often don’t perceive stimuli that remain relatively constant over prolonged periods of time. This is known as sensory adaptation.<ref name=":0" />

Imagine entering a classroom with an old analog clock. Upon first entering the room, you can hear the ticking of the clock; as you begin to engage in conversation with classmates or listen to your professor greet the class, you are no longer aware of the ticking. The clock is still ticking, and that information is still affecting sensory receptors of the auditory system. The fact that you no longer perceive the sound demonstrates sensory adaptation and shows that while closely associated, sensation and perception are different.<ref name=":0" />

Imagine a person entering a classroom having an old analog clock. Upon first entering the room, he can hear the ticking of the clock; as he engages in conversation with classmates or listens to professor greet the class, he shall no longer be aware of the clock ticking. The clock continues to tick, and that stimulus continues to affect the sensory receptors of the person's auditory system even as time passes. The fact that he no longer perceives the sound demonstrates sensory adaptation and shows that while closely associated, sensation and perception are different.<ref name=":0" />

=== Attention ===

Attention plays a significant role in determining what is sensed versus what is perceived. Imagine you are at a party full of music, chatter, and laughter. You get involved in an interesting conversation with a friend, and you tune out all the background noise. If someone interrupted you to ask what song had just finished playing, you would probably be unable to answer that question.<ref name=":0" />

Failure to notice something that is completely visible because of a lack of attention is called inattentional blindness.<ref name=":0" />
