Sensation is the physical process of collecting data from the environment. Sensory receptors (in the eyes, ears, nose, tongue, and skin) detect physical energy—such as light waves or sound vibrations—and convert it into neural signals.

The environment or surrounding stimuli can change how we perceive an object (e.g., a tall person looks average next to a professional basketball player). 5. Conclusion
