The sensation is specifying as the process in which a sensory receptor is stimulated, producing nerve impulses that travel to the brain, which in turn interprets such impulses as a visual image, a sound, taste, odor, touch, or pain. The physical stimulus present in the environment transmit energy that is absorbed by a sensory organ (known as transduction), causing a sensation. Perception refers to the instance when the brain performs the organization of information it obtains from the neural impulses and then begins the process of translation and interpretation. Therefore, it is a basic process that helps us rationalize or make sense of the information related to the physical stimulus. Perception occurs when the brain processes information to give meaning to it, by means of emotions, memories (Sincero,2013).

   Sensation and perception are two completely different components in terms of how they process information. In sensation, the physical stimulus, together with its physical properties, is registered by sensory organs. suddenly, the organs decode this information and transform them into neural impulses or signals. These signals are transmitted to the sensory cortices of the brain. The line of difference between sensation and perception is now drawn; perception follows sensation. In the brain, the nerve impulses go through a series of organization, translation, and interpretation. Once perception is finished, a person can “make sense” out of the sensations. Comparatively, seeing the light (sensation) is different from determining its color (perception). One more example is that feeling the coldness of the environment is different from perceiving that winter is coming. Besides, hearing a sound is different from perceiving the music being played (Sincero,2013).

   we can experience a sensation without perception, but without sensation there can be no perception. However, we can define the two terms in the following aspect. The word ‘sensation’ can be characterized as the process of using sense through touch, smell, sight, sound, and taste. On the other hand, the word ‘Perception’ can be defined as the way we interpret the world through our senses. This is the vital difference between the two words. Despite, one must take in mind that Sensation and Perception must be viewed as two processes that correlative to one another, rather than two unrelated processes.
