SensationThe physical process during which our sensory organs (e.g., eyes, ears, nose among others) respond to external stimuli is called sensation. Sensation happens when you eat noodles or feel the wind on your face or hear a car horn honking in the distance. During sensation, our sense organs are engaging in transduction, the conversion of one form of energy into another. For example, physical energy such as light or a sound wave is converted into a form of electrical energy that the brain can understand. PerceptionAfter our brain receives the electrical signals we make sense of all this stimulation and begin to appreciate the complex world around us. This psychological process, making sense of the stimuli, is called perception. It is during this process that you are able to identify a gas leak in your home, recognize the color orange, or connect a song that reminds you of a specific afternoon spent with friends. Perception is the process of interpreting and organizing the information that we received from our senses. Our experience influences how our brain processes information. You have tasted food that you like and food that you don’t like. There are some bands you enjoy and others you can’t stand. When eat something new or hear a new band, you process those stimuli using bottom-up processing. This is when we build up to perception from the individual pieces. Sometimes stimuli we’ve experienced in our past will influence how we process new ones. This is called top-down processing. The best way to illustrate these two concepts is with our ability to read. Read the following quote out loud:  Notice anything odd while you were reading the text in the triangle? Did you notice the second “the”? If not, it’s likely because you were reading this from a top-down approach. Having a second “the” doesn’t make sense. We know this and our brain knows this and doesn’t expect there to be a second one, so we tend to skip right over it. In other words, your past experience has changed the way you perceive the writing in the triangle. Someone who is just learning to read is using a bottom-up approach by carefully attending to each piece and would be less likely to make this error. Sensation and perception are interrelated processes that are developed throughout the lifespan. Although they have a close relationship, sensation and perception have discrete qualities that differentiate one from the other.

The physical stimulus present in the environment emits energy that is absorbed by a sensory organ (known as transduction), causing sensation. PerceptionPerception refers to the occurrence when the brain performs organization of information it obtains from the neural impulses, and then begins the process of translation and interpretation. It is a vital 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, etc. RelationshipSensation and perception are elements that balance and complement one another. They work together for us to be able to identify and create meaning from stimuli-related information. Without sensation, perception will not be possible, except for people who believe in extrasensory perception or ESP. And without perception, our sensations would remain to be "unknown" to us since there is no mental processing of what we sense. DifferencesSensation and perception are two completely different elements in terms of how they process information. In sensation, the physical stimulus, together with its physical properties, is registered by sensory organs. Then, 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 is able to "make sense" out of the sensations. For instance, seeing the light (sensation) is different from determining its color (perception). Another example is that feeling the coldness of the environment is different from perceiving that winter is coming. Also, hearing a sound is different from perceiving the music being played. Most psychologists believe that sensation is an important part of bottom-up processing. This means that sensation occurs when the sensory organs transmit information towards the brain. On the other hand, perception is a part of top-down processing. In this case, perception happens when the brain interprets the sensory information and sends corresponding signals to sensory organs for response to the physical stimuli. What type of process is sensation?The physical process during which our sensory organs—those involved with vision and hearing, for example—respond to external stimuli is called sensation.
Is sensation a mental process?Though the process of sensing is thought by some to be purely mental, some psychologists and philosophers hold that what is sensed is normally a physical quality existing independently of mind: e.g., the grass is literally green whether or not any person is present to perceive it.
What is sensation process in psychology?Sensation is the process by which we receive, transform, and process stimuli that impinge on our sensory organs into neural impulses, or signals, that the brain uses to create experiences of vision, hearing, taste, smell, touch, and so on.
What is a mental sensation?Description: This is the sensation which follows immediately the sensation of an outer sense, or pure sensation, and is evoked by it. It is an intelligible sensation, direct, intuitive and non-conceptive. Constructive imagination is excluded here, so the sensation is incapable of illusion.
