PSY 402 Topic 1 DQ 1

The topics of sensation and perception are among the oldest and most important in all of psychology. People are equipped with senses such as sight, hearing and taste that help us to take in the world around us. Amazingly, our senses have the ability to convert real-world information into electrical information that can be processed by the brain. The way we interpret this information– our perceptions– is what leads to our experiences of the world. In this module, you will learn about the biological processes of sensation and how these can be combined to create perceptions.Sensation and Perception Assignment Paper

Perception 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.

Relationship

Sensation 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.

Differences

Sensation 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.Sensation and Perception Assignment Paper

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.Sensation and Perception Assignment Paper
