Sensation and Perception is a popular sub-field within the broader field of psychology. Sensation: Perception: The sensation is the first stage of a complex process that allows us to understand and interact with our world. In other words, sensation involves detecting the presence of a stimulus whereas perception involves understanding what the stimulus means. Current Opinion in Neurobiology, 4, 157–165. For example, when we see something, the visual stimulus is the light energy reflected from the external world and the eye becomes the sensor.

Perceptions allow people to create meaningful patterns out of the sensations they experience. We use this information to successfully navigate and interact with our environment so that we can find nourishment, seek shelter, maintain social relationships, and avoid potentially dangerous situations. One way to think of this concept is that sensation is a physical process, whereas perception is psychological. Ungerleider, L. G., & Haxby, J. V. (1994). Visual sensing without seeing. Without sensation, perception will not be possible, except for people who believe in extrasensory perception or ESP.

Cognitive Psychology: Sensation and Perception As adaptive creatures, we humans need to know what is happening in the world around us. The ability to take in information from reality and process it in meaningful ways allows people to form a worldview that helps them to understand life and make wise decisions. Stimulus information from our environment is frequently ambiguous so to interpret it, we require higher cognitive information either from past experiences or stored knowledge in order to makes inferences about what we perceive. Sensation is a signal from any of our six senses. A perception failure leads to misinterpretation of life and an inability to respond adequately to the current situation. A perception failure leads to misinterpretation of life and an inability to respond adequately to the current situation. A lack or loss of sensations, such as blindness or deafness, creates a gap in the experience and makes it harder to understand events fully. Segall, M. H., Campbell, D. T., & Herskovits, M. J.

Sensation is passively receiving information through sensory inputs, and perception is interpreting this information. Garland, E. L. (2012). A theoretical approach developed by Wilhelm Wundt, structuralism is a theory that claimed sensations as individual elements that add up to create perceptions. Hartline, P. H., Kass, L., & Loop, M. S. (1978). In psychology, perception is called a unified consciousness derived from the sensory processes while a stimulus is present. Gestalt theory describes four ways that the brain groups similar objects to make sense of them: similarity (grouping like objects), proximity (grouping objects that are near each other), continuity (recognizing patterns) and closure (filling in gaps in familiar shapes or patterns).
