The brightness constancy keeps the brightness property of an object constant irrespective of how light or dark the surrounding is.Licenses and Attributions (Click to expand) The physical process during which our sensory organsthose involved with vision and hearing, for examplerespond to external stimuli is called sensation. Perception is the process by which we give meaning to sensory info i.e. Similarly, shape constancy ensures the fact that the shape of an object does not change even if the viewpoint of the object stands different and multiple. The fact that different viewpoint does not change the size of the object is the principle of a perceptual process known as size constancy. These different viewpoints of the object do not change the size of the object or the image. It is how we find the meaning in the world. When we view an object, the angles of the view could be multiple. Sensation differs from the idea of perception because perception is how the brain interprets the world around us. One way to think of this concept is that sensation is a physical process, whereas perception is psychological. These perceptual constancies are size constancy, shape constancy, and brightness constancy. These constancies do not change irrespective of how the stimuli of the object being viewed are taken in. Such perceptions could be increased, decreased, or distorted with the patients hearing, vision, touch sensation, smell, or kinesthetic responses to stimuli. Certain elements of perceptual processes are constant. In the generic sense of the term, perception refers to the use of our five senses (sight, hearing, smell, taste, touch) to gather sensory information for organization, interpretation and experiences. Sensory-perceptual alteration can be defined as when there is a change in the pattern of sensory stimuli followed by an abnormal response to such stimuli. Mechanical, chemical, or thermal stimuli beyond a set threshold will elicit painful sensations. Perception is that natural filter attached in our brain that allows us to meaningfully interpret the world which helps us to exist without being overwhelmed by an abundance of information and stimuli. Nociception is the sensation of potentially damaging stimuli. When the sensory organs send external stimuli to the brain and transduction takes place, where the external stimuli are converted into neural signals and in turn, these neural signals are taken out in the form of perception. Perception is the method by which the brain takes in all the information from the environment through the sensory organs or the senses and takes out the information allowing the individual to form a systematic and meaningful interpretation of the same. In a similar manner, olfaction is the sense of smell that takes place through the receptors in the nose and creates neural signals which go to the olfactory bulbs in the brain.Somesthetic sense includes the senses that place in the skin also known as kinesthetic sense. ![]() Gustation is the sense of taste which takes place in the taste buds located in the tongue. While sensation is the process of sensory input arriving at the cerebral cortex, perception is the brain making sense of this input. ![]() Auditory perception takes place when sounds in the form of vibrations travel through the ears, sends signals to the brain, and perception of sound takes place. Mechanoreceptors in the inner ear turn vibration motion into electrical nerve pulses. The eyes then send the vision of the object in the form of signals of light to the brain and the brain as a result creates the picture in the mind. ![]() In order to see any object, the light must get reflected from this object source and travel through the retina of the eyes. But when the external stimuli are unchanging from a long period of time, sensory adaptation takes place in the form of habituation. This process of converting external stimuli into a neural signal is called transduction. The sensory receptors allow these stimuli to become neural signal after getting into the brain. Our perceptions influence how we focus on, process, remember, interpret, understand, synthesize, decide about, and act on reality. Sensation takes place when the special receptors located in the sensory organs – eyes, ears, nose, tongue, and skin are activated. The sensation is something that makes an individual aware of the stimuli, whereas perception gives meaning to the stimuli. Perception acts as a lens through which we view reality.
