Perceptual constancy can be explained as the ability or tendency of perceiving or seeing a familiar object ah having constant or standard shape or size despite or regardless of the distance of the object.
Perceptual constancy has three types , which are
* Shape constancy
* Size constancy
* Brightness constancy
In the case of Immanuel, he was able to know that the kite is not shrinking despite the distance, this is because his brain has the ability of maintaining perceptual constancy.
Perceptual constancy, is also know as Object Constancy, or Constancy Phenomenon. It is the ability of the brain to view perception of objects not minding the variations in retinal image when an object adjusts position or distance from the viewer. It helps animals and humans to view familiar objects as possessing standard shape, size, colour, or location irrespective of variations in the angle of perspective, distance, or lighting despite the fact that the illumination and retinal images may vary.
Another example is the distance between a door and an individual such that no matter the distance between a door and a person, the person still perceive it as possessing a constant size.
Peroxisomes are the membrane-bound organelles present in eukaryotic cells only. These are specifically abundant in liver cells and are involved in the breakdown of fatty acids. Peroxisomes have enzymes that catalyze metabolic reactions in which hydrogen from various compounds is transferred to oxygen. These reactions produce hydrogen peroxide. Catalase is the enzyme present in peroxisomes that rapidly splits excess hydrogen peroxide to water and oxygen, rendering it harmless.
