Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment.
Commonly recognized sensory systems are those for vision, hearing, touch, taste, smell, balance and visceral sensation. Sense organs are transducers that convert data from the outer physical world to the realm of the mind where people interpret the information, creating their perception of the world around them.
For example, information from one sense has the potential to influence how information from another is perceived. [7] Sensation and perception are studied by a variety of related fields, most notably psychophysics, neurobiology, cognitive psychology, and cognitive science.
Alliesthesia (from Ancient Greek: ἀλλοῖος, romanized: alloios – be changed, and αἴσθησις (aísthēsis) – sensation, perception; thus "changed sensation"; French: alliesthésie, German: Alliästhesie) is a psychophysiological phenomenon (not to be confused with the pathologic symptom of allesthesia) that describes the ...
[4] [5] Sensory input is a process that transforms this low-level information to higher-level information (e.g., extracts shapes for object recognition). [5] The following process connects a person's concepts and expectations (or knowledge ) with restorative and selective mechanisms, such as attention , that influence perception.
Subsequently, however, the sensation of the table surface against the skin gradually diminishes until it is virtually unnoticeable. The sensory neurons that initially respond are no longer stimulated to respond; this is an example of neural adaptation.
Other spatial information is not as reliable as visual spatial information. For example, consider auditory spatial input. The location of an object can sometimes be determined solely on its sound, but the sensory input can easily be modified or altered, thus giving a less reliable spatial representation of the object.

Iconic memory, for example, holds visual information for approximately 250 milliseconds. [7] The SM is made up of spatial or categorical stores of different kinds of information, each subject to different rates of information processing and decay. The visual sensory store has a relatively high capacity, with the ability to hold up to 12 items. [8]
