[3] [8] This raw pattern of neural activity is called the proximal stimulus. [3] These neural signals are then transmitted to the brain and processed. [3] The resulting mental re-creation of the distal stimulus is the percept. To explain the process of perception, an example could be an ordinary shoe. The shoe itself is the distal stimulus.
The term originates with René Descartes in the form of the word apercevoir in his book Traité des passions. Leibniz introduced the concept of apperception into the more technical philosophical tradition, in his work Principes de la nature fondés en raison et de la grâce; although he used the word practically in the sense of the modern attention, by which an object is apprehended as "not ...
The ability to perceive the world in three dimensions and estimate the size and distance to an object depends heavily on depth cues. The two major depth cues, stereopsis and motion parallax, both rely on parallax which is the difference between the perceived position of an object given two different viewpoints.
Emotion perception refers to the capacities and abilities of recognizing and identifying emotions in others, in addition to biological and physiological processes involved. . Emotions are typically viewed as having three components: subjective experience, physical changes, and cognitive appraisal; emotion perception is the ability to make accurate decisions about another's subjective ...
A 3 D model, where the scene is visualized in a continuous, 3-dimensional map. [36] Marr's 2 1 ⁄ 2 D sketch assumes that a depth map is constructed, and that this map is the basis of 3D shape perception. However, both stereoscopic and pictorial perception, as well as monocular viewing, make clear that the perception of 3D shape precedes, and ...
Active perception is the selecting of behaviors to increase information from the flow of data those behaviors produce in a particular environment. In other words, to understand the world, we move around and explore it—sampling the world through our senses to construct an understanding (perception) of the environment on the basis of that behavior (action).

Depth perception is the ability to perceive distance to objects in the world using the visual system and visual perception. It is a major factor in perceiving the world in three dimensions Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known ...
