Each functional component of an umwelt has a meaning that represents the organism's model of the world. These functional components correspond approximately to perceptual features, [5] as described by Anne Treisman. It is also the semiotic world of the organism, including all the meaningful aspects of the world for any particular organism. It ...
Cognitive maps Some animals appear to construct a cognitive map of their surroundings, meaning that they acquire and use information that enables them to compute how far and in what direction to go to get from one location to another. Such a map-like representation is thought to be used, for example, when an animal goes directly from one food ...
Multimodal perception is how animals form coherent, valid, and robust perception by processing sensory stimuli from various modalities. Surrounded by multiple objects and receiving multiple sensory stimulations, the brain is faced with the decision of how to categorize the stimuli resulting from different objects or events in the physical world.
Vision dominates our perception of the world around us. This is because visual spatial information is one of the most reliable sensory modalities. Visual stimuli are recorded directly onto the retina, and there are few, if any, external distortions that provide incorrect information to the brain about the true location of an object. [18]
Helmholtz theorized that perceptual adaptation might result from a process he referred to as unconscious inference, where the mind unconsciously adopts certain rules in order to make sense of what is perceived of the world. An example of this phenomenon is when a ball appears to be getting smaller and smaller, the mind will then infer that the ...
During early development, infants begin to crawl, sit, and walk. These actions impact how the infants view depth perception. Thus, infant studies are an important part of the visual cliff. When an infant starts to engage in crawling, to sit, or walking, they use perception and action. During this time, infants begin to develop a fear of height.
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).

A perceptual system is a computational system (biological or artificial) designed to make inferences about properties of a physical environment based on scenes. Other definitions may exist. Other definitions may exist.
