Such findings aforementioned studies show that biological motion perception is a process that pulls in several different neural systems outside of networks involved in the visual processing of non-biological motions and objects.
Perceptual categorization is said to occur when a person or animal responds in a similar way to a range of stimuli that share common features. For example, a squirrel climbs a tree when it sees Rex, Shep, or Trixie, which suggests that it categorizes all three as something to avoid. This sorting of instances into groups is crucial to survival.
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.
The estimated sensory feedback can be used to alter an animal's perception related to self-generated motion. [3] The difference between the expected sensory state and sensory feedback can be used to correct errors in movement and the model. [3]
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 ...
Feature detection is a process by which the nervous system sorts or filters complex natural stimuli in order to extract behaviorally relevant cues that have a high probability of being associated with important objects or organisms in their environment, as opposed to irrelevant background or noise.
A perceptual set (also called perceptual expectancy or simply set) is a predisposition to perceive things in a certain way. [105] It is an example of how perception can be shaped by "top-down" processes such as drives and expectations. [106] Perceptual sets occur in all the different senses. [62]
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.
