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. In this context, a scene is defined as sensory information that can flow from a physical environment into a computational system via sensory transduction.
Barsalou's research addresses the nature of human conceptual processing and its roles in perception, memory, language, thought, social interaction, and health cognition. [2] Across domains, much of this work focuses on the impact of goals and environmental context on cognitive processing, as well as how multimodal simulation, situated ...
Goodale and Milner [2] amassed an array of anatomical, neuropsychological, electrophysiological, and behavioural evidence for their model. According to their data, the ventral 'perceptual' stream computes a detailed map of the world from visual input, which can then be used for cognitive operations, and the dorsal 'action' stream transforms incoming visual information to the requisite ...
As early as the 1860s, with the work of Hermann Helmholtz in experimental psychology, the brain's ability to extract perceptual information from sensory data was modeled in terms of probabilistic estimation. [5] [6] The basic idea is that the nervous system needs to organize sensory data into an accurate internal model of the outside world.
For example, the perceptual expertise of a baseball player at bat can detect early in the ball's flight whether the pitcher threw a curveball. However, the perceptual differentiation of the feel of swinging the bat in various ways may also have been involved in learning the motor commands that produce the required swing. [1]
Perceptual psychology is a subfield of cognitive psychology [1] that concerns the conscious and unconscious innate aspects of the human cognitive system: perception. [2] A pioneer of the field was James J. Gibson. One major study was that of affordances, i.e. the perceived utility of objects in, or features of, one's surroundings. According to ...
Conclusions have been drawn from preferential looking experiments about the knowledge that infants possess. For example, if infants discriminate between rule-following and rule-violating stimuli — say, by looking longer, on average, at the latter than the former — then it has sometimes been concluded that infants know the rule.
