Numerical cognition is a subdiscipline of cognitive science that studies the cognitive, developmental and neural bases of numbers and mathematics.As with many cognitive science endeavors, this is a highly interdisciplinary topic, and includes researchers in cognitive psychology, developmental psychology, neuroscience and cognitive linguistics.
Perception (from Latin perceptio 'gathering, receiving') is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. [2]
In non-human animals, number sense is not the ability to count, but the ability to perceive changes in the number of things in a collection. [5] All mammals, and most birds, will notice if there is a change in the number of their young nearby. Many birds can distinguish two from three. [6]
Examining the representation of numerosity in animals is a challenging task, since it is not possible to use language as a medium. Because of this, carefully designed experimental setups are required to differentiate between numerical abilities and other phenomena, such as the Clever Hans phenomenon, memorization of the single objects or perception of object size and time.
For example, if a stimulus is tripled in strength (i.e., 3 × 1), the corresponding perception may be two times as strong as its original value (i.e., 1 + 1). If the stimulus is again tripled in strength (i.e., 3 × 3 × 1), the corresponding perception will be three times as strong as its original value (i.e., 1 + 1 + 1). Hence, for ...

The approximate number system (ANS) is a cognitive system that supports the estimation of the magnitude of a group without relying on language or symbols. The ANS is credited with the non-symbolic representation of all numbers greater than four, with lesser values being carried out by the parallel individuation system, or object tracking system. [1]
The numerical Stroop effect, a concept rooted in cognitive psychology, refers to the interference that occurs when individuals are asked to compare numerical values or physical sizes of digits presented together. The effect arises when there is a mismatch—or incongruity—between the numerical value and the physical size of the digits.
