  2. Numerical cognition - Wikipedia

    en.wikipedia.org/wiki/Numerical_cognition

    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.

  3. Numerical Stroop effect - Wikipedia

    en.wikipedia.org/wiki/Numerical_Stroop_effect

    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.

  4. Just-noticeable difference - Wikipedia

    en.wikipedia.org/wiki/Just-noticeable_difference

    The total number of perceptible pitch steps in the range of human hearing is about 1,400; the total number of notes in the equal-tempered scale, from 16 to 16,000 Hz, is 120. [ 9 ] In speech perception

  5. Perception - Wikipedia

    en.wikipedia.org/wiki/Perception

    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]

  6. Number sense - Wikipedia

    en.wikipedia.org/wiki/Number_sense

    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]

  7. Approximate number system - Wikipedia

    en.wikipedia.org/wiki/Approximate_number_system

    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]

  8. Precision and recall - Wikipedia

    en.wikipedia.org/wiki/Precision_and_recall

    To calculate the recall for a given class, we divide the number of true positives by the prevalence of this class (number of times that the class occurs in the data sample). The class-wise precision and recall values can then be combined into an overall multi-class evaluation score, e.g., using the macro F1 metric. [21]

  9. Stevens's power law - Wikipedia

    en.wikipedia.org/wiki/Stevens's_power_law

    In magnitude estimation with a standard, the experimenter presents a stimulus called a standard and assigns it a number called the modulus. For subsequent stimuli, subjects report numerically their perceived intensity relative to the standard so as to preserve the ratio between the sensations and the numerical estimates (e.g., a sound perceived ...
