This discrepancy constituted some of the basis of the controversy on human recommended dietary allowances being set too low. [81] However, simian consumption does not indicate simian requirements. Merck's veterinary manual states that daily intake of vitamin C at 3–6 mg/kg prevents scurvy in non-human primates. [82]
In probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time if these events occur with a known constant mean rate and independently of the time since the last event.

The observation of sub-wavelength structures with microscopes is difficult because of the Abbe diffraction limit.Ernst Abbe found in 1873, [2] and expressed as a formula in 1882, [3] that light with wavelength , traveling in a medium with refractive index and converging to a spot with half-angle will have a minimum resolvable distance of
Eidetic memory (/ aɪ ˈ d ɛ t ɪ k / eye-DET-ik), also known as photographic memory and total recall, is the ability to recall an image from memory with high precision—at least for a brief period of time—after seeing it only once [1] and without using a mnemonic device.
The human auditory system is most sensitive to frequencies between 2,000 and 5,000 Hz. [10] Individual hearing range varies according to the general condition of a human's ears and nervous system. The range shrinks during life, [11] usually beginning at around the age of eight with the upper frequency limit being reduced. Women lose their ...
Many of the familiar picture absurdities, vocabulary, memory for sentences, and verbal absurdities still remain from the previous editions (Janzen, Obrzut, & Marusiak, 2003), however with more modern artwork and item content for the revised fifth edition.
Mathematical psychology is an approach to psychological research that is based on mathematical modeling of perceptual, thought, cognitive and motor processes, and on the establishment of law-like rules that relate quantifiable stimulus characteristics with quantifiable behavior (in practice often constituted by task performance).
Defining and measuring sensory thresholds requires setting the sensitivity limit such that the perception observations lead to the absolute threshold. The level of sensitivity is usually assumed to be constant in determining the threshold limit. There are three common methods used to determine sensory thresholds: [2] Method of Limits:
