This identity is derived from the divergence theorem applied to the vector field F = ψ ∇φ while using an extension of the product rule that ∇ ⋅ (ψ X) = ∇ψ ⋅X + ψ ∇⋅X: Let φ and ψ be scalar functions defined on some region U ⊂ R d, and suppose that φ is twice continuously differentiable, and ψ is once continuously differentiable.
Four Fs (evolution) In evolutionary psychology, people often speak of the four Fs which are said to be the four basic and most primal drives (motivations or instincts) that animals (including humans) are evolutionarily adapted to have, follow, and achieve: fighting, fleeing, feeding and mating (a more polite synonym of the word "fucking").

Biological basis of personality. The biological basis of personality is a collection of brain systems and mechanisms that underlie human personality. Human neurobiology, especially as it relates to complex traits and behaviors, is not well understood, but research into the neuroanatomical and functional underpinnings of personality are an ...
Tinbergen's four questions. Tinbergen's four questions, named after 20th century biologist Nikolaas Tinbergen, are complementary categories of explanations for animal behaviour. These are also commonly referred to as levels of analysis. [1] It suggests that an integrative understanding of behaviour must include ultimate (evolutionary ...
Carl Gustav Jung [b] was born 26 July 1875 in Kesswil, in the Swiss canton of Thurgau, as the first surviving son of Paul Achilles Jung (1842–1896) and Emilie Preiswerk (1848–1923). [14] His birth was preceded by two stillbirths and that of a son named Paul, born in 1873, who survived only a few days. [15][16]
Behavioral neuroscience, also known as biological psychology, [1] biopsychology, or psychobiology, [2] is part of the broad, interdisciplinary field of neuroscience, with its primary focus being on the biological and neural mechanisms underlying behavior. Cognitive neuroscience is similar to behavioral neuroscience, in that both fields study ...
The Extended Phenotype. The Selfish Gene is a 1976 book on evolution by ethologist Richard Dawkins, in which the author builds upon the principal theory of George C. Williams 's Adaptation and Natural Selection (1966). Dawkins uses the term "selfish gene" as a way of expressing the gene-centred view of evolution (as opposed to the views focused ...
In trait theory, the Big Five personality traits (sometimes known as the five-factor model of personality or OCEAN or CANOE models) are a group of five characteristics used to study personality: [1] openness to experience (inventive/curious vs. consistent/cautious)
