The inverse of the Ackermann function appears in some time complexity results. For instance, the disjoint-set data structure takes amortized time per operation proportional to the inverse Ackermann function, [24] and cannot be made faster within the cell-probe model of computational complexity. [25]
Just a note: in the introduction it states, "In mathematics and computer science, the Ackermann function (also known as Ackermann-Peter function) is an important example in the theory of computation.", but doesn't say what the Ackermann function is an important example of.
What is Maslow’s hierarchy of needs? We explain the commonly circulated concept with some examples of how it translates in the real world.
In 1938, the American psychologist Henry Murray developed a system of needs as part of his theory of personality, which he named personology.Murray argued that everyone had a set of universal basic needs, with individual differences among these needs leading to the uniqueness of personality through varying dispositional tendencies for each need; in other words, a specific need is more ...
In 1969, psychologist Clayton Alderfer developed Abraham Maslow's hierarchy of needs by categorizing the hierarchy into his ERG theory (Existence, Relatedness and Growth). The existence category is concerned with the need for providing the basic material existence requirements of humans.
Heinz Werner's orthogenetic principle is a foundation for current theories of developmental psychology [1] and developmental psychopathology. [2] [3] Initially proposed in 1940, [4] it was formulated in 1957 [5] [6] and states that "wherever development occurs it proceeds from a state of relative globality and lack of differentiation to a state of increasing differentiation, articulation, and ...

Social psychology utilizes a wide range of specific theories for various kinds of social and cognitive phenomena. Here is a sampling of some of the more influential theories that can be found in this branch of psychology. Attribution theory – is concerned with the ways in which people explain (or attribute) the behaviour of others. The theory ...
