In the psychology of motivation, balance theory is a theory of attitude change, proposed by Fritz Heider. [1] [2] It conceptualizes the cognitive consistency motive as a drive toward psychological balance. The consistency motive is the urge to maintain one's values and beliefs over time.
Evolutionary psychologists consider Charles Darwin's theory of natural selection to be important to an understanding of psychology. [1] Natural selection occurs because individual organisms who are genetically better suited to the current environment leave more descendants, and their genes spread through the population, thus explaining why organisms fit their environments so closely. [1]
The gene-centered view of evolution is a synthesis of the theory of evolution by natural selection, the particulate inheritance theory, and the rejection of transmission of acquired characters. [ 6 ] [ 7 ] It states that those alleles whose phenotypic effects successfully promote their own propagation will be favorably selected relative to ...
Known as the ovulatory shift hypothesis, the theory posits that, during the ovulatory phase of a woman's cycle (approximately days 10–15 of a woman's cycle), [110] a woman who mated with a male with high genetic quality would have been more likely, on average, to produce and bear a healthy offspring than a woman who mated with a male with low ...
Wilhelm T. Preyer, a pioneer of child psychology, was heavily inspired by Darwin's work and approached the mental development of children from an evolutionary perspective. [14] However, evolutionary theory has had a limited impact on developmental psychology as a whole, [5] and some authors argue that even its early influence was minimal. [15]
Evolutionary psychiatry, also known as Darwinian Psychiatry, [1] [2] is a theoretical approach to psychiatry that aims to explain psychiatric disorders in evolutionary terms. [3] [4] As a branch of the field of evolutionary medicine, it is distinct from the medical practice of psychiatry in its emphasis on providing scientific explanations rather than treatments for mental disorder.
In The Social Conquest of Earth (2012), the entomologist E. O. Wilson contends that although the selfish-gene approach was accepted "until 2010 [when] Martin Nowak, Corina Tarnita, and I demonstrated that inclusive fitness theory, often called kin selection theory, is both mathematically and biologically incorrect."
It relies on the idea that there are multi-directional interactions between biological and psychological factors, meaning probabilistic epigenesis is a non-hierarchical model of understanding development. [3] The biological factors, also known as genetic determinants, involve an individual's genetic makeup, and how it influences their behavior. [3]
