Evolutionary psychology is an approach in the social and natural sciences that studies the psychological behaviours and adaptations of humans to the changing physical and social environment. It’s basically a combination of evolutionary biology and cognitive psychology. In 1859‚ Charles Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. He believed that all plants and animals had evolved from a few common ancestors by means of natural selection

words: schiz meaning split’ and phren meaning mind’. DSM IV (1994) estimate that the occurrence rate of schizophrenia ranges from 0.2%-2.0% worldwide. There are two main explanations of schizophrenia: the biological explanations and the psychological explanations. In this essay I will critically consider the biological explanations. These include genetics‚ neurochemistry‚ brain structure and evolution. Genetic factors of schizophrenia can be explained using studies on twins and studies on family

Biological explanations for anorexia nervosa Biological explanations for anorexia nervosa include neural explanations and evolutionary explanations. 1st BIOLOGICAL EXPLANATION - Neurotransmitters -Serotonin Disturbances in the levels of the neurotransmitter serotonin appear to be a characteristic of individuals with eating disorders. Kaye 2005 found a reduction in the levels of the serotonin metabolite 5-HIAA in people with eating disorders. This suggests that brain serotonin pathways are underactive

Aggression is a problem that affects all members of society. There is no doubt that aggression pays off for some. Parents who yell and threaten punishment get results. The child who hits the hardest gets the toy. The brother who is willing to be the most vicious in a fight wins. The teacher who gives the hardest test and threatens to flunk the most students usually gets the most study time from students. The spouse who threatens to get the maddest gets their way. The male who acts the most macho

Creationism is often disputed by philosophers and scientists about whether it is an acceptable explanation for the creation of the universe. The majority of scientists claim that there is no room for religion in the creation of the universe and that the creation can be explained only with science. However there are a small group of scientists that believe the God of classical theism had taken part in the creation of universe. One example is Michael Behe. As a professor of biochemistry he believes

Evaluation of Evolutionary Theory of Altruism And The Role Of Genes-A Modern View Background: Evolutionary theory holds that organisms with the strongest genes for survival and reproduction do‚ in fact‚ survive and reproduce most successfully. They thus multiply their genes most widely‚ spreading the advantageous genes through whole populations. Ceaseless repetitions of the process can gradually transform species into totally new ones. Such a world seems to have no place for self-sacrificing

mentions about the Freudian explanation that paranoia originates from the repression of same-sex desire. Sedgwick criticizes this conventional psychoanalysis‚ which inevitably pathologizes homosexuality as paranoia. As borrowing Hocquenghem’s reasoning‚ she argues that paranoia reflects not homosexuality‚ but rather the homophobic perspective on it. Nevertheless‚ Sedgwick condemns‚ many queer theorists duplicate the paranoid structure when they refute the homophobic explanation of paranoia. She infers

Active gene-environment interaction has its foundations in evolutionary theory. Evolutionary theorists had identified that assortative mating allowed individuals with similar traits to gravitate toward one another (Rhule-Louie and McMahon‚ 2007)‚ thus resulting in antisocial behaviour partnerships (Coyne and Wright‚ 2015). Consequently‚ these genes and antisocial environments created by these individuals play a massive role in segregated cross-generational criminal behaviour in families (Baum‚ 2013)
