Evolutionary psychologists view human behavior and psychological traits as a result of evolutionary adaptation in response to reproductive needs – much like the concept of natural selection applied to reproduction‚ or sexual selection. Drawing from this perspective‚ evolutionary psychologists and professionals seek to explain the differences between male and female dating and mating rituals and sexual attitudes and how they have evolved throughout the centuries. For example‚ researchers employ the

Evolution‚ in its most simple sense‚ is described as change over time. I believe it’s important that we understand how evolutionary thinking is relevant to understanding disease as an agent of natural selection because evolutionary thinking taps into two important fields: biology and medicine. It helps us understand the field of biology because evolution helps explain life; specifically differences‚ changes and developments to adapt. On the other hand‚ it helps us understand the field of medicine

The evolutionary approach suggests that our behaviour is determined through natural selection; therefore it is coded into our genes through how we have adapted. It is a biological approach and states nature over nurture. A criticism of this approach is that it is determinist as it suggests that the way we behave is dictated through natural selection‚ for example in gender roles men being strong hunters and wanting a younger female partner. It ignores other suggestions‚ such as how we are brought

The evolutionary perspective on relationships‚ while one of the most thought provoking and interesting‚ is also one of the more criticized perspectives in the field of relationship psychology. The father of evolutionary psychology‚ Charles Darwin‚ foresaw the importance of the evolutionary perspective but could have not predicted all of the faultfinding that would also be attached to this theory. In relation to relationships‚ the evolutionary theory revolves around the ability of men and women to

Evolutionary explanations of aggression Evolutionary psychologists argue that reproductive challenges faced by our ancestors can explain the aggressive behaviour seen in people today. A man can never be certain that he is the father of his wife’s children unless he prevents her having relationships with other men. This can explain why male jealousy is often cited as a cause of domestic violence. In many countries it is seen as acceptable to murder an adulterous wife or her lover e.g. among the Nuer

Throughout the course of life evolution has taken its place on plants and animals. One of the greatest evolutionary changes was the transition of life in water‚ to the transition to life on land. As you can imagine‚ both organisms had challenges moving from this single cellular water environment to a multi-cellular land environment. While the change was difficult‚ this new environment would help organisms flourish in life‚ giving them the ability to reproduce more freely‚ and eat with less competition

A Theory of Human Motivation There are five basic hierarchical needs that each person must satisfy in order to achieve self-fulfillment. These needs begin with physiological‚ which includes the automatic drive to fulfill one’s basic nourishment from food‚ water and air‚ as well as the choices in the selection of these needs. If these basic physiological needs are not met‚ all other needs will be ignored until these are satisfied. Second is the person’s need for safety‚ which yields to short term

When we are attracted to someone‚ our brains release specific chemicals‚ and we subconsciously let the person know we are attracted through body language. Introduction: Your heart starts to race. You fix both your hair and your shirt. Your pupils dilate and your brain releases dopamine and adrenaline. What’s going on with you?

paper‚ I will briefly describe‚ and compare and contrast two theories discussed in the book‚ A First Look at the Communication Theory by Em Griffin: Uncertainty Reduction Theory and the Expectancy Violations Theory. Furthermore‚ I will also include real-life situations that apply to these theories. Expectancy Violations Theory has its roots in Uncertainty Reduction research‚ therefore‚ there will be some similarities between these two theories.
