1. Introduction
How do we explain, predict and control human behavior? This question remains a central underlying theme within psychology as a whole. Few specific branches of psychology have attempted to integrate multiple perspectives within their fields of research. Evolutionary psychology appears to be unique in this endeavor, and as the following researchers point out, “Evolutionary psychology is the long-forestalled scientific attempt to assemble out of the disjointed, fragmentary, and mutually contradictory human disciplines a single, logically integrated research framework for the psychological, social, and behavioural sciences—a framework that not only incorporates the evolutionary sciences on a full and equal basis, but that systematically works out all of the revisions in existing belief and research practice that such a synthesis requires” (Tooby & Cosmides, 2005)
A unification of this type is unquestionably an enormous undertaking, but as the following review ventures, it is likely to be a worthwhile contribution to a number of existing disciplines.
2. Goals and Theoretical Framework
In order to reach any type of conclusion with regard to how much of human behaviour can be explained by an evolutionary psychology framework, it is necessary to understand what the goals of such a subject area are: “The goal of evolutionary psychology is to study human behaviour as the product of evolved psychological mechanisms that depend on internal and environmental input for their development, activation, and expression in manifest behaviour.” (Buss, et al., 2010)
Like physiology, anatomy and biology, evolutionary psychology examines human behaviour from a Darwinian perspective. That is, like physical traits, psychological ...

...at seem to contradict Darwinian Theory and either significantly reduce or eliminate an organism’s fitness. However, that is not to say such an explanation within evolutionary psychology cannot exist, it merely means a sufficient one does not currently exist.
Undoubtedly, the claim that all human behaviour can be explained by evolutionary psychology in some way is an ambitious one, but that is perhaps because evolutionary psychology attempts an ambitious goal: to unify not only psychological disciplines, but also the anthropological, sociological and biological. With this in mind, it is easier to see how the foregoing conclusion might be possible, probable even. At the very least, it is undeniable that evolutionary psychology provides a foundation with which to explore and interpret human behaviour even in spite of those subjects with which it says little about.
In this essay, we have been asked to evaluate two psychological perspectives’ in relation to “typical behaviour”. The perspectives I have chosen is the behaviourist and biological approach, to be able analyse these approaches, I have decide to use the case study of the death of the two year old ‘James Bulger’ and with this, the relevant therapy’s used by each perspective.
One of the most revered and utterly enigmatic topics present within humanity is the evolution of humankind itself. Collectively contrasting both the origins of man physically and the very beginning of complex thought processes has been an incredible task, which is currently undetermined. The exact methods of the mind and of human character are both delicate and completely beyond true understanding. The only ways
Not everything lies in nature; nurture also plays a big role in our behavior. Craig Venter, an American biologist quoted in Ridley’s article, says that “the wonderful diversity of ...
The nature vs. nurture debate: the nature side, are those such as biologists, psychologists and others in the natural sciences, argue that behavioral traits can be explained by genetics. Those taking the nurture side are sociologists and others in the social sciences, they argue that human behavior is learned and shaped through social interaction. This argument should be dismissed because you don’t have to look far to see that both genetics and our environment, plays a role in who we are and our behaviors. (Glass). The point is there is a complex relationship between nature and nurture, either one alone is insufficient to explain what makes us human. (Colt). Our heredity gives us a basic potential,...
This chapter discusses The Evolutionary Perspective, Genetic Foundations, reproductive Challenges, and Heredity-Environment Interactions. Natural selection is the process by which those individuals of a species that are best adapted survive and reproduce. Darwin proposed that natural selection fuels evolution. In evolutionary theory, adaptive behavior is behavior that promotes the organism’s survival in a natural habitat. Evolutionary psychology holds that adaptation, reproduction, and “survival of the fittest” are important in shaping behavior. Ideas proposed by evolutionary developmental psychology include the view that an extended childhood period is needed to develop a large brain and learn the complexity of human social communities. According to Baltes, the benefits resulting from evolutionary selection decrease with age mainly because of a decline in reproductive fitness. At the same time, cultural needs increase. Like other theoretical approaches to development, evolutionary psychology has limitations. Bandura rejects “one-sided evolutionism” and argues for a bidirectional lin...
Evolutionary psychology is a specialist field within the spectrum of psychological enquiry, which seeks to examine and understand some of the predominant reasoning behind the concept of why the human species, whilst biologically similar to other species on the planet, is so very distinct in terms of intelligence and mental progression; demonstrated by the multifaceted and complex social structures we have created. Primary to this domain of evolutionary psychological interest is the notion of ‘theory of mind’, which was developed and advocated by Premack and Woodruff (1978), and has been the topic of fierce discussion and analysis since. It has resulted in manifold research studies and commentaries, regarding the topic, from an extensive range of sources within the academic field of psychology. This essay intends to explore the concept of theory of mind, using examples and research studies to fathom its relevance, application and significance within evolutionary psychology as a whole.
The main idea behind this paper was to answer this question: "Who are you?" The article makes you think about how psychologists are able to determine whether a trait being physical or psychological is hereditary, is it taught over your upbringing by your parents, or is that just part of your own personal make up. The article states that “most humans feel that the way that they act and perceive the world is built around an environmental basis rather than being a genetic trait. ”(Are You a Natural)
The biological approach to psychology makes the assumption that all behaviours are associated with changes in the brain function and that psychopathology will be caused by a disorder within the brain, neuroanatomy. Many biological psychologists tend to assume that most behaviours, normal and disordered, involve an inherited component from the biological parents. In theory this suggests that all behaviours can be related to changes in brain activity.
The purpose of this academic piece is to critically discuss The Darwinist implication of the evolutionary psychological conception of human nature. Charles Darwin’s “natural selection” will be the main factor discussed as the theory of evolution was developed by him. Evolutionary psychology is the approach on human nature on the basis that human behavior is derived from biological factors and there are psychologists who claim that human behavior is not something one is born with but rather it is learned. According to Downes, S. M. (2010 fall edition) “Evolutionary psychology is one of the many biologically informed approaches to the study of human behavior”. This goes further to implicate that evolutionary psychology is virtually based on the claims of the human being a machine that can be programmed to do certain things and because it can be programmed it has systems in the body that allow such to happen for instance the nervous system which is the connection of the spinal cord and the brain and assists in voluntary and involuntary motor movements.
Evolutionary theory is developed from Darwin’s argument that “suggests that a process of natural selection leads to the survival of the fittest and the development of traits that enable a species to adept to its environment. “ Many have taken this a step further by saying that our genetic inheritance determines not only our physical traits but also certain personality traits and social behaviors. There is such a controversy over significant behaviors that unfold because many believe that we are already pre-programmed human species. It has also been argued that evolution is reflected in functioning and structure of the nervous system and that is has evolutionary factors that have a significant influence on everyday behavior. With what is being said means that if we follow the evolutionary theory, then it would be said that we are already pre-programmed from before birth to follow certain protocols in life. Whether it is from finding a mate or by getting a job. It also believed that this theory gives use cues from our own system to follow, providing us with certain aspects of life from our ancestors. By believing in this theory we can determine that the importance of heredity when influencing human behavior. Behavioral geneticists and evolutionary psychologists have both agreed that not only do genetic factors provide specific behaviors or traits but it also shows the limitations on the emergence of such traits or behaviors. What this means is that our genetics will determine how tall we will be to how ...
The development of psychology like all other sciences started with great minds debating unknown topics and searching for unknown answers. Early philosophers and psychologists such as Sir Francis Bacon and Charles Darwin took a scientific approach to psychology by introducing the ideas of measurement and biology into the way an indi...
Human behavior is a loosely defined foundation for individuality, generally considered to be influenced and developed by the environment. However, recent molecular studies have exposed genetic factors that suggest a more biological origin for behavior. Gene segments in the genome of humans and other animals have been identified and associated with particular behavioral traits. Is it possible that the presence or absence of even a single gene may predispose one to alcoholism, increased irritability, or enhanced intelligence? Clearly exploration of the nature versus nurture argument with regard to genetic predisposition has social, political, and legal significance.
Many individuals, especially psychologist, question how can they describe a person’s personality using theories in order for society to have an understanding of why people behave the way they do. There have been many debates in regards to this question. Some psychologists state that genetics is one of the main factors why people react a certain way, depending on the circumstance. However, other researchers indicate that the environment plays an enormous role on the individual. Although both of these predictions might be accurate, one will not fully understand unless there is more information linked to their arguments. According to trait theories in the book of Psychology, there are multiple theories that explain different types of possibilities to these behaviors, two of them are called Trait Theory and Social-Cognitive Theory.
Scientists and biologist have argued the Nature versus Nurture debate for decades. This debate is about the degree to which our environment and heredity, affects our behavior and developmental stages. According to this debate, nature can be described as, the behavior of a person is occurring because of their genetic makeup. Since the behavior of a person is due to their genetic makeup, then, it (nature) should also influence a person’s growth and development for the duration of their life. However, the nurture side of the debate says, the cause for an individual’s behavior is because of environmental factors. This would mean that the influence from our family (immediate and extended), friends and other individuals would mold our behavior. Ultimately, no one knows if nature or nurture affects behavior more; or if it is a combination of both nature and nurture dictating an individual’s behavior; or if neither nature nor nurture affects a person’s behavior. This paper will examine the nature versus nurture debate through the topics of violence, intelligence and economics, and sports.
Without evolution, and the constant ever changing environment, the complexity of living organisms would not be as it is. Evolution is defined as a process that results in heritable changes in a population spread over many generations (8).Scientists believe in the theory of evolution. This belief is based on scientific evidence that corroborates the theory of evolution. In Figure 1 the pictures of the skulls depict the sequence of the evolution of Homo-sapiens. As the figure shows, man has evolved from our common ancestor that is shared by homo-sapiens. The change of diet of homo-sapiens over time has thought to contribute to the change in jaw structure and overall skull shape.
