Essay on Assignment 2 Unit 29

Both of the psychological and biological models explain addiction. In addition, both models take a holistic approach in their arguments. They simply

The biological aspect of addiction takes into account the genetic and inherited components of addiction, as well as the effects of addiction on the body itself. It also includes the neurobiological and neurobehavioral theories and studies, which are becoming the most popular ways in studying addiction. The physical component of addiction primarily relies on the dependence of the substance, the tolerance that the body creates as a result, and the experience of withdrawal symptoms. The psychological

In this booklet you will find an overview of all the different approaches to psychology. This will consist of the key assumptions, examples of the relevant psychologists and examples of their work, as well as an exploration into the advantages and disadvantages that some of these approaches possess.

Psychology, due to its complexity can be approached in a variety of ways. To help us understand the human mind, behaviourist and psychodynamic approaches have helped us understand the alternative outlooks in the science of mind and behaviour. Both approaches can be examined by the means of theoretical assumptions and methodology.

Psychology is not just philosophical speculation and reasoning over the years it has evolved and it is now also recognised as a science, to understand what psychology is all about it is necessary to know it’s origins and the theorist who brought it out of obscurity, Sigmund Freud. He developed the Psychodynamic or Psychoanalytical perspective to enable better understanding of human behaviour these concepts will be discussed further later in this study. After Freud opened the gateway other perspectives and approaches have been developed, now with five main areas of psychology - Cognitive, Behaviourist, Biopsychology and Humanist approaches. For a comparison with the Psychodynamic theory, Behaviourist Theory will be discussed.

Psychology is the scientific “study of the mind” (Gross, 2015) and behavior, which includes the study of humans and animals. There are various approaches in modern psychology. A theoretical approach is a perspective (view) about human behavior, there may be several different theories within an approach, but they all share these common assumptions and principles. (McLeod, 2007). A theory is an attempt by theorists to try to explain behavior. Theories are not facts but can be verified by testing. Theories can then be evaluated which I aim to do through this essay, where I will briefly explain the theoretical approaches in psychology and aim to focus on an analysis for each perspective which consist of the psychodynamic, humanist, cognitive and behavioral approaches where I will analyze the strengths and weaknesses of each approach separately.

Psychology is the scientific “study of the mind” (Gross, 2015) and behaviour, which includes the study of humans and animals. There are various approaches in modern psychology. A theoretical approach is a perspective which is someone’s view about human behaviour, there can be many different theories within an approach, however they all piece together the same assumptions.

This essay will outline and compare both biological and behavioural perspectives on human behaviour. The history, major discoveries and theories will be discussed along with some of the most influential theorists in each of these two areas of psychology. This essay will also compare the two areas strengths and weaknesses in the field of psychology.

To begin with, studies have found that inherited genes are responsible for a considerably large part of the probability that someone will become addicted to any kind of substance or behavior. Addiction is strongly influenced by genetic factors in the later stages of addiction, such as problem use and dependence of an addictive substance. Some genetic factors can make an individual more likely to become addicted to only one specific drug. On the other hand, some genes can make an individual more likely to become addicted in general. Some individuals might be genetically inclined to risk-taking behavior such as receiving large jolts of dopamine through what they consider to be the “excitement” of drug use. These individuals could be subject to keep returning to the illicit and harmful drugs that they find enjoyable despite what they know of the harmful effects. These genetic influences could make them more likely to become addicted to alcohol, cocaine, tobacco, gambling, or any number of substances or activities. Addiction has an inherited component and it

In this essay I am going to explore two of the major approaches to Psychology, Cognitive theories and Behaviourist theories. I will discuss in some detail the two approaches, state how they compare and illustrate the similarities and the differences between them. John Watson, one of the founders of Behaviourism, based his theories on the principles of learning outlined by Pavlov who suggested the theory known as Classical Conditioning; he trained dogs to salivate whenever he rang a bell. Dogs have a natural reflex response to salivate when they see food, Pavlov rang a bell when the dogs were given food and after several repetitions of this action, the dogs began to salivate whenever they heard the bell, even when there was not

Despite the fact that these studies give an overview of how a pleasurable effect can lead to addiction, they do not fully answer the question as to why some people are more prone to this disorder than others. To clarify this uncertainty, factors from all levels of analysis need to be examined. The studies above are fairly reductionist as they only focus on the effect of neurotransmission of dopamine in addictive behaviour and do not consider other aspects that could contribute to addiction. The diathesis-stress model provides a reasonable explanation of addiction as a result of the interaction of biological and environmental factors. Genetics are indeed demonstrated to be a significant factor in addiction. Environmental factors include social identity, social categorization and social learning. Goffman (1986) argues that stigmatized individuals often respond to society's expectations and norms by adjusting the social identity of the group they belong to or of the group they are categorized in: that of an addict. The social learning theory which assumes that 'humans learn behaviour through the environment, but most specifically through observational learning" has also been shown to be involved in addiction. (Niaura, 2000). Akers and Lee (1996) supported the fact that addictive substance abuse can be a consequence of social learning in their longitudinal study with aim to test the social learning model of

The purpose of this essay is to outline and evaluate at least three psychological perspectives of human behaviour. The three approaches that will be summarised are humanistic, social learning theory and the Biological approach. They will also be criticised and compared to one another. A brief description on psychology will occur, and there will also be a short summarisation on some key early influences of psychology, from its origins in philosophy.

Whereas the psychodynamic model began looking at the clinical work of physicians the behavioural model began in laboratories experimenting on behavioural conditioning, using stimuli and rewards, observing how their manipulations affected the responses of the individual they were studying. This model unlike the psychodynamic model can be tested and it is because of this that this model holds more weighting than the psychodynamic model when trying to understand ‘abnormal’ behaviour. However this model is not without its weaknesses as there is no evidence that individuals that display ‘abnormal’ behaviour are victims of improper conditioning. Behaviourists would argue that ‘abnormal’ functioning is learnt behaviour, and not environmental or genetic, the
