Biological Perspective : The Biological Theory

Hans Eysenck, a psychologist well known in the field of personality based his trait theory on biological explanations; whereby he believed genetic and biological factors were significant elements of personality (Eysenck 1990). Eysenck also held the view that an individual’s personality traits, or what he referred to as ‘temperament’ was an exact result of one’s genetic make-up (Chamorro-Premuzic & Furnham, 2005). Eysenck encompassed the idea that there was a need to highlight the significant dimensions of personality, create a way in which they could be measured and then link them with experimental procedures. Subsequently, Eysenck developed a model of personality based on a theoretical and statistical approach to the classification of traits. This is

Burger (2008), says that there are many theories of personality and psychologists try to explain it with their own approaches. Discussed here will be the psychoanalytic approach, the trait approach, the biological approach the humanistic approach, the behavioural/social learning approach and the cognitive approach. They were devised to search for specific patterns in behaviour and ways of thinking about these

Every single individual has a personality; it is the very quintessence of human existence. Personality drives our interactions with others, our desires – conscious and unconscious, our perceived needs, and to a certain extent, even our actions. Psychodynamic approaches to personality are focused on the belief that we have virtually no control over our own personality, that it is primarily controlled by unconscious powers. Social cognitive approaches to personality centers around the belief that we still have

Biological theories suggest genetics have a big part to play in personality. Some have suggested that people with high cortical arousal are introverts who avoid stimulation. While individuals with low cortical arousal are extroverts who look for stimulating

Personality and how we behave have been of much interest to psychologists for a long time now and because of this there have been many theories and theorists that have been developed. Personality is defined as consistent behavior patterns and intrapersonal processes originating within and individual (Fritzley, 2012, p. 10). There are six main approaches to personality psychology they include: biological approach, humanistic approach, behaviorist approach, trait approach, psychoanalytic approach and cognitive approach. Each approach shines a little light onto why we behave the way we do and how our personalities are formed, the approaches contain many different theories from

First we will look into the biological aspect of human behavior. Biological pertains to one’s body chemistry and from a psychological standpoint the chemistry of the brain. No two people have exactly the

Therefore the trait approach, the measurements of our accustomed traits are complementary to the biological approach because our patterns are personality traits come from our genetics, physiology, evolution, and anatomy vs. competing with one another because both are needed to understand the psychological traid because it addresses the three main parts how we feel, act, and think.

The trend of neurobiology and physiology predicting and causing behavioris not a new fact. So many illnesses and diseases are now attributed to biological mechanisms. A recent article in Newsweek comments on how those in the field of psychology and neuroscience are beginning to stress the fact that certain brain mechanisms account for mental illnesses and particular behaviors. Doctors seem to blame their patients peculiarities on a biologically based mental illness, rather then seeing them as individual responses to lifes circumstances (Begley 1998). It then becomes more common to prescribe drugs to alleviate the symptoms rather than understanding the behavior. Two recent developments have

Biological Theories are vastly growing with fascinating research. The main stump is concretely linking it to criminal behavior, because some theories are more relatable than others. Theories involving temperament and hormones give real life biological explanations, while others like extrovert and introvert behaviors, and neuroticism explain a weaker link to crime. However, all theories are valuable in exploring the root of crime.

The main assumption of the biological approach is behaviour and experiences can be explained by biological changes in the body. This approach focusses on the investigation of the brain, nervous system and other biological factors such as hormones; whereas the main assumption of the cognitive approach is that information received from our senses is processed by the brain and that this processing influences how we behave or at least justifies how we behave the way we do. Cognitive processes are examples of hypothetical constructs – researchers cannot directly observe processes such as thinking but we can infer what a person is thinking based on how they act (behavioural patterns). Some key researchers in the biological approach are Maguire et. Al (2000) - Navigation-related structural changes in the hippocampi of taxi drivers, and Sperry (1968) - Hemisphere disconnection and unity in consciousness. Some key researchers in the cognitive approach are Loftus and Palmer (1974) - eyewitness testimony and Baron-Cohen (1997) – Autism.

BTEC Level 3 Applied Science Unit 34: criminal psychology Explain how psychological perspectives have been used to explain criminal behaviour Biological theory Biological theory advances the evolution and cognition with an emphasis on the conceptual integration afforded by evolution. Biological theories: Biological perspective is relevant to the study of the psychology in three ways: comparative method: Many species can be studied and be compared. This can help them in search of human behaviour. physiology: The nervous system and hormones work, how the brain functions and how the structure can affect criminal behaviour.

Biological, psychological, and sociocultural viewpoints have been developed in an attempt to explain schizophrenia. All three viewpoints point out various factors that may contribute to the development of the disorder.

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.

Over the years, psychologists have been concerned with determining the relative amount contributed by genetics or environmental factors to different behavior. They also often ask the

This essay will give a description of Personality before critically analysing the biological basis of personality approach. The biological basis approach tries to account for the mechanisms between genes and personality by looking at various different brain structures whilst the biochemical approach looks at the impact of hormones and neurotransmitters. The majority of our understanding of personality from a biological perspective focuses on the three main behavioural systems; the reward system, the motivation system and the punishment system. Within this essay I will be discussing the three main theories that have come from these ideas, Eyenck’s three-factor model, Gray’s reinforcement sensitivity theory (RST) and Cloningers model of personality.
