Biological Model Of Personality

This division is not based on functionality, but is an aesthetic one. The frontal lobe is the largest of these geographic areas with the Rolandic fissure (Central sulcus) and the Silvian fissure (Lateral sulcus) and the Corpus Callosum creating the boundaries. The frontal lobe is comprised of three functionally specific areas on the surface area of the cerebral cortex: the precentral cortex or primary motor cortex (Brodmann’s area 4), the premotor cortex (Brodmann’s area 6) and the prefrontal

The limbic system (or Paleomammalian brain) is a set of brain structures including the hippocampus, amygdala, anterior thalamic nuclei, and limbic cortex, which support a variety of functions including emotion, behavior, long term memory, and olfaction.[1] The term "limbic" comes from Latin limbus, loosely translating as "border" or "belt".

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

In psychology, there are four major theories of personality: psychodynamic, trait or five-factor model, humanistic, and social-cognitive. The psychodynamic theory primarily focuses on the role of the unconscious mind. The social cognitive theory focuses on the effect of the environment on behavior and is based on theories of learning. Whereas, the humanistic theory emphasizes conscious life experiences and choices. The trait or five-factor model focuses on characteristics themselves and not the roots of personality.

Personality is looked at everyday purposely and accidently. Whether you are judging how your new professor for the semester will be, or if you are studying your best friend for a project, personality is studied abundantly. While there are many ways to define personality, there is not a worldwide definition around. Personality is the unique combination of patterns that influence behavior, thought, motivation, and emotion in a human being (boundless.com). That is one of many ways of defining personality. When examining personality, there are four main approachable theories including: The Psychodynamic Approach, The Trait Approach, The Social-Cognitive Approach, and The Humanistic Approach.

Funder discusses on how personality psychology formulates around numerous basic approaches. One approach Funder talks about is the biological approach, which addresses the mental process on our behavior including anatomy, physiology, genetics, and evolution. This approach analyses our feelings, thoughts, and behaviors through our mind. Another approach that Funder discusses is the trait approach, which is basically the study of human personality; the trait approach concentrates on the way an individual differs in emotion, thought, and behavior and how those differences are measured. These two approaches complement each other because the trait approach focuses on routine patterns of an individual that are behaviors, feelings, and thoughts which those

The brain is the most important organ for regulating human behavior and thought. The brain is very complex and has taken centuries to discover how it functions. The brain is separated into four distinct regions or lobes. These regions are called the frontal lobe, the occipital lobe, the temporal lobe, and the parietal lobe. The frontal lobe is located directly behind the forehead and is the brain region that controls higher level thinking such as memory, planning, and judgment. The frontal lobe also contains motor cortex which allows voluntary movements. Another vital brain region is the occipital lobe. The occipital lobe can be found in the back of the brain. Its job is to process and store visual information. The occipital lobe

Looking at people brains that are at a higher risk can be beneficial to understanding changes before and after episodes. Scientist look at these people brains specifically at the frontal cortex, limbic system, and the amygdala for changes. The frontal cortex is the front part of a person brain used for decision making. Transmissions from the frontal cortex is sent to limbic system which is the site for processing emotions. Signals from the limbic system is sent to the amygdala where the brain experiences emotions. (Schneider)

Scientist has identified the region of the brain that is called the amygdala which is responsible for instinctual reactions including fear and aggressive behavior. (AACAP) The frontal cortex is the area of the brain that controls reasoning and help us think before we act, this develops later. (AACAP)

It is believed that a mutation in the prefrontal cortex predisposes some people to violence. The frontal lobe is what we use to make decisions and, when fully developed, allows us to think carefully about our actions before we take them. An alteration in the prefrontal cortex may make us susceptible to impulsive and rash behaviors. For example, teens tend to be more reckless than adults. The teen frontal lobe is not fully formed, which is the reason for this outcome. Teens also tend to rely on their amygdalas to make decision. The amygdala is the center for powerful emotions, such as anger, jealousy, and guilt. For example, psychopaths have been found to be void of guilt and regret as a result of “the amygdala [being] less activated when they

There are similarities and differences when analyzing the components of biological and humanistic approaches to personality. Maslow’s hierarchy of needs express important aspects of biological factors that approaches personality.

The Amygdala, which help the driver with memory and emotions. This part of the brain comes in when the driver is scared, happy, or angry. When the driver begins to get frustrated and has road rage, it is because of the Amygdala.

To reiterate, the study found that the brain images of those who had been convicted of a murder with aggressive or antisocial disorders showed distinct brain activity compared to those who were labeled as normal. The brain scans revealed a relationship between the orbital frontal cortex, the anterior cingulated cortex, and the amygdala, which has a vast impact on the control of negative and brutal feelings. The orbital frontal cortex has been found to control and limit the motivation of passionate upheavals, the anterior cingulated cortex was found to deal with responses to conflict, and the amygdala is known to control reactions to fear. Similarly, in 1915, neurologist Sigmund Freud claimed that active stimuli in humans push them into action and that these active stimuli are

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.

To begin with, in the article “Personality Dimensions in Nonhuman Animals: A Cross-Species Review”, the basic question is what are the major aspects of nonhuman animal personality? Also another question addressed is if different nonhuman animals respond differently to certain stimuli? The author made use of the Five- Factor Model including Dominance and Activity in order to find the solutions to these questions. Animals are very complex in the sense that they express feelings, motives and emotions in very peculiar ways that we merely are unable to comprehend without expertise and multiple researches. Is it possible for animals to be irritated, depressed, creative or even a combination of all these characteristics. The expression of the personalities in animals while similar to humans, can vary from animal to animal, especially based on whether they are predators or prey.
