biological factors which may be related to personality are

Human behavior is very influenced by our personality traits, so it can be assumed that genetics also plays a significant role in how we behave throughout our life. Channing Tatum and Scarlett Johannson would likely be mesomorphs. Specifically, study participants with at least one copy of the 7-repeat variant of the dopamine receptor D4 gene had higher scores of self-reported extraversion. Our book refers to temperament as biologically based emotional and behavioral tendencies that are evident in early childhood (Cervone D., & Pervin, 2015 p.488). Reactivity refers to how we respond to new or challenging environmental stimuli; self-regulation refers to our ability to control that response (Rothbart & Derryberry, 1981; Rothbart, Sheese, Rueda, & Posner, 2011). The constitutional perspective, which examines the relationship between the structure of the human body and behavior, seeks to answer this question (Genovese, 2008). On the other hand, Extraversion and Openness can be distilled into a single factor β, or the Plasticity factor. For example, the amygdala and hippocampus of the limbic system mediate emotional intensity and consolidate memory of these experiences. On which areas would you expect you’d score high? Much of the current understanding of personality from a neurobiological perspective places an emphasis on the biochemistry of the behavioral systems of reward, motivation, and punishment. People who score high on this trait are hardworking and dependable. Nature plays an important aspects in forming on one’s personality. They are present under specific circumstances and include preferences and attitudes. Later, the Eysencks added a third dimension: psychoticism versus superego control (Eysenck, Eysenck & Barrett, 1985). Eysenck's three factor model of personality, identical (monozygotic) and fraternal (dizygotic) twins, predisposition is to a large extent hereditarily determined, "Toward a biology of personality and emotion", "Some Implications of the Eysenck-Prell Study of "The Inheritance of Neuroticism:" A Critique", "From Epiphenomenon to Biologically Important Phenomena", "The neuromodulator of exploration: A unifying theory of the role of dopamine in personality", http://rstb.royalsocietypublishing.org/content/365/1560/4001.full.pdf+html, "Testing Predictions From Personality Neuroscience: Brain Structure and the Big Five", "Neural Correlates of Emotional Personality: A Structural and Functional Magnetic Resonance Imaging Study", "White matter integrity and five-factor personality measures in healthy adults", "Affective personality differences in neural processing efficiency confirmed using fMRI", "Why rejection hurts: a common neural alarm system for physical and social pain", "Sociocultural patterning of neural activity during self-reflection", "Interdependent self-construal and neural representations of self and mother", "Neural activity during health messaging predicts reductions in smoking above and beyond self-report", "Personality from a controlled processing perspective: An fMRI study of neuroticism, extraversion, and self-consciousness", "A mechanism for cognitive dynamics: neuronal communication through neuronal coherence", "Rhythms for Cognition: Communication through Coherence", "Amygdala–prefrontal coupling underlies individual differences in emotion regulation", "Neuroticism and extraversion moderate neural responses and effective connectivity during appetitive conditioning", "Network Approaches to Understand Individual Differences in Brain Connectivity: Opportunities for Personality Neuroscience", "Resting-State Functional Brain Connectivity Best Predicts the Personality Dimension of Openness to Experience", "Functional connectome fingerprinting: identifying individuals using patterns of brain connectivity", "Trait paranoia shapes inter-subject synchrony in brain activity during an ambiguous social narrative", "Using connectome-based predictive modeling to predict individual behavior from brain connectivity", "Functional Network Organization of the Human Brain", "The organization of the human cerebral cortex estimated by intrinsic functional connectivity", "Anxious personality and functional efficiency of the insular-opercular network: A graph-analytic approach to resting-state fMRI", "Impulsivity and the Modular Organization of Resting-State Neural Networks", "Functional Connectome of the Five-Factor Model of Personality", https://en.wikipedia.org/w/index.php?title=Biological_basis_of_personality&oldid=994655201, Articles with dead external links from July 2017, Articles with permanently dead external links, Creative Commons Attribution-ShareAlike License, This method measures electrical activity on the surface of the brain through the scalp, and has the high. Researchers analyzed responses from over 1.5 million individuals in the United States and found that there are three distinct regional personality clusters: Cluster 1, which is in the Upper Midwest and Deep South, is dominated by people who fall into the “friendly and conventional” personality; Cluster 2, which includes the West, is dominated by people who are more relaxed, emotionally stable, calm, and creative; and Cluster 3, which includes the Northeast, has more people who are stressed, irritable, and depressed. The limbic system is involved in mediating emotion, behavior, motivation, and long-term memory. Biological Factors of Personality. Eysenck's three-factor model of personality was a causal theory of personality based on activation of reticular formation and limbic system. 1 Biological and Psychological Factors of Personality Growth Locas C. Kindell IDSC 4000 Dr. Cobb 10/20/2018 2 Introduction This research project focuses on the natural processes that influence the development of one’s personality, utilizing research developed and salvaged from the paradigms of Biology and Psychology. This has led to a few biologically based personality theories such as Eysenck's three factor model of personality, Grey's reinforcement sensitivity theory (RST), and Cloninger's model of personality. Optimistic or pessimistic? In the neuroticism/stability dimension, people high on neuroticism tend to be anxious; they tend to have an overactive sympathetic nervous system and, even with low stress, their bodies and emotional state tend to go into a flight-or-fight reaction. Some of those factors are psychological, while others are physical, biological, and hereditary. This method is used to analyze a gene-trait link, by measuring the structure and function of genes in the brain. Recently, psychology professor Colin G. DeYoung has even named the idea as the field of "Personality Neuroscience. Indeed, a growing body of evidence demonstrates that serotonin is associated with Stability and dopamine is associated with Plasticity. Brain defects or injury: Defects in or injury to certain areas of the brain have also been linked to … Based on his observations and interviews of hundreds of people, he proposed three body/personality types, which he called somatotypes. The reticular formation is a region in the brainstem that is involved in mediating arousal and consciousness. [39], Functional connectivity can also be measured at rest, during which individuals are not explicitly engaged in any task. Biological factors which probably are related to personality are chromosomes, levels of mercury or lead in the body, central nervous system arousal level, chromosomes. Based on where you live, do you agree or disagree with the traits associated with yourself and the residents of your area of the country? Other examples include chemical conditions, such as the levels of serotonin in the brain; genetic conditions, including the passing down of personality disorders like schizophrenia; and physiological factors, such as irregularities in the function of the hypothalamic-pituitary-adrenal axis, which helps living organisms adapt to different types of stress. One study has shown that neuroticism is negatively correlated with the structural integrity of white matter tracts that connect various brain regions, such as the prefrontal cortex, parietal cortex, amygdala, and other regions in the subcortex. In an article written by Alison M. Bell and Nadia Aubin-Horth, they describe the advantages very clearly by stating, "For one, it is probable that the genetic basis of personality is polygenic, so it makes sense to simultaneously study many genes. This method involves collecting data for a large number of genes simultaneously which provides many advantages in studying personality. They believed personality is largely governed by biology. In the 1940s, Raymond Cattell developed a 16-item inventory of personality traits and created the Sixteen Personality Factor Questionnaire (16PF) instrument to measure these traits. Over the past two decades, structural magnetic resonance imaging (sMRI) and functional magnetic resonance imaging (fMRI) techniques have been used to study associations between neural activations in the brain and personality traits and other cognitive, social, and emotional processes that characterize personality. skull shape. Hans and Sybil Eysenck believed that our personality traits are influenced by our genetic inheritance. Instead of a trait being present or absent, each dimension is scored over a continuum, from high to low. [51] Another study used a graph theoretical approach to demonstrate that high trait impulsivity was associated with relatively high modularity of resting-state brain networks, such that brain networks exhibited relatively high within-system density of functional connectivity but relatively low between-system density of functional connectivity. link to an assessment based on Cattell’s 16PF questionnaire, link to take the Big Five personality test, http://cnx.org/contents/Sr8Ev5Og@5.52:BtT0nSKq@5/Biological-Approaches, Explain biological approaches to understanding personality, including the findings of the Minnesota Study of Twins Reared Apart, heritability, and temperament, Discuss the early trait theories of Cattell and Eysenck, Describe the Big Five factors and categorize someone who is high and low on each of the five traits, Discuss personality differences of people from collectivist and individualist cultures and compare the cultural-comparative approach, the indigenous approach, and the combined approach to studying personality. How might modeling (environment) influenced your characteristics as well? & Mark Dombeck, Ph.D. There are hundreds of different biological factors influencing the way an individual behaves. Trait theorists believe personality can be understood via the approach that all people have certain traits, or characteristic ways of behaving. Cultural Factors of Personality. Physical factors are one of the major reasons for that. Why might it be important to consider cultural influences on personality? On the other hand, Openness and Agreeableness are positively associated with the structural integrity of these white matter tracts. With these ideas in mind, personality psychologists have become interested in the role of culture in understanding personality. In this model, there are five key traits: 1.) This duality may help explain the two directions that personality studies have taken: on the one hand, the study of ever more specific qualities in people, and, on the other, the search for the organized totality of psychological functions that emphasizes the interplay between organic and psychological events within people and those social and biological events that surround them. They ask whether personality traits are the same across cultures or if there are variations. All of these circuits heavily rely on neurotransmitters and their precursors, but there has been the most research support for dopamine and serotonin pathways: Previous studies show that genes account for at most 50 percent of a given trait. Extroversion is characterized by sociability, assertiveness, excitement-seeking, and emotional expression. According to Hebbian theory, these connections are strengthened and maintained through repeated stimulation between neurons. [1], Since the time of the ancient Greeks, humankind has attempted to explain personality through spiritual beliefs, philosophy, and psychology. Ultimately, it boils down to this feature of neurons that allows the brain to learn from repeated experiences, retain memories, and ultimately maintain personality. He organized these personality traits into three categories: cardinal traits, central traits, and secondary traits. Conciensciousness, 3.) In the field of behavioral genetics, the Minnesota Study of Twins Reared Apart—a well-known study of the genetic basis for personality—conducted research with twins from 1979 to 1999. This section will describe some theories of personality that have a biological basis. In fact, the synchronization of firing rates of neurons across different brain regions helps mediate the integration and processing of information across the brain. The Big Five model of personality is not biologically based; yet some research in the differences in brain structures provided biological support also for this model. [53] Given the role of the FPN in cognitive control, these findings suggest that people high on Conscientiousness may exhibit higher cognitive control. For example, your level of warmth describes how warm, caring, and nice to others you are. [8] This suggests that dopamine and serotonin interact to regulate the conflicting behavioral traits of careless exploration vs. cautious inhibition.[19]. Conscientiousness was associated with increased volume in the lateral prefrontal cortex, a region involved in planning and the voluntary control of behavior. According to Sheldon, the ectomorph personality is anxious, self-conscious, artistic, thoughtful, quiet, and private. Synaptic Self: How Our Brains Become Who We Are: Penguin Books. Family Environment: Every person learns his first lesson from his family. The biological perspective tends to stress the importance of nature. Researchers scientifically investigate the effect of genetic influence through the use of family and twin studies. Essay 5 Biological factors are an important role in your personality. Openness to experience is characterized by imagination, feelings, actions, and ideas. Elucidating the biological underpinnings of criminal behavior and broader, related outcomes such as antisocial behavior can provide insights into relevant etiological mechanisms. Few however, are biologically based. They enjoy intellectual stimulation and feel uncomfortable in social situations. Mesomorphs have large bone structure, well-defined muscles, broad shoulders, narrow waists, and attractive, strong bodies. Instead they fit into distinct geographic clusters. What can whole genome expression data tell us However, saying that a trait is either present or absent does not accurately reflect a person’s uniqueness, because all of our personalities are actually made up of the same traits; we differ only in the degree to which each trait is expressed. [42] For example, a recent line of research has demonstrated that individual differences in functional connectomes, which are characterized by patterns of spontaneous synchronization of neural activations across the entire brain, are predictive of individual differences in personality and sociocognitive functioning, such as openness to experience,[43] fluid intelligence,[44] and trait levels of paranoia. Over the past two decades, structural magnetic resonance imaging (sMRI) and functional magnetic resonance imaging (fMRI) techniques have been used to study associations between neural activations in the brain and personality traits and other cognitive, social, and emotional processes that characterize personality. Consequently, it’s not uncommon to see his theory labeled as pseudoscience, much like Gall’s theory of phrenology (Rafter, 2007; Rosenbaum, 1995). Mental illness arises from a complex interaction of genetic, biological, personality and environmental factors. Secondary traits are those that are not quite as obvious or as consistent as central traits. Page 1 Page 2 Psychologists agree that environmental factors interact with genetic factors to form personality. Do you tend to be sociable or shy? A separate but similar line of research has used diffusion tensor imaging to measure the structural integrity of white matter in the brain. They are curious and enjoy trying new things, but can also be obnoxious and aggressive. There was a stronger correlation among identical twins rather than fraternal twins. Biological factors of personality are very important for the formation of human... 2. Selective migration is the concept that people choose to move to places that are compatible with their personalities and needs. Gray, a student of Eysenck, studied personality traits as individual differences in sensitivity to rewarding and punishing stimuli. For example, one study found that in an emotion regulation task, coupling of neural responses in the amygdala and the prefrontal cortex was significantly associated with more successful regulation of negative emotions. How much of our personality is in-born and biological, and how much is influenced by the environment and culture we are raised in? I have compiled some of the most influential factors when it comes to determinants of personality. [47] These brain networks can also reliably be mapped onto cognitive systems. Before the advent of brain imaging technology, the only method to measure brain activity was electroencephalography (EEG). Cattell (1957) identified 16 factors or dimensions of personality: warmth, reasoning, emotional stability, dominance, liveliness, rule-consciousness, social boldness, sensitivity, vigilance, abstractedness, privateness, apprehension, openness to change, self-reliance, perfectionism, and tension (Table 1). Central traits are those that make up our personalities (such as loyal, kind, agreeable, friendly, sneaky, wild, and grouchy). Sheldon proposed three somatotypes: endomorphs, mesomorphs, and ectomorphs. Actors Adrien Brody and Nicole Kidman would be characterized as ectomorphs. Social Factors of Personality. [34][35] Thus, studies relating neural activation in single regions to personality measures and associated sociocognitive functioning ignore information about how personality and sociocognitive functioning relate to neural activations across multiple regions in the brain. Indeed, examining functional connectivity across the brain may shed more light on the neurobiological basis of personality and sociocognitive functioning. [11][12][14], There are many experimental techniques for measuring the biology of the brain, but there are five main methods used to investigate the biological basis of personality. Oppenness to Experience, 2.) (credit: “Sirswindon”/Wikimedia Commons). People who live in individualist cultures tend to believe that independence, competition, and personal achievement are important. This model of personality is based on the idea that different responses to punishing, rewarding, and novel stimuli the main characteristics of the human mind is caused by an interaction of the three dimensions below: The five factor model (also known as the Big Five) is a widely used personality assessment that describes five core traits that a person possesses: There is large body of research relating the Big Five traits to individual differences in the brain's structure and function, as measured by MRI-based techniques. [45] The use of functional connectomes to predict individual differences is known as “functional connectome fingerprinting” and allows researcher to construct models of personality and sociocognitive functioning based on neural activity across the whole brain rather than within single regions (if using neural activations) or single pairs of regions (if using functional connectivity). Moody or even-tempered? blood type. Autism spectrum disorder, for example, is thought to be caused by chromosomal and genetic abnormalities in some cases, although it is also said to be triggered by environmental factors. Early work using fMRI has studied whether individual differences in personality traits and sociocognitive functioning are associated with individual differences in neural activations in certain brain regions during certain tasks. [40] These resting-state functional connectivities can also be related to personality measures and other sociocognitive functioning. [31] A small collection of fMRI studies have also demonstrated a significant relationship between brain responses to certain tasks and personality survey measures, such as extraversion and neuroticism. It appears that there are both universal and culture-specific aspects that account for variation in people’s personalities. The third approach to cross-cultural studies of personality is the combined approach, which serves as a bridge between Western and indigenous psychology as a way of understanding both universal and cultural variations in personality (Cheung et al., 2011). • Question 4 0.25 out of 0.25 points Biological factors which may be related to personality are Selected Answer: levels of mercury or lead in the body. [11][12] These two meta-traits have been shown to be significantly heritable using behavior genetic analysis,[13] which suggests a neurobiological basis that is unique and specific to these meta-traits. Using MRI-based methods for such studies has become increasingly popular due to the non-invasive nature of MRI and the high resolution of MRI. For example, another measure of personality traits is observation of behavior. [15] The biological data from these methods are commonly correlated with personality traits. Individualist cultures and collectivist cultures place emphasis on different basic values. In reality, most of us tend to lie somewhere midway along the continuum of each factor, rather than at polar ends. [24] In one MRI study,[25] Novelty Seeking correlated with increased grey matter volume in regions of the cingulate cortex, Harm Avoidance correlated with decreased grey matter volume in the orbitofrontal, occipital, and parietal cortex. He developed a personality assessment based on these 16 factors, called the 16PF. Research suggests that many of our personality characteristics have a genetic component. 2. levels of mercury or lead in the body. A high score on this index signifies you are supportive and comforting. Varying polymorphisms and sequence repeats in the gene for dopamine receptor D4 and serotonin transporter gene 5-HTTLPR, have both been found to influence the extraversion trait in adults. Watson and Clark (1984) found that people reporting high levels of neuroticism also tend to report feeling anxious and unhappy. Why or why not. These quadrants are sometimes compared with the four temperaments described by the Greeks: melancholic, choleric, phlegmatic, and sanguine (Figure 3). From a biological perspective, these traits can be traced back to brain structures and neural mechanisms. People tend to be friendly and conventional in the Upper Midwest and Deep South; relaxed, emotionally stable, and creative in the West; and stressed, irritable, and depressed in the Northeast (Rentfrow et al., 2013).
