Personality is the unique pattern of thoughts, feelings, and behaviors that make up an individual's character. It is a complex and multifaceted construct that is shaped by both genetic and environmental influences. While many people believe that personality is largely determined by one's upbringing and life experiences, research has shown that biological factors also play a significant role in shaping an individual's personality.
One of the most well-known biological influences on personality is genetics. Studies have consistently shown that there is a significant genetic component to personality, with estimates ranging from 25-50% of the variance in personality traits being attributed to genetics. This means that certain personality traits are more likely to be inherited from our parents or other family members. For example, research has found that traits such as extraversion, agreeableness, and conscientiousness have a moderate to high heritability.
Another important biological factor that influences personality is the neurotransmitter systems in the brain. These neurotransmitters, such as serotonin and dopamine, are chemicals that transmit messages between nerve cells and play a key role in regulating mood, motivation, and behavior. Dysfunctions in these neurotransmitter systems have been linked to various personality traits and disorders. For example, low levels of serotonin have been associated with aggression and impulsive behavior, while high levels of dopamine have been linked to novelty-seeking and risk-taking behavior.
Another biological factor that can influence personality is the hormonal system. Hormones such as testosterone, estrogen, and cortisol are known to affect behavior and emotion. For example, high levels of testosterone have been associated with assertiveness and aggression, while high levels of estrogen have been linked to sensitivity and emotional reactivity. Similarly, cortisol, a stress hormone, has been linked to negative emotions and a lack of social support.
In addition to genetics, neurotransmitter systems, and hormones, other biological factors that may influence personality include brain structure and function, as well as epigenetic changes. Epigenetic changes refer to changes in gene expression that are not caused by changes in the DNA sequence itself, but rather by external factors such as stress or diet. These changes can have long-term effects on an individual's behavior and personality.
In conclusion, biological factors play a significant role in shaping an individual's personality. From genetics and neurotransmitter systems to hormones and epigenetic changes, these factors interact with environmental influences to create the unique personality of each individual. Understanding these biological influences can help us better understand the complexity of personality and how it develops.

Behavior is changed by helping the person understand and think about the world differently. Nonetheless, regardless of numbers of study provided, genetics cannot be proved to be the only reason that causes schizophrenia or similar symptoms. These are abbreviated to A, C, G, and T. If you decide that it's due to his upbringing, you're siding with the nurture side of the debate. Neurological studies have also provided corroborating evidence for the role of genetics with regard to impulsive aggression. The occipital lobe takes in visual information, processing it to send to further forward lobes. Cesare Lombroso's Three Stages Of Crime 1188 Words 5 Pages Dizygotic twins are genetically similar as siblings.

Abrahamson, Baker and Caspi 2002 concluded that genetic factors influence social attitudes much earlier than they previously claimed. Endomorphs enjoy affection and detest disapproval. Answer and Explanation: Biology plays a great role in psychology encompasses domains such as physiology, evolution, and chemical processes—all of which have demonstrated their capacity to influence behavior and human development. Whether one scores high or low for that specific personality, it is not a 100 percent accurate portrayal of that person.
Conversely, introverts, through their high excitatory potential, are already reasonably alert and thus less prone to switching their attention to other sources of stimuli; in other words, introverts are less easily distracted than extroverts.

However, since most of the adoption studies only used samples of the biological mother but not the biological father, a lot of factors and causes are being missed out such as which of the biological parents are more likely to pass the disorder to the children. Biological processes influence psychological processes by providing the actual components that drive mental processes and behaviors. Wear and tear theory asserts that cells and tissues simply wear out.
