Biological Factors Influencing Personality Development
The process of developing a personality is not a one-way process. His personality is influenced and shaped by a variety of internal and external variables. These elements can be divided into two categories.
The following biological factors are those that have an impact on personality.
The ductless gland: The hormones secreted by the ductless gland are what cause personality development and change. If they secrete normally, the personality will develop normally. Their excessive or insufficient secretion results in a variety of personality defects. Below is a quick summary of them:
- Pancreas: The body receives insulin from the pancreas. The mental faculties are impaired and the personality of the person seems unbalanced when there is an insulin shortage. The individual’s disposition changes to one of irritability.
- Thyroid: Thyroxin is produced by the thyroid. It keeps the body’s metabolic rate constant. Its excessive secretion causes a variety of personality aberrations, such as fast physical development, stress, irritability, and instability. Its insufficient secretion results in dwarfism, intellectual dullness, and physical development retardation.
- Adrenal: The adrenal gland creates the hormones cortin and adrenaline. High blood pressure and a quick pulse are results of an overabundance of adrenaline. Body sluggishness and weakness are caused by its undersecretion. Exaggerated masculinity originates from an overabundance of cortin. A kid as young as 3 or 4 years old may exhibit the physical and sexual development of an adult.
- Gonads: They have a significant impact on a person’s sexual life. They will make the person oversexed if they are hyperactive. The sex drive, however, weakens if they are not active enough.
- Pituitary glands: Master glands is another name for the pituitary glands. It regulates other glands. Its overactivity causes giantess and vigour in the muscles. Its lack of activation causes sluggishness and decreased development.
