Psychologically speaking personality is all that a person is. It includes everything about the person, his physical, emotional, social, mental, and spiritual makeup. The term personality signifies something deeper than more appearance or outward behavior.
Factors Influencing Personality: The following factors influence the development of the personality of an individual. There are various glands in our body. These glands are cell structures. They are important for the individual’s physical and mental health and development. They secrete different substances which are responsible for this development.
Key Points
Cannon described different types of personality based on glands.
There are two types of glands:
- The Duct Glands
- The Ductless Glands.
The Duct Glands :
- The duct glands secrete their fluids through ducts and channels.
- These glands help in the digestive process.
- If the digestion is proper, then the individual becomes healthy.
The Ductless Glands:
- The ductless or endocrine glands exercise a great influence on the development of the various parts of the body and their activities' emotional stability and temperament.
- The hormones secreted by these glands play a vital role in the making of personality.
- The three important ductless glands are:
| Ductless Glands | Description |
|---|
| Thyroid Glands | - They give alertness and smartness to the individual. - In case the thyroid gland is underactive or destroyed by disease, the individual becomes sluggish, dull, slow, forgetful, and stupid. - His physical, as well as intellectual growth, remain stunted and he becomes ugly. - He may have Goitre trouble also. - If it is overactive, the individual loses emotions. - He becomes restless and irritable. - His physical height tends to be extraordinary. |
| Adrenal Glands | - These are small glands each lying on the surface of each kidney. - They secrete a chemical called Adrenalin. - Normal activity stimulates the muscles and increases strength. - It’s under activity that makes the individual emotionally weak. |
| Pituitary Glands | - These glands are situated at the base of the brain and in the middle of the head. - It is a growth gland. - It is responsible for the uniform growth of the body, i.e. bones, muscles, and limbs. - It promotes general health also. - Its overactivity leads to abnormal growth of the body. - It's under activity that produces dwarf with normal intelligence |
| Gonads | - These are sex glands. - They affect emotional stability and help the general development of the individual. |
