INFLUENCE OF HEREDITY AND ENVIRONMENT ON DEVELOPMENT


On Physiological Appearance
To Study the effect of genetics on physical appearances, Children of many varied races were compared with their parents which determine physical appearances.


On Intelligence

Having experience upon Negroes and White Soldiers in Connection with their intelligence, Yerkes Concluded that due to genetics, there is a different of intelligence between the two scientist have pointed out that the Negroes are always at a disadvantage in tests designed specially for the whites. Intelligence tests developed for one group do not Suit other.

On personality

It is indisputable that genetics determines the difference of Sex and on this basis Some Scientist Contends that genetics determines personality because it is the difference of sex which determines the personality of men and women , People, in general , believe in a fundamental difference in the personality of man and woman due to the difference in sex. Thus, the qualities of patience and emotion are attributed to a woman and she is called the very picture of love and affection.

EFFECT OF ENVIRONMENT

Environment has a very significant effect on man . Its effects Starts from his birth and continues almost till his very death. The status of child , youth and old man in the family and Society  is not the same and as a result of this is difference, a man's personality, role temperaments, way of thinking tendencies, inclinations and characters is affected. In the same way , the status of person his place like school, office, occupations atc. affects his role to a great extent. Environment can be roughly divided into two parts - Controlled and uncontrolled environment and social and geographical environment. In both the social and.geographical environment of man, a part of them is controlled. Both these types of social and geographical environments have a profound effect upon the individual.

EFFECT OF SOCIAL ENVIRONMENT

The various parts of society like the family, school, occupation, social customs and primitive concepts, all affect the individual. In this context one eg. from family life will suffice. In the opinion of the famous psychoanalyst. Sigmund Freud, the personality of a person is fashioned in the first seven years, the rest of the life being an expression of those tendencies. Whether all thinkers agree with freud's opinion or not all have agreed with regard to the effect of the environment on the family upon the character, nature, mental tendencies, habits and behaviors of the individual and there all enough existing causes while justify family's influence upon the individual. This special knowledge can be gained by comparing children brought up in families and those bread
in government institutions. Thus, both genetics and environment are important for the education of child. Both must be improved to realise all-round development of personality while the family provides the heredity, the school may provide such environment and many help in maximum utilisation of genetic traits.

INFLUENCE OF  ENVIRONMENT AND HEREDITY
Heredity -

According to R.S Woodworth - “ Heredity Covers all the factor that are presented in the individual when he begins life not at birth, but at the time of conception about nine months before birth “
Every child comes into the world with certain physical and mental characteristics which he got from his parents and ancestors.
He bron with a body and mind which developed from fertilized ovum, limbs and mind which developed from fertilized ovum, limbs and organs grow from the same.
Thus on account of heredity, the little ones of each animal resembles it for example:
Cat       -  kitten
Dog     -  puppy
Human  - Human
Heredity refers to biological mechanism as a result of which a child receives the traits and characteristics of his ancestors and race through the transmission of particular genes to him by his immediate parents at the time of his conception in the womb of his mother.

Environment

Environment consists of external forces, which influence the growth and development of an individual right from his conception. Before birth the mother’s womb is the place where these force play their part. Nutrition is received by the embryo through the blood stream of the mother. Different environmental force have a desirable impact upon the physical, Social, emotional intellectual, moral and aesthetic development of an individual.


Effect of Environment

Environment has a very significant effect on man. Its effect starts from his birth and continues almost till his very death youth. The status of the child, youth and old man in the family and society is not the same and as a result of this difference a man’s personality, role, temperaments ways of thinking tendencies indications and character is affected. In the same way the status of the person in place like school office, occupation, etc. affects his role to a great extent.


Environment can be roughly divided into  two parts-

Controlled and uncontrolled environment and social and geographical environment. The social and geographical environment of man a part of them is controlled and the other part is not controlled. Both these types of social and geographical environment. The social and geographical environment of man a part of them is controlled and the other part is not controlled. Both these types of social and geographical environment have a profound effect upon the individual.


Relation between Genetics and Environment  


In fact both genetics and environment are important.-Mac Iver and Page have said very correctly “ Every phenomena of life is the product of both. Each determines the character of  life is the product of both. Each determines the character of the individual. Neither can ever be eliminated nor can ever be isolated “


Experiments relating to heredity have proved that is not the sole factor which determines development of personality human beings. And similarly, experiments conducted in the field of environment also indicate that is not the only factor influencing personality.


In Altenberg’s words - “ Each trait request both heredity and environment for its development contribution of Heredity and Environment in Growth and Development.


(1) Physical Growth and development

Height, bodily frames and structure of bodily organs are determined by growth potentials in the genes, the structure of the nervous system also is probably determined genetically.The  limit of sensory motor development are set genetically and these limits vary widely. thus, the great differences in the motor skills and athletic abilities of children, youth and adults are caused largely by heredity. All hereditary influences can be distorted by abnormal on good nutrition are essential. Deficiencies and deprivation inflict huge penalties on the human body.  

(2) Mental Growth and Development
The evidence indicates that children are born with a very wide range of general mental potential and with different potentialities for music, painting the other arts, public speaking and so forth for which limits are set genetically. Good environment is needed for developing abilities levels close to capacity levels.


(3) Mental and Emotional Health and Personality

People seems to be born with physical structures-nervous system, glands and organs on which emotional stability depends and they differ. If children are raised in a healthful home where the blood or foster parents live in love and harmony and are kind and supportive to the children there is a higher greatly in their potential stability as a result that is some people are much more disposed by heredity to mental instability than other probability that the children will have good personality development. In protective environments, fewer of the unstable in the population will become mentally and emotionally ill then in several and insulting environment.


(4) In attitudes , Beliefs and Values

Position in life depends a great deal on capacities, which are set to considerables, which are set to considerable extent by inheritance. Attitudes, beliefs and values develop large from the culture into which one is born and are influenced greatly by ego, or personal involvement.


All these are the contribution heredity and environment in growth and development.


CONCLUSION REGARDING THE RELATIVE IMPORTANCE OF HEREDITY AND ENVIRONMENT


  1. The supposition,that a particular trail in an individual is exclusive the product of his heredity or environment, does not hold any ground. The individual's personality is  the product of both heredity and environmental factors in this connection, Mc Iver and Page have said very correctly that “ Every phenomenon of life is the product of both . Each is as necessary to the result as the other. Neither can ever by eliminated and neither can ever be isolated.”
whatever character or, trait we consider, it require both heredity and development for its development.


(2) The controversial argument regarding the relative importance of heredity is more important than environment or Vice-Versa is same like asking whether seed  or soil is more important than environment or Vice-Versa is same like asking whether seed or soil is more important for the proper development of a plant. The seed and the soil do not work independently, but are, mutually dependent. The seed has the power to grow into a certain kind of plant but how well it grow depends on what soil it gets. The plant cannot grow without either the send or the soil. its need both. we cannot do away with either of them. It is also useless to say that one of them contributes more in the proper, development of the plant.


In the similar way, it is hard to make any statement in favour of either heredity or environment in the process of development of an organism. Both are equally important and indispensable. Also, it is wrong to assume that they are opposed to each other.They are complementary and support each other.


(3) In judging the relation the relationship between heredity and environment, it can now be said that it is absurd to make such statements as heredity or environment the ‘ either’ and ‘or’ relationship between these two terms does not exist.It is always heredity and environment. The personality of an individual is not just the sum total of his heredity and environment.


They further, declare that an individual is the joint product of his heredity and environment just like the area of a rectangle is the joint product of its length and breadth.


In this way, like the bases of a rectangle, heredity provides us the structure on which with the help of favorable environment, desired construction  can be made. The native power and energies of an individual, like the seed lie in the heredity but it is up to environment to extract theses energies and make them able to reach maximum limits.


(4) As a gift from heredity, we get our working capital but it is the environment which gives us the opportunity to invest it the capital as well as the opportunities for its proper development are essential for the proper success in the business. There are instances where individuals starting with a very meager amount have been able to earn in millions.


therefore, it extreme view of hereditarian like Galton Thus far shall thou go no further ‘ is not correct.


However, if we take it for granted, the even ‘ thus far’ we can’t go without the cooperation of environment.”


If the environment cannot .help as in growing beyond the limits determined by heredity, at least give us enormous assistance within those limits. how far can a rubber band be stretched depends upon the nature of the raw material used be stretched depend the nature of the raw material used in it. It can be stretched to the maximum limit but stretching even up to this limit will depend upon the strength of the individual who pulls it and the favorable or unfavorable circumstance at the time of pulling.


Therefore, it is the duty of the teacher and present to see that every child get maximum opportunity for his development . It is true that nothing entirely foreign to one's nature can be acquired. From a tree of cactus, mangoes cannot be growth. But to have fine mangoes out of the seed, which heredity has provided, we must be careful like a wise gardener who provides proper manure and be careful like a wise gardener who provides proper manure and water to his plants and care for their well-beings and safety as he can like him we teacher cannot arrange for the selected seeds and plantation. Heredity factor is out of our control. But environmental influences can be controlled to a great extent with proper environment the native powers which may be dormant are awakened and stimulated to activity. Every child is able to explore his maximum abilities only when he is provided with appropriate opportunities for growth and development.

Concept and Principles of Growth and Development


Concept and Principles of Growth and Development

Generally Growth and Development are used inter changeable and taken as synonyms terms. After conception in the womb of mother change occur. change is the law of nature. A fertilized egg develops as a fetus. Cycle of charge brought about by the process of growth and development takes place in various dimensions physical, mental, social and so on. Both the terms, growth and Development can be used for any change brought about in maturation and learning.
Concept and Principles of Growth and Development
Source
Development of the child is a series of orderly Progression of charge to words Maturity. Orderly means the arrangement of change. Each charge at each stage is dependent upon what preceded it affects what will come later. Development does not take place haphazardly. The term Progressive signifies that changes lead forward and that the direction is towards adaptation which is conducive to survival of the individual.
Growth is generally taken as dimensional augmentation, cellar, multiplication or  qualitative change in size, weight and number.

CONCEPT
The aim of education is to bring about an all-round development in an individual. It is, therefore, imperative that the teachers should be acquainted with the meaning and Characteristics of growth and development. Usually two terms are used interchangeably.

According to L.D. Crow & Crow (1962), growth refers to Structural and physiological changes and development is concerned with growth as well as those changes in behaviors which result from environmental situations.

Growth takes place when a child grows taller, his bones, muscles and other parts of the body increase in size. Maturation is the unfolding of the characteristics with which the individual is endowed. As the child grows, his mind and body mature and the is able to function at a higher level.

Development involves a Series of progressive, orderly and meaningful changes leading to the goals of maturity is attained.

A child or adult may grow very fast, very fat and heavy, but such growth Can hardly be considered development in the sense of advancement to a higher level of maturity.

Actually a person has developed if he is physically healthier or has more sensors motors Skills so that his physical conditions is conducive to greater personal effectiveness. Thus by improving his sensorimotor skills and thereby utilising better the capacities he has received from about two decades of growth, a person can develop even after physical growth stops. Physical growth is quantitative in nature and is usually measured in inches and pounds or their equivalents.

Development has four basic elements:
1. Growth
2. Maturation
3. Experiences
4. Social transmission (learning through language, Schooling or training by parents)
their development and learning.
Development, growth and maturation are terms which are commonly used to convey the same meaning but there is a significant between all these words.


Growth

1. Quantitative Concept  

2. Change in the quantitative aspect come into the domain of growth  

3.The term growth is used in purely physical sense referring to an increase in size, length , height and weight.

4. Growth is one of the parts of developmental process.

5. Growth described the charge which take places in, particular aspects of the body and behaviours of the organism.

6. Growth does not continue through out life.

7. The change produced by growth are the Subject of measurement.

8. They may be quantified  and are observable in nature.

9. Growth may or may not  bring development, A child may grow by becoming fat but
this growth many not bring any functional improvement or development.






Development

1.Quantitative Concept

2.It indicates the charges in the quality or character rather than in quantitative aspects.

3.Development implies overall Change in shake, form or structure resulting in an improved working or function.

4. Development is a wider, and comprehensive term. It refers
to overall changes in the individual .

5. Development describes the change in
the organism as a whole.

6. Development is a continuous process. It goes from womb to tomb. It does not end with the attainment of maturity.

7. Development, as said earlier implies
improvement in functioning and behaviour.

8. They may be qualitative charge which are difficult to measured directly. They are
assessed through Keen observation
in behavioural situations.
9. Development is also possible  without growth as in the cases of some children who do not gain in terms of height weight or size but they do experience functional
improvement or development in physical, social emotional or intellectual aspects.

PRINCIPLES
The change brought about in an individual by the process of growth and development
tend to follow some well defined principles. These are known as principle of growth and development. These principle are being described below :
(a) Principle of continuity
Development follows continuity. It goes from womb to tomb and never ceases. An individual starting his life from a tiny cell development his body, mind and other aspects of his personality through a continuous stream of development in these various dimensions.

(b) Rate of growth and Development is not Uniform
Although development follows continuity yet the rate of growth and development is not steady and uniform at all time. It proceeds more rapidly in the early years of life but shows down in the later year of childhood. Again at the onset of puberty, there is sudden rise in the speed of growth and development but it is not maintained for long. Therefore, at no stage the rate of growth and development show steadiness. It rather take place but fits and starts.

(d) Uniformity of Pattern
Although development does not proceed at a uniform rate and show marked individual difference, yet it follows a definite sequence of pattern and is somewhat  uniform in the off springs of a species. For example, the motor development and language development in all children seem to follows a definite sequence.

(e) Development  Proceeds from General to Specific Response
In all Phase of a child’s development, general activity precedes specific activity. His responses are of a general sort before they become of so specific response as reaching similarly, when a newborn infant cries, the whole of the body is involved.With growth, the crying is limited to the vocal cords, eyes etc. In language development the child learns general word before specific.

(f) Principle of Integration
while it is true that development proceeds from general to specific or from whole to parts, it is also seen that specific response or part movement are combined in the later process of learning or development. It is the integration of whole and its part as well as of the specific and general responses that makes a child develop satisfactory in the various dimension  of his growth and development.

(g) Principle of Inter-relation

The growth and development takes place in various dimensions like physical, mental, social etc. and these are interrelated and interdependent. Growth and development in any one dimension affects the growth and development of the child in other dimensions as well e.g children with above average intelligence are generally found to possess above average physical and social development. The lack of growth is one dimensions. If a child having poor physical development then it also tend to regress in emotional, social and intellectual development.  

(h) Development is Predictable

With the help of the rate of growth and development of a child it is possible for us to predict the range in with his development is going to fall e.g. X-ray of the bones of the wrist of child will tell approximately what his ultimate size will be similarly the knowledge of the present mental ability of a child will help is predicting his ultimate mental development.

(i) Principle of Developmental Direction

Kuppu Swamy has thrown light thrown light on this principle and he points out two specific facts out two specific facts concerning the direction of development. He say that development is “ cephalic-caudal as well as proximodistal”

As per the principle of cephalic-caudal development, the development, the development proceeds in the direction of the longitudinal axis, first the child gain control over his head and arms and then on his leg on that he can stand.

According to the proximodistal tendency of the development, it proceeds from the center to the periphery. In the beginning child exhibits its control over the large fundamental muscles but afterward due to growth and development of smaller muscles he can  exhibit more movements that are refined e.g. Central over the arm and the hand.

(j) Development is Spiral and not Linear

The child does not proceed straightly on the path or development with a constant or steady pace. Actually he makes advancement during a particular period but take rest in the following period to consolidate his development. In advancing further, therefore, he turn back and then moves forward again like a spiral.
Concept and Principles of Growth and Development


(k) Growth and Development is a Joint Product Heredity and Environment

Child at any stage of his growth and development is a joint product of heredity and environment. The forces of heredity and environment directly or indirectly influence his growth and development in any dimension at all times.

(i) Principle of Uneven Tempo of Growth and Development

Growth and development is continuous yet rate of development is not uniform. At earlier stages it is quick and slows down in later year of infancy and at the stage of puberty there is sudden rise in growth and development.

(m) Principal of Unique Development

All children will first sit up crawl and stand before they walk. But the individual children will vary in regard to time or age at which they can perform these activities.

(n) Principle of Interaction of Maturation and Learning

Growth and development happen as a result of both maturation and learning, maturation refers to changes in a developing organism due to the unfolding and ripening of abilities, characteristics, traits and potentialities present at birth, learning denotes the changes in behavior due to training and/or experience, Maturation and learning interact.
