Explain how heredity and the environment influence human development

Heredity- genes application to I Q is still a subjective issue. As suggested by Douglas Wahlsten in a article in Canadian Psychology, an identical environment can elicit different reactions in different individuals, due to variations in their genetic predispositions.

Home Environment The manner in which parents treat their children influences the way in which children interact with one another within and outside of the home. Before describing such efforts in detail, it is useful to define relevant concepts.

He had been convinced that heredity played a dominant part in the causation of both human resemblances and human differences. As the fetus develops the endocrine glands are formed.

Now it is that out activity should be repeated till we get the desired results.

Heredity and Environment: Meaning and Effects

These environmental factors involve several dimensions. Given that biologically related individuals tend to share greater hereditary similarities, it is fair to state that heritability estimates may be thrown off by environmental effects induced by particular genetic predispositions.

8 factors that influence the Growth and Development of an Organism

Heredity, no doubt has its influence on the physiological traits but environment is also the arbiter of our development.

The human individual is the progeny of two parent cells that come together when a male sperm fertilizes a female egg. The notion of nature, therefore, refers to the biologically prescribed tendencies and capabilities individuals possess, which may unfold themselves throughout the course of life.

Given that the degree of genetic determination appears to vary from one dimension to another e. There are as follows: Reportedly, concordance rate for clinical depression is reportedly about 70 percent for identical twins and about 25 percent for fraternal twins.

This is a result of certain genes being left-out of a gene sequence or altered. The biological or psychological characteristics which are transmitted by the parents to their off-springs are known by the name of heredity. Goddard made a study of the Kallikak family. Cambridge University Press, Nature and Nurture Defined Nature refers to heredity: Despite its nomenclature, the nature-nurture controversy in its current state is less dichotomous than commonly believed.

The different treatment had little effect on the basenjis and terriers but a lot on the beagles and shelties. Impoverished Environment Infants and children from low income environments are often underweight and experience stunted growth see ref 2.

Therefore, the genetic similarities between the twins are magnified by virtue of them growing up in the same household. Hormones There are a number of endocrine glands inside the human body.

Despite these similarities, the older child appears socially reserved and quiet, while the younger one, who was born into the same family environment, seems more outgoing.

The problem of nature versus nurture defies satisfactory solution. In a study, Sandra Scarr and Richard Weinberg found that the IQ scores of adopted children showed higher correlations with the IQ scores of their biological parents than with those of their adopted parents.

Heredity and Environment: Meaning and Effects

While the genetic instructions a child inherits from his parents may set out a road map for development, the environment can impact how. Thus, through birth order, it shows how family environment influences one’s personality.

In conclusion, both hereditary and environmental factors can influence a person’s personality. Heredity sets the limitation which environmental differences decide the concluding result. However, genetic factors have a larger effect on personality traits.

Be sure to include the following items in your description: Summarize three theories related to human growth and development and identify at least one influential theorist for each. Identify aspects of the life span perspective.

Explain how heredity and the environment influence human development. Use a minimum of two peer-reviewed sources. Like heredity, environment also has been found to play a very important role in determining the behaviour and personality development of an individual.

The environmental influences are those which act upon the organism at the earlier stages of development, i.e., before and also after birth.

Both heredity and environment contribute to personality traits and that the degree of their individual contributions cannot be specified for any traits. Although a person's environment plays an important part in their personality development, heredity factors play a larger role in deciding disposition of this environment.
