Development of human intelligence essay

Heritability and malleability of intelligence Intelligence has historically been conceptualized as a more or less fixed trait. Sir Francis Galton, detail of an oil painting by G. Third, the significance of a given test score can be different for different people. Thus, the part of the brain that is able to process abstract thought is used to help us navigate and cope with our "foreign" environments.

I believe the independent domain model is more realistic since there have been numerous studies showing that the psychological mechanisms of the brain are unlinked.

Intelligence: Essay on Intelligence (940 Words)

Development of intelligence There have been a number of approaches to the study of the development of intelligence. Third, the significance of a given test score can be different for different people.

Moreover, the psychologist Robert Plomin and others have found that evidence of the heritability of intelligence increases with age; this suggests that, as a person grows older, genetic factors become a more important determinant of intelligence, while environmental factors become less important.

The concept of mental age fell into disfavour, however, for two apparent reasons. It is thought that either natural selection or sexual selection is what drives this change in gene expression. The child who has reached the formal-operational stage, however, will adopt a strategy of systematically varying alternations of digits, starting perhaps with the last digit and working toward the first.

Therefore, there are a number of definitions. As a second part of his theory, Piaget postulated four major periods in individual intellectual development.

For example, in America with the large abundance of food that we have, the inborn predisposition to foods high in sugar and fat is no longer an adaptive advantage, but might actually shorten the life span of an individual by increasing the risk of obesity and heart disease.

Over time, theorists chose particular tasks for analyzing human intelligence, some of which have been explicitly discussed here—e.

Measuring intelligence Almost all of the theories discussed above employ complex tasks for gauging intelligence in both children and adults. Most important, it should be noted that these differences are based on IQ alone and not on intelligence as it is more broadly defined.

Psychometric theorists, for instance, have sought to understand how intelligence develops in terms of changes in intelligence factors and in various abilities in childhood.

This means that many of the psychological mechanisms that evolved over the backdrop of an ever constant savannah environment are now useless given the modern environment. In her research on the cultural contexts of intelligence, Greenfieldwhile studying indigenous Mayan people, found that the Mayan conception of intelligence is much more collective than the conception of intelligence in European or North American cultures.

During this period, a child learns how to modify reflexes to make them more adaptive, to coordinate actions, to retrieve hidden objects, and, eventually, to begin representing information mentally. The formal-operational child develops thinking skills in all logical combinations and learns to think with abstract concepts.

The fact that most people now posses this trait of increased sensitivity to GABA suggests that it is such an important trait that it has evolved and remained a favorable trait over several millennia. The Molecular Biology of Intelligence There have been several examples where one specific gene has been linked to loss of function or disease.

One such study was done to compare the correlation between IQ, which measures g, and the success of individuals in finding a mate, which was measured in terms of marriage. An example of a verbal subtest would be vocabulary, whereas an example of a performance subtest would be picture arrangement, the latter requiring an examinee to arrange a set of pictures into a sequence so that they tell a comprehensible story.

Therefore, the psychological mechanism of general intelligence is not divided into smaller groups based on specific cognitive action; rather that it is a category that encompasses all cognitive ability.

If an individual was not able to control primal urges and behave in accordance with the social norms of the times, whether prehistoric or modern, this individual would be exiled from the group. As a second part of his theory, Piaget postulated four major periods in individual intellectual development.

An earlier tradition, and one that still shows some influence upon the field, is that of the English scientist Sir Francis Galton. This systematic way of thinking is not normally possible for those in the concrete-operational period.

This paper will highlight the development of human intelligence (HUMINT) and the importance of it in intelligence operations. HUMINT can provide information in areas that technical intelligence cannot and also drive the collection requirements of these disciplines when additional evidence is needed.

Human Intelligence Essay Although it seems easily Development of gender identity is a step towards assuming a gender role, Evolution of human intelligence The evolution of human intelligence refers to a set of theories that attempt to explain how human intelligence has evolved.

Research on human intelligence has become intense in trying to answer the several questions raised on basic structure and mechanisms of intelligence following the discoveries made in relation to genetics of intelligence and it’s functioning in the most recent stages of human development.

Intelligence plays a very important role in a human development. Intelligence is unique ability which humans need in order to function in the society. According to Jean Piaget () intelligence invents a product of the relation between a human and external environment.

HSV Human Development-Early Memory Development Dianne Wright Post University Introduction Many human development specialists have examined memory loss of adults later in life.

During the past fifty years, there have been many studies in children’s cognitive development and earlier childhood memory loss.
