Correlation Between Intelligence And Children

Intelligence has been defined in many different ways such as in terms of one's capacity for logic, abstract thought, understanding, self-awareness, communication, learning, memory, planning, creativity and problem solving. It can also be more generally described as the ability to perceive and retain information and apply it to itself or other instances of information creating referable understanding models of any size, density, or complexity. This ability significantly increases the adaptive capacity of people and animals. Unlike the separate cognitive functions, advanced intelligence is the ability to solve a wide range of different tasks, including tasks which the subject faces for the first time in life. Education, cultural and social environment …show more content…
Data of at least 25 research files clearly indicate that the coefficient of correlation between the level of intelligence and brain volume is 0.33 (McDaniel, 2005). Gray matter volume is stronger correlated with the level of intelligence in comparison with white matter volume (Colom, Haier, Head, Alvarez-Linera, Quiroga, Shih, Jung, 2009). It is important that correlations between volume of the brain and intelligence in populations of children are lower in comparison with populations of adults. Lower correlation in the population of children explains by the incomplete maturation of the cerebral cortex that occurring in different brain structures at different …show more content…
This coefficient of correlation is comparable with the coefficient of correlation between age and performance of academic skills (counting, reading, comprehension) (0.80-0.90).
There is interesting evidence of declining ability to remember a large amount of words in adolescent girls over the age of 13 years compared to girls 11-12 years old with the maximum volume of lexical memory (Waber, 2007). Thus, despite the general tendency to increase the effectiveness of cognitive activity, some cognitive functions may undergo a negative dynamics.
So in modern society the cognitive development of healthy children is more rapid and reaches high performance in comparison with previous generations. These neuropsychological and neuroimaging studies are connected with the concept of critical periods in cognitive development. During these periods the formation of certain cognitive functions occurs especially intensive, and achievable level determines further possibilities of the
