Test ), to assess the ability of children's performance at school. They developed a table used to compare the mental age of a child to the actual age to produce the concept of I.Q. The conclusion was that a particular intelligent person often seem quick and capable of juggling many ideas at once.Not to be outdone, Wechler developed intelligence scales for both adults and children (WAIS & WISC). The scales are in two parts VERBAL AND PERFORMANCE, giving a clear picture of the person's IQ; by identifying their strength and weaknesses in specific areas .The information can be used in planning individualized instruction programs.To help us understand the nature side of intelligence versus the nurture side Psychologists Bouchard McGue (1981), and Harrell et al(1955) provided us with correlations and comparisons . In the case of Bouchard and McGue the correlations thus provided were:Identical twins reared apart.72Identical twins reared together.86 compared toNon-identical twins reared together .60Siblings reared apart.47Then child and natural parent.50 while.Then child and adopted parent.19These results appear to strongly support the nature issue.Numerous studies show or emphasizes the influences that environmental factors have on Intelligence. Harrell et al (1955) compared two groups of enormously deprived, pregnant women One group was given dietary supplement, the other none, the ages of 3 and 4yrs, the supplement mother's children, scored higher than the other children.Goldfaith (1944) and Skeels(1966) in their research concluded that children raised in deprived orphanages often show serious intellectual deficits, but make marked progress, if removed to a more stimulating environment.Even though Intelligence can be determined through environment, researchers are finding out that people change as they grow older, and their experiences in certain areas can be optional.These options in behaviour differ in various countries and in diffe...
