Intelligence consists of a general factor underpinning all purposeful thinking and behavior together with certain specific factors. It may be better defined as a person’s capacity for processing information. Intelligence is measured in terms of Intelligence Quotient (IQ).
The national average is 100 with 34% of the population having IQs between 85 and 100 and 34% of the population having IQs between 100 and 115. This is known as the 'average’ range. About 16% have IQs above 115 and about 3% above 130.
The Wide Range Intelligence Test is a highly reliable individually administered battery of four sub-tests of cognitive abilities and its use is not restricted to qualified psychologists. It assesses both verbal and non-verbal abilities by means of Verbal and Visual Scales. Each scale consists of two sub-tests each addressing a group of specific abilities of school relevance.
Verbal items are all oral with no reading or writing involved. Verbal IQ measures the functioning of the left hemisphere of the brain which is the hemisphere usually responsible for speech and language whilst the Performance IQ measures the functioning of the right hemisphere which is usually responsible for practical, creative, artistic and visual thinking skills.
