Intelligence maybe described as, 'The capacity to learn and utilize appropriately what one has learned. It includes the ability to use one's existing knowledge to foresee problems and to solve them competently. Furthermore it includes the capacity to meet new situations and to adapt readily to a changing environment'. Intelligence can also be explained saying that it is an individual's ability to handle problems which one has to face in his day to day life.
TYPES OF INTELLIGENCE
Two types of intelligence are recognized:
1. Fluid Intelligence
It is relatively culture free type of intelligence that includes pattern recognition, spatial orientation, memory reasoning, and abstraction. This type of intelligence appears to remain stable throughout middle adulthood and then declines.
2. Crystallized Intelligence
It is largely cultural and educationally related intelligence that involves general knowledge, vocabulary and application of knowledge to problem solving and judgment. This type of intelligence continues to increase until mid-sixties and then starts to decline.
