Operational approach is important to understand the concept of intelligence in clear and definite terms. Scientific terms are not defined in terms of isolation but by stating the observable conditions under which the statement is true or false. Instead of defining the word itself it should be defined under conditions in which it occurs.
A close look at all the above definitions suggest that intelligence is the ability to do a thing. Intelligence is the capacity to acquire knowledge, but it is not knowledge. Intelligence is not thought but the capacity to think. Intelligence is not a skill but is a capacity to acquire skill.
Thus the nature of intelligence may help us to desire a workable definition of intelligence in the following form- ‘Intelligence is the mental ability of an individual which helps him to cope with the new life situations effectively and efficiently.’
Classification of Intelligence according to Thorndike
