While assessing intelligence, psychologists often found that people with similar intelligence differed widely in acquiring certain knowledge or skills. You may observe in your class that there are certain areas in which some intelligent students do not do well. When you have a problem in mathematics, you may turn to Aman for help, and with similar difficulties in literature you may consult Avinash. You may request Shabnam to sing for your annual function, and may turn to John when facing a problem with your bike.

____________is a preference for a particular activity.

Interest

In order to be successful in a particular field, a person must have both aptitude and interest. Interest is a preference for a particular activity; aptitude is the potentiality to perform that activity. A person may be interested in a particular job or activity, but may not have the aptitude for it. Similarly, a person may have the potentiality for performing a job, but may not be interested in doing that. In both cases, the outcome will not be satisfactory. A student with high mechanical aptitude and strong interest in engineering is more likely to be a successful mechanical engineer.
