Psychological Testing
Psychological Testing : The measurement of some aspect of human behaviour by procedures consisting of carefully-prescribed content, methods of administration, and interpretation. Test content may be addressed to almost any aspect of intellectual or emotional functioning, including personality traits, attitudes, intelligence or emotional concerns. Such tests are usually administered by qualified clinical, school, or industrial psychologists, according to professional and ethical principles. Interpretation is based on a comparison of the individual's responses with those previously obtained to establish appropriate standards for the test scores. The usefulness of psychological testing depends on its accuracy in predicting behaviour. By providing information about the probability of a person's responses or performance, testing aids in making a variety of decisions. In industrial and organizational settings, psychological testing is used primarily for selection and classification. Selection procedures provide guidelines for accepting or rejecting candidates for jobs. Classification procedures, which are more complex, aim to specify the types of positions for which an individual seems best suited. Intelligence testing is usually supplemented by methods devised expressly to meet the needs of the organization. Another area in which psychological testing is widely used is education. In educational settings, intelligence and achievement tests are administered routinely to assess individual accomplishment and to improve instruction and curriculum planning. In clinics or hospitals also, psychological tests are administered for purposes of diagnosis and treatment planning
