Abstract
The study of intelligence within the scientific community is not a new development. Symbolically, the study of intelligence is related to research in the cognitive domain. The cognitive domain refers to the knowing domain. That is why when knowledge is imparted, the objective is to ensure that the recipient is familiar with the cognitive aspects of the knowledge gained. In this area of intelligence, the cognitive field refers to the mode of thinking that controls memory and directs problem solving (quantitative and qualitative skills) aspects of the brain. However, in the last sixty years many psychologists have researched the non-cognitive intelligence and this area is presently gaining momentum. The non-cognitive intelligence domain involves emotional understanding, empathy, and compassion. This non-cognitive field of intelligence is commonly known as emotional intelligence. In 1937 Robert Thorndike researched "social intelligence", and highlighted that social intelligence is the precursor to modern research in emotional intelligence. Then in 1940 the distinguished psychologist, David Wechsler, conducted an intense study that stated "non-intellective abilities" is a crucial element as it helps predict the success of individuals in life. In the early 1950s the Office of Strategic Services developed an assessment system that evaluated non-cognitive abilities. This assessment tool was first used in business by AT&T in 1956. In 1959, the psychologist John Hemphill stated that emotional balance is an important aspect in the deliverance of effective leadership. Subsequently, in the early 1990s renowned psychologists such as David R. Caruso, Peter Salovey, John Mayer, and Daniel Goleman brought emotional intelligence to the forefront of management and intellectual theory. Today emotional intelligence is of great importance to numerous businesses and social applications.
