“All learning has an emotional basis”, this quote was said by one of the greatest Greek philosophers Plato. The idea that emotions are the basis of learning is the foundation of emotional intelligence. Emotional intelligence is the term coined by psychologists John Mayer and Peter Salovey. It referred to an individual's ability to observe, manage and evaluate their emotions. Many researchers believed that individuals can learn and strengthen their emotional intelligence, while others argued that it is an innate characteristic that people are born with. However, both agreed that emotional intelligence was an essential tool needed to evaluate emotions in oneself and others (Sternberg, 2000, p. 300). Already in the 1940s psychologists began to focus more on cognition, began to research and write more about intelligence and other cognitive aspects, such as problem solving and memory. But it was David Wechsler who began to recognize that there were some non-cognitive aspects that needed to be taken into account. Wechsler himself defined intelligence as "the individual's aggregate or global capacity to act purposefully, to think rationally, and to deal effectively with his environment." Wechsler believed that it was both the nonintellectual and intellectual elements that were important in detecting a person's ability to succeed in life. And these elements included environmental factors and other personal factors of an individual's life (Wechsler, 1940, p. 103). David Wechsler's work on intelligence had influenced many psychologists to continue research in this field. Like Wechsler, Robert Thorndike was also doing intelligence research.
