The results of research on emotional intelligence suggest, that it is an internally differentiated construct. Different kinds of emotional intelligence and empirical findings reasoning their separation are discussed in the article. Consecutively contrasted are: ability emotional intelligence (test measured) and trait emotional intelligence (self-report measured); cognitive and 'operative' emotional intelligences; experiential and strategic emotional intelligences; intra- and interpersonal emotional intelligences. Their distinctiveness is testified by their different correlations with other variables; especially with traditionally conceived academic intelligence, personality and temperamental traits, and gender. Presented data lead to the conclusion, that an emotional intelligence's diagnosis should be done by a profile assessment.
