The most distant roots of Emotional intelligence can be traced back to Darwin’s early work on the importance of emotional expression for survival and second adaptation. In the 1900s, even though traditional definitions of intelligence emphasized cognitive aspects such as memory and problem-solving, several influential researchers in the intelligence field of study had begun to recognize the importance of the non-cognitive aspects. For instance, as early as 1920, E. L. Thorndike, used the term social intelligence to describe the skill of understanding and managing other people.
Similarly, in 1940 David Wechsler described the influence of non-intellective factors on intelligent behavior, and further argued that our models of intelligence would not be complete until we can adequately describe these factors. In 1983, Howard Gardner's Frames of Mind: The Theory of Multiple Intelligences introduced the idea of Multiple Intelligences which included both Interpersonal intelligence (the capacity to understand the intentions, motivations and desires of other people) and Intrapersonal intelligence (the capacity to understand oneself, to appreciate one's feelings, fears and motivations). In Gardner's view, traditional types of intelligence, such as IQ, fail to fully explain cognitive ability . Thus, even though the names given to the concept varied, there was a common belief that traditional definitions of intelligence are lacking in ability to fully explain performance outcomes.
The first use of the term "Emotional Intelligence" is usually attributed to Wayne Payne's doctoral thesis, A study of emotion: Developing emotional intelligence from 1985 . However, prior to this, the term "emotional intelligence" had appeared in Leuner (1966). Greenspan (1989) also put forward an EI model, followed by Salovey and Mayer (1990), and Goleman(1995).
As a result of the growing acknowledgement of professionals for the importance and relevance of emotions to work outcomes , the research on the topic continued to gain momentum, but it wasn’t until the publication of Daniel Goleman's best seller Emotional Intelligence: Why It Can Matter More Than IQ that the term became widely popularized. Nancy Gibbs' 1995 Time magazine article highlighted Goleman's book and was the first in a string of mainstream media interest in EI . Thereafter, articles on EI began to appear with increasing frequency across a wide range of academic and popular outlets.
Despite this early definition, there has been confusion regarding the exact meaning of this construct. The definitions are so varied, and the field is growing so rapidly, that researchers are constantly amending even their own definitions of the construct. Up to the present day, there are three main models of EI:
Salovey and Mayer's conception of EI strives to define EI within the confines of the standard criteria for a new intelligence. Following their continuing research, their initial definition of EI was revised to: "The ability to perceive emotion, integrate emotion to facilitate thought, understand emotions, and to regulate emotions to promote personal growth."
The ability based model views emotions as useful sources of information that help one to make sense of and navigate the social environment. The model proposes that individuals vary in their ability to process information of an emotional nature and in their ability to relate emotional processing to a wider cognition. This ability is seen to manifest itself in certain adaptive behaviors. The model proposes that EI includes 4 types of abilities:
Different models of EI have led to the development of various instruments for the assessment of the construct. While some of these measures may overlap, most researchers agree that they tap slightly different constructs. The current measure of Mayer and Salovey’s model of EI, the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) is based on a series of emotion-based problem-solving items. Consistent with the model's claim of EI as a type of intelligence, the test is modeled on ability-based IQ tests. By testing a person’s abilities on each of the four branches of emotional intelligence, it generates scores for each of the branches as well as a total score.
Central to the four-branch model is the idea that EI requires attunement to social norms. Therefore, the MSCEIT is scored in a consensus fashion, with higher scores indicating higher overlap between an individual’s answers and those provided by a worldwide sample of respondents. The MSCEIT can also be expert-scored, so that the amount of overlap is calculated between an individual’s answers and those provided by a group of 21 emotion researchers.
Although promoted as an ability test, the MSCEIT is most unlike standard IQ tests in that its items do not have objectively correct responses. Among other problems, the consensus scoring criterion means that it is impossible to create items (questions) that only a minority of respondents can solve, because, by definition, responses are deemed emotionally 'intelligent' only if the majority of the sample has endorsed them. This and other similar problems have led cognitive ability experts to question the definition of EI as a genuine intelligence.
The EI model introduced by Daniel Goleman focuses on EI as a wide array of competencies and skills that drive leadership performance. Goleman's model outlines four main EI constructs:
Goleman includes a set of emotional competencies within each construct of EI. Emotional competencies are not innate talents, but rather learned capabilities that must be worked on and developed to achieve outstanding performance. Goleman posits that individuals are born with a general emotional intelligence that determines their potential for learning emotional competencies. Goleman's model of EI has been criticized in the research literature as mere pop-psychology (Mayer, Roberts, & Barsade, 2008).
Two measurement tools are based on the Goleman model:
1) The Emotional Competency Inventory (ECI) was created in 1999 and the Emotional and Social Competency Inventory (ESCI), which was created in 2007.
2) The Emotional Intelligence Appraisal, created in 2001, which can be taken as a self-report or 360-degree assessment (Bradberry and Greaves, 2005, The Emotional Intelligence Quick Book, Simon & Schuster).
Reuven Bar-On (2006) developed one of the first measures of EI that used the term "Emotion Quotient". He defines emotional intelligence as being concerned with effectively understanding oneself and others, relating well to people, and adapting to and coping with the immediate surroundings to be more successful in dealing with environmental demands. Bar-On posits that EI develops over time and that it can be improved through training, programming, and therapy. Bar-On hypothesizes that those individuals with higher than average E.Q.’s are in general more successful in meeting environmental demands and pressures. He also notes that a deficiency in EI can mean a lack of success and the existence of emotional problems. Problems in coping with one’s environment are thought, by Bar-On, to be especially common among those individuals lacking in the subscales of reality testing, problem solving, stress tolerance, and impulse control. In general, Bar-On considers emotional intelligence and cognitive intelligence to contribute equally to a person’s general intelligence, which then offers an indication of one’s potential to succeed in life.. However, doubts have been expressed about this model in the research literature (in particular about the validity of self-report as an index of emotional intelligence) and in scientific settings (see, e.g., Kluemper, 2008) it is being replaced the trait emotional intelligence (trait EI) model discussed below.
The trait EI model is general and subsumes the Goleman and Bar-On models discussed above. Petrides et al. are major critics of the ability-based model and the MSCEIT arguing that they are based on "psychometrically meaningless" scoring procedures (e.g., Petrides, Furnham, & Mavroveli, 2007).
The conceptualization of EI as a personality trait leads to a construct that lies outside the taxonomy of human cognitive ability. This is an important distinction in as much as it bears directly on the operationalization of the construct and the theories and hypotheses that are formulated about it.
There are many self-report measures of EI, including the EQi, the Swinburne University Emotional Intelligence Test (SUEIT), the Six Seconds Emotional Intelligence Assessment (SEI), the Schutte Self-Report Emotional Intelligence Test (SSEIT), a test by Tett, Fox, and Wang. From the perspective of the trait EI model, none of these assess intelligence, abilities, or skills (as their authors often claim), but rather, they are limited measures of trait emotional intelligence (Petrides, Furnham, & Mavroveli, 2007). The Trait Emotional Intelligence Questionnaire (TEIQue) is an open-access measure that was specifically designed to measure the construct comprehensively and is currently available in 15 languages.
The TEIQue provides an operationalization for Petrides and colleagues' model that conceptualizes EI in terms of personality. The test encompasses 15 subscales organized under four factors: Well-Being, Self-Control, Emotionality, and Sociability. The psychometric properties of the TEIQue were investigated in a recent study on a French-Speaking Population, where it was reported that TEIQue scores were globally normally distributed and reliable.
The researchers also found TEIQue scores were unrelated to nonverbal reasoning (Raven’s matrices), which they interpreted as support for the personality trait view of EI (as opposed to a form of intelligence). As expected, TEIQue scores were positively related to some of the Big Five personality traits (extraversion, agreeableness, openness, conscientiousness) as well as inversely related to others(alexithymia, neuroticism).
Alexithymia from the Greek words λέξις and θυμός (literally "lack of words for emotions") is a term coined by Peter Sifneos in 1973 to describe people who appeared to have deficiencies in understanding, processing, or describing their emotions. Viewed as a spectrum between high and low EI, the alexithymia construct is strongly inversely related to EI, representing its lower range. The individual's level of alexithymia can be measured with self-scored questionnaires such as the Toronto Alexithymia Scale (TAS-20) or the Bermond-Vorst Alexithymia Questionnaire (BVAQ) or by observer rated measures such as the Observer Alexithymia Scale (OAS).
One of the arguments against the theoretical soundness of the concept suggests that the constant changing and broadening of its definition- which has come to encompass many unrelated elements — had rendered it an unintelligible concept:
"What is the common or integrating element in a concept that includes: introspection about emotions, Emotional expression, non-verbal communication with others, empathy, self-regulation, planning, creative thinking and the direction of attention? There is none."
Other critics mention that without some stabilization of the concepts and the measurement instruments, meta-analyses are difficult to implement , and the theory coherence is likely to be adversely impacted by this instability.
Goleman's early work has been criticized for assuming from the beginning that EI is a type of intelligence. Eysenck writes that Goleman's description of EI contains unsubstantiated assumptions about intelligence in general, and that it even runs contrary to what researchers have come to expect when studying types of intelligence:
"Goleman exemplifies more clearly than most the fundamental absurdity of the tendency to class almost any type of behaviour as an 'intelligence'... If these five 'abilities' define 'emotional intelligence', we would expect some evidence that they are highly correlated; Goleman admits that they might be quite uncorrelated, and in any case if we cannot measure them, how do we know they are related? So the whole theory is built on quicksand: there is no sound scientific basis".
Similarly, Locke (2005) claims that the concept of EI in itself is a misinterpretation of the intelligence construct, and he offers an alternative interpretation: it is not another form or type of intelligence, but intelligence--the ability to grasp abstractions--applied to a particular life domain: emotions. He suggests the concept should be re-labeled and referred to as a skill.
Landy (2005) has claimed that the few incremental validity studies conducted on EI have demonstrated that it adds little or nothing to the explanation or prediction of some common outcomes (most notably academic and work success). Landy proposes that the reason some studies have found a small increase in predictive validity is in fact a methodological fallacy — incomplete consideration of alternative explanations:
"EI is compared and contrasted with a measure of abstract intelligence but not with a personality measure, or with a personality measure but not with a measure of academic intelligence." Landy (2005)
In accordance with this suggestion, other researchers have raised concerns with the extent to which self-report EI measures correlate with established personality dimensions. Generally, self-report EI measures and personality measures have been said to converge because they both purport to measure traits, and because they are both measured in the self-report form. Specifically, there appear to be two dimensions of the Big Five that stand out as most related to self-report EI – neuroticism and extraversion. In particular, neuroticism has been said to relate to negative emotionality and anxiety. Intuitively, individuals scoring high on neuroticism are likely to score low on self-report EI measures.
The interpretations of the correlations between self-report EI and personality have been varied and inconsistent. Some researchers have asserted that correlations in the .40 range constitute outright construct redundancy, while others have suggested that self-report EI is a personality trait in itself.
More formally termed socially desirable responding (SDR), faking good is defined as a response pattern in which test-takers systematically represent themselves with an excessive positive bias (Paulhus, 2002). This bias has long been known to contaminate responses on personality inventories (Holtgraves, 2004; McFarland & Ryan, 2000; Peebles & Moore, 1998; Nichols & Greene, 1997; Zerbe & Paulhus, 1987), acting as a mediator of the relationships between self-report measures (Nichols & Greene, 1997; Ganster et al., 1983).
It has been suggested that responding in a desirable way is a response set, which is a situational and temporary response pattern (Pauls & Crost, 2004; Paulhus, 1991). This is contrasted with a response style, which is a more long-term trait-like quality. Considering the contexts some self-report EI inventories are used in (e.g., employment settings), the problems of response sets in high-stakes scenarios become clear (Paulhus & Reid, 2001).
There are a few methods to prevent socially desirable responding on behavior inventories. Some researchers believe it is necessary to warn test-takers not to fake good before taking a personality test (e.g., McFarland, 2003). Some inventories use validity scales in order to determine the likelihood or consistency of the responses across all items.
Landy further reinforces this argument by noting that the data upon which these claims are based are held in ‘proprietary databases', which means they are unavailable to independent researchers for reanalysis, replication, or verification. Thus, the credibility of the findings cannot be substantiated in a scientific manner, unless those datasets are made public and available for independent analysis.
Research of EI and job performance show mixed results: a positive relation has been found in some of the studies, in others there was no relation or an inconsistent one. This led researchers Cote and Miners (2006) to offer a compensatory model between EI and IQ, that posits that the association between EI and job performance becomes more positive as cognitive intelligence decreases. The results of their study show that this kind of compensatory model does exist: employees with low IQ get higher task performance and organizational citizenship behavior directed at the organization, the higher their EI.
