The four branches of emotional intelligence: how to train them one by one

It is 9:45 PM in some kitchen in some city. A woman is washing dishes after the family dinner. On the outside everything is fine —the house in order, the conversation kind, the children tucked in—. But she notices something nobody else sees: the weight on her chest, the shoulders pulled up toward her ears, a kind of quiet electricity in her arms. It is not sadness. Not exactly anger. It is something without a name yet. And if someone asked her “what do you feel?”, she would probably say “I am tired,” because that is what she says when what she actually feels does not fit the vocabulary she has available.

That scene —not knowing what one feels when what one feels is important— is exactly what the first branch of emotional intelligence tries to solve. The four branches of the Salovey-Mayer model are not four versions of the same thing: they are distinct skills, hierarchical, and each one has its own way of being trained. This piece goes into each one separately, shows what distinguishes it from the others, what happens when it is weak, and what kind of practice strengthens it with documented evidence.

1. Why the model is FOUR branches and not one

Before going branch by branch, it is worth clarifying why the model is divided. The intuitive temptation is to imagine emotional intelligence as a single skill —“being good with emotions”— but research showed decades ago that this does not work. People who excel in one dimension fail in another. There are those who understand emotions perfectly and do not regulate them; there are those who regulate with precision without understanding what they are regulating.

The hierarchical division —originally published by Salovey and Mayer in 199010.2190/dugg-p24e-52wk-6cdg— has a deeper reason: complex cognitive capacities get built on more basic ones. Before regulating an emotion, you have to identify it. Before identifying it, you have to pay attention to it. Before using it to think, you have to have recognized it. That hierarchy defines the order of training: bottom-up.

Mayer, Roberts, and Barsade’s comprehensive 2008 review on “human abilities” integrates decades of evidence and keeps this structure10.1146/annurev.psych.59.103006.093646. The hierarchy is not theoretical whim: it is what the tests show —the correlations between branches are moderate, not high—. If it were a single thing, correlations would be almost perfect. They are not.

2. Branch 1: perceiving emotions — the one almost nobody trains

The first branch is the most basic and the most underestimated. It consists of detecting emotional information in oneself, in others, in one’s own body, in images, in tone of voice. It includes both perceptual accuracy (where do I feel this?) and naming capacity (is this frustration or disappointment?).

The opening scene shows the typical failure: someone who feels something but does not identify it. They reduce it to the closest available category —“tiredness”— and move on. The cost is not immediate. It is an accumulated cost: decisions made with degraded emotional information.

Research uses the term “alexithymia” to describe the persistent difficulty of identifying and describing emotions. It is not a universal formal diagnosis, but it captures the phenomenon: between 10 and 15 percent of the general population has pronounced difficulties in this branch, and a much larger percentage has partial difficulties. What is relevant here: the capacity to identify emotions gets trained, and the exercises are surprisingly concrete.

Exercises that work:

• Keep a “sensation diary” for a week: three times a day, write down not what happened but what you felt in the body and which emotional word fits best (even if it does not fit perfectly).
• Expand your emotional vocabulary. The basic cultural list (joy, sadness, anger, fear) is insufficient. Research documents that the English language distinguishes more than 400 emotional states with distinct words; English has more words than Spanish here, but Spanish has more than the basic list. Words like frustration, disappointment, envy, gratitude, shame, guilt, relief, pride —each one carves out a different piece of emotional reality—.
• Brief body scan practice (60 seconds, three times a day): notice zones of tension, heat, pressure, without interpreting yet.

Progress shows up in weeks, not months. People who do these exercises report they start distinguishing nuances they previously blended into one category (“I am bad” breaks down into “I am disappointed, exhausted, and a bit angry at myself”).

*Approximate percentage in the general population with pronounced emotional identification difficulties. The proportion with partial difficulties is much larger.*

3. Branch 2: using emotions — the one that turns information into advantage

The second branch is less intuitive. It is not about regulating, it is not about understanding better —it is about leveraging the emotional state as input for thinking and deciding. The model expresses it this way: emotions organize attention, prioritize memories, modify creativity and motivation, and serve as information about the environment.

A classic example: positive mood states broaden divergent thinking —the capacity to generate new ideas—. That is why brainstorming sessions are sometimes scheduled in pleasant environments, not out of frivolity, but because research shows the emotional state facilitates performance in creative tasks. Another example: a moderate level of anxiety before a presentation useful for the presentation itself —the body activates, attention sharpens, memory works better— than for the casual conversation afterward.

The typical failure of this branch: people who treat emotions as noise to eliminate instead of information to read. They spend the day “enduring” an emotional state instead of asking themselves what it is telling them. This is not the same as branch four (regulating) —which is modulating an emotion that appeared—. Branch two is earlier: leverage the present state as input.

Exercises that work:

• Before a task, briefly register the present emotional state and ask yourself: is this helping or hindering me for this specific task? If hindering, decide whether it is worth modulating (branch four). If helping, use it.
• Practice deliberate emotional transitions. If a task requires curiosity and you arrive rushed, give yourself 90 seconds to generate genuine curiosity —look at the problem as if it were new, read a provoking question— before starting. It is not “acting as if”; it is provoking the state.
• Keep a brief record of which emotional state produced better results in which type of task. After a few weeks, the pattern is clear: each person works better under different emotional conditions.

4. Branch 3: understanding emotions — the one that translates complexity

The third branch is the cognitive part of the model. It consists of understanding how emotions combine, evolve, transform, and mask each other. It includes complex emotional vocabulary —distinguishing between guilt and shame, between envy and resentment, between relief and happiness— and the understanding of progressions (how frustration transforms into anger, how sadness transforms into acceptance, how pride transforms into arrogance).

Here lives one of the most useful and least trained skills: detecting masked emotions. A person can say “I am angry at you” when what they actually feel is fear of disappointing; they can say “I am fine” when they are exhausted; they can say “I do not care” when they are hurt. Understanding emotions is being able to read between the lines what is going on, in yourself and in others.

The Trait Meta-Mood Scale, published by Salovey and colleagues in 1995, specifically measures “emotional clarity” —how well people understand their own emotions10.1037/10182-006. Studies with this scale show something counterintuitive: people with more emotional vocabulary do not necessarily report more positive emotions. They report greater precision —and sometimes that includes admitting negative emotions they previously blended into “I am bad”—.

Exercises that work:

• Study emotional combination patterns. One afternoon, write down five emotions you felt in the last week and try to identify if they were mixed (for example: gratitude mixed with exhaustion over something that cost you a lot). Practice changes the available vocabulary.
• Reading emotionally complex fiction. Novels that explore nuanced inner states work as a gym for branch three: they expose the reader to emotional combinations that rarely appear in everyday conversation.
• Mask-hunting. Three times a day, when an intense emotion appears, ask yourself: what other emotion could be underneath this one? The answer is not always clear, but the habit of asking changes the quality of attention.

*Approximate proportion of adults reporting high emotional clarity in TMMS self-reports. Brief interventions raise this number.*

5. Branch 4: regulating emotions — the one that got misinterpreted

The fourth branch is the most popular and the most distorted. Public conversation translates it as “controlling emotions,” “not feeling,” “being strong.” That is exactly what the evidence does not recommend.

Regulating is not suppressing. Suppressing has documented costs: it increases physiological response, deteriorates memory, reduces relational satisfaction, and paradoxically intensifies the suppressed emotion in the medium term. Experimental research shows that people instructed to “not feel” during an emotional task show greater reactivity to the same stimulus afterward.

Regulating is modulating. It is deciding how much of an emotion I need right now. Sometimes that means lowering the intensity of anger so I can talk without hurting; sometimes it means amplifying sadness to process it instead of covering it up; sometimes it means keeping anxiety at a level that activates but does not paralyze. Each of those uses requires having identified the emotion first (branch one) and having understood what it means (branch three).

The TMMS also measures “emotional repair” —the capacity to modulate emotional state once it has appeared10.1037/10182-006. What interventions show: people with high repair do not suppress more —on the contrary, they often report more emotions—. What they do differently is direct attention and behavior toward change better when they need to.

Exercises that work:

• Cognitive reappraisal: when an intense emotion appears, look for an alternative interpretation that preserves useful emotional information but reduces intensity. A difficult exam can be lived as threat (“I will fail”) or as challenge (“I will learn”). Both are true. Choosing the second modulates anxiety without suppressing it.
• Breathing with a label: during the inhale, name the present emotion; during the exhale, imagine part of the tension releasing. Daily practice for two weeks shows measurable effects on self-reports.
• Move: the body is part of the emotional system. Go for a walk, shake hands and arms, change posture. It is not metaphorical: research shows physical movement modulates emotional state.

|| Branch | Question it answers | Example from an ordinary week | ||---|---|---| || Perceiving | Who is feeling what? | Telling your coworker’s tiredness apart from disinterest | || Using | Which state helps me now? | Activating the right restlessness before starting creative work | || Understanding | Why does it arise, where does it go? | Knowing today’s irritation is fear of a deadline | || Managing | How do I carry it without suppressing it? | Lowering the intensity of anxiety before a difficult call |

6. A real person: the case that shows the four branches at work

A composite scene is worth showing how the four branches look in a life. A 38-year-old woman, professional, with small children. On the outside, everything is fine: stable job, stable relationship, active social life. It is the typical case of someone who “has nothing to complain about” and still carries something —which is exactly what EI as a cognitive capacity tries to address—.

In branch one (perceiving), for years she identified everything she felt as “stress.” It was the only word available for an enormous range of states: exhaustion, frustration, fear of failing, guilt for not being where she wanted, unsaid sadness over a professional choice that no longer fulfilled her. That compression into a single category prevented her from acting with precision.

In branch two (using), she treated emotions as noise. She tried to push past them to “perform.” She did not ask herself what each state told her; she only made sure it did not interrupt her.

In branch three (understanding), the understanding was partial. She knew she was tired, knew she was angry sometimes. But she did not distinguish between guilt (belief of having done something wrong) and shame (belief of being something wrong) —and that is why when she failed at something at work, she did not know whether she was exhausted from working or feeling defective as a professional. The difference matters: each one asks for a different response.

In branch four (regulating), the strategy she had learned was to endure. Clench her teeth, keep going. The evidence shows this strategy works in the short term and deteriorates in the medium term. What changed was not learning new techniques: it was first identifying the emotion she was enduring. Once identified, the techniques that worked before stopped working and others appeared —including, sometimes, feeling the emotion fully on purpose—.

What the case reveals: none of the four interventions alone was enough. She improved when she started treating the four branches as a system —perceiving, using, understanding, regulating in chain, not separately—.

7. Caja de crisis

If your emotions are overflowing right now to a point you cannot manage alone, please do not face this by yourself. EI is a trainable capacity, but when the emotional system is overwhelmed, the next step is talking with someone trained —not training alone—.

8. Clinical details almost nobody mentions

Is there a mandatory order for training the branches?

The hierarchy of the model is logical: perception (branch 1) is a prerequisite for regulation (branch 4). But real practice is not strictly sequential. Documented interventions usually train several branches in parallel, with emphasis on the weakest one. What matters: if you try regulation techniques without having trained perception, the effect is low.

Are the four branches evaluated separately?

Yes. The MSCEIT (Mayer-Salovey-Caruso Emotional Intelligence Test) has sections for each branch with separate scores, in addition to a total score. Result reports usually show the four bars —and it is common to find asymmetric profiles: someone with high perception and low regulation, for example.

Does culture or language affect performance?

Ability tests like MSCEIT are designed to minimize the effect of language, measuring accuracy of emotional perception rather than vocabulary. Even so, the emotional vocabulary available in one's mother tongue affects branch three (understanding). Languages with more nuance for emotions offer more material for that branch.

Can EI be trained in adults?

Yes. Reviews show significant effects in adults, not just children or adolescents. The most documented interventions have between 12 and 30 hours of distributed practice, with gains that persist for months. Branch one (perception) shows the fastest improvements; branch three (understanding) requires more time.

Does high EI protect against emotional exhaustion?

Côté's review on EI in organizations documents protective effects, but nuanced: high EI does not automatically protect against burnout if working conditions are structurally adverse. What it does show: people with high EI manage everyday stress better and recover faster. The difference between structural and individual protection matters.

9. Frequently asked questions

Which of the four branches is most useful to train first?

The first. If you cannot identify what you feel, the techniques of branches two, three, and four operate blind. The good news: the first is the one that shows fastest gains with brief practice —weeks, not months—.

How do I know if I am training the right branch?

Take the eight-question map from the hub’s tool. The questions point to the three TMMS dimensions (attention, clarity, repair) plus the fourth branch. If the map shows one dimension very high and the others low, that is your entry point.

Is high EI visible from the outside?

Sometimes yes. People with high EI are often described by others as “easy to talk to,” “listening,” “not easily rattled.” But the correlation is not perfect —someone with high EI can deliberately choose to appear upset in a negotiation, for example—. EI does not reduce to external kindness.

Are EI and general intelligence (IQ) related?

A little. Correlations between EI and IQ are low, around 0.10-0.20 in most studies. This means they are distinct constructs: you can have high EI and average IQ, or high IQ and low EI. People with both high stand out especially in tasks that combine abstract reasoning and emotional information.

Are self-help books about EI useful?

Some are. What distinguishes serious material: it is based on the ability model, separates EI from personality, and proposes exercises per branch. What usually fails: books that mix EI with “positive energy,” generic “mindfulness,” or “soft skills” —those mix constructs and make it hard to know what you are training—.

10. To close: the open question

You already have the map: four branches, hierarchical, trainable separately, each one with documented exercises. What you no longer have an excuse to believe is that “having emotional intelligence” is a single thing or a fixed trait.

The question this piece hands back to you is operational and worth asking today, without waiting for Monday: which of the four branches concentrates your biggest difficulty today —perceiving, using, understanding, or regulating? Not which you think you should improve —which you know costs you—. The difference between the two matters: the first is aspiration, the second is diagnosis. And training starts with diagnosis, not aspiration.

The remaining pieces of the hub —myth or reality of EI— will show you where the evidence supports the promised benefits and where it does not, so the training effort is applied where it has real return.
