Nature of emotions
The word emotion comes from Latin emovere, "to stir up". An emotion is a complex pattern of arousal, thought and behaviour in response to a situation we see as important.
Three parts
- Physiological: changes in the body controlled by the autonomic nervous system: heart rate, breathing, sweating, blood pressure.
- Cognitive: how we appraise (judge) the event. The same exam result can bring joy or sadness depending on what we expected.
- Behavioural: facial expression, voice, posture and actions.
Features
- A few basic emotions are found everywhere: joy, sadness, fear, anger, surprise, disgust (Robert Plutchik listed eight, adding trust and anticipation).
- Emotions vary in intensity (annoyance → anger → rage) and can mix (joy + fear = thrill).
- Emotions are short-lived; a longer, milder state is a mood. Emotions also have motivational power: fear makes us escape, joy makes us repeat.
Expression of emotions and culture
Emotions are expressed through verbal (words, tone, loudness, speed of speech) and non-verbal channels (face, eye contact, gestures, posture, touch, distance).
Facial expression
Studies of many societies show that faces for basic emotions (happy, sad, angry, afraid, surprised, disgusted) are recognised in most cultures. This suggests a shared biological base.
Role of culture
- Display rules: each culture teaches when, where and how strongly an emotion may be shown (hiding disappointment when receiving a gift, not laughing loudly at a funeral).
- Gestures and body language differ: a head movement or hand sign can mean "yes" in one place and something else elsewhere.
- Cultures also differ in which emotions they value; many Indian traditions describe emotions through rasas in art and drama, and value calm and self-control.
Managing negative emotions
Negative emotions (fear, anger, sadness) are normal and useful signals, but when too strong or too long they harm health, relationships and study. Healthy ways to manage them:
- Self-awareness: notice and name the feeling ("I am anxious").
- Appraise again (reappraisal): look at the event in a new, balanced way.
- Relax: slow breathing, muscle relaxation, meditation or yoga.
- Exercise and good sleep use up extra arousal.
- Social support: talk to friends, family or a counsellor.
- Problem-focused action: act on the cause when possible; avoid unhealthy escapes like shouting or overeating.
Building positive emotions
Positive emotions (joy, hope, contentment, love) do not only feel good; they widen our thinking and build strength for hard times. Ways to build them:
- Gratitude: note good things each day.
- Hope and optimism: set small goals and see paths to them.
- Kindness and helping others.
- Close relationships and time with supportive people.
- Flow: deep involvement in an activity you love (music, sport, drawing).
- Finding meaning, having faith or values, and taking care of the body.
Key formulas and definitions
- Emotion = physiological arousal + cognitive appraisal + behavioural expression
- Basic emotions: joy, sadness, fear, anger, surprise, disgust (+ trust, anticipation in Plutchik)
- Intensity: annoyance → anger → rage; mixing: joy + fear = thrill
- Expression: verbal (words, tone) + non-verbal (face, gestures, posture)
- Display rules = culture's rules on when and how to show emotions
- Manage negative: notice → rethink → relax → exercise → talk/support
- Build positive: gratitude, hope, kindness, relationships, flow
Worked examples
1. Kiran sees a snake on the path: heart pounds, she thinks "it may be poisonous", and jumps back. Label the three parts.
Physiological: pounding heart. Cognitive: "it may be poisonous" (appraisal). Behavioural: jumping back.
2. Two students both get 75%. One is happy, the other sad. What explains the difference?
Cognitive appraisal. The first expected 60% and sees it as a gain; the second expected 90% and sees a loss. The event is the same; the judgement differs.
3. A child receives a gift she dislikes but smiles and says thank you. Which idea is shown?
Display rules: her culture teaches her to hide disappointment and show politeness when receiving a gift.
4. Varun is furious after losing a match. Suggest three ways to manage it.
(1) Notice and name it: "I am angry because I lost." (2) Rethink: one match does not decide his skill; note what to improve. (3) Relax or exercise: slow breathing or a jog. He could also talk to his coach.
5. Plan a one-week routine to build positive emotions for a student feeling low before exams.
Daily: write 3 good things (gratitude); set one small study goal and tick it (hope); 20 minutes of a hobby (flow); help one person (kindness); a call or walk with a friend (relationships); sleep 8 hours.
Common mistakes
- Thinking emotion is only a feeling: it also has body and behaviour parts.
- Saying all expressions differ across cultures: basic facial expressions are widely shared; display rules differ.
- Believing negative emotions should never be felt: they are useful signals; the aim is to manage, not erase.
- Mixing emotion with mood: an emotion is short and tied to an event; a mood is longer and milder.
