Non-Verbal Behaviour Perspectives

Theoretical Outline

Non-verbal behaviour is explained by two major opposing perspectives on its origin:

1

Evolutionary Theory (Darwin)

Suggests non-verbal communication is innate and adaptive for survival.
2

Learning Theories

Suggests non-verbal behaviour is learned through social interaction and culture.

Key Terminology

Understanding these core terms is vital when assessing non-verbal cues:

🧬

Innate

Biologically hardwired, inborn.
🛡️

Adaptive

Provided survival advantages.
🌍

Universal

Recognized across all cultures.
🧠

Learned

Shaped by social interaction/culture.

Case Study: Yuki’s Emoticon Research

Cultural Differences in Interpretation

Yuki et al. (2007) studied cultural differences in interpreting emoticons (text-based smileys).
  • Japanese participants focused mainly on the eyes to judge the emotion of emoticons since Japanese emotional expressions tend to emphasize the eyes.
  • American participants focused more on the mouth region, consistent with Western culture’s emphasis on smiles.
This study demonstrates cultural learning shapes how people interpret even symbolic facial cues in digital communication.

Evidence: Innate vs. Learned

✅
Evidence for Innate Origin (Evolutionary)
  • Neonates show facial expressions similar to adults even hours after birth.
  • Sensory-Deprived Individuals (blind/deaf) show the same basic facial expressions.
  • Cross-Cultural Studies (Ekman) support the biological universality of basic emotions.
❌
Evidence for Learned Origin (Cultural)
  • Cultural Differences in Gestures and Norms (meaning of thumbs up varies).
  • Yuki’s Study showed cultural lenses shape interpretation of emoticons.
  • Social Learning and Modeling: Children imitate adults’ non-verbal responses.

Synthesis of Findings

The core takeaway regarding non-verbal communication:

💡

Conclusion: Both innate biological drives and learned cultural influences fundamentally shape non-verbal communication, leading to universal expressions modified by culturally specific displays.

Non-Verbal Behaviour Theories Deck
Term
Main Perspectives

What are the two main perspectives explaining non-verbal behaviour?

Answer
Explanation

Evolutionary theory (innate and adaptive) and learning theories (learned through social interaction and culture).

Term
Darwin's Theory

According to Darwin, why did non-verbal communication evolve?

Answer
Reason

Because it provided survival advantages by signaling danger, submission, aggression, and helping social cooperation.

Term
Emotional Expressions

What did Darwin say about emotional expressions across cultures?

Answer
Universality

They are universal and biologically based, like fear, anger, happiness, surprise, sadness, and disgust.

Term
Innate Evidence

What evidence supports that non-verbal behaviour is innate?

Answer
Evidence

Neonates show facial expressions at birth, sensory-deprived individuals show universal expressions, and cross-cultural recognition of emotions.

Term
Learned Evidence

What evidence supports that non-verbal behaviour is learned?

Answer
Evidence

Cultural differences in gestures, Yuki’s emoticon study, and social learning through imitation and feedback.

Term
Yuki’s Emoticon Study

What was a key finding of Yuki’s emoticon study?

Answer
Finding

Japanese focus on eyes for emotion interpretation, Americans focus on the mouth, reflecting cultural differences.

Term
Raised Eyebrows

How do raised eyebrows serve as an adaptive non-verbal signal?

Answer
Function

They make the eyes more visible to gather more information and signal surprise.

Term
Social Learning

How do social learning theories explain non-verbal behaviour?

Answer
Explanation

People learn non-verbal cues by observing and imitating others and through social feedback.

🧠 Non-Verbal Behavior Quiz

1. Which theory suggests that non-verbal behaviour is biologically hardwired for survival?

Evolutionary theory posits that non-verbal cues evolved to aid survival and are innate.

2. Which of the following is NOT evidence supporting that non-verbal behaviour is innate?

Cultural differences indicate learning, not innate behaviour.

3. What did Yuki’s study on emoticons reveal about cultural differences in interpreting emotions?

Reflects cultural differences in emotion expression and interpretation.

4. According to Darwin, the raised eyebrows in surprise help because they:

Raised eyebrows widen eyes to signal surprise and improve situational awareness.

5. Social learning theory claims that:

Social learning emphasizes environmental and cultural influences.
