Evidence that Non-Verbal Behaviour is Learned
Developmental Progression: Research into child development shows that infants do not possess the full repertoire of adult non-verbal cues. As children age, their non-verbal behaviors become increasingly aligned with those of their primary caregivers and peers, suggesting a gradual acquisition process.
Modeling and Mimicry: Children learn by observing the 'non-verbal style' of their environment. If a child grows up in an environment where expressive hand gestures are common, they will adopt that style, whereas a child in a more reserved environment will learn to minimize their physical movements.
Social Feedback Loops: When a child uses a gesture correctly and achieves a desired outcome (like getting attention), the behavior is reinforced. Conversely, if a gesture is met with confusion or social disapproval, the child learns to modify or abandon that specific non-verbal cue.
| Feature | Learned Non-Verbal Behaviour | Innate Non-Verbal Behaviour |
|---|---|---|
| Origin | Social environment and culture | Biological evolution and genetics |
| Universality | Varies significantly by region/group | Largely consistent across humanity |
| Examples | Emblems (OK sign), Proxemics | Reflexive smiles, Startle response |
| Acquisition | Gradual through socialization | Present at birth or early infancy |
| Flexibility | Highly adaptable and changeable | Relatively fixed and automatic |
Emblems vs. Affect Displays: It is critical to distinguish between 'Emblems' (learned gestures with specific meanings) and 'Affect Displays' (facial expressions of emotion). While the expression of a basic emotion might be innate, the rules for when to show that emotion are learned.
Micro-expressions vs. Social Smiles: A micro-expression is an involuntary, innate flash of true emotion, whereas a 'social smile' used during a polite greeting is a learned behavior used to facilitate social harmony.
Identify the 'Emblem': In exam scenarios, if a gesture has a specific 'dictionary definition' that changes between countries, it is always evidence for the learned perspective.
Look for Developmental Clues: If a question mentions a behavior that changes as a child grows or interacts with different groups, focus on socialization and reinforcement as the underlying mechanisms.
The 'Blindness' Argument: A common exam point is comparing sighted children with children blind from birth. If both groups show the same behavior (like a smile), it suggests the behavior is innate. If only sighted children show it, it is evidence that the behavior is learned through visual observation.
Contextual Analysis: Always check if the behavior is described as 'universal' or 'culture-specific.' Universality points to biology; specificity points to learning.
The Universality Trap: A common mistake is assuming that because we understand a gesture (like a nod for 'yes'), everyone in the world does. In reality, many gestures are 'false friends'—they look the same but have different learned meanings in different cultures.
Over-simplification of Emotion: Students often think all facial expressions are innate. While the capacity to make the face is innate, the habit of using that face in specific social situations is a learned behavior governed by cultural display rules.
Ignoring Sub-cultures: Learning doesn't just happen at the national level. Professional groups (like doctors or athletes) and social sub-cultures develop their own learned non-verbal codes that outsiders may not understand.
