Facial Expressions in ASL

Why This Matters

In ASL, facial expressions aren't optional add-ons—they're grammatical markers that change the meaning of your signs entirely. Think of them as the punctuation, tone, and emphasis of spoken English all rolled into one. You're being tested on your ability to recognize that ASL is a complete, rule-governed language with non-manual signals (NMS) that serve specific linguistic functions, not just emotional decoration.

Understanding facial expressions means grasping a core principle: ASL conveys information through multiple channels simultaneously—hands, body, and face all work together. Don't just memorize which expression goes with which situation; know why each expression exists and what grammatical or semantic function it serves. This distinction between grammatical markers and emotional expressions will come up repeatedly in assessments.

Grammatical Markers for Questions

Facial expressions in ASL don't just show emotion—they indicate sentence type. These markers are required, not optional, and using the wrong one changes your meaning entirely. The eyebrow position signals to your conversation partner what kind of response you're expecting.

Raised Eyebrows for Yes/No Questions

• Required grammatical marker—without raised eyebrows, your question becomes a statement
• Signals closed-ended inquiry expecting only affirmative or negative responses
• Held throughout the entire question, not just at the end—timing matters for clarity

Furrowed Brows for WH-Questions

• Lowered, drawn-together eyebrows mark questions requiring detailed answers (who, what, where, when, why, how)
• Creates visual contrast with yes/no questions, preventing confusion between question types
• Often accompanied by a slight head tilt forward, reinforcing the interrogative function

Conditional and Hypothetical Markers

ASL uses specific facial expressions to establish logical relationships between ideas. These non-manual markers function like "if...then" constructions in English, setting up conditions before stating outcomes.

Tilted Head for Conditional Statements

• Marks the "if" clause of a conditional sentence—the condition comes first, then the result
• Often combined with raised eyebrows during the conditional portion, then neutral face for the outcome
• Essential for complex sentence structures like "If it rains, I'll stay home"—without the head tilt, the relationship between clauses is unclear

Size and Quantity Modifiers

These expressions function as adverbs or adjectives, modifying the signs they accompany. Rather than signing separate words for "big" or "small," ASL incorporates this information directly into facial expression.

Puffed Cheeks for Large Size or Quantity

• Inflates meaning—transforms a neutral sign into one conveying largeness, abundance, or intensity
• Can indicate "very" or "a lot" depending on context, adding degree information
• Often paired with enlarged hand movements, creating a cohesive visual representation of size

Pursed Lips for Small Size or Precision

• Contracts meaning—signals smallness, thinness, or careful precision
• Frequently appears with fingerspelling or technical signs requiring exactness
• Creates clear opposition to puffed cheeks, allowing signers to modify any noun for size without additional signs

Emotional Expression Markers

While grammatical markers are rule-governed, emotional expressions add affect and intensity to communication. These overlap with universal human expressions but serve specific communicative functions in ASL discourse.

Wide Eyes for Surprise or Emphasis

• Signals unexpected information or highlights critical points in a narrative
• Functions as a discourse marker, telling your audience "pay attention to this"
• Intensity scales with eye width—slightly wide for mild surprise, extremely wide for shock

Squinted Eyes for Doubt or Suspicion

• Conveys skepticism about information being received or discussed
• Can function as a question on its own, asking "really?" without any hand signs
• Indicates need for clarification, prompting the other signer to explain further

Mouth Open for Shock or Disbelief

• Marks extreme emotional reaction—stronger than wide eyes alone
• Often combined with other markers like raised eyebrows or backward head movement
• Adds narrative drama in storytelling, a key component of ASL literature and Deaf culture

Negative Affect Markers

These expressions communicate aversion, frustration, or resistance. They often appear in contexts where the signer is describing problems, expressing disagreement, or conveying strong negative reactions.

Nose Wrinkle for Disgust or Distaste

• Universal expression adapted for ASL—immediately communicates aversion
• Can modify signs for food, situations, or ideas to indicate dislike
• Stronger than simply signing "don't like"—adds visceral, emotional weight

Tight Lips for Determination or Frustration

• Dual function—can show resolve (positive) or irritation (negative) depending on context
• Often accompanies signs about effort, struggle, or persistence
• Intensity indicated by lip compression—tighter lips signal stronger emotion

Self-Check Questions

1. Which two facial expressions mark questions, and how do they differ in the type of response expected?

2. If you wanted to sign "I have a tiny dog" versus "I have a huge dog" using the same hand signs, which facial expressions would you use for each?

3. Compare and contrast wide eyes and squinted eyes—what emotional or communicative functions does each serve?

4. Why is the tilted head considered a grammatical marker rather than just an emotional expression? What sentence structure does it create?

5. A classmate signs a question but keeps a neutral face. What's missing, and why does it matter for ASL grammar?
