Understanding timing
Microexpressions vs. macroexpressions
The most useful starting distinction is duration. A brief expression gives you less time to notice the same facial movements.
Same shape. Less time.
Watch a surprise expression at two exposure times. Each replay starts and ends with the same neutral face.
Brief does not mean faint
A microexpression can involve a clear change that disappears quickly. A subtle expression may involve only a small movement, even when it stays visible longer. Speed and intensity are different things to observe.
| Pattern | What to notice | Practice approach |
|---|---|---|
| Microexpression | A change visible for a fraction of a second. | Learn the shape slowly, then shorten exposure. |
| Macroexpression | A longer expression with more time to inspect it. | Describe the brows, eyes and mouth separately. |
| Subtle expression | A low-intensity or partial movement. | Compare the changed region with a neutral example. |
How short is a microexpression?
The Paul Ekman Group describes microexpressions as lasting half a second or less, and macroexpressions as lasting roughly half a second to four seconds. Definitions can differ across research settings; the demonstration above simply contrasts 0.2 seconds with 2 seconds.
Start with the visual expression chart. Once you can explain a pattern without rushing, try Beginner practice and shorten the exposure when you feel ready.
Try a comparison, not a guess
Replay the longer example and name one change in the brows, one in the eyes, and one in the mouth. Now play the shorter example. Which change caught your attention first? If you missed it, return to the slower replay rather than repeatedly guessing.
For another useful distinction, compare fear and surprise. Both can involve wide eyes, so the mouth and brow shape matter.
