Punctuation Picks Up Spoken Surprise Functions

  • Writers borrowed punctuation like the exclamation mark to encode spoken surprise and emphasis in text; its meaning has broadened.
  • Exclamation marks now often signal friendliness in informal writing, while periods can carry anti-surprise or flat tone in messaging.
ANECDOTE

Emoji Expand The Nuance Of Surprise

  • Emoji have evolved to express nuanced surprise: open-mouth, hand-over-mouth, bulging eyes, and exploding head cover different intensities.
  • Gretchen notes an exploding head emoji serves metaphorical emphatic surprise when intonation is unavailable.

The N400 Shows Surprise In Brain Waves

  • EEGs detect a consistent N400 negative deflection ~400ms after a semantically unexpected word, revealing rapid automatic surprise processing.
  • Classic examples include 'they ate cake and socks' or 'he spread the warm bread with socks' producing the N400 spike.
