Key standards

Visual physical commonsense (V-PC)

  • The wire is plucked twice, and between the two plucks the wire visibly slackens.
  • The object strung between the two posts is a thin metal wire.

Audio physical commonsense (A-PC)

  • The second plucked tone is noticeably lower in pitch and sloppier in timbre than the first plucked tone.

Cross-modal physical commonsense (AV-PC)

  • Each plucked tone in the audio aligns in time with a visible pluck of the wire.
  • The lower-pitched and sloppier tone corresponds to the wire in its slackened state.
  • The higher-pitched and clearer tone corresponds to the wire in its taut state.
