Visual physical commonsense (V-PC)

  • A busy highway with visibly moving vehicles is shown, and a person visibly shouts into a phone next to it during the same scene.

Audio physical commonsense (A-PC)

  • The traffic roar is louder than the voice throughout the phone call and stays active during the shouting segments.

Cross-modal physical commonsense (AV-PC)

  • The visible shouting mouth movements coincide in time with faint shouted-voice segments underneath the traffic roar.
