Key standards

Visual physical commonsense (V-PC)

  • A person stands in a quiet room and visibly lifts a large seashell to their ear.
  • The seashell retains its shell identity and shape throughout the lift.

Audio physical commonsense (A-PC)

  • A soft steady broadband ocean-like whoosh begins when the shell reaches the ear and continues steadily.
  • The audible whoosh is produced by the shell resonating at the ear.

Cross-modal physical commonsense (AV-PC)

  • The onset of the whoosh coincides with the seashell reaching the ear.
