Discussion Ideas


  • How was the experiment conducted?
    • The experiment was carried out in four parts. All the sounds in the study were requested and performed when Wikie’s head was above water with her blowhole exposed.
      • First, Wikie was trained with a “copy” command.
      • Second, Wikie was trained to copy three orca vocalizations made by her own calf, Moana. These were familiar sounds coming from a familiar source.
      • Third, Wikie was trained to copy five orca sounds she had never heard before, including those sounding like a creaking door and blowing a raspberry. These were new sounds, but familiar vocalizations (pitches and patterns). (Wikie was really good at blowing a raspberry, by the way.)
      • Finally, Wikie was trained to copy six unfamiliar human sounds, including “hello,” “bye-bye,” “one-two” and “Amy.” These were entirely unfamiliar (novel) sounds. Click the Guardian audio to judge how well Wikie imitated these sounds.
