Herzing created an open-ended framework for communication, using sounds, symbols and props to interact with the dolphins. The goal was to create a shared, primitive language that would allow dolphins and humans to ask for props, such as balls or scarves.
Divers demonstrated the system by pressing keys on a large submerged keyboard. Other humans would throw them the corresponding prop. In addition to being labeled with a symbol, each key was paired with a whistle that dolphins could mimic. A dolphin could ask for a toy either by pushing the key with her nose, or whistling.
Herzing’s study is the first of its kind. No one has tried to establish two-way communication in the wild.
“This is an authentic way to approach this, she’s not imposing herself on them,” said Lori Marino, the Emory University biologist who, with Hunter College psychologist Diana Reiss, pioneered dolphin self-recognition studies. “She’s cultivated a relationship with these dolphins over a very long time and it’s entirely on their terms. I think this is the future of working with dolphins.”
