Learn How Dolphins Can Think In Sentences
Dolphin Quest Oahu trainers are teaching their animals to think in "sentences." Rather than doing a single behavior, the dolphins will perform a sequence of behaviors in the specific order requested. For example, rather than simply waving his tail, a dolphin will wave his tail, then jump and finish with a raspberry vocalization. To add to the fun, the dolphins are also learning to only do the series of behaviors when given a "go" signal. Otherwise, they wait and keep their attention on their trainers.
The entire wait-and-go training game consists of hand signals. Although dolphins have excellent hearing and can hear sounds undetected by the human ear, there is no evidence that dolphins can discriminate words, therefore trainers use hand signals and body language to communicate with them.
To let the dolphin know to wait for additional information, a trainer holds up both hands with the palms facing the dolphin. 
The trainer can then give multiple hand signals for various behaviors. The dolphin doesn’t move until he sees the "go" hand signal, which is the trainer’s hands turning into two fists and bumping against each other.
As the dolphins become more advanced with wait-and-go, trainers will gradually add behaviors to the sequence. In addition, the behaviors and the behavior sequence change so that the dolphins are not simply memorizing the pattern of behaviors.
