When a key was pressed, it resulted in the underwater projection of a computer-generated whistle associated with that key followed by a human either offering the dolphin an object (ball or ring) or an action (rub) associated with that particular key and sound.
This allowed Lilly to open a second facility in the Caribbean named the Dolphin Point Laboratory. Otherwise, the world would be a different place. Responses to anomalous gestural sequences by a language-trained dolphin: Evidence for processing of semantic relations and syntactic information. It is understood that dolphins do not breathe air automatically like we do. Phoenix’s initial vocabulary consisted of 32 symbols and Ake’s 30 symbols (Herman 1986). Thus, if the trainer signed HOOP+QUESTION and there was hoop in her pool, Ake would press the Yes paddle indicating that the named object was present.

Following this, she showed that she could produce facsimiles of these sounds when the physical object associated with the sounds was shown to her. In situations like Peter’s where life becomes unbearable, dolphins can decide to call it quits by taking one last breath and sinking to the bottom of the body of water.[10].

After Peter was transferred to his new home in Miami, Florida, he fell into a depression. First, she wanted to record notes on interspecies isolation.

Herman (1986) reported that Phoenix and Ake performed wholly correctly, meaning that they interpreted accurately each of the words in a sentence as well as its structure on 67.5% of 191 lexically novel sentences and on 65.4% of 214 lexically novel sentences, respectively.

A much larger set of appropriate facsimile productions of whistles for ball, ring, rub and a combination of the separate whistles for ball and ring into a single continuous whistle were recorded in the context of a dolphin being in contact with the object or objects associated with that whistle or whistle combination. The production of signature whistles in captivity when one dolphin from a group voluntarily isolates itself, or the exchange of signature whistles between individuals in the wild before joining other groups, suggests that these whistles can be used to maintain cohesion between group members (Janik and Slater 1998). Several types of structurally novel sentences were presented to each dolphin including for the first time for Ake, four-word sentences. Individualized whistle contours in bottlenosed dolphins (. Terrace, H. S., Petitto, L. A., Sanders, R. J., & Bever, T. G. (1979). However, thus far there is no evidence of the use of signature whistles in different syntactic forms, and no evidence beyond signature whistles of the natural vocalizations in a dolphin’s repertoire being used to refer to objects, locations, or events. Alternatively, with no hoop in her pool, Ake would press the No paddle indicating that the named object was absent. First, each semantic element within a sentence whether M, DO, IO, or R could be fulfilled by multiple exemplars within a category. Bottlenose dolphins develop novel individually unique whistle contours termed “signature whistles” (Sayigh et al. However, while details were provided on the dolphin’s spontaneous pointing behavior, suggesting that it was referential in character (Xitco Jr et al. The use of the inverse syntactic rule for relational sentences of three, four, and five words in Ake’s language not only tested for dolphin mental flexibility in understanding different syntactic structures, but also examined sentence parsing in which the question of how to treat the initial object symbol of a sentence was conditional on the remaining elements. A key feature of language is the ability to understand linguistic references to arbitrary objects (i.e., those that are not biologically or ecologically meaningful) that are displaced in space and time (Hockett 1960).
