Variations in the Characteristics of Pulse Emissions of a Tursiops truncatus During the Approach Process and the Acoustic Identification of Different Polygonal Shapes
An alternative choice test was used to determine the ability of a 4-year-old Tursiops truncatus to discriminate acoustically a control ring (the positive stimulus) from a regular polygonal frame which was varied between tests. A study was then made of the physical characteristics of the acoustic emissions of the animal during the approach process and the identification of the positive stimulus which the animal was required to bring to the trainer in each trial.
