Table 4.

The three-point rating scale used by the trainers to evaluate each dolphin’s performance after each training session.

Rating	Dolphin Performance	Definition
1	excellent	The dolphin performed all of the conditioned behaviors correctly at a high level (above the average standard), showed a high level of motivation (e.g., returned to its trainer immediately), was highly focused, and took every fish reward without problems.
2	good	The dolphin performed all behaviors well, but with some minor mistakes, meeting the trainer’s expectations (e.g., conditioned behaviors are performed according to the established standard).
3	poor	The dolphin performed poorly, e.g., did not eat well, left the trainer, interacted with other dolphins, or performed most behaviors below the average standard, refused to perform certain behaviors, or was very distant from the trainer (no or only little eye contact).
