| Summary: | In this study, behavioral plasticity in harbor seals was investigated in spatial reversal learning tasks of varying complexities. We started with a classic spatial reversal learning experiment with no more than one reversal per day. The seals quickly learned the task and showed progressive improvement over reversals, one seal even reaching one-trial performance. In a second approach, one seal could complete multiple reversals occurring within a session. Again, a number of reversals were finished with only one error occurring at the beginning of a session as in experiment 1 which provides evidence that the seal adopted a strategy. In a final approach, reversals within a session were marked by an external cue. This way, an errorless performance of the experimental animal was achieved in up to three consecutive reversals. In conclusion, harbor seals master spatial, in contrast to visual, reversal learning experiments with ease. The underlying behavioral flexibility can help to optimize behaviors in fluctuating or changing environments. |
