| Outline of Final Research Achievements |
Running in an activity wheel or swimming in a water pool yields learned avoidance of the taste substance (e.g., saccharin solution) consumed before the activity in the laboratory rat. Although running-based taste aversion has been demonstrated in many laboratories with a variety of procedures, swimming-based taste aversion is not fully established. The present research suggested that different physiological processes are involved in running- and swimming-based taste aversions. Furthermore, it revealed that the generality and robustness of swimming-based taste aversion are limited, because this learning is hard to detect in other species (i.e., mice). Collateral findings with rats include: (1) water temperature has little effect on swimming-based taste aversion, (2) swimming in flavored water results in weak avoidance of that flavor, (3) gastrointestinal discomfort (i.e., nausea) mediates running-based taste aversion.
