Definition
This is a method that can be used to determine in the rat the motivational valence of a taste without having the test subject actually ingest the fluid. Ralph Norgren and Harvey Grill discovered that rats show distinct orofacial (movement of the mouth and tongue and opening of the mouth, gaping and face washing and wiping) reactions to the intraoral application of sapid solutions. The reactions observed can be characterized as appetitive or aversive, depending on whether the fluid evokes an ingestive or rejective reaction. This test can be used as a method to assess tastes paired with drugs that produce conditioned taste preferences or taste aversions.
