Abstract:
Training rats with serial presentations of two taste solutions before confinement in an activity wheel (X-->A-->running) resulted in weak aversion to taste X, compared to a training procedure without the presentation of A. Demonstration of the overshadowing effect in the present study provides another parallel feature between running-based taste aversion learning and Pavlovian conditioning preparations including poison-based taste aversion learning. It also indirectly supports the claim that cue competition causes degraded contingency effect and cover-cue effect in rats' running-based taste aversion (Nakajima, 2008).
