Conditioned taste aversions and latent inhibition in Egyptian spiny mice and Long-Evans rats.
The acquisition and extinction of a conditioned taste aversion in Egyptian spiny mice and Long-Evans rats was compared during 20 posttest sessions using a cross-over design and double-blind control procedures. Spiny mice preexposed to a sucrose CS demonstrated more latent inhibition and a faster rate of extinction than did Long-Evans rats preexposed to the same CS. Preference indices did not differ between control animals or as a function of gender. The present results are the first report of the effects of latent inhibition on learning taste aversion in Egyptian spiny mice.
