A young female California sea lion (Zalophus californianus) was
successfully trained on a delayed same/different task using two
acoustic stimuli. Approximately 2100 trials (excluding correction
trials) were required to reach a criterion of 90% correct performance
for two consecutive sessions. Subsequent transfer tests with novel
acoustic stimuli showed progressively greater savings in the number
of trials required to reach criterion, with transfer to a novel
stimulus set eventually occurring almost immediately. These results,
the first successful attempt to teach auditory matching to a sea
lion, suggest that the animal acquired the ability to solve new
problems on the basis of an abstract “matching” concept.
Also examined was the effect of increasing the delay interval
between the presentation of the sample and comparison stimuli.
With delays of 2.5 sec or less, performance remained above 90%
correct, but at delays of 12.5 sec, performance dropped to only
61% correct.
