The performance of goats in triple choice delayed response tasks.

Goats have been successfully trained in types of triple choice delayed response situations. Their levels of performance indicated that they are able to solve delayed response tasks very successfully and can make correct choices in a post-delay response reward design after delays of 30 min, which is considerably longer than has been previously reported for dogs and cats. Goats do not readily approach and investigate novel stimuli and require a complex compound stimulus in the delayed response situation. They have been shown to be very useful experimental animals in the study of the mechanisms involved in recent memory.
