Researchers studying learning and memory in the day-old chick have developed a one-trial taste avoidance learning task, in which a chick pecks a bead coated with an aversive-tasting liquid such as methylanthranilate. The current study examined, in two experiments, whether chicks could demonstrate learning of an appetitive version of the one-trial task, and how long this memory might last. The results demonstrate that chicks show significantly decreased latencies to peck a test bead similar to that pecked at training coated with water, and that this memory lasted for at least 6 h after training. These results demonstrate that this appetitive task produces significant learning.
