It has been reported that in reward serial learning rats can form an inter-item association between adjacent items and between remote items. In addition, by using a preceding series as discriminative cues they can discriminate a following series. These different types of association learning were examined in mice with three experiments of reward serial learning. In Experiments 1 and 2 the mice learned to form inter-item associations between adjacent items and between remote items. They responded differentially, according to their anticipation of a reward magnitude. In Experiment 3, however, despite considerable training, the mice failed to master series discrimination learning when two preceding series signaled a different subsequent series. These results suggest a basic ability of mice for item association learning but a restricted cognitive capacity to form a series chunk.
