Activation of memory retrieval after weak learning (WL), during either the short- or intermediate-term stages of memory in day-old chickens, resulted in the strengthening of the memory to levels normally associated with strong learning. Administration of the calcium channel antagonist lanthanum chloride, the glutamate receptor agonist monosodium glutamate, or the N-methyl-D-aspartate glutamatergic receptor antagonist AP5 prevented strengthening of a WL memory by reminder-activated memory retrieval. The results of this study are discussed in light of our recent findings suggesting two phases of memory retrieval in the day-old chick. The results are consistent with the proposition that a memory undergoing the processes of formation may be modified to include information gleaned at the time of memory retrieval and that a second phase of memory retrieval may be responsible for such modification.
