Researchers interested in memory retrieval trained rats to do a water maze task, lesioned their hippocampi, and then tested their memory. The lesions affected learning and memory in interesting ways, which should lead to good follow-up research. I won't bother abstracting it, there's a nice synthesis here.
Another study, which highlights something we all know already (that standardized intelligence/aptitude testing is crap), examined list recall from visual versus aural input modalities. It turns out that recall is highly modality-dependent: the auditory system seems to be naturally 'primed' for sequential memory, whereas the visual system is not. And both seem to be independent of actual linguistic ability.
