A comparative study of working memory: Immediate serial spatial recall in baboons (Papio papio) and humans

► Successful implementation of immediate serial recall task in free ranging baboons. ► Immediate serial recall of up to 6 items assessed in baboons and humans. ► Larger memory capacity in humans but serial position effects in both species. ► Experimental manipulation of path length and organization of recall sequences. ► Humans but not baboons benefit from sequence organization.
