Topic: spatial configurations

Primates excel at reasoning about physical scenes comprised of objects, flexibly generalizing to novel compositions of objects. Many cognitive theories attribute this capacity to structured representations in working memory called “object files” that encode object features in independent subspaces that can be readily retrieved and processed. However, these theories remain largely un-tested in the primate brain. We developed a task for non-human primates (NHPs) that requires remembering the positions and identities of multiple objects on a visual display. In some conditions the objects move und
