Working memory (WM) is the cognitive system that allows the temporary holding of mental representations for use in thought and action. Long-term memory (LTM) refers to our ability to remember a potentially unlimited amount of information over longer time periods. Understanding how these two memory systems interact has important implications for theories of cognition, learning, and education. Here, we examined (a) whether a shared perceptual bottleneck accounts for the relation between WM and LTM accuracy, and (b) whether serial position effects in WM are mirrored in LTM. In two experiments, participants studied sequences of objects at varying set sizes and completed old/new recognition tests for some items immediately after encoding (WM tests) and for other items after all WM trials were completed (LTM tests). In Experiment 1 (
