The experience of time, and more particularly of duration, has been studied rather separately from its functional fundament: the memory process. Yet, in the past few years some rather intriguing patterns of connection have emerged. Especially the effect of the usual distinction between immediate memory (IM), short term memory (STM) and long term memory (LTM) (Shiffrin and Atkinson 1969; Norman 1970) seems to provide some conceptual cement to link the two fields: time and memory.
