This chapter addresses the multiple timescales of memory. It explains the savings and spontaneous recovery of memory. It shows that animals display patterns of learning and forgetting. The active and passive properties of memory are detailed. This chapter reveals that error-driven learning engaged processes that adapt with multiple timescales and that once practice ends and the memory is placed in a passive state, passage of time transforms some of the fast states into slower states that resist change when the task again resumes and the memory is reactivated. It illustrates that the multiple timescales of memory during classical conditioning are partly due to different rates of learning in the cerebellar cortex and nuclei.

Keywords:   multiple timescales, memory, savings, spontaneous recovery, error-driven learning, classical conditioning, cerebellar cortex, nuclei
