Our memory has three basic functions: encoding, storing, and retrieving information. Encoding is the act of getting information into our memory system through automatic or effortful processing. Storage is retention of the information, and retrieval is the act of getting information out of storage and into conscious awareness through recall, recognition, and relearning. There are various models that aim to explain how we utilize our memory. In this section, you’ll learn about some of these models as well as the importance of recall, recognition, and relearning.

To get a good overview of all of these concepts and to pique your interest, you may choose to begin this module by watching John Gabrieli’s lecture on memory. Listen for some key vocabulary terms you’ll learn about soon, particularly:

  • the three-stage model of memory
  • short-term memory
  • serial position effect
  • primacy
  • recency
  • Ebbinghaus forgetting curve
  • proactive interference
  • retroactive interference
  • flashbulb memories
  • false memories
