Introduction to Memory

Quick Fact

Without memory, we wouldn't be able to learn, form relationships, or even function in our daily lives!

What is Memory?

Key Concept

Memory is the persistence of learning over time through the encoding, storage, and retrieval of information.

Key Processes of Memory:

  • Encoding: The process of getting information into our brain. Think of it like typing information into a computer.
  • Storage: The process of retaining that information over time. Imagine this as saving the information on your computer's hard drive.
  • Retrieval: The process of getting that information back out when we need it. This is like opening a file on your computer.

Remember ESR - Encoding, Storage, Retrieval, like a detective (ESR) gathering evidence (encoding), storing it in a case file (storage), and pulling it out to solve a mystery (retrieval).

Models of Memory:

  • Atkinson-Shiffrin Model (Three-Stage Model):

    • Sensory Memory: The immediate, very brief recording of sensory information. Imagine the fleeting image of a sparkler, or the echo of a sound after it's been made. This is your sensory memory at work!

      • Iconic Memory: Visual sensory memory (lasts less than a second).
      • Echoic Memory: Auditory sensory memory (lasts a few seconds).
    • Short-Term Memory: Holds a limited amount of information for a short period (around 20 seconds). Think about trying to remember a phone number you just heard.

      • Can be extended through rehearsal (repeating information).
    • Long-Term Memory: Relatively permanent and limitless storehouse. This is where your childhood memories, the capitals of countries, and your favorite song lyrics are stored!

Common Mistake

Students often assume short-term memory is the same as "working memory,
