Short-term memory (STM)

• Short-term memory - The limited capacity memory store
• Short-term memory: Coding

  • Acoustically (sound)
• Short-term memory: Duration

  • 18 seconds (unless information is rehearsed)
• Short-term memory: Capacity

  • 7 ± 2 items
  • Limited capacity store because it can only contain a certain number of things before forgetting occurs
• Maintenance rehearsal - Occurs when we repeat (rehearse) material to ourselves over and over again. We can keep the information in our STMs as long as we rehearse it. If we rehearse it long enough, it passes into LTM
