Atkinson and Shiffrin Memory Model

Introduction

• Presented by Etienne.
• Focus on understanding how memories form based on the Atkinson and Shiffrin memory model, also known as the multi-store model.
• Model proposed in 1968 by Richard Atkinson and Richard Shiffrin.

Key Components of the Model

1. Sensory Memory

   • Sensory information continuously taken in by receptors and processed by the nervous system.
   • Three main types:
     • Iconic Memory: Registers through visual stimuli.
     • Echoic Memory: Registers through the auditory system.
     • Haptic Memory: Registers through touch.
   • Sensory information is stored just long enough to be transferred to short-term memory.

2. Short-Term Memory (STM)

   • Capacity for holding a small amount of information in an active, readily available state.
   • Key aspects:
     • Duration: Stored for approximately 20 to 30 seconds.
     • Capacity: Known as the magic number 7 +/- 2, or channel capacity.
   • Information in STM is either forgotten or transferred to long-term memory.

3. Long-Term Memory (LTM)

   • Refers to information stored over an extended period of time.
   • Capable of storing seemingly unlimited amounts of information almost indefinitely.

Conclusion

• The lecture provided a quick overview of the Atkinson and Shiffrin memory model and its process in human memory formation.
• Encouragement to like the video to help spread the message.
