Memory & Encoding Models – AP Psychology

1. In the Atkinson-Shiffrin model, information flows:

LTM → STM → Sensory Sensory → STM → LTM STM → Sensory → LTM All stores operate independently

2. The capacity of short-term memory is approximately:

2±1 items 7±2 items Unlimited 20±5 items

3. Semantic encoding is most effective because:

It uses the least effort It processes meaning deeply, creating richer associations It only involves visual processing It bypasses short-term memory
