17. Stage Model of Memory Sensory Storage Working Memory Long-Term Memory maintenance organization/elaboration Decay: 0.2-4sDecay: 20-30s 7 (± 2 chunks) Decay? Interference? Audible Visual Haptic Information modality Unprocessed information Symbolic information chunks Semantic and procedural information Adapted from Atkinson & Shiffrin (1968)
