This topic introduces the fundamental mechanics of how humans process information. Students examine the three stages of memory: encoding, storage, and retrieval. By understanding how we convert sensory input into mental representations (visual, acoustic, and semantic), students gain insight into why certain information sticks while other data is lost. This forms the bedrock of the AQA GCSE Psychology specification, linking directly to later studies on brain structure and cognitive development.

Set up three stations where students attempt to memorise word lists using different encoding methods: one visual (images), one acoustic (rhymes), and one semantic (placing words in sentences). After completing all stations, students compare their recall rates to see which method was most effective.
Students recall a time they had a 'tip of the tongue' experience. They work in pairs to identify whether the failure happened at the encoding, storage, or retrieval stage, using specific psychological terminology to justify their choice.
What is the difference between storage and retrieval?
Groups are given a complex set of information to 'teach' to the class. They must design a strategy that uses at least two types of encoding and then test the class's retrieval 20 minutes later to evaluate their success.
Memory works like a video camera that records everything perfectly.
Memory is an active, selective process where we only encode specific details. Using peer-led memory tests helps students see that they often miss details or 'fill in' gaps, proving that encoding is not a passive recording.
Forgetting is always a total loss of information from the brain.
Often, the information is still in storage but cannot be retrieved due to a lack of cues. Classroom demonstrations of cued recall versus free recall quickly show students that 'forgotten' info is often just inaccessible.
