Baddeley's Classic Study (1966b)
Ever wondered why you can remember song lyrics perfectly but struggle with your shopping list? Baddeley's groundbreaking study helped explain exactly how our long-term memory processes information. He discovered that our brains don't just store memories randomly - there's actually a sophisticated system at work.
Baddeley tested 72 Cambridge volunteers using four different word lists: some with similar sounds (like "cat, bat, hat") and others with similar meanings (like "big, large, huge"). The clever bit was using an interference task - participants had to do mental arithmetic to stop their short-term memory from helping out. This meant he could study long-term memory in isolation.
The results were brilliant: people struggled massively with semantically similar words (remembering only 58% correctly) but had no trouble with acoustically similar ones (85% accuracy). This proved that long-term memory encodes information by meaning rather than sound - which is why mindmaps work so well for revision!
Top Tip: Use semantic links when revising - connect new information to things you already know rather than just repeating facts.
