- Baddeley (1966b)
- Aim - to investigate the influence of acoustic and semantic similarity on long-term memory for word sequences.
- Procedure - lab experiment, independent groups design, both genders, 20 per group, recruited for the Applied Psychology Research Unit subject panel, 4 lists of 10 words: list A acoustically similar, list B acoustically dissimilar, list C semantically similar, list D semantically dissimilar. Asked to remember the words and then completed a 15 minute interference task and then was tested.
- Results - acoustically similar words were much harder to recall using STM than words that were acoustically dissimilar. Semantically similar words were more difficult to learn and recalled less semantically similar words.
- Conclusion - STM is largely encoded acoustically and LTM is largely semantic.
