Multi-Store Model of Memory
... The working memory model (WMM) was developed by Baddeley and Hitch in 1974. It was developed due to studies suggesting the short term memory (STM) has different stores. Baddeley conducted a study in 1986 which found that STM can perform two tasks at once despite its capacity being full. One task was ...
