In the 1960s, researchers began to understand memory as operating under two systems: a short-term one handling information for mere seconds, and a long-term one for managing information indefinitely. Short-term memory, they found, wasn't simply a 'filing cabinet,' but appeared to work on cognitive tasks. Seeking evidence that short-term memory really was 'working,' Baddeley and Hitch conducted 10 experiments, concluding that working memory consists of three parts: one component handling what we hear and another what we see acting together as short-term storage, while a third component processes and manages the first two, influencing attention, reasoning, reading, comprehension, and learning.
