- Evidence supporting the WMM
- Doing two tasks using the same or different components
- Task 1 occupied the CE, task 2 involved either the articulatory loop or both the CE and the AL or no additional task
- Task 1 was slower when given a task involving both the CE and AL
- Speed on task 1 was the same whether using the articulatory loop or no extra task.
- Doing two tasks that involve the same component causes difficulty. When different components are used performance is not affected.

- Central Executive
- The same brain areas were active in either dual- or single-tasks conditions
- Significantly more activation in the dual-task condition indicating that increased attentional needs were reflected in brain activity
- The same brain areas were active in either dual- or single-tasks conditions
- Phonological loop and articulatory process
- People cope better with short words than long words in working memory
- PL holds the amount of information you can say in 2 seconds
- Word Length effect disappears if a person is given an articulatory suppression task
- The repetitive task means you can't rehearse the shorter words more quickly than the longer ones
- People cope better with short words than long words in working memory
- Visuo-spatial sketchpad
- Given difficult task (1) and easy task (2) whilst doing a visual tracking task
- Episodic Buffer
- Shown words and then asked for immediate recall, better when sentences (related words) than unrelated words
- Immediate memory store for items that aren't visual, phonological and that draw on long-term memory
- Shown words and then asked for immediate recall, better when sentences (related words) than unrelated words
- Brain Damaged Patients
- SC-unable to learn word pairs that were presented out loud
- Doing two tasks using the same or different components
