Explain how the word length effect as manipulated by Baddeley fails to support the simple chunking in STM

Identify the components of this system and explain what each of them does and how they are related. Explain how the word length effect as manipulated by Baddeley fails to support the simple chunking in STM hypothesis advocated by Miller. Describe at least two experiments, the results of which support the existence of one or both of the other sub-systems of the executive component. Describe the experimental evidence suggesting that the VSSP has two separable sub-components one purely visual and the other spatial. Discuss the contribution of Farah's work with brain injured patients on visual vs. spatial imagery tasks and its relevance to the issue addressed in "d' above
