Problem 4

Suppose that you have just been introduced to five students from another college. Using the information on pronunciation time and semantic similarity, why would you find it difficult to remember their names immediately after they have been introduced? How could you increase the likelihood of your remembering their names?

Problem 5

According to the discussion of Baddeley's approach, working memory is not just a passive storehouse. Instead, it is like a workbench where material is continually being handled, combined, and transformed. Why is the workbench metaphor more relevant for Baddeley's model than for the Atkinson-Shiffrin model?

Problem 10

For many decades, researchers in the area of human memory primarily studied college students who are enrolled in introductory psychology courses. Why would the research on working memory not be applicable for someone who is currently experiencing major depression?
