When material is processed in the visuospatial sketchpad, similar-sounding items can be confused with one another. c. The central executive has several component processes, including the task of resolving acoustic confusions. d. This research suggests that the phonological loop plays a relatively minor role in working memory.

A child has two favorite glasses: a tall, skinny one with a picture of a giraffe on it and a short, fat one with a picture of a hippopotamus on it. When her mother pours her some milk using the "hippo" glass,
