Neuroscientists who have examined the visuospatial sketchpad have discovered that
a. visual tasks typically activate the right hemisphere, whereas spatial tasks typically activate the left hemisphere.
b. visual and spatial tasks typically activate the right hemisphere of the brain.
c. visual and spatial tasks are apparently converted into a verbal code, because they primarily activate the left hemisphere of the brain.
d. there is no clear correspondence between visuospatial tasks and the patterns of brain activation.
Question 2
In a study on working memory, one group of participants repeated a sound, thereby blocking acoustic coding for other material. This research showed that
a. working memory disappeared completely.
b. when acoustic coding was blocked, people often used visual coding.
c. acoustic coding was even more likely in long-term memory than in working memory.
d. semantic coding was the dominant mode in working memory, whereas acoustic coding was more likely in long-term memory.
