Question 11

based on the description below:
A researcher is interested in testing how brain tumors influence in Wernicke's area (i.e., a region of the brain). Past research indicates that damage to Wernicke's area often leads to an inability to produce and understand basic nouns and verbs. The researcher's study includes three phases. In phase 1, she recruits fifteen individuals who have brain tumors around Wernicke's area to serve as her sample of individuals with brain tumors and fifteen individuals without brain tumors to serve as controls. In phase 2, she will administer a task to examine how participants in both groups' brain activation might differ in a naming task of common objects that participants will be viewing during the study, and participants will also be asked to produce the nouns and verbs that are associated with the picture. In phase 3, the researcher examines how participants in both groups might differ in a comprehension task in which participants will be listening to audio stimuli and selecting images that correspond to a description. Participants will be paid for their participation.
