Dr. Vendort has examined the activation of a certain brain region located in the parietal cortex. As indicated using fMRI imaging techniques, this region of the brain activates each and every time a person is asked to draw a picture.
Dr. Vendort concludes
that this region of the brain is the location for artistic ability. In a subsequent study
conducted using participants who have suffered brain damage to the same region of the
parietal cortex, as previously mentioned, participants were still able to draw pictures of a
variety of objects. Which of the following can be said about Dr. Vendort's experiment?
A) It is valid, but lacks reliability
B) It indicates validity and reliability
C) It indicates neither validity nor reliability
D) It indicates reliability, but not validity
Question 2
