Purpose:
This longitudinal study examines performance of individuals with right hemisphere damage (RHD) on the California Verbal Learning Test (CVLT).
Method:
18 participants were administered the CVLT during the acute phase (<3 months post onset) and then at subsequent times up to 2 years post onset.
Results:
Using List A, Trials 1-5, as a global measure of learning, participants at first testing demonstrated recall skills below the mean standard score of 50 (M = 32.56, SD = 13.90). There was significant improvement between initial and second testing (t = -2.92, p = .01). Changes between second and third testing and third and fourth testing were not significant.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
