Method:
This study examines group and individual performance on word list recall and recognition in 52 patients with unilateral right hemisphere stroke.
Results:
On the California Verbal Learning Test, List A, Trials 1-5, patients achieved a mean score of 30.31 (SD = 13.94), which is below the mean standard score of 50 (SD = 10) in a normal population. Patients demonstrated below-average performance on other immediate and delayed recall trials and on free- and cued-recall tasks. 67% of patients showed improved performance across learning trials.
Conclusion:
Results provide support for encoding deficits with reduced rate of learning and inconsistent recall across trials.

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...
