| Research Abstract |
The purpose of this study was to investigate the cerebral hemispheric differences in perception and memory of positive, negative, and non-emotional words in normal individuals. The results were as follows.
Results of Experiment 1 and 2 showed that responses to positive and non-emotional words were more accurate in the right visual field than in the left, but no difference was found for negative emotional words. These findings were interpreted as suggesting that the right hemisphere has a processing system for negative emotional words.
Results of Experiment 3 and 4 indicated that the recall of positive and negative emotional words was not different in left and right visual fields although the recall of non-emotional words was better in the right visual field than in the left visual field. The results supported the hypothesis that explicit memory for emotional words was dependent more on the right hemisphere, whereas perception of both emotional and non-emotional words was more dependent on the left hemisphere.
Results of Experiment 5 and 6 showed that the stroop interference of positive and negative emotional words was larger than that of non-emotional words, and that the stroop interference of positive and negative and non-emotional words was not different in left and right visual fields, although the recall of non-stroop words was better in the right visual field than in the left visual field. These findings were interpreted as suggesting that the stroop interference of emotional words was larger in the left hemisphere.
The present study on the cerebral hemispheric differences in perception and memory of emotional words indicated that the memory for emotional words was dependent more on the right hemisphere, although the perception of both emotional and non-emotional words was more dependent on the left hemisphere.
