为了评估获取情绪词含义的大脑功能不对称性，以英语为母语的人被要求对在他们的左或右视野中短暂闪现的情绪词、中性词和非词做出词汇决定，即分别由他们的右或左视觉皮层感知。情绪负面词在每个视野中出现的总体概率为 12.5%，预计会引发 P3b 事件相关的潜在调制索引注意力转移。当左视觉皮层感知到情绪消极的词语时，会引发 P3b，但当右半球感知到时，却无法触发这种与注意力相关的反应。结果表明，右半球在记录书面文字的负面情绪效价方面相对不敏感。
To assess cerebral functional asymmetry for accessing the meaning of emotional words, native English speakers were asked to make lexical decisions to emotional words, neutral words and nonwords briefly flashed in their left or right visual field, that is, perceived by their right or left visual cortex, respectively. Emotionally negative words had an overall probability of occurrence of 12.5% in each visual field and were expected to elicit a P3b event-related potential modulation indexing shifts of attention. Emotionally negative words elicited a P3b when perceived by the left visual cortex but failed to trigger such attention-related response when perceived by the right hemisphere. The results suggest relative insensitivity on the part of the right hemisphere in registering the negative emotional valence of written words.
