Event-related potentials from symmetrical points of the left and right frontal and occipital cortex were recorded while subjects experienced positive and negative emotions. The emotions were elicited by either missing or hitting a target with a photoelectric gun. Twenty three right-handers (10 males and 13 females) were tested. Each subject took part in two sessions. In the first session the subjects were informed about their performance (hit or miss) after each shot. In the second, control session, no feedback was given. The amplitudes of P180 potential registered from the occipital cortex were higher in the right than in the left cerebral hemisphere, irrespectively of subjects' performance (i.e. a miss or a hit). No such tendency was observed in potentials registered from the frontal cortex. These regularities emerged only in the feedback situation, i.e. when subjects were informed about their performance, although higher ERPs were registered for hits than for misses. The results support the hypothesis that the posterior region of the right hemisphere is more engaged than the left one in experiencing emotions, irrespectively of their sign.
在受试者体验积极和消极情绪时，记录来自左右额叶和枕叶皮质对称点的事件相关电位。情绪通过用光电枪未击中或击中目标来诱发。测试了23名右利手（10名男性和13名女性）。每个受试者参加两个阶段的测试。在第一阶段，每次射击后告知受试者他们的表现（击中或未击中）。在第二个对照阶段，不给予反馈。无论受试者的表现（即未击中或击中）如何，从枕叶皮质记录的P180电位的振幅在右半球高于左半球。在额叶皮质记录的电位中未观察到这种趋势。这些规律仅在反馈情况下出现，即当受试者被告知他们的表现时，尽管击中时记录的事件相关电位高于未击中时。结果支持这样的假设，即无论情绪的正负，右半球后部区域比左半球更多地参与情绪体验。
