本研究采用奖励和罚款两种方式考察了情绪效价对刺激前负性（SPN）的影响。在奖励、惩罚、组合和控制条件下进行时间估计任务。在奖励条件下，参与者因正确的反应而获得奖励，在惩罚条件下，参与者因错误的估计而被罚款。在组合条件下，正确的反应得到奖励，而不正确的反应受到惩罚。在控制条件下，既不使用奖励也不使用罚款。结果表明，条件x半球的显着相互作用。在奖励条件下，左半球的SPN增加。对于惩罚效应，虽然它唤起了右半球的优势，但在右半球没有明显的条件差异。这些结果表明，SPN受到积极情绪的影响：左半球的激活可能代表一种伴随金钱收益的愉快情绪。
This study examined the effects of emotional valence on stimulus-preceding negativity (SPN) using reward and fine. A time estimation task under reward, punishment, combined, and control conditions was performed. Participants were rewarded for accurate responses in the reward condition, and were fined for incorrect estimations in the punishment condition. in the combined condition, correct responses were rewarded and incorrect responses were fined. In the control condition, neither a reward nor fine was used. Results showed a significant interaction of condition x hemisphere. The SPN at the left hemisphere was increased in the reward condition. For the punishment effect, although it evoked right hemisphere dominance, no conditional difference was apparent at the right hemisphere. These results suggest that the SPN is affected by positive emotion: The left hemisphere activation might represent a pleasant emotion accompanying monetary gain.
