Studies suggest that reward and emotion are interdependent. However, there are discrepancies regarding the interaction between these variables. Some researchers speculate that the inconsistent findings may be due to different targets being used. Although reward and emotion both affect attention, it is not clear whether their impacts are independent. This study examined the impact of reward anticipation on emotion processing for different targets. A cue-target paradigm was used, and behavior and eye-tracking data were recorded in an emotion or sex recognition task under the conditions of reward and non-reward anticipation. The results showed that when the target was related to the emotional attribute of the stimulus, the reward promoted the processing target information, thereby generating reward-oriented attention. When the target was unrelated to the emotional attributes of the stimulus, the reward did not promote the processing target information, and at the same time, individuals had negative emotional biases toward the emotional faces. The results revealed that, in addition to affecting the attention to emotional faces independently, the target regulated the promotion of reward anticipation to emotional attention and attention bias toward negative stimuli.
研究表明，奖赏与情绪相互依存。然而，关于这些变量之间的相互作用存在差异。一些研究人员推测，结果不一致可能是由于使用了不同的目标。虽然奖赏和情绪都会影响注意力，但它们的影响是否独立尚不清楚。本研究考察了奖赏预期对不同目标情绪加工的影响。采用线索-目标范式，在奖赏预期和无奖赏预期条件下，记录情绪或性别识别任务中的行为和眼动数据。结果表明，当目标与刺激的情绪属性相关时，奖赏促进了目标信息的加工，从而产生了以奖赏为导向的注意力。当目标与刺激的情绪属性无关时，奖赏并未促进目标信息的加工，同时，个体对情绪面孔存在负性情绪偏向。结果显示，目标除了独立影响对情绪面孔的注意力外，还调节了奖赏预期对情绪注意力的促进作用以及对负性刺激的注意力偏向。
