奖励协会是已知的形状大脑的视觉刺激的处理，但相对较少知道奖励协会如何影响听觉刺激的处理。在这里，我们利用高时间分辨率的脑电图（EEG）和事件相关电位（ERPs）来研究听觉古怪任务中低和高幅度刺激-奖励关联的影响。我们将快速，正确地检测某些听觉目标刺激与较大的金钱奖励，以及其他目标与较小的奖励相关联。我们发现，更高的奖励目标刺激，更快的行为检测这些刺激相比，低奖励刺激的注意力处理增强。在神经方面，更高的奖赏关联增强了听觉目标的早期感觉处理。与较高幅度的奖励相关的目标有较高的幅度N1和失配负性（MMN）ERP组件比与较低幅度的奖励相关的目标。奖励不影响这些早期成分的潜伏期。较高的奖赏幅度也降低了长潜伏期P3成分的潜伏期，增加了长潜伏期P3成分的振幅，这表明奖赏也可以增强听觉目标刺激的最终加工阶段。这些结果提供了洞察听觉刺激的感觉和注意力的神经处理是如何调制的刺激奖励协会和这些协会的幅度，与较低幅度的奖励协会相比，更高幅度的奖励协会产生增强的听觉处理。
Reward associations are known to shape the brain’s processing of visual stimuli, but relatively less is known about how reward associations impact the processing of auditory stimuli. Here, we leveraged the high-temporal resolution of electroencephalography (EEG) and event-related potentials (ERPs) to investigate the influence of low- and high-magnitude stimulus-reward associations in an auditory oddball task. We associated fast, correct detection of certain auditory target stimuli with larger monetary rewards, and other targets with smaller rewards. We found enhanced attentional processing of the more highly rewarded target stimuli, as evidenced by faster behavioral detection of those stimuli compared to lower-rewarded stimuli. Neurally, higher reward associations enhanced the early sensory processing of auditory targets. Targets associated with higher magnitude rewards had higher amplitude N1 and mismatch negativity (MMN) ERP components than targets associated with lower magnitude rewards. Reward did not impact the latency of these early components. Higher reward magnitude also decreased the latency and increased the amplitude of the longer-latency P3 component, suggesting reward can also enhance the final processing stages of auditory target stimuli. These results provide insight into how the sensory and attentional neural processing of auditory stimuli is modulated by stimulus-reward associations and the magnitude of those associations, with higher magnitude reward associations yielding enhanced auditory processing compared to lower magnitude reward associations.
