我们之前的事件相关脑电位（ERP）结果表明，在选择性聆听过程中，通过将每个刺激与“注意痕迹”进行比较，选择相关刺激进行进一步处理，“注意痕迹”是相关刺激物理特征的神经元表征，可将它们与不相关刺激区分开来。这种比较过程反映在处理负性（PN）的早期部分，它对于相关刺激来说是最大且最长的（与轨迹完美匹配）。在本研究中，受试者有选择地聆听指定的音调刺激，这些刺激随机出现在不同音高的不相关音调中。块中相关刺激的概率是变化的。相关刺激出现的频率越低，引起的处理消极性就越小。结果支持选择性注意的注意痕迹理论，该理论提出，除了主动维持之外，痕迹还取决于相关刺激提供的感觉强化率。
Our previous event-related brain potential (ERP) results suggest that during selective listening, relevant stimuli are selected for further processing by comparing each stimulus to an "attentional trace," a neuronal representation of the physical features of the relevant stimuli that distinguish them from the irrelevant stimuli. This comparison process is reflected by the early component of the processing negativity (PN), which is largest and longest to the relevant stimuli (perfectly matching with the trace). In the present study, the subjects selectively listened to designated tone stimuli which randomly appeared among irrelevant tones of a different pitch. The probability of relevant stimuli in a block was varied. The processing negativity elicited by relevant stimuli was smaller the less frequent they were. The results support the attentional-trace theory of selective attention, which proposes that, in addition to active maintenance, the trace also depends on the rate of sensory reinforcement provided by the relevant stimuli.
