P3的刺激评估假说指出，P3 ERP成分（也称为P300）的潜伏期对延迟刺激处理的实验因素特别敏感，并且相对不受延迟反应选择和执行的变量的影响（例如，Duncan-Johnson和Kopell，1981）。因此，根据这一假设，P3潜伏期提供了一种手段，用于将产生明显刺激诱导反应时遇到的延迟分解为与刺激评估相关的部分和与反应产生相关的部分。
The stimulus-evaluation hypothesis of P3 states that the latency of the P3 ERP component (also termed P300) is specifically sensitive to experimental factors that delay stimulus processing and is relatively unaffected by variables that delay response selection and execution (eg, Duncan-Johnson and Kopell, 1981). Therefore, according to this hypothesis, P3 latency offers the means for decomposing delays encountered while producing overt stimulus-induced responses into the portion associated with stimulus evaluation and the portion associated with response production.
