侧化准备电位（LRP）等心理生理学测量方法已被用于研究埃里克森侧卫任务中的信息加工。这些测量提供的数据符合连续流理论，即刺激评价的输出连续地提供给反应通道。Cohen et al.（1992）在连接主义模型中实现了这一理论，并表明其行为与人类受试者在侧卫任务中的行为相对应。我们在此报告了模型的修改和模拟lrp（基于模型响应单元的激活函数）在相同任务中与人类受试者的实际lrp相似程度的分析。在各种不同的实验条件和结果中，模拟和实际lrp之间存在明显的对应关系。这些观察结果加强了连接主义模型及其所依据的连续流理论的正确性。
Psychophysiological measures such as the lateralized readiness potential (LRP) have been used to study information processing in the Eriksen flankers task. The data provided by these measures are consistent with a continuous flow theory, which proposes that the output of stimulus evaluation is continuously available to the response channels. Cohen et al. (1992) realized this theory in a connectionist model and showed that its behavior corresponded to that of human subjects in the flankers task. We report here a modification of the model and an analysis of the degree to which simulated LRPs (based on the activation functions of the response units of the model) resemble the actual LRPs of human subjects in the same task. Across a variety of different experimental conditions and outcomes, there was a marked correspondence between the simulated and actual LRPs. These observations strengthen the propriety of the connectionist model and of the continuous flow theory on which it is based.
