Research on individual differences in face and object processing has shown that difficult tasks used to measure performance accuracy capture a differentiated ability structure with separable factors within and across stimulus domains. In contrast, when easy tasks, designed to capture performance speed, are used, there is solely a unitary, domain-general ability factor, given that the methods of measurement (task paradigms) are equivalent across content domains. The proposed project aims to reconfirm the dichotomy of accuracy and speed related abilities with a direct test (Objective 1 and 2). More importantly, the project intends to elucidate neurocognitive mechanisms underlying these abilities by applying sophisticated state of the art tools of analysis to event-related brain potentials (ERPs). Objective 3 will consider mean performance and average ERP parameters of each participant. An additional Objective 4 will examine the variability of performance and ERP measures within participants and the relations of the prestimulus brain state to both average ERP and trial-to-trial ERP variability.

对面孔和物体处理的个体差异的研究表明，用于测量表现准确性的困难任务捕获了具有可分离因素的差异化能力结构。相比之下，当简单的任务，旨在捕捉性能速度，使用，只有一个单一的，域一般的能力因素，鉴于测量方法（任务范例）是等效的跨内容域。该项目旨在通过直接测试（目标1和2）重新确认准确性和速度相关能力的二分法。更重要的是，该项目旨在通过将先进的分析工具应用于事件相关脑电位（ERP）来阐明这些能力背后的神经认知机制。目标3将考虑每个参与者的平均表现和平均ERP参数。另一个目标4将检查参与者的表现和ERP测量的变异性，以及刺激前大脑状态与平均ERP和试验间ERP变异性的关系。
