The world population is rapidly aging, bringing together the necessity to better understand the advancing age. This characterization may be used to aid early diagnosis and to guide individually-tailored interventions. While some event-related potential (ERP) components, such as the P300 and late positive complex (LPC), have been associated with fluid intelligence (Gf) in young population; little is known whether these associations hold for older people. Therefore, the main goal of this study was to assess whether these ERP components are associated with Gf in the elderly. Fifty-seven older adults performed a continuous performance task (CPT) and a visual oddball paradigm while EEG was recorded. Participants were divided into two groups, according to their performance in the Raven’s Advanced Progressive Matrices test: high-performance (HP) and low-performance (LP). Results showed that the HP group, compared to the LP group, had higher LPC amplitudes in the CPT and shorter P300 latencies in the oddball task, highlighting the role of ERP components as a potential electrophysiological proxy of Gf abilities in the elderly.

世界人口正在迅速老龄化，因此有必要更好地了解老龄化问题。这种特征可用于帮助早期诊断和指导个性化的干预措施。虽然一些事件相关电位 (ERP) 成分，例如 P300 和晚期阳性复合体 (LPC)，已与年轻人的流体智力 (Gf) 相关；很少有人知道这些协会是否适用于老年人。因此，本研究的主要目标是评估这些 ERP 成分是否与老年人的 Gf 相关。57 名老年人在记录 EEG 的同时执行了连续表现任务 (CPT) 和视觉古怪范式。根据参与者在 Raven 的高级渐进矩阵测试中的表现，他们被分为两组：高性能 (HP) 和低性能 (LP)。结果表明，与 LP 组相比，HP 组在 CPT 中具有更高的 LPC 幅度和在古怪任务中更短的 P300 延迟，突出了 ERP 组件作为老年人 Gf 能力的潜在电生理代理的作用。
