项目摘要

The present study was designed to test whether refreshing memory of mock-crime details prior to administration of a P300-based guilty knowledge test (GKT) would enhance GKT accuracy in a laboratory setting. P300 amplitude was used as a dependent variable while context-dependency memory effect (central vs. peripheral memory) and periods of GKT administration (one month vs. one year after a mock-crime) were manipulated as independent variables. The mock-crime involved entering a room and stealing a ring from one of five desk drawers (central memory). Beside the ring there was a dip of stationery (peripheral memory). These two items were used as critical items in the GKT that was administered approximately one month or one year after the mock-crime. Prior to the GKT, the refreshing-memory (RM) group viewed a videotape that depicted the room in which they had committed the mock crime, while the participants in the no-RM (NRM) group viewed a videotape of the same length that depicted scenes from other parts of the college. Both the critical items elicited significantly larger P300 amplitudes regardless of the memory manipulation and gaps in time of the GKT administration. These results suggest that the field applications of the GKT may be feasible, with P300 as the dependent variable.

本研究旨在测试在管理基于P300的有罪知识测试（GKT）之前对模拟犯罪细节的刷新记忆是否会在实验室环境中提高GKT的精度。 p300振幅用作因变量，而上下文依赖性记忆效应（中心与外围存储器）和GKT给药的周期（一个月与模拟犯罪后的一年）被操纵为自变量。模拟犯罪涉及进入一个房间并从五个桌子抽屉之一（中央记忆）中窃取戒指。在戒指旁边有一小块文具（外围记忆）。这两个项目被用作GKT中的关键物品，大约在模拟犯罪后一个月或一年后管理。在GKT之前，刷新的内存（RM）小组查看了一部录像带，描绘了他们犯下模拟犯罪的房间，而No-RM（NRM）小组的参与者观看了与大学其他地区相同长度的录像带。这两个关键项目都引起了较大的P300振幅，而不管GKT给药时内的记忆操作和差距如何。这些结果表明，GKT的现场应用可能是可行的，P300是因变量。
