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.

本研究旨在测试在进行基于 P300 的犯罪知识测试 (GKT) 之前刷新模拟犯罪细节的记忆是否会提高实验室环境中 GKT 的准确性。 P300 幅度被用作因变量，而情境依赖性记忆效应（中枢记忆与外周记忆）和 GKT 给药周期（模拟犯罪后一个月与一年）被作为自变量进行操作。模拟犯罪涉及进入一个房间并从五个办公桌抽屉（中央记忆）之一中偷走一枚戒指。戒指旁边有一滴信纸（外围存储器）。这两项在模拟犯罪发生后大约一个月或一年的 GKT 中被用作关键项目。在 GKT 之前，记忆恢复 (RM) 组观看了描绘他们实施模拟犯罪的房间的录像带，而无 RM (NRM) 组的参与者则观看了描绘他们实施模拟犯罪的房间的相同长度的录像带。学院其他部分的场景。无论记忆操作和 GKT 给药时间间隔如何，这两个关键项目都会引起显着更大的 P300 振幅。这些结果表明，以 P300 作为因变量，GKT 的现场应用可能是可行的。
