抑郁症患者项目记忆与来源记忆的研究

Study on Item Memory and Source Memory in Depressive Patients

摘要: 目的：探讨抑郁症患者与正常人的项目记忆与来源记忆的差异。方法：运用E-Prime2.0设计实验程序，应用实验程序测试14例抑郁症患者和14例正常人的项目记忆和来源记忆。第一部分用于测试项目记忆，第二部分用于测试来源记忆。结果：与正常人的项目记忆与来源记忆成绩相比，抑郁症患者的项目记忆和来源记忆成绩均低于正常人，其差异显著。无论正常人或抑郁症患者，来源记忆成绩均低于项目记忆成绩，其差异显著。且项目记忆与来源记忆之间存在双分离现象。结论：抑郁症患者的项目记忆与来源记忆都受损较明显，实验组与对照组的项目记忆与来源记忆的成绩差异均有显著性。且项目记忆与来源记忆之间分别独立。

Abstract: Objective: To explore the difference of item memory and source memory between depressive patients and normal people. Method: E-Prime 2.0 was used to design the experimental program. Item memory and source memory were tested in 14 patients with depression and 14 normal subjects. The experimental procedure is divided into two parts. The first part is used to test item memory. In the learning stage, only 30 Chinese high-frequency words are required to be memorized (30 words are arranged randomly according to 10 red, yellow and blue), and 60 Chinese high-fre- quency words are presented randomly in the testing stage. The subjects need to determine whether each word has seen and keystroke response before. The second part is used to test source memory. The subjects were asked to recall the color of each word (red, yellow and blue) and to respond to the keys. Record two phases of ACC. Result: Compared with the performance of item memory and source memory in normal people, the performance of item memory and source memory in depression patients was lower than that in normal people, and the difference was significant. Source memory scores were lower than item memory scores in both normal people and depressive patients, and the difference was significant. There is a double separation between item memory and source memory. Conclusion: Item memory and source memory were impaired significantly in depression patients. There were significant differences in the performance of item memory and source memory between the experimental group and the control group. Item memory and source memory are independent.
