目的:考察大学生对正性、负性和中性词在内隐记忆和外显记忆上的差异。方法:分别使用真假词判断任务和学习-再认范式考察被试对不同情绪词的内隐和外显记忆。结果:在内隐记忆中,大学生对不同情绪词的反应时存在显著差异(F=6.360,P<0.05)。进一步分析发现,对积极词的反应时(573.0±57.9ms)和消极词的反应时(650.3±109.12ms)显著短于对中性词的反应时(671.8±101.0ms),但积极词与消极词的反应时之间差异不显著。在外显记忆中,大学生对不同情绪词的正确率和反应时均存在显著差异(F=7.353,15.000,P<0.05)。进一步分析发现,被试对积极词记忆的正确率(67.0%±17.9%)明显高于消极词(46.3%±15.9%)和中性词(50.3%±20.4%),但中性词与消极词的正确率差异不显著。积极词(688.2±129.3 ms)和消极词的反应时(814.5±140.3ms)均低于中性词的反应时(951.8±182.0ms),且积极词的反应时明显低于消极词的反应时。结论:刺激本身所具有的情绪信息会影响个体的记忆,个体对不同情绪词的内隐记忆与外显记忆存在差异。
Objective: To investigate the difference of implicit memory and explicit memory between positive, negative and neutral words in college students. Methods: To use the true and false words to judge the task and study respectively - to re-recognize the subjects to examine the implicit and explicit memory of different emotion words. Results: In implicit memory, there were significant differences in college students’ responses to different emotion words (F = 6.360, P <0.05). Further analysis showed that the responses to positive words (573.0 ± 57.9ms) and negative words (650.3 ± 109.12ms) were significantly shorter than those for negative words (671.8 ± 101.0ms), but positive words and negative words The difference in word response time was not significant. In explicit memory, there was a significant difference (F = 7.353, 15.000, P <0.05) in the correct rate and response rate of college students to different emotion words. Further analysis showed that the correct rate of positive words memory (67.0% ± 17.9%) was significantly higher than negative words (46.3% ± 15.9%) and neutral words (50.3% ± 20.4%), but the neutral words were negative The correctness of the word difference is not significant. The positive words (688.2 ± 129.3 ms) and passive words (814.5 ± 140.3 ms) were lower than those of neutral words (951.8 ± 182.0 ms), and the response time of positive words was significantly lower than that of negative words . Conclusion: The emotional information of the stimulus itself affects the individual memory. Individuals have different implicit and explicit memory of different emotional words.
