【摘要】 错误记忆是指个体把从未出现过的事件认为是发生过,或是对实际发生过的事情的记忆与现实存在差异的现象。心境一致性记忆是指正性心境下的个体对正性材料有更好的记忆,负性心境下的个体对负性材料有更好的记忆。心境一致性错误记忆是指个体对同自身心境效价相同的材料会出现更多的错误再认。国内外常以抑郁症患者为被试,探讨心境一致性对错误记忆的影响,有研究发现心境一致性错误记忆现象的出现受到词语性质和材料语境效价的影响。抑郁与自杀意念有紧密的联系,本研究探讨了自杀意念者的心境一致性错误记忆现象以及词语性质和材料语境效价的影响。本研究包括三个实验。实验使用经典的DRM范式。实验一研究当词语性质变化时自杀意念被试是否出现心境一致性错误记忆现象,采用2(组别)×4(词语性质)×3(词语类别)的三因素混合设计;实验二研究材料语境效价变化时自杀意念被试是否出现心境一致性错误记忆现象,采用2(组别)×3(材料语境效价)×3(词语类别)的三因素混合设计;实验三研究当词语性质和材料语境效价同时变化时自杀意念被试是否出现心境一致性错误记忆现象,采用2(组别)×4(词语性质)×3(材料语境效价)×3(词组类别)的四因素混合设计。结果发现:1.自杀意念者在负性词语和抑郁性词语中出现了心境一致性错误记忆现象。2.当来自不同语境中的中性名词再次出现在中性语境时,自杀意念者没有出现心境一致性错误记忆现象。3.当词语性质和材料语境效价同时发生变化时,自杀意念者在负性词语和抑郁相关性词语中都没有出现心境一致性错误记忆现象;新语境为负性时,自杀意念者出现了心境一致性错误记忆现象,负性的新语境促进了自杀意念者的心境一致性错误记忆现象的出现;旧语境为负性时,自杀意念者没有出现心境一致性错误记忆现象,负性的旧语境抑制了自杀意念者的错误记忆现象的出现。更多还原

【Abstract】 False memory refers to the phenomenon that an individual thinks that an event that never happened has happened,or that the memory of an event that actually happened is different from the reality.Mood congruent memory means that individuals in positive mood have better memory of positive materials,while individuals in negative mood have better memory of negative materials.Mood congruence false memory refers to the fact that individuals will have more false recognitions of materials with the same mood valence.Depression patients are often taken as subjects to explore the effect of mood congruence on false memory.Some studies have found that the appearance of mood congruence false memory is affected by word nature and the valence of the context.There is a close relationship between depression and suicidal ideation.This study explored the mood congruence false memory of suicidal ideators and the effects of word nature and the valence of the context.This study included three experiments.The experiment uses the classic DRM paradigm.Experiment 1 was conducted to investigate whether the subjects with suicidal ideation had mood congruent false memory when the nature of words changed,uses 2(group)× 4(word nature)× 3(word category)three-factor mixed design of unrelated items.In Experiment 2,participants with suicidal ideation were asked whether they had mood congruent false memory when the context potency changed,uses 2(group)×3(the valence of the context)×3(word category)three-factor mixed design of unrelated items.Experiment 3 was conducted to investigate whether mood congruent false memory occurred in subjects with suicidal ideation when the nature of words and contextual valence of materials changed at the same time,uses2(group)× 4(word nature)×3(the valence of the context)× 3(word category)four factor mixed design.The results showed that:1.The suicidal ideators had mood congruence false memory in negative words and depressive words.2.When neutral nouns from different contexts reappear in the neutral context,the suicidal ideators did not have mood consistency false memory.3.When the nature of words and the contextual valence of materials changed at the same time,there was no mood congruent false memory in negative words and depression related words;When the new context is negative,the suicidal ideants have mood consistency false memory,and the negative new context promotes the occurrence of mood consistency false memory;When the old context is negative,the suicidal ideator does not have mood consistency false memory phenomenon,and the negative old context inhibits the occurrence of suicidal ideator’s false memory phenomenon.更多还原
