Emotional Information Of The Directional Forgotten Effect

Although we often definite forgetting as unable to extract the information wewant to remember. However, intentioned forget harmful or irrelevant informationis also an important function of memory. In recent years, many discussions focuson the degree to which we choose to forget the specific information, whenthestimulus happened to beemotional stimuli,this controversyis morewidely.Directed forgetting as one of the most effective paradigms to do intentionalforgetting researches was used in numerous areas. However, after years ofexperimental research taking emotional information as material, there are stilldifferent opinions about the mechanism of directed forgetting. Different materialand methods have different directed forgetting effects of emotional memories. Andmost of the experimental studies have focused on item memory and ignored thestudy on source memory accuracy. So it is necessary to design experiments tofurther discuss the mechanism of the directed forgetting of emotional information,with its effect on both item memory and source memory.This paper designs three interrelated research. Research A investigated theinfluence of dialectical thinking to directed forgetting of emotional informationand source memory. There are three independent experimental studies. The firststudy discussed directed forgetting and source memory of three different kinds ofemotional materials. The second study discussed after positive dialectical thinkingprocessing of negative and neutral words, how memory changes. The third studydiscussed influence to memory after negative dialectical thinking process ofpositive and neutral words. And finally analysis the mechanism of directedforgetting and the influence of dialectical thinking to memorize emotional wordscombined with results of all three studies. The results show that the processing ofdialectical thinking can change nature and strength for emotional words whichrepresented events. It also can increase accuracy of coding, increase mentalprocessing resources, promote memory reconstruction of emotional information.Research Two manipulated coding accuracy of source memory directly, so asto discuss influence source memory coding accuracy to directed forgetting andsource memory. Results showed that, increasing present time of source memory reduced cognitive resources occupied by item memory. Exquisite coding ofsource memory, there are still a directed forgetting effect. That means the codingaccuracy increases can not change the directed forgetting effect, forgetinstruction still play a role in the extraction phase. This is one of the mechanismsof directed forgetting.Research Three investigated the influence of changing item memory codingaccuracy to directed forgetting and source memory of emotional information.Results showed that participants used more time to judge word color.That compared with the simple directed forgetting paradigm shows add colorjudgments to words, increases the processing time of this stage, deepenedthe subjects processing on item memory. Exquisite item memory processing,weakened the directed forgetting effect, but does not change the instruction isstill in play, directed forgetting paradigm still effective.Through the above three research conclusions can be drawn as follows:(1) The dialectical thinking can change the nature and intensity of emotion, toimprove the safety of emotional information.(2) Forget task instruction still has an inhibitory effect on the extraction stage,which is one of the mechanisms of directed forgetting.(3) Effects of dialectical thinking on word memory, can promote thesignificance construction of the emotional events.(4) Positive information has a memory advantage effect...
