The Effects Of Learning Background And Retrieval Methods On Declarative Memory Updating

As a basic mental process,memory is closely related to other mental activities.The traditional memory theory is that once memories are consolidated,they are fixed and cannot be changed.With the study of memory process,it is found that there is a process of reconsolidation in memory besides consolidation.In recent years,the reconsolidation of memory has become a hot topic.Whether encoding memory material in a certain learning background will affect the retrieval method of declarative memory reconsolidation and whether it can open memory reconsolidation stage is not clear,Therefore this study investigates the impact of retrieval methods in learning background on declarative memory reconsolidation by setting a certain learning background in the acquisition stage and intervention stage.In this study,learning background materials and nonsense syllables were used as learning materials in Forcato et al.,and two methods of free recall and cue recall were adopted during measurement.The research is divided into two parts.Experiment 1 is to explore the effective retrieval method of declarative memory reconsolidation coding in the same learning background in the acquisition stage and intervention stage.Experiment 2 further explored the effective retrieval methods of entering declarative memory and reconsolidation in different learning background in the acquisition stage and intervention stage.The experimental results are as follows:（1）In Study 1,from the experimental results,the cue retrieval indexes of the four groups showed that the retrieval method adopted in the same learning background in the acquisition stage and intervention stage did not make each group enter reconsolidation successfully;In the comparison of error types,in the blank error type,the accuracy of learning background retrieval group is higher than that of other retrieval groups.（2）In Study 2,the experimental results show that in the cue recall index,cue retrieval can successfully enter the memory reconsolidation stage of declarative memory.In terms of error types,there were significant differences in the intrusion errors of the cue retrieval group.The contents of list 1 were invaded by a large number of contents of list 2,which proved once again that cue retrieval successfully entered the stage of reconsolidation of declarative memory.The findings revealed that cue retrieval made declarative memory successfully enter the reconsolidation stage.The results show that memory reconsolidation occurs in declarative memory,and the process of memory reconsolidation can effectively update the original memory by receiving new information.Experiments show that not all retrieval methods can initiate declarative memory reconsolidation,and learning background in acquisition and intervention stages may also affect the effect of declarative memory reconsolidation.This research can be further explored.
