Time-series Memory Of Event References: The Effects Of Emotions

Temporal order memory,which constructs one's knowledge of sequential stimulus and event-time traits,is a memory that organizes and stores two or more different events' cognition in order.Due to its intimate relationship to daily life,temporal order memory has always been the research focus.Under the ‘study and test 'paradigm and with study materials including emotional words,emotional pictures and emotional videos,this study integrated behavioral experiment and ERP study to explore the sequential memory referring to important events(interrupted video).Study 1 adopted 3*3*2 experiment design,with three independent variables including pictures' emotional valence,interrupted videos' emotional valence and interval as well as four dependent variables including accuracy rate and RT of pictures' temporal order judgment,the accuracy rate of judging whether the pictures have been presented,and two ratings of how confident they were when judging.The result shows 1)scores of temporal order memory of neural pictures was higher than in other situations;2)positive pictures were more likely to process sequential source based on the interrupted video;3)under no-interrupted video situation,the scores of temporal order memory in neural pictures higher than in other situation.Study 2 adopted 3*3*2 experiment design,with three independent variables including words' emotional valence,interrupted videos' emotional valence and interval,as well as four dependent variables including accuracy rate and RT of words' temporal order judgment,the accuracy rate of judging whether the words had been presented,and two ratings of how confident they were when judging.The result shows 1)the scores of temporal order memory of negative words in negative video was better than in other situations;2)under the neural words,scores of temporal order memory in negative video was better than in other situations 3)negative words were more likely to process sequential source based on the interrupted video;4)under no-interrupted video situation,the temporal order memory in neural words performed better than in others;5)under interrupted video situation,the scores of temporal order memory in negative words higher than in othersStudy 3 within single factor,chose the emotional valence of pictures as dependent variable,while accuracy rate,RT of pictures' temporal order judgment and Dm Effect were chosen as independent variables.The result showed 1)the neurophysiologic base of temporal order memory in negative picture was contributed in frontal lobe,which wasactivated larger than that activated by neural pictures in the middle of area centralis 3)it was under no-interrupted video situation,the neurophysiologic base of temporal order memory in both negative picture and central picture was contributed in frontal area and area centralis.Picture item memory task was processed with consciousness,whereas the temporal order memory task in pictures and words were processed automatically and separately.From 300 ms to 400 ms,Dm Effect was separated saliently,which was the physiologic evidence of automatic process in temporal order memory in pictures.Whether the memory material were pictures or words,both item memory and temporal memory followed the rule of ‘ taking turns' to occupy cognitive resource.
