The Comparative Study Of Recognition Between The Aged And The Young

Memory plays important roles in daily life of human beings.Memory is the process of coding,storing and extracting perceived information.Explicit memory has always been one of the significant topics in memory study,and recognition is the typical testing method of explicit memory.The researches of recognition memory in the past days are mostly concerned about the influence of data,word frequency,time interval and language differences.The aged group is involved in the current researches,but researches are rarely seen related to its comparison with the youth group.Most memory studies are done within the channels,rather than done between the channels.Based on this,the present study adopts the same study model(the continuous recognition model),controlled the time intervals and channels of presenting stimuli,and correspondingly record the recognition situations of high and low frequency words by the youth group and the aged group.Study One is the recognition of both frequencies words by the youth group;Study Two is the recognition of both frequencies words by the aged group.Firstly the two studies are analyzed based on different word frequency,and then it probes into the mediating effect of word frequency on the youth group(Study One)and that on the aged people(Study Two),separately.Also,it compares the recognition differences between different age groups in low frequency word situation,and further discusses the factors and relative mechanisms that influence explicit memory recognition.Research findings are as follows:(1)The time interval has effects on recognition of both the youth and aged groups.(2)The modality has more effects on recognition of the aged group than that of the youth group.(3)The word frequency type only has regulating effects on the aged group.(4)There are differences of explicit memory among both age groups.
