ABSTRACT
Objecttive The article analyzed how neurophysiological signals of adolescent's working memory(WM) change with increasing age.Methods:
We recorded ERP from 52 healthy subjects aged from 14 to 22 years old in three groups.Our experiment consisted of 4 subexperiments and had two types of working memory tasks spatial working memory and verbal working memory tasks,furthermore,every task included two levels of difficulty.Results:
①Reaction time was faster with increasing age,there was significant difference in accuracy of complicated tasks in different age groups with junior high school group significantly lower than others;②There was significant difference between junior high school group and college group in frontal P200 amplitude and its latency had no significant difference in the three groups;③Occipital P100 amplitude was descending when age was increasing and there had significant difference in latency between junior high school group and college group;④Occipital N160 amplitude was increasing with age and the latency was descending with age and there was significant difference between junior high school group and college group;⑤Average amplitude of parietal P300 was increasing with age and junior high school group's was significantly lower than the other two groups'.Conclusion:
Teenager's working memory changes unevenly with age.
