保存时距对短期记忆之记忆量的影响

目的:通过对大学生短期记忆之记忆量的测定,探讨保存时距对短期记忆的记忆量的影响。方法:以学习材料(每组20个汉字,共5组)、电脑、大学生为研究对象(42名北大医学部2003级学员参加实验),实验中包括1 s立即回忆,2 s立即回忆,1 s延迟回忆,2 s延迟回忆4种不同的测验方式,并随机分配给42名参加实验的学员进行测量。结果:进行F检验作保存时距与短期记忆保留量之间的分析得到,在短期记忆中,时距的长短对记忆量的影响很大,而在长期记忆中,时距的长短对记忆量的影响不大;当保存时距较长时,延迟作用比较明显,而当保存时距较短时,延迟作用并不明显。

Effects of Time Slice to Short - Term Memory of Undergraduate

Objective: From measuring the short-term memory's capacity of undergraduate,we can probe into the effect of time slice to short-term memory of undergraduate.Methods:Studying material(5 groups, each group includes 20 Chinese characters),computer,and undergraduates(42 college students from medical department of peking university) are necessary in the experiment.The experiment is divided into 4 parts,including 1-secondimmediate memory,2-second immediate memory,1-second lingering memory,and 2-second lingering memory,and each part is stochasticallydistributed among the 42 undergraduates to make a measure.Results: Using F proof to analyze the data from the measure between preservative time slice and short-term memory's capacity,we can see that in the short-term memory,the effect of time slice is great,but in the long-term memory,the effect of time slice is not apparent;and when the preservative time slice is long,the effect of linger is great,while it is short,the effect is not apparent.
