In a between design study of 15 participants(5 males,10 females),long-term memory of symbols were measured under different time-limited conditions to discover the effects of time limitation.All participants were college students and currently enrolled in Psychology class.They were randomly assigned into three groups and were offered the same materials of symbolic information to memorize under different time condition(1 minute,2 minutes,and 3 minutes).A filler test was added into this study to verify that long-term memory of materials was formed.As a result,the findings suggest the hypothesis that the more time limitation was given,the less accuracy of long-term memory of materiel they would have:The first group scored significantly lower than the second and the third group on the recall test,F(2,42) = 6.60,p <.05.However,the second and the third group were not significantly different,F(2,42) = 6.60,p >.05.
