The Effects Of Task Regularity、Regularity Known And Cognitive Load On Prospective Memory Of Junior High School Students

Prospective memory refers to the memory of carrying out an action in the future.The purpose of this study was to explore the effects of task regularity,regularity known and cognitive load on the prospective memory of junior high school students.In order to fully understand the effects of task regularity,regularity known and cognitive load on the event-based and the time-based prospective memory of Junior high school students,two experiments were designed.Dual-task paradigm was designed in both experiments.In Experiment 1,the mixed experimental design of 2(task regularity: regularity and irregularity)× 2(regularity known: known and unknown)× 2(cognitive load: low load and high load)was designed to study the event-based prospective memory of Junior high school students.Task regularity was within-subjects design,regularity known and cognitive load were between-subjects design.The ongoing task was a letter Nback task,and it was prospective memory task to perform an appropriate response when a specific letter was encountered.In Experiment 2,a 2(task regularity: regularity and irregularity)× 2(cognitive load: low load and high load)mixed experimental design was designed to study the time-based prospective memory of Junior high school students.Task regularity was within-subjects design,and cognitive load was between-subjects design.The ongoing task was a letter N-back task,and it was prospective memory task to perform an appropriate response at a specific time.The results show that:(1)There is an interaction between task regularity and regularity known on event-based prospective memory of junior high school students.In the irregular prospective memory task,there is no significant difference between the regularity known score and the regularity unknown score;in the regular prospective memory task,the regularity known score is better than the regularity unknown score.(2)There is an interaction between task regularity and cognitive load on event-based prospective memory of junior high school students.Under low cognitive load and high cognitive load,regular prospective memory task scores are better than irregular prospective memory task scores,but the difference between regular and irregular prospective memory tasks is greater under high cognitive load.(3)Task regularity promotes the automated processing of event-based and time-based prospective memory of junior high school students.(4)Cognitive load affects event-based and time-based prospective memory of junior high school students.The higher the cognitive load,the worse the prospective memory.
