Abstract:
Objective:To investigate the temporal dynamics of strategy monitoring during prospective memory testin individuals with varying degrees of media multitasking.Methods:Twenty heavy media multitaskers and twen-ty light media multitaskers were identified through the media use questionnaire.Using a dual-task paradigm and e-vent-related potential technique,the two groups' accuracy,response time,and the amplitudes of frontal positive components reflecting strategy monitoring were compared across the early,middle,and late stages of the prospective memory test.Results:Heavy media multitaskers exhibited significantly faster response times compared to light media multitaskers(P＜0.001),with no statistical difference in accuracy(P＞0.05).Moreover,the amplitude of frontal positive components in heavy media multitaskers was greater than that in light media multitaskers(P＜0.05)across all three stages,and the amplitude increased gradually with the passing of time in heavy media multi-taskers(P＜0.05).Conclusion:Heavy media multitaskers tend to allocate more cognitive resources to strategic mo-nitoring over time,while light media multitaskers maintain a relatively consistent level of strategic monitoring.
