Investigating the relationship between media multitasking and executive function within a military population

Area of Science:

• Cognitive Psychology
• Military Psychology
• Human-Computer Interaction

Background:

• Media multitasking is prevalent, with research often showing negative links to executive function.
• The cognitive demands of the modern military environment necessitate understanding these effects in service members.

Purpose of the Study:

• To investigate the association between media multitasking behaviors and executive function in a military population.
• To determine if self-regulation moderates the relationship between media multitasking and executive function in military personnel.

Main Methods:

• Assessed self-reported media multitasking behaviors.
• Utilized performance-based measures for executive function, including a task-switching paradigm.
• Examined self-regulation as a potential moderator.

Main Results:

• No significant overall relationship was found between media multitasking and executive function.
• Average media multitaskers outperformed heavy media multitaskers in task-switching.
• Self-regulation did not moderate the media multitasking-executive function relationship in this military sample.

Conclusions:

• The impact of media multitasking on executive function in military members is complex and differs from civilian findings.
• Specific patterns of media multitasking, rather than overall engagement, may be more relevant to cognitive performance in military contexts.
