Have you ever found yourself scrolling through social media while watching a show, only to realize you missed key details? This is a common experience in today’s world, where digital multitasking has become second nature. But how does juggling multiple devices affect memory and concentration? (Harvard Health Publishing, 2020).

The challenge of divided attention
The rise of digital media has made multitasking more common, but research suggests that it may present cognitive difficulties. Media multitasking—using multiple digital devices or platforms simultaneously—has been linked to increased impulsivity and difficulty filtering distractions. When attention is constantly shifting, the brain struggles to prioritize relevant information, making it harder to focus on a single task (Uncapher et al., 2016).
The connection between memory and multitasking
Heavy media multitaskers could experience reduced working memory performance, meaning they may retain less information in the short term. Since working memory plays a role in storing and processing data, frequent digital distractions could contribute to forgetting key details or needing more time to recall information. Studies indicate that heavy media multitaskers tend to hold less precise representations of goal-relevant information, which potentially affect long-term memory as well (Harvard Health Publishing, 2020; Uncapher et al., 2016).
The impact on focus and attention
Notifications, alerts, and pop-ups constantly demand attention, leading to frequent interruptions. Each time focus is diverted, the brain needs time to refocus on the original task, which can slow down productivity. This continuous cycle of distraction may contribute to difficulty maintaining prolonged attention and completing complex tasks (Harvard Health Publishing, 2020; Uncapher et al., 2016).
Balancing media use for a greater concentration
With digital distractions everywhere, making deliberate choices about media use may help maintain concentration. Studies suggest that self-reported impulsivity correlates with media multitasking behavior, indicating that individuals who engage in frequent multitasking may benefit from strategies that encourage controlled attention. Since interruptions can disrupt working memory and lead to reduced long-term recall, minimizing unnecessary digital engagement may support cognitive function. Understanding how multitasking affects attention and memory could encourage greater media habits that align with our cognitive health (Uncapher et al., 2016).
