Social Media Scrolling Alters Time Perception, LMU Research Finds

Researchers at Ludwig-Maximilians-Universität München (LMU) have investigated why time seems to fly by when scrolling through social media. Cognitive psychologist Professor Zhuanghua Shi's work focuses on how the brain constructs our sense of time and the impact of continuous digital stimuli.

The study found that actively scrolling through social media made time feel shorter compared to viewing a static image. Participants estimated a 40-second period as approximately 27 seconds when scrolling, while a static image made it feel like 30 seconds. Passively watching moving content also shortened the perceived time compared to static content.

Neurocognitive methods, including EEG and eye-tracking, were used to analyze participants' brain activity and attention. The constant stream of content and active navigation in social media intensely capture attention, which is crucial for time perception. While scrolling can provide a sense of control, it simultaneously distorts the experience of time.

The effects of attentional capture persist even after stopping. This phenomenon, known as "attentional residue," means a part of the brain continues to search for new stimuli, potentially reinforcing the urge to return to the screen. This sustained digital exposure can also affect long-term memory.

However, researchers emphasize that this state is not permanent. Approximately 20 minutes of focused activity without digital distractions, such as a walk or conversation, can help restore normal attention and time perception.
