A University of California psychologist warns that rising use of digital technologies, including AI chatbots, is dramatically reducing attention spans and increasing stress levels.
- Attention spans dropped from 2.5 minutes in 2003 to under 1 minute by 2020.
- Rapid attention switching correlates with heightened stress and lower productivity.
- Social media lawsuits underscore mental health concerns, especially for children.
What happened
Gloria Mark, a psychologist from the University of California, Irvine, has studied how digital device usage affects human attention for over three decades. Her research found that average attention spans decreased from about two and a half minutes in 2003 to only 47 seconds by 2020, demonstrating a clear downward trend in our ability to maintain focus.
At SXSW London, Mark discussed how frequent switching between digital tasks generates stress, as confirmed by correlations with heart rate increases during her studies. She emphasized that constant distraction compromises both task performance and emotional well-being across all age groups, raising concerns about the growing infiltration of AI chatbots and social media in everyday routines.
Why it matters
This shrinking attention span and heightened stress impact cognitive function and productivity, posing broader societal challenges as more people rely on digital tools for work, education, and social interaction. The rapid uptake of AI chatbots adds a new dimension to this problem by potentially accelerating cognitive overload through constant interaction and information processing demands.
Legal actions against major social media companies like Meta and YouTube reflect serious worries about digital addiction among children and teenagers. Lawsuits claim platforms are designed to be addictive and detrimental to mental health, with significant financial claims from affected school districts and individuals, highlighting the urgency for policy and innovation addressing these harms.
What to watch next
Future research, including long-term studies underway in Australia following its new under-16s social media ban, aims to clarify the complex effects digital and AI technologies have on developing brains and mental health. These studies may help define safer usage guidelines and regulatory frameworks.
As AI chatbots and digital tools continue to evolve and embed themselves deeper into daily routines, stakeholders should monitor trends in attention metrics, stress levels, and behavioral changes closely. There is also a need to balance technology’s benefits for connection and learning against potential risks to cognitive control and well-being.
