Psychologist Warns AI and Digital Technology Are Shrinking Human Attention Spans
Gloria Mark, a psychologist at UC Irvine, presented research at SXSW London showing average adult attention spans have declined from 2.5 minutes in 2003 to just 47 seconds by 2020. Her decades of research using sensors and trackers in 'living laboratories' links frequent attention-switching to increased stress and reduced performance. The findings raise urgent questions about the additional cognitive impact of AI chatbots on top of already-diminished attention spans.
Gloria Mark, a psychologist at the University of California, Irvine, presented findings at SXSW London showing a dramatic decline in human attention spans over the past two decades of digital technology use. Her research tracked average focused attention time dropping from approximately 2.5 minutes in 2003 to 75 seconds in 2012, and further to just 47 seconds between 2014 and 2020. Using heart rate monitors alongside behavioral trackers, Mark found a direct correlation between frequent attention-switching and elevated stress levels, with negative effects on both performance and emotional well-being. The research comes amid growing legal pressure on social media companies, with Meta facing lawsuits from school districts and individuals alleging their platforms were designed to be addictive and harmful to children. Mark noted that evidence on social media's effects on children remains inconclusive despite widespread public debate, and expressed hope that large-scale longitudinal studies, such as those enabled by Australia's recent social media ban for under-16s, may provide clearer answers. Her concerns now extend to AI chatbots, which represent an even newer and more pervasive form of digital interaction layered on top of already-strained attention systems.
What's missing
The article does not detail the methodology or sample sizes of Mark's attention span studies, which are critical for evaluating the robustness of the declining-attention-span findings. Additionally, causality between technology use and shrinking attention spans has not been firmly established; correlation-based findings are sometimes overstated in popular coverage.
How coverage differed
MIT Technology Review, rated center, framed the story primarily through the lens of scientific concern and expert credibility, while also acknowledging nuance around inconclusive evidence on children. The framing at SXSW London, a tech-culture event, may have amplified alarm around AI specifically, given the conference context.

Widespread US Heat Wave Brings Dangerous Temperatures Across Multiple Regions
A significant heat wave is spreading across the central United States with heat index values forecast to exceed 110 degrees in parts of Texas and 100 degrees across multiple states including Missouri, Kansas, Iowa, Arkansas, and Tennessee. The National Weather Service warns that early-season heat waves pose greater risks for heat-related illness and could break daily temperature records across numerous states. The extreme heat is expected to impact more than 20 cities, with temperatures 10-20 degrees above normal in some regions, particularly the Upper Midwest and Great Lakes area.
Study Finds Noncognitive Skills Like Motivation and Curiosity Critical to Academic Success
Researchers at Queen Mary University of London conducted a major study showing that noncognitive skills such as motivation, curiosity, academic interest, and self-belief significantly influence how children translate their genetic potential into actual academic achievement. The research highlights that beyond innate ability, psychological and behavioral factors are essential determinants of educational outcomes. This finding suggests that interventions targeting motivation and attitude may be as important as traditional academic support in improving student performance.
NASA Announces Four-Person Crew for Artemis III Moon Mission
NASA has announced the crew for Artemis III, consisting of NASA astronauts Andre Douglas, Randy Bresnik, and Frank Rubio, along with ESA astronaut Luca Parmitano. The mission will test integrated operations between NASA's Orion spacecraft and commercial lunar landers from SpaceX and Blue Origin. This represents a significant step in NASA's plan to return humans to the Moon and establish sustainable lunar exploration capabilities.
