Attention is becoming more brittle
Recent reporting outlines how many people find sustained focus harder than before, and researchers link that change to a world of increased distraction. (abc.net.au) The coverage highlights the importance of designing entry routines that create a single visible prompt, an immediate action, and a clear model to capture attention quickly. (abc.net.au) That approach is being recommended as a response to broader shifts in how attention functions. (abc.net.au)
People are switching away from a screen task after about 47 seconds on average, down from roughly two and a half minutes in 2003 and 2004. (abc.net.au) Anna Levy reported for ABC on April 15, 2026 that psychologists increasingly link that drop to a daily environment packed with notifications from phones, computers and watches. Gloria Mark, a University of California, Irvine professor who has studied attention for more than two decades, has tracked the same decline in workplace screen behavior. (abc.net.au) (universityofcalifornia.edu) Attention is the brain’s system for deciding what gets priority, and one influential model says it relies on three networks: alerting, orienting and executive control. Michael Posner and Steven Petersen laid out that framework in a 1990 paper that still shapes how researchers explain focus and distraction. (abc.net.au) (annualreviews.org) The alerting network keeps people ready for new stimuli, the orienting network points attention toward a sight or sound, and executive control helps choose one task over competing demands. That last system is the one doing the traffic-control work when a message, email or headline interrupts reading, writing or study. (abc.net.au) Researchers do not say digital technology is the only cause of weaker focus, but they do say constant switching is stressful and measurable. The American Psychological Association said in a 2023 interview with Mark that internet-connected devices have made shrinking attention spans easier to observe over the past two decades. (apa.org) That shift has consequences beyond productivity. ABC’s report said some experts worry a population that struggles to sustain focus is more exposed to misinformation and disinformation because distraction makes careful evaluation harder. (abc.net.au) (pubmed.ncbi.nlm.nih.gov) Newer evidence has started to test cause, not just correlation. A randomized controlled trial published in PNAS Nexus on February 18, 2025 found that blocking mobile internet on smartphones for two weeks improved sustained attention, and 91 percent of participants improved on at least one outcome, including attention, mental health or well-being. (academic.oup.com) The same study let participants keep calls, texts and desktop internet, isolating the effect of always-on mobile access rather than removing technology altogether. The authors said the gains were partly explained by spending more time socializing in person, exercising and being in nature. (academic.oup.com) ABC’s piece points to a simpler response than trying to rebuild old habits by force: make the first seconds of a task easier to enter. The recommendation is to create an entry routine with one visible prompt, one immediate action and a clear model so attention locks onto the task before distractions do. (abc.net.au) That advice treats attention less like a fixed trait and more like a fragile state that can be shaped by environment. In a world where the next interruption is always one vibration away, the opening move now carries more weight than it used to. (abc.net.au)
