Studie kopplar daglig mental skärpa till ökad produktivitet

Forskare vid University of Toronto Scarborough har funnit att en känsla av mental skärpa under en dag kan öka produktiviteten med upp till 40 minuter. Studien, som publicerats i Science Advances, följde universitetsstudenter under 12 veckor och kopplade klarare tänkande till att sätta upp och nå större mål. Faktorer som sömn och arbetsbelastning påverkar dessa dagliga fluktuationer.

Ett team lett av Cendri Hutcherson, docent vid psykologiska institutionen vid University of Toronto Scarborough, undersökte hur dagliga förändringar i mental skärpa påverkar måluppfyllelse. Deltagarna genomförde dagliga kognitiva tester som mätte tankehastighet och noggrannhet, vid sidan av rapporter om sina mål, produktivitet, humör, sömn och arbetsbelastning. De dagar då studenterna kände sig skarpare än vanligt utförde de fler uppgifter och satte högre mål, särskilt när det gällde akademiskt arbete, oavsett egenskaper som uthållighet eller självkontroll. Hutcherson noterade: 'Alla har bra och dåliga dagar. Det vi fångar upp är vad som skiljer de bra dagarna från de dåliga.'

University of Notre Dame researchers report evidence that general intelligence is associated with how efficiently and flexibly brain networks coordinate across the whole connectome, rather than being localized to a single “smart” region. The findings, published in Nature Communications, are based on neuroimaging and cognitive data from 831 Human Connectome Project participants and an additional 145 adults from the INSIGHT Study.

People who reported more mentally stimulating experiences from childhood through older age were less likely to develop Alzheimer’s disease and tended to develop symptoms years later than peers with the lowest enrichment, according to an observational study published in Neurology.

A 20-year randomized controlled trial has shown that cognitive speed training, combined with booster sessions, reduces the risk of dementia diagnosis by 25 percent among older adults. The study, involving over 2,800 participants aged 65 and older, focused on a computer-based task requiring quick recall of visual details. While results are promising, experts urge caution due to the study's multiple outcome measures.

Researchers studying young adults with major depressive disorder have reported an unusual energy “signature” in both the brain and immune blood cells: higher ATP-related measures at rest, paired with a reduced ability to increase energy production when demand rises. The findings, published in Translational Psychiatry, may help explain common symptoms such as fatigue and low motivation, though the work is early and based on a small sample.

Brendan Clarey, deputy editor of Michigan Enjoyer, describes how replacing his iPhone with a Light Phone helped restore his attention span and creativity. He also eliminated his TV and limited computer use after work hours. The changes allowed him to read more, write creatively, and connect with others without digital distractions.

A new study finds that people over 80 who maintain sharp mental abilities, known as super agers, carry fewer copies of the main Alzheimer's risk gene and more of a protective variant. This genetic profile sets them apart even from other healthy seniors in the same age group. The research, led by Vanderbilt University Medical Center, highlights potential resilience factors against dementia.

Researchers have found that playing sounds associated with unsolved puzzles during REM sleep can help lucid dreamers solve those puzzles more effectively the next day. The study involved 20 participants who signaled awareness in their dreams through eye movements and sniffs. This technique, known as targeted memory reactivation, leverages the brain's memory processes to enhance learning during sleep.
