Une étude lie la vivacité d'esprit quotidienne aux gains de productivité

Des chercheurs de l'Université de Toronto Scarborough ont découvert que se sentir mentalement vif au cours d'une journée peut augmenter la productivité jusqu'à 40 minutes. L'étude, publiée dans Science Advances, a suivi des étudiants universitaires pendant 12 semaines et a établi un lien entre une pensée plus claire et la définition ainsi que la réalisation d'objectifs plus ambitieux. Des facteurs tels que le sommeil et la charge de travail influencent ces fluctuations quotidiennes.

Une équipe dirigée par Cendri Hutcherson, professeure agrégée au département de psychologie de l'Université de Toronto Scarborough, a examiné comment les changements quotidiens dans la vivacité d'esprit affectent l'atteinte des objectifs. Les participants ont effectué des tests cognitifs quotidiens mesurant la vitesse et la précision de leur réflexion, tout en rendant compte de leurs objectifs, de leur productivité, de leur humeur, de leur sommeil et de leur charge de travail. Les jours où les étudiants se sentaient plus vifs que d'habitude, ils accomplissaient davantage de tâches et visaient plus haut, en particulier dans leur travail universitaire, indépendamment de traits de caractère comme la ténacité ou la maîtrise de soi. Hutcherson a souligné : « Tout le monde a des bons et des mauvais jours. Ce que nous saisissons, c'est ce qui différencie ces bons jours des mauvais. »

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.

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.
