Stress disrupts memory precision, causing generalized fear responses by enlarging memory-encoding neuron networks. This effect, mediated by the brain’s endocannabinoid system, suggests potential therapeutic targets for conditions like PTSD and anxiety disorders.
Students with high confidence, enjoyment, and recognition of science’s value, combined with low perceived effort, achieved the highest science scores and aspirations.
Larger pupils and brighter irises in primate portraits elicited more positive impressions and greater donations, highlighting how subtle, often unnoticed eye features profoundly influence perceptions, emotions, and prosocial behavior.
Handwriting significantly enhances elementary students' ability to learn English words—shapes, sounds, and meanings—by engaging multisensory processes, improving accuracy and response times, and fostering deeper focus compared to visual learning.
People consistently underestimate their wrists' range of motion. This bias, likely an evolutionary safeguard against injury, prioritizes safety over precision in the brain’s internal representation of the body’s movement capabilities.
A study published in PLOS Computational Biology provides evidence that autistic traits play a significant role in how individuals navigate learning environments.
Non-neural cells can mimic memory-like behavior. These cells "remember" chemical patterns over time, showing that memory mechanisms aren't exclusive to the brain but rely on fundamental cellular processes.
Research published in Intelligence explores the power of polygenic scores to predict intelligence, finding that these genetic estimates explain about 6% of IQ variation.
A single 200 mg dose of doxycycline slightly improved memory and learning in healthy young adults, strengthened long-term motor memory, and had no harmful effects on other cognitive functions.
Recent research found higher prenatal fluoride exposure (above 0.3 mg/L in maternal urine) is linked to slightly lower IQ in children, suggesting a threshold for potential neurotoxicity, though no association was observed in low-exposure Danish cohorts.
A study has found that our brains detect face-like images faster than other visuals, even when suppressed from conscious awareness. Minimal facial features are enough to activate specialized brain mechanisms for face recognition.
Camembert cheese, fermented with white mold, produces fatty acid amides like myristamide that improved memory and learning in mice. These compounds boosted brain-supporting proteins and countered cognitive decline caused by a high-fat diet.
Intermittent "weekend warrior" exercise improves memory and keeps benefits longer than continuous workouts, according to new research on mice.
An eye-tracking study found that sugar-rich Christmas treats attract visual attention. Festive associations amplify this appeal, making it harder to resist sugary foods during the holidays.
Enjoyment, attention to time, and prospective memory errors influence the perception that annual events arrive faster, challenging the belief that aging accelerates time perception and highlighting psychological factors shaping our experience of time.
