Memory bias
Memory biases may either enhance or impair the recall of memory, or they may alter the content of what we report remembering. There are many memory biases including the humor effect, positivity effect and the generation effect. The humor effect states that humorous items are more easily remembered than non-humorous ones. Positivity effects states that older adults favor positive over negative information in their memories. Generation effect states that self-generated information is remembered best.

Oct. 31, 2025 — People living in socially and economically disadvantaged neighborhoods may face higher dementia risks, according to new research from Wake Forest University. Scientists found biological signs of Alzheimer’s and vascular brain disease in those from ...
Oct. 30, 2025 — From mini-brains to spider-inspired gloves and wolf apple coatings, scientists are turning eerie-sounding experiments into real innovations that could revolutionize health and sustainability. Lab-grown brain organoids may replace animal testing, ...
Oct. 30, 2025 — Researchers used supramolecular nanoparticles to repair the brain’s vascular system and reverse Alzheimer’s in mice. Instead of carrying drugs, the nanoparticles themselves triggered natural clearance of amyloid-β proteins. This restored ...
Oct. 29, 2025 — People with gum disease may have higher levels of brain white matter damage, a new study finds. Researchers observed that participants with gum disease had significantly more white matter hyperintensities, even after accounting for other risk ...
Oct. 29, 2025 — New research reveals that intelligence plays a key role in how well people process speech in noisy environments. The study compared neurotypical and neurodivergent individuals and found that cognitive ability predicted performance across all groups. ...
Oct. 27, 2025 — Generalized anxiety disorder affects millions, often trapping sufferers in cycles of fear and isolation that conventional medications barely relieve. At UCSF, neuroscientist Jennifer Mitchell is testing a pharmaceutical form of LSD called MM120, ...
Oct. 26, 2025 — GLP-1 drugs, originally developed for diabetes and obesity, may also curb addictive behaviors by acting on reward circuits in the brain. Early trials show reductions in alcohol intake, opioid seeking, and nicotine use. Though more research is ...
Oct. 25, 2025 — A new study shows that eating more fruits and vegetables during the day can significantly improve sleep that same night. Researchers found a clear link between diet quality and sleep depth, with participants who met the CDC’s daily produce ...
Oct. 25, 2025 — Researchers found that neurons can use fat, not just sugar, to power the brain. When a protein called DDHD2 fails, this process breaks down and leads to serious brain problems. Scientists were able to restore damaged cells by feeding them fatty ...
Oct. 25, 2025 — Inside your body, an intricate communication network constantly monitors breathing, heart rate, digestion, and immune function — a hidden “sixth sense” called interoception. Now, Nobel laureate ...
Oct. 24, 2025 — A massive genetic study found that naturally lower cholesterol is linked to a dramatically reduced risk of dementia. The research simulated the effects of cholesterol-lowering drugs and showed up to an 80% lower risk for certain genetic profiles. ...
Oct. 24, 2025 — Researchers have finally seen and measured the tiny alpha-synuclein oligomers that may ignite Parkinson’s disease. With the ultra-sensitive ASA-PD imaging method, they captured these clusters in brain tissue, finding larger and more numerous ...
