Brain areas associated with working memory also gauge the quality and uncertainty of memories. Researchers reveal details about the neural mechanisms of working memory that allow us to make decisions based on our certainty of memories.
Knowledge of an individual's personality can influence the perception of a face's identity and bias it toward unrelated people or identities, researchers report.
Study reveals the measures we take to prevent having to exert self-control in daily life.
Mouse mothers gathering their pups train female mice without pups to perform the same behavior. In virgin mice, observing the mother mouse take care of her pups stimulates oxytocin production, biologically shaping them for maternal behavior.
A new mathematical model incorporates fear, both of infection and vaccination, to better understand how pandemics occur in multiple waves of infection, as we are witnessing with COVID-19.
A new system within the brain uses for information processing and memory storage has been discovered. The findings provide novel insight into how the brain functions.
A new study strengthens previous research linking dental health to dementia and cognitive decline. Researchers found tooth loss is a risk factor for cognitive decline and dementia, and with each tooth lost, the risk for cognitive impairment increases.
A newly designed optical illusion is helping researchers better understand visual processing and perception. The illusion creates a subjective reality in what we see, highlighting the constructive nature of perception.
An increase in bad gum bacteria and a decrease in good bacteria is associated with amyloid-beta in cerebral spinal fluid samples of older adults. The findings add to the growing body of evidence linking periodontal disease to the development of Alzheimer's.
Contrary to popular belief, vulnerable narcissism is driven by personal insecurity and not an over-inflated sense of self. Researchers also found grandiose, or malignant, narcissism may be better understood as a manifestation of psychopathy.
The use of social media, specifically to drive "likes" to our content, follows a pattern of "reward learning", much like when an animal is trained to seek food rewards.
