David Anderson receives Rumelhart Prize for 30 years of research on human thought processes and learning, leading to effective computer-based tutoring systems. His work explores the neural basis of cognition, contributing to our understanding of the human mind.
Researchers found that musicians played at a tempo closer to fast music when listened to before playing, while speakers read faster or slower after hearing a recording's speaking rate. Both groups unconsciously coordinate timing to find a mutually agreeable tempo.
The RADAR project aims to develop a system that can save time for its user while improving decision quality. The system will handle routine tasks autonomously, ask for confirmation on others, and produce suggestions that users can modify.
Researchers have developed a new brain imaging technique called Voxel-based Lesion-Symptom Mapping (VLSM), which pinpoint areas of the brain most crucial for normal functioning. The method uses structural MRI scans and compares them to functional brain imaging data, allowing for more accurate mapping of brain damage and behavior.
Researchers found that DHEA did not significantly improve cognitive performance or ratings of disease severity in a randomized, double-blind trial. The study's small size and high drop-out rate may limit the findings, with larger studies needed to confirm the results.
A Rutgers researcher is using brain signal analysis to better understand attention deficit disorder (ADD) and schizophrenia. By monitoring brain activity in real-time, the study aims to identify common patterns of interaction that can help define brain profiles for individuals with these conditions.
A new brain imaging study from Washington University in St. Louis has shed light on the inner workings of human intelligence, revealing that individuals with higher fluid intelligence use specific brain regions to resist distraction and maintain focus. The study found that participants with higher fluid intelligence engaged several key...
Nicotine enhances activation in posterior cortical and subcortical regions of the brain, improving attention in smokers. The study found that nicotine helps focus attention on task demands by shifting cognitive resources from less used parts of the brain.
Scientists at Dartmouth College used fMRI experiments to locate the brain region that processes musical harmony, revealing a key area in the rostromedial prefrontal cortex. This discovery may help explain why music evokes strong emotions and behaviors.
A study published in the Journal of the American Medical Association found that training improved certain thinking and reasoning abilities in older adults. The training focused on developing strategies to improve memory, problem-solving, and concentration, but did not affect daily living skills.
Researchers found that high-performing elderly adults showed significantly more bilateral activity in the prefrontal cortex compared to low-performing older adults and young adults. This suggests the possibility of using training or drugs to enhance cognitive function in the elderly by increasing brain recruitment.
Rutgers psychologist Gallistel has been elected to the National Academy of Sciences, recognizing his research excellence and contributions to cognitive science. He is credited with introducing the idea that animals can think computationally, enabling them to navigate their world and anticipate events.
A six-month pilot study found that Ginkgo biloba improved performance on neuropsychological tests in patients with mild multiple sclerosis. About 50% of Americans with MS experience cognitive problems, and the herb may show a beneficial effect on attention, memory, and functioning.
A study found that participants with Alzheimer's disease showed greater discrepancies in cognitive skills, particularly in visual and verbal tests. The research suggests that non-invasive cognitive tests could detect early signs of the disease.
A study by scientists at Rush Alzheimer's Disease Center found that more frequent participation in cognitively stimulating activities is associated with a reduced risk of Alzheimer's disease. The research showed a 33% reduction in risk for each one-point increase in cognitive activity.
A collaborative study found that lifetime exposure to hormone replacement therapy (HRT) may be associated with better maintenance of cognitive function in older women free of dementia. The study included over 2,000 women aged 65 and older, who were followed for three years to assess changes in cognition and depression status.
A recent Indiana University study found that nearly one in four older African Americans have measurable cognitive problems, with prevalence increasing with age. Researchers also discovered that a significant proportion of those with cognitive impairment may progress to dementia within 18 months.
A study published in Neurology found that cognitive impairment No Dementia (CIND) affects 23.4% of community-dwelling participants aged 65 and older, with rates increasing by 10% for every 10 years after age 65.
Scientists have produced new adult neurons from precursor cells using a growth factor, which could potentially treat neurological diseases. The technique, supported by the NIH, involves introducing brain-derived neurotrophic factor (BDNF) into the adult rat brain.
Indiana University Professor David Shiffrin has been awarded the $100,000 Rumelhart Prize for his work on human memory and cognition. His findings have had a significant impact on the field of psychology, with many cited works continuing to influence research.
Researchers used fMRI scans to identify whether participants were imagining faces or places, achieving an accuracy rate of 85% in some trials. The study has implications for understanding the minds of individuals unable to communicate due to injuries or disorders.
A new $100,000 prize has been established at UC San Diego to honor human cognition pioneer David Rumelhart. The prize will recognize significant contributions in the field of human cognition and be awarded biennially.
A new study will investigate whether cognitive therapy can prevent relapses and recurrences of major depression as effectively as standard antidepressant medication. The study, funded by a $1.6 million NIMH grant, aims to help patients who suffer from recurring episodes of major depression.
A study using cognitive task analysis aims to develop more effective computer systems in healthcare by understanding human decision-making processes. The analysis focuses on skills, strategies, and problems of physicians dealing with complex decision situations.
A University of Michigan study found that older adults tend to use the left front side of the brain, specifically the dorsolateral prefrontal cortex, when performing concurrent tasks. This is a difference from younger adults who rely more on visual cortices for task switching.
Researchers found that patients with higher cognitive adaptation scores were less likely to experience a new heart attack or other coronary event six months after their angioplasty. Patients' ability to cope positively with their illness and take better care of themselves may play a key role in reducing the risk of future heart attacks.
Researchers found that the brain region critical for face perception is also active when humans become expert in recognizing novel objects, contradicting the idea of separate brain mechanisms. The study used functional magnetic resonance imaging to test adults on identifying greebles, a class of complex three-dimensional objects.
Researchers identified education and current health status as significant predictors of improved or maintained cognitive performance in older African Americans. The study also found that women are less likely to experience decline in cognitive functioning than men.
A study by Purdue University professor Theodore Wachs found that children from highly noisy homes experience less cognitive growth, delayed language skills, and increased anxiety. To mitigate these effects, parents can implement suggestions such as turning off the TV, establishing quiet spaces, and imposing a regular schedule.
