Like to go your own way? Most of us actually prefer to follow the pack, according to research. That's one of the outcomes from a study that examines how mathematical models predict human behavior.
Researchers have been conducting evidence-based reviews of testing used for five domains -- attention, language, memory, spatial cognition, and executive function. New recommendations for improving this clinical cognitive testing have been provided by the researchers.
Researchers are looking for biomarkers that might serve as an early warning system for Alzheimer's disease. The process is not without complications, but these scientists possess a collective “Rosie the Riveter” spirit.
The ability to engage in mental time travel is a unique and central part of the human experience. And yet this very ability can have detrimental consequences for both physical and mental well-being when it becomes repetitive and uncontrolled. New research investigates this kind of repetitive thinking, exploring the core psychological processes that underlie maladaptive thought processes like worry and rumination.
Depression is a leading cause of disability worldwide, and treatment-resistant symptoms of depression have a terrible personal and societal cost. They can devastate lives, careers, and families. Some severely ill patients may be unable to attend to even the basic elements of self-care, while others attempt or complete suicide. Now researchers report the results of the first large-scale, randomized, sham-controlled trial of deep brain stimulation treatment for treatment-resistant symptoms of depression.
How do you get to Carnegie Hall? New research on the brain's capacity to learn suggests there's more to it than the adage that 'practice makes perfect.' A music-training study has found evidence to distinguish the parts of the brain that account for individual talent from the parts that are activated through training.
Early evidence suggests hybrid cochlear implants may benefit millions with common form of hearing loss
People with a common form of hearing loss not helped by hearing aids achieved significant and sometimes profound improvements in their hearing and understanding of speech with hybrid cochlear implant devices, according to a new multicenter study.
Policy makers need to take factors like geography, available skills and knowledge and the networks of local companies into account to boost the impact of higher education on economic development, according to a new paper.
Hormones play a two-part role in encouraging and reinforcing cheating and other unethical behavior, according to new research. With cheating scandals a persistent threat on college campuses and financial fraud costing businesses more than $3.7 trillion annually, researchers looked to hormones for more answers, specifically the reproductive hormone testosterone and the stress hormone cortisol.
The complex mechanisms of interaction and dynamics between the gut microbiota and its host have been illuminated by recent research. Data show that relatively minor changes in microbiota profiles or its metabolic activity induced by neonatal stress can have profound effects on host behavior in adulthood.
Depressive symptoms and mood in the moment may predict momentary pain among rheumatoid arthritis patients, according to researchers. Individuals in the study who reported greater depressive symptoms in general also reported more common pain and restrictions in daily life. This effect of depressive symptoms was not due to differences in day-to-day mood.
Are today's teen girls poised to close the gender gap tomorrow? A new research report suggests that teen girls face a powerful barrier to leadership: gender bias.
Every addiction is characterized by a strong desire for a certain addictive substance, be it nicotine, alcohol or other drug. Researchers recently conducted a study on heroin addiction and demonstrated that the stress hormone cortisol can reduce addictive cravings.
An entirely new control mechanism that regulates the function of mitochondria, the powerhouses of the cell, has been discovered by researchers. Surprisingly, a fatty acid is playing a key role in this process. The scientists have now reported that using fatty acid as a food additive improved disease symptoms in flies that suffer from Parkinson's-like symptoms due to dysfunctional mitochondria.
Are the same regions and even the same cells of the brain area called hippocampus involved in encoding and retrieving memories or are different areas of this structure engaged? This question has kept neuroscientists busy for a long time. Researchers have now found out that the same brain cells exhibit activity in both processes.
Diseases like Alzheimer's are caused when proteins aggregate and clump together. In a world first, scientists have successfully distinguished between the disease-causing aggregation forms of proteins. The finding can help change pharmaceutical treatment of neurodegenerative diseases.
Specific cardiovascular risk factors, such as alcohol consumption, smoking, obesity and diabetes, are associated with smaller regional brain volumes that may be early indicators of Alzheimer's disease and dementia according to a study.
Babies born very premature or severely underweight are at heightened risk of becoming introverted, neurotic, and risk averse as adults, indicates research. Very premature birth at less than 32 weeks and/or very low birthweight of less than 1500 g are known to be linked to a heightened risk of autistic spectrum behaviours, but it has not been clear if prematurity and low birthweight might affect other adult personality traits.
A strikingly new approach for treating Rett syndrome has been developed by scientists, a devastating autism spectrum disorder. In their report, the researchers demonstrate that treatment with small-molecule drug candidates significantly extends lifespan in male mice that model Rett and ameliorates several behavioral symptoms in females.
Compulsory schooling laws significantly increased school attendance rates, especially among lower-class children, and also shifted the occupational distribution toward skilled and non-manual occupations, a researcher has found.
