Have you ever made a decision that, in hindsight, seemed irrational? A new study with mice, which could have implications for people, suggests that some decisions are, to a certain extent, beyond their control. Rather, the mice are hard-wired to make them.
If viewers sometimes feel guilty about binge-watching television programing, they really shouldn’t. Though its name implies impulsive behavior, binge-watching TV is a common activity planned out by viewers, suggests new research from the University of California San Diego’s Rady School of Management and School of Global Policy and Strategy.
Swedish obstetricians and gynecologists are noticeably more emotionally stable and conscientious compared to the majority of the Swedish population.
Plants are capable of responding to people and have behaviors comparable to tameness, according to authors of new research that calls for a reappraisal of the process of plant domestication, based on almost a decade of observations and experiments.
What gives one friend influence over another? Considerable attention has focused on who influences whom; much less is known about why one partner is prone to be influenced by the other. A study tested the hypothesis that within a friend dyad, having fewer friends than one’s partner increases susceptibility to influence, because it reduces dissimilarity and promotes compatibility. Results showed that partners with fewer friends were influenced by children with more friends. In each case, the partner with fewer friends became more similar to the partner with more friends. Academic engagement was the only domain where partners with fewer friends also influenced partners with more friends.
World Mental Health Day takes place on October 10 and comes at a time when mental health is reaching a breaking point, says Virginia Tech child psychology expert Rosanna Breaux. “We need to start thinking about mental health just like we…
Key differences in male and female mice brains provide new insights into how sex determines the mechanisms by which distinct synapses monitor and regulate dopamine signaling. The impact of sex differences is particularly pronounced when the mice express a human genetic variant found in boys with either ADHD or autism. Behavioral generalizations across the sexes may limit diagnosis of mental illness, especially if one sex translates alterations into outward signs such as hyperactivity and aggression vs. more internal manifestations such as learning, memory and mood, even when the same molecular pathology is at work.
Being a smoker makes it more likely for a person to have severe COVID-19 symptoms, require hospitalization or die, which may explain a sharp decrease in smoking behavior among the Danish population during the pandemic, according to new research.
JMIR Publications recently published “Reducing Treatment Burden Among People With Chronic Conditions Using Machine Learning: Viewpoint” in JMIR Biomedical Engineering which reported that the COVID-19 pandemic has illuminated multiple challenges within the health care system and is unique to those living with chronic conditions.
A UC San Diego clinical trial finds new Guided Self-Help program is effective in treating pediatric obesity and improving family attendance rates.
Menthol cigarettes increase youth smoking and nicotine addiction report researchers at the Herbert Wertheim School of Public Health and Human Longevity Science at University of California San Diego.
Graphic warning labels led smokers to hide their packs but not change other smoking behaviors according to report by University of California San Diego Herbert Wertheim School of Public Health and Human Longevity Science researchers.
More than 1 million United States youth became new daily tobacco users within two years, most were vaping e-cigarettes daily, report UC San Diego Herbert Wertheim School of Public Health and Human Longevity Science researchers.
About three-quarters of people were consistently honest, telling between zero and two lies per day. By contrast, a small subset of people averaged more than six lies per day and accounted for a sizable proportion of the lies, says researcher Timothy Levine, Ph.D.
Researchers tested the effectiveness of affordable, interactive robotic pet cats to improve mood, behavior and cognition in older adults with mild to moderate dementia.
A new paper in the Journal of the European Economic Association, published by Oxford University Press, indicates that we tend to listen to people who tell us things we’d like to believe and ignore people who tell us things we’d prefer not to be true.
A first in situ, long-term study explored how the common octopus, a medium-sized octopus widely distributed in tropical and temperate seas worldwide and the Atlantic longarm octopus, a small species of octopus found in the Atlantic Ocean and elsewhere, coexist by examining their foraging habits and tactics, diet, behaviors and when they are active or inactive. Results show that their very different behaviors and habits is exactly how these two species coexist in a shallow Florida lagoon- even at high densities.
Researchers identified 579 locations in the human genome associated with a predisposition to self-regulation-related behaviors, such as addiction. With data from 1.5 million people of European descent, the effort is one of the largest genome-wide association studies to date.
Researchers asked participants about their personal driving behaviors such as speed, changing lanes, accelerating and decelerating and passing other vehicles. They also asked them the same questions about their expectations of a self-driving car performing these very same tasks. The objective of the study was to examine trust and distrust to see if there is a relationship between an individual’s driving behaviors and how they expect a self-driving car to behave.
One of the biggest marketing trends in the online shopping industry is personalization through curated product recommendations; however, it can change whether people buy a product they had been considering, according to new University of California San Diego research.
A Herbert Wertheim School of Public Health and Human Longevity Science at University of California San Diego clinical trial showed that graphic warning labels on cigarette packaging changes perceptions of smokers to recognize the negative consequences of tobacco and consider quitting.
New UCLA-led research indicates that simple text messages emphasizing the easy availability of COVID-19 vaccines successfully boosted the number of people who got the shot.
The Covid-19 pandemic and the politicization of health-prevention measures such as vaccination and mask-wearing have highlighted the need for people to accept and trust science.
Trust in science makes people vulnerable to pseudoscience
