Motivation doesn’t have to be conscious; your brain can decide how much it wants something without input from your conscious mind. Now a new study shows that both halves of your brain don’t even have to agree. Motivation can happen in one side of the brain at a time.
Personalities come in all kinds. Now psychological scientists have found that the size of different parts of people’s brains correspond to their personalities; for example, conscientious people tend to have a bigger lateral prefrontal cortex, a region of the brain involved in planning and controlling behavior.
Two experiments found that although disgust sensitivity was not associated with explicitly condemning homosexual behavior, it was associated with unconsciously or implicitly judging it negatively.
According to research published in Group Dynamics: Theory, Research, and Practice in 2004, imagined ostracism is significant enough to induce psychological pain.
Children of drug abusers are at high risk for a wide-range of negative outcomes, including developmental and cognitive disabilities and substance abuse disorders.
Addiction and bipolar disorder are commonly co-occurring disorders, with up to 60% of individuals with bipolar disorder experiencing some form of substance abuse in their lifetime. While it is known that genetic factors contribute substantially to the likelihood of developing either illness, new studies suggest shared genetic roots for both disorders.
Today’s college students are not as empathetic as college students of the 1980s and ’90s, a University of Michigan study shows. The study, presented in Boston at the annual meeting of the Association for Psychological Science, analyzes data on empathy among almost 14,000 college students over the last 30 years.
A major study of people at risk for stroke showed that two medical procedures designed to prevent future strokes are safe and effective overall. Physicians will now have more options in tailoring treatments for their patients at risk for stroke.
A comprehensive behavioral therapy is more effective than basic supportive therapy and education in helping children with Tourette syndrome manage their tics, according to a study funded by the National Institute of Mental Health (NIMH). The study was published May 19, 2010, in a special issue of the Journal of the American Medication Association dedicated to mental health.
A family-based prevention program designed to help adolescents avoid substance use and other risky behavior proved especially effective for a group of young teens with a genetic risk factor contributing toward such behavior, according to a new study by researchers at the University of Georgia. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the National Institute on Drug Abuse (NIDA), components of the National Institutes of Health, supported the study, which appears in the May/June issue of Child Development.
Washing your hands “wipes the slate clean,” removing doubts about recent choices. That’s the key finding of a University of Michigan study published in the May 7th issue of Science.
In a new study, researchers scoured the genomes of several identical twin pairs, in which one twin had developed multiple sclerosis (MS) while the other did not. The researchers were searching for any genetic differences that could explain the twins’ different fates.
