Stress Higher in Children With Depressed Parents

Children with depressed parents get stressed out more easily than children with healthy parents—if the depressed parents are negative toward their child. That’s the conclusion of a study published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science.

The study is part of a long-term look at how a child’s early temperament is related to the risk for depression. The children were recruited for the study when they were three years old, an age when depression is rare. Thus, the researchers expect to see depression appear as the children grow. (more…)

GAINESVILLE, Fla. — Oral disease occurs commonly and progresses rapidly among people who have HIV, but the process is poorly understood. Researchers suspect that the culprit is a change in the makeup of bacterial communities that live in the mouth. (more…)

Sara Rockwell is a leader in her field. A professor of therapeutic radiology and pharmacology at the School of Medicine, Rockwell was among the first researchers to study the effects of oxygen deficiency on the response of malignant cells to radiation and anticancer drugs, and was among the first to consider the implications of this deficiency in microscopic tumors for the development of solid malignancies.

Rockwell, who is also associate dean for scientific affairs, joined the faculty of Yale School of Medicine in 1974, and teaches radiation biology, pharmacology, cancer biology, ethics and career development skills. She earned her bachelor’s degree in physics from Penn State University in 1965. She went on to earn her doctorate degree in biophysics from Stanford University in 1971. (more…)

Am I Safe Here?: How People With HIV/AIDS Perceive Hidden Prejudices in Their Communities

People in marginalized groups, such as the disabled or racial minorities, feel stigmatized—condemned, feared, or excluded—when other people stigmatize them. That’s obvious. But they can also feel stigma when nobody blatantly discriminates against them or says a negative word.

These folks aren’t paranoid, suggests a new study of HIV-positive people and their communities to be published in Psychological Science, a journal of the Association of Psychological Science. Rather, they’re picking up subtle clues from their communities. (more…)

Less than seven hours of sleep each night is leading to a host of sleep-related problems including drowsy driving and difficulty concentrating at work, according to two new studies released on Thursday.

Roughly one-third of adults in 12 states reported getting less than seven hours of sleep each night with about the same number saying they’ve unintentionally dozed off during the day, according to one of the studies on sleep-related behavior from the Centers for Disease Control and Prevention.

For Alcoholics, New Help in Abstaining—Without Thinking About It

Alcoholism is a tough addiction to kick. Eventually, most people return to drinking. But some Dutch and German psychological scientists have tested a short-term regime that promises to help alcoholics stay sober. Their study is published in Psychological Science, a journal of the Association of Psychological Science.

Heavy drinkers tend to behave impulsively in response to temptation. Meanwhile, their “reflective,” or controlled, responses—the thoughts that would help them resist drinking—are often weak. Most therapies, including Cognitive Behavior Therapy, primarily address the reflective responses. “They deal with the reasons and strategies” for sobriety, said University of Amsterdam experimental psychologist Reinout W. Wiers, the study’s lead author. To boost treatment success, his team developed cognitive-bias modification, or CBM, which, for the first time, “tries to turn around those impulsive responses.” (more…)

ANN ARBOR, Mich.— A non-invasive brain imaging technique gives new hope to patients with Parkinson’s disease in finding new and better treatment plans and tracking the disease progression, a new University of Michigan study shows.

The technique uses an MRI to measure resting state brain activity oscillations, said Rachael Seidler, associate professor in the School of Kinesiology and the Department of Psychology, and study author. (more…)

Optimism Cures Heart Diseases

Heart patients with an optimistic outlook are more likely to be healthier down the road and survive longer than those with less rosy views, new research suggests.

A study reported this week in the Archives of Internal Medicine that followed 2,800 heart patients found that those with more positive attitudes about their recovery had about a 30 percent greater chance of survival after 15 years than patients with pessimistic leanings. (more…)
