According to the National Institute of Mental Health, social anxiety disorder affects approximately 15 million American adults and is the third most common mental disorder in the United States, after depression and alcohol dependence.
The essential feature of the disorder is the fear of being evaluated by others, with the expectation that such an assessment will be negative and embarrassing. It tends to run a chronic and unremitting course and often leads to the development of alcoholism and depression. The disorder most often surfaces in adolescence or early adulthood, but it can occur at…
Martin Fischer, University of Dundee, Scotland, recently reported results showing that the majority of adults prefer to start counting on their left hand, regardless of whether they are left- or right-handed. In a subsequent odd-even task, the left-starters had more consistent spatial-numerical associations than the right-starters.
Simple numerical tasks, such as classifying digits as odd or even by pressing left or right buttons reveal that we like to associate small numbers with left space. Where does this preference come from?
The link between finger counting habits and numerical…
Not long ago, Howard Wainer, a statistician I mentioned recently, learned that his blood sugar was too high. His doctor told him to lose weight or risk losing his sight. He quickly lost about 50 pounds, which put him below 200 pounds. He also started making frequent measurements of his blood sugar, on the order of 6 times per day, with the goal of keeping it low.
It was obvious to him that the conventional (meter-supplied) analysis of these measurements could be improved. The conventional analysis emphasized means. You could get the mean of your last n (20?) readings, for example. That told…
Older adults with low blood levels of vitamin D and high blood levels of a hormone secreted by the parathyroid glands may have a higher risk of depression, according to a report in Archives of General Psychiatry.
About 13 percent of older individuals have symptoms of depression, and other researchers have speculated that vitamin D may be linked to depression and other psychiatric illnesses, according to background information in the article.
“Underlying causes of vitamin D deficiency such as less sun exposure as a result of decreased outdoor activity, different housing or clothing habits and…
Parents of children with autism were roughly twice as likely to have been hospitalized for a mental disorder, such as schizophrenia, than parents of other children, according to an analysis of Swedish birth and hospital records by a University of North Carolina at Chapel Hill researcher and colleagues in the U.S. and Europe.
The study examined 1,237 children born between 1977 and 2003 who were diagnosed with autism before age 10, and compared them with 30,925 control subjects matched for gender, year of birth and hospital. The large sample size enabled researchers to distinguish between…
Are you exhausted? Do you have pain all over but can’t figure out what’s wrong? If so, you may be suffering from fibromyalgia, a chronic condition that causes exhaustion, sleep disturbances and diffuse pain in your muscles, tendons, and ligaments.
Fibromyalgia patients experience a range of symptoms of varying intensities that increase and decrease over time and often resemble other conditions. For years, because of their complex nature and a lack of research on the condition, many doctors misdiagnosed fibromyalgia symptoms or dismissed them as being in the patient’s head. Even today, it is…
From the war room to the board room, negotiations are a part of everyday life. Successful negotiations demand a clear understanding of one’s opponent. But what approach should one take to achieve such an understanding of one’s opponent in everyday negotiations?
Psychologist Adam Galinsky from the Kellogg School of Management at Northwestern University, and colleagues William Maddux (INSEAD), Debra Gilin (St. Mary’s U.), and Judith White (Dartmouth) asked a similar question and found that success in negotiations depends on focusing on the head and not the heart. In other words, it is better to…
Looking on the bright side can lead to irresponsible financial behavior, says Elizabeth Cowley from the University of Sydney. In a series of studies, Cowley examined repeated gambling in the face of loss. She finds that people often engage in too much positive thinking, selectively focusing on one win among hundreds of losses when they think back on the overall experience.
“When we want to justify engaging in an activity which could potentially be irresponsible – like gambling – we may need to distort our memory of the past to rationalize the decision,” Cowley explains. “People who have…
True agoraphobia is an invalidating disease but a paper by Giovanni A. Fava and associates of the University of Bologna, published in Psychotherapy and Psychosomatics, questions the excessive emphasis on panic which has been attributed in the past decade and the role of pharmaceutical industry in this attribution.
In studying the phenomenology of panic attacks, Argyle and Roth noticed that truly spontaneous attacks, not preceded by anxiety-provoking cognitions, were uncommon.
Patients meeting positive criteria for panic disorder suffered from the whole range of anxiety disorders, and a…
In mice, child neglect is a product of both nature and nurture, according to a new study.
Researchers from the University of Wisconsin-Madison describe a strain of mice that exhibit unusually high rates of maternal neglect, with approximately one out of every five females failing to care for her offspring. By comparing the good mothers to their less attentive relatives, the group has found that negligent parenting seems to have both genetic and non-genetic influences, and may be linked to dysregulation of the brain signaling chemical dopamine.
As a possible model for human child neglect,…
