Impressions shaped by facial appearance foster biased decisions

Research in recent years has shown that people associate specific facial traits with an individual's personality. For instance, people consistently rate faces that appear more feminine or that naturally appear happy as looking more trustworthy. In addition to trustworthiness, people also consistently associate competence, dominance, and friendliness with specific facial traits. According to an article published by Cell Press on October 21st in Trends in Cognitive Sciences, people rely on these subtle and arbitrary facial traits to make important decisions, from voting for a political candidate to convicting a suspect for a crime. Referring to this systemic bias as "face-ism," the authors present its real-world consequences and discuss potential ways of overcoming it.

Study suggests a novel approach for treating non-cardiac chest pain

Chest pain doesn't necessarily come from the heart. An estimated 200,000 Americans each year experience non-cardiac chest pain, which in addition to pain can involve painful swallowing, discomfort and anxiety. Non-cardiac chest pain can be frightening for patients and result in visits to the emergency room because the painful symptoms, while often originating in the esophagus, can mimic a heart attack. Current treatment—which includes pain modulators such as selective serotonin reuptake inhibitors (SSRI)—has a partial 40 to 50 percent response rate in alleviating symptoms.

Numerous studies have shown that individuals with an alcohol use disorder perform worse than those without one on multiple neurocognitive domains of function following detoxification from alcohol, although the level of impairment can vary widely among individuals. A new study of the degree of neurocognitive recovery in treatment-seeking alcohol dependent individuals (ALC) – with varied degrees of smoking status – during the first eight months of sustained abstinence from alcohol has found that smoking status influenced the rate and level of recovery.

Bar attendance supports heavy drinking by young adults in the US-Mexico border region

Due to a legal drinking age of 18 years, cheaper alcohol, and marketing tactics of local bars that specifically target youth, Mexico is an attractive and geographically nearby destination where younger U.S. residents legally drink heavily. However, levels of drinking on the U.S. side are high even among youth who did not recently travel to Mexico. A new study examined whether two factors typical of risky drinking in Mexico – bar attendance and permissive alcohol-related social-cognitions – might also explain higher drinking on the U.S. side, finding that patterns of bar attendance were strongly linked to higher drinking among U.S. border youth, but liberal social cognitions were not.

Understanding drinking behaviors among women with unwanted pregnancies

Most women reduce or stop drinking alcohol upon discovery of pregnancy. However, little information exists about changes in alcohol use, and factors contributing to these changes, among women with unwanted pregnancies. A new study examines changes in alcohol use from before pregnancy recognition to during pregnancy among women with unwanted pregnancies – meaning women who tried, but were unable, to terminate their pregnancies. Findings indicate that most women with unwanted pregnancies quit or reduce alcohol consumption once they discover their pregnancies, and that some may be substituting alcohol for drugs once they discover their pregnancies.

Bogus recycling bins help identify drinking patterns among low-income seniors

Substance abuse is the fastest growing health concern for older adults, a segment of the population that is likewise rapidly increasing. Heavy drinking among older persons is associated with an increased risk of health problems like diabetes, cognitive impairment, sleep issues, and depression.

Studies must be carried out to determine whether exercise slows the onset of type 1 diabetes in children and adults

Rates of type 1 diabetes—the autoimmune form of the condition that often begins in childhood and eventually results in lifelong dependency on insulin—are increasing in almost all nations worldwide. However, while it appears possible from research in other forms of diabetes that physical exercise could slow the progression of this disease, there have been no studies to date that explore this in patients with type 1 diabetes. In a paper published in Diabetologia (the journal of the European Association for the Study of Diabetes) researchers argue that such trials must be carried out to potentially benefit the millions of people affected by type 1 diabetes worldwide.
