Study Links Cognitive Deficits, Hearing Loss
The New York Times: There’s another reason to be concerned about hearing loss — one of the most common health conditions in older adults and one of the most widely undertreated. A new study by researchers at Johns Hopkins Medicine suggests that elderly people with compromised hearing are at risk of developing cognitive deficits — problems with memory and thinking — sooner than those whose hearing is intact. The study in JAMA Internal Medicine was led by Dr. Frank Lin, a hearing specialist and epidemiologist who over the past several years has documented the extent of hearing problems in older people and their association with falls and the onset of dementia.

Highlight this Blog Post at Your Own Risk
The Huffington Post: How did you study? It's question I often find myself asking college students during office hours when they come by to talk about a disappointing exam score or ask for suggestions for improving future performance. One thing you learn when you ask this question is that people approach studying in very different ways. Flashcards for key terms. Underlining. Diagrams for major themes. Writing summaries. Re-reading before the exam. There's no shortage of study strategies available to the diligent student. And, quite often, there's no shortage of confidence that the tactics each of us chooses are effective. ...

When Experts Go Blind
National Geographic: The picture above is an X-ray computed tomography (CT) scan of a human lung. Go ahead and take a few seconds to look at it carefully. How long did it take you to spot the gorilla? The image takes a starring role in a fun study in press at Psychological Science. Trafton Drew and colleagues at the Brigham and Women’s Hospital showed that when people focus on searching these images for bright white cancer nodules, they never notice the gorilla. More shocking, radiologists — who are trained to read CT scans — usually miss it, too. “It’s a vivid example that looking at something and seeing it are different,” says Drew, a postdoctoral fellow in Jeremy Wolf’s lab.

Shame About Past Alcoholism Predicts Relapse and Declining Health in Recovering Alcoholics
Feeling shame about past instances of problem drinking may increase the likelihood of relapse and other health problems, according to a new study in Clinical Psychological Science, a journal of the Association for Psychological Science. The study, conducted by researchers from the University of British Columbia, shows that behavioral displays of shame strongly predicted whether recovering alcoholics would relapse in the future. Public shaming has long been viewed as a way to encourage people to amend their ways and research suggests that experiences of shame can motivate people to improve their self-image and contribute to a common good.

Il razzismo si “vede” nel cervello delle persone (race bias increases differences in the brain’s representations of faces)
Wall Street Italia: In un futuro non molto lontano, le scansioni cerebrali potrebbero stabilire se un individuo ha una propensione al razzismo oppure no. Parola di alcuni scienziati, che hanno condotto uno studio che ha dato risultati sorprendenti, secondo cui le scansioni sarebbero capaci di individuare le differenze nel modo in cui gli esseri umani presentano determinate attitudini razziali verso la gente di colore o verso i bianchi.

The (Really Scary) Invisible Gorilla
The Huffington Post: The Invisible Gorilla is part of the popular culture nowadays, thanks largely to a widely-read 2010 book of that title. In that book, cognitive psychologists Dan Simons and Christopher Chabris popularized a phenomenon of human perception -- known in the jargon as "inattentional blindness" -- which they had demonstrated in a study some years before. In the best known version of the experiment, volunteers were told to keep track of how many times some basketball players tossed a basketball. While they did this, someone in a gorilla suit walked across the basketball court, in plain view, yet many of the volunteers failed even to notice the beast. ...
