Researchers at the UNC School of Medicine found that people with anorexia nervosa have very different microbial communities residing inside their guts compared to healthy individuals and that this bacterial imbalance is associated with some of the psychological symptoms related to the eating disorder....

Everyone knows that exercise improves health, and ongoing research continues to uncover increasingly detailed information on its benefits for metabolism, circulation, and improved functioning of organs such as the heart, brain, and liver. With this knowledge in hand, scientists may be better equipped to develop “exercise pills” that could mimic at least some of the beneficial effects of physical exercise on the body. But a review of current development efforts ponders whether such pills will........ Read more »

Well bad news for those of us who have a sweet tooth, a diet high in processed fructose sabotages rat brains’ ability to heal after head trauma, UCLA neuroscientists report.

In pop culture, conspiracy believers — like FBI agent Fox Mulder on The X Files or professor Robert Langdon in The Da Vinci Code — tend to reject the notion of coincidence or chance; even the most random-seeming events are thought to result from some sort of intention or design. And researchers have suggested that such a bias against randomness may explain real-world conspiracy beliefs. But new research from psychological scientists shows no evidence for a link between conspiracist thinking ........ Read more »

The AVE–SV comparison (Fornell & Larcker, 1981) is certainly the most common technique for detecting discriminant validity violations on the construct level. An alternative technique, proposed by Henseler et al. (2015), is the heterotrait–monotrait (HTMT) ratio of correlations (see the video below). Based on simulation data, these authors show for variance-based structural equation modeling (SEM), […]... Read more »

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have uncovered a significant–and potentially treatable–relationship between a chemical that helps transmit signals in the brain and genetic mutations present in a subset of individuals with autism spectrum disorder. The new research findings focus on the role that the neurotransmitter serotonin plays in the development of social behavior.... Read more »

It’s pretty well established now that there is a statistical connection between intelligence and non-belief. The effect is small, but it’s consistent and has been shown many times. Education, however, is a different matter. Some studies show that educated people are more religious, while others find they are less religious. Now there’s an obvious problem [Read More...]...

The role of the immune system in Alzheimer’s disease is a hot topic, but exactly how the two are connected and what interventions could help lower risk remain a mystery. In a new study, researchers in the Ann Romney Center for Neurologic Diseases at Brigham and Women’s Hospital (BWH) investigate how genetic risk factors for Alzheimer’s disease may influence a key type of immune cell. Their results lay the groundwork for designing better therapeutic strategies and better prediction tools fo........ Read more »

Does this sight make you want to yawn? A yawning Japanese macaque by Daisuke Tashiro at Wikimedia Commons.Do you think it would make other animals want to yawn? Many animals yawn spontaneously, but yawning in response to sensing or thinking about someone else doing it may be a completely different thing. Contagious yawning requires a sense of social connection and emotional empathy that not all species share. So far, scientists have found experimental evidence of contagious yawning in humans, ch........ Read more »

A woman who won’t drive long distances because she has panic attacks in the car. A man who has contamination fears so intense he cannot bring himself to use public bathrooms.

A remarkable paper just published in PLoS ONE reports on what is, I think, one of the largest psychological experiments of all time.
Researchers Elizabeth L. Paluck and colleagues partnered with a TV network to insert certain themes (or messages) into popular dramas shown on US TV. They then looked to see whether these themes had an effect on real world behavior, ranging from Google searches to drink-driving arrests.
The study was based on three prime time Spanish-language dramas (tele... Read more »

Social networking makes it easy to monitor the status and activities of a former romantic partner, an often unhealthy use of social media known as interpersonal electronic surveillance (IES) or, more commonly, “Facebook stalking.” Psychological and relationship factors and how individuals cope with the termination of a romantic relationship can help predict their use of online surveillance, according to a new study....

A team led by researchers at Cold Spring Harbor Laboratory (CSHL) has published a new analysis of data on the genetics of autism spectrum disorder (ASD).

For adults, memories tend to fade with time. But a new study has shown that there are circumstances under which the opposite is true for small children: they can remember a piece of information better days later than they can on the day they first learned it. While playing a video game that asked them to remember associations between objects, 4- and 5-year-olds who re-played the game after a two-day delay scored more than 20 percent higher than kids who re-played it later the same day....
