"At the end of 2013, the prevalence among children born in 2006 was 1 case of autism spectrum disorder per 46 children or 215.77 per 10 000."That was the conclusions reached in the study by Lorine Pelly and colleagues  looking at "the incidence and 1-year cohort prevalence for autism spectrum disorders in children less than 15 years of age and living in the Avalon Peninsula at the time of diagnosis." The Avalon Peninsula by the way, is located in Canada.Looking at data derived from the "........ Read more »

Having friends who suffer from depression doesn’t affect the mental health of others, according to research. The team found that having friends can help teenagers recover from depression or even avoid becoming depressed in the first instance. The findings are the result of a study of the way teenagers in a group of US high schools influenced each others’ mood. The academics used a mathematical model to establish if depression spreads from friend to friend.... Read more »

If you while away time in a games arcade – play some coin pushers here, a few fruit machines there – you will soon be familiar with that frustrating and enlivening sensation of the near win that follows getting four cherries out of five. New research from INSEAD suggests that these tantalising near wins produce high levels of motivational arousal, that encourage us to chase whatever alternative rewards are then available.In one fascinating experiment, Monica Wadhwa and JeeHye Christine Kim g........

Spending time observing an aquarium leads to improvements in mood and reductions in heart rate.There are psychological benefits to watching fish and crustaceans in an aquarium, according to a new study by Deborah Cracknell et al. They observed people’s natural interactions with a marine life display, and took heart rate, blood pressure and questionnaire results from 84 experimental participants. But the display wasn’t a fish tank that you could fit in your living room – it was a large exhi........ Read more »

How scientists study the effects of marijuana on the brain is changing. Until recently marijuana research largely excluded tobacco users from its participant pool, but scientists have found reason to abandon this practice, uncovering significant differences in the brains of individuals who use both tobacco and marijuana and the brains of those who only use marijuana....

Any college student can tell you that overstudying is a waste of energy. When your resources are limited, you should learn the material that's going to be on the test and ignore everything else. Certain blood-sucking bugs use the same strategy—unfortunately for the humans who catch diseases from them.
Kissing bugs live all around the Americas and drink the blood of other animals, including humans. They prefer to bite their hosts on the face—hence "kissing." The species that live in t........ Read more »

A psychologist based in Italy says he has found a simple way to induce in healthy people an altered state of consciousness – simply get two individuals to look into each other's eyes for 10 minutes while they are sitting in a dimly lit room. The sensations that ensue resemble mild "dissociation" – a rather vague psychological term for when people lose their normal connection with reality. It can include feeling like the world is unreal, memory loss and odd perceptual experiences, such as see........ Read more »

Tall ships @ Paul WhiteleyThe paper by Luis Lozada and colleagues  (open-access) brings back into focus a topic that has graced this blog before (see here) with their observation that: "Children who develop ASD [autism spectrum disorder] are more likely to have an admission with a diagnosis of jaundice in the neonatal period and more likely to require treatment for this jaundice."Jaundice, by the way, refers to a condition marked by yellowing of the skin and eyes as a result of........

An experiment to determine the effects of positive and negative user comments to items posted by media organizations on Facebook news channels showed, surprisingly, that the influence of user comments varied depending on the type and number of user comments. Negative comments influenced the persuasiveness of a news article, while positive comments did not, and a high number of likes did not have the expected bandwagon effect.... Read more »

Alzheimer’s disease is a degenerative brain disorder that is similar to senile dementia except that it begins in the later stages of life, usually after 40 years. Among the first signs and symptoms of the disease are impaired memory along with impaired thought and speech. However, these signs and symptoms appear after a significant damage to the brain.
This disease (along with many other psychiatric problems such as Parkinson’s) can be detected by doctors and experts with the help........ Read more »

Here’s a new way to measure our awareness of our own biases in four easy questions. Yes. Four. We are constantly writing about bias here and when we see ways to measure bias it is usually convoluted or prohibitively expensive, or contains language not suitable for courtroom use. This scale, however, is different—it is short […]

If you overheard someone at work refer to you as "a real political operator", would you feel complimented, or alarmed? The latter turns out to be a sensible reaction, as new research suggests that supervisors and colleagues have less faith in the performance of the highly politically skilled.Study authors Ingo Zettler and Jonas Lang noted a conundrum in their field: researchers treat political skill as a uniform good, the more the better, yet a meta-analysis of relevant research (pdf) found a sp........

You've heard that romance starts in the kitchen and not in the bedroom. Well, researchers at Drexel University finally have the science to support that saying - but not the way you might think. Researchers found that women's brains respond more to romantic cues on a full stomach than an empty one. The study explored brain circuitry in hungry versus satiated states among women who were past-dieters and those who had never dieted.... Read more »
