Popular girls showed more skilful leadership than others, popular boys showed less. In classrooms around the world, there's an unwritten hierarchy, with most of the kids knowing each other's standing in terms of popularity. Past psychology research has looked into the ways that children and teens attain this status, including the ability to influence their peers, either in skilful, sensitive ways or through coercion and manipulation. A new study published in the Journal of Experimental Chil........ Read more »

'Can Screening with the Ages and Stages Questionnaire Detect Autism?' was the research question posed and partially answered in the paper by Sarah Hardy and colleagues  recently.Drawing on data from a very healthy sized cohort (~2800 toddlers) who were "screened with the ASQ-3 [Ages and Stages Questionnaire] and M-CHAT-R across 20 pediatric sites" in the United States, researchers suggested that there may be more to see when it comes to the use of ASQ-3 and the complicated topic of ........

A new study in PLoS Pathogens uses an experimental malaria in pregnancy model to show that malaria during pregnancy induces learning and memory impairments and depressive-like behaviour in offspring. The researchers show that the deficits are dependent on complement activation and provide the first evidence for a causal link between malaria in pregnancy, complement activation and neurodevelopment....

The human brain does not come with an operating manual. However, a group of scientists have developed a way to convert structural brain imaging techniques into “wiring diagrams” of connections between brain regions. Three researchers from UCSB’s Department of Psychological & Brain Sciences — Michael Miller, Scott Grafton and Matt Cieslak — used the structure of neural networks to reveal the fundamental rules that govern which parts of the brain are most able to exert cognitive control ........

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 »

Who doesn't enjoy waking to a pleasant smell wafting past? Unfortunately for them, the penguins in a recent study woke up not to pancakes frying nearby, but to less appetizing aromas—for example, feces on a stick. But scientists promise the experiment taught them valuable lessons about a penguin's capabilities. Besides, they let the birds go right back to sleep.
"Research into the sense of smell in birds has a bit of a dubious history," says Gregory Cunningham, a biologist at St. John F........ Read more »

As a juror in a criminal trial, you are meant to make a judgment of the defendant's guilt or innocence based on the evidence and arguments presented before you. In many trials, however, alongside the facts of the case, material and statements are allowed that don't in themselves speak to the culpability of the defendant. In a murder trial, for instance, a parent may take the stand and describe how their life has been destroyed by the loss of their child (the victim in the case). Similarly, the p........ Read more »

Anecdotally, anyone who's spent time around toddlers knows that they mostly don't like sharing their toys. Together with research showing that toddlers, like adults, get pretty attached to their things and are reluctant to give them up, this has led to a popular belief that toddlers are selfish by nature.But a team of developmental psychologists led by Julia Ulber has published new evidence in the Journal of Experimental Child Psychology that paints a more heart-warming picture. These psychologi........ Read more »
