Less reward, more aversion when learning tricky tasks We celebrate our triumphs over adversity, but let’s face it: We’d rather not experience difficulty at all.

Where’d you get that great idea? Scientists seek the source of creativity It’s commonly believed that creativity is a process that involves connecting ideas and building on the past to create something new.

Children born just after the Berlin Wall fell were lower achievers – here’s why Germany and the rest of Europe are celebrating the 25th anniversary of the collapse of the Berlin Wall and the associated communist regimes in Eastern Europe.

Following the collapse of the Communist regimes, fertility [...]The post Children born just after the Berlin Wall fell were lower achievers – here’s why appeared first on PsyPost.
Oxytocin levels in blood, cerebrospinal fluid are linked, study finds For years, scientists have debated how best to assess brain levels of oxytocin, a hormone implicated in social behaviors. Now, researchers have found the first direct evidence in children that blood oxytocin measurements are tightly linked to levels of oxytocin in cerebrospinal fluid, which bathes the brain.

That is, the more anxious a person is, the more likely they are to notice threatening things around them. This is called the threat bias.

Hallucinogenic bullets An article in the American Journal of Forensic Medicine & Pathology discusses the history of ‘modern toxic antipersonnel projectiles’ and it has a short history of ammunition designed to introduce incapacitating hallucinogenic substances into the body.

Fanaticism Is a Disease Like Alcoholism We get distracted by the beliefs of particular fanatics and fail to see fanaticism's common traits. It's not what they belief but how they believe it. Fanaticism is a disease much like alcoholism. We hate the fanatic, which makes it hard for him to change. We need a AA-style approach instead: Don't blame the beliefs or the believers, blame the disease.
Thinking about the long-term impact of your food choices may help control food cravings A new study adds evidence to the current thinking that individuals with obesity can successfully reduce cravings using distract tasks. For this study, researchers tested the effects of three, 30-second distraction techniques to reduce cravings for the study participant’s favorite foods. They found that the effect of tapping one’s own forehead and ear with their index finger, tapping one’s toe on the floor, or a control task of staring at a blank wall, all worked significantly to reduce the cravings; however, forehead tapping worked best out of all techniques.

Brain anatomy differences between autistic, typically developing individuals are indistinguishable 'Our findings offer definitive answers regarding several scientific controversies about brain anatomy, which have occupied autism research for the past 10 to 15 years,' says one expert. 'Previous hypotheses suggesting that autism is associated with larger intra-cranial gray matter, white matter and amygdala volumes, or smaller cerebellar, corpus callosum and hippocampus volumes were mostly refuted by this new study.'
Radiation a risk factor for brain tumors in young people, study finds In people under age 30, radiation is a risk factor for a type of brain tumor called a meningioma, a study has found. Researchers analyzed records of 35 patients who were diagnosed with meningiomas before age 30. Five had been exposed to ionizing radiation earlier in their lives. They include two patients who received radiation for leukemia at ages 5 and 6; one who received radiation at age 3 for a brain tumor known as a medulloblastoma; and one who received radiation for an earlier skull base tumor that appeared to be a meningioma. The fifth patient had been exposed at age 9 to radiation from the Chernobyl nuclear power plant disaster in Ukraine.
