This is sort of scary research. We all like to think our views on moral issues are pretty consistent and not easily shaken. That would be incorrect. They are not consistent and they are easily shaken. At least these are the conclusions reached by this research. We’ve written before about on which side of the […]

If I gave you a written description of an object – let's say a boat – would you be able to judge whether the author had written about the boat from their memory of it, as opposed to having written about a boat they'd imagined?It's a question with real-world importance because, in court, we often rely on eyewitness memories and it's up to a jury to determine their source and veracity. But memory, like the imagination, is a creative process. Sometimes the two even become blurred – it's quite........ Read more »

"Asthmatic children had a higher risk of also having ADHD."That was the conclusion reached by Kirsten Holmberg and colleagues  based on their analysis of rates of ADHD, and other variables found "through the Swedish Twin Register, linked to the Swedish Medical Birth Register, the National Patient Register and the Prescribed Drug Register." Said data came from over 20,000 twins who's parents were questioned when children were aged 9 or 12 years.For those unfamiliar with the proposed conne........ Read more »

Childhood obesity affects more than double the amount of children it did 30 years ago, according to the Centers for Disease Control and Prevention(CDC). To figure out why the rate is increasing researchers studied the relationship between parents and their obese children to determine how to improve pediatric health. The study actually reveals how poorly parents rate their own child’s weight issues — at least until they reach extreme levels of obesity.... Read more »

"The autism sera injected rats demonstrated developmental delay and deficits in social communication, interaction, and novelty."That was one of the findings reported in the paper by Syed Faraz Kazim and colleagues  (open-access) who, among other things, injected intracerebroventricularly sera collected from children with autism into newborn rats and examined behavioural effects compared with injections of sera from asymptomatic controls. Actually, that was only one part of the resea........ Read more »

When you consider that so much of our energy and such a large portion of our behavioral repertoire is devoted to ways of ensuring our survival, suicide appears to be perhaps the most inexplicable human behavior. What would make this human machine--which most of the time seems to be resolutely programmed to scratch, claw, and fight to endure through even the most dire situations--so easily decide to give it all up, even when the circumstances may not objectively seem all that desperate? Suicide i........ Read more »
Sometimes being too focused on a task is not a good thing. During tasks that require our attention, we might become so engrossed in what we are doing that we fail to notice there is a better way to get the job done. For example, let’s say you are coming out of a New York City subway one late afternoon and you want to find out which way is west. You might begin to scan street signs and then suddenly realize that you could just look for the setting sun.... Read more »

A recurrent theme here in TheEGG is the limits and reliability of knowledge. These get explored from many directions: on epistemological grounds, from the philosophy of science angle, but also formally, through game theory and simulations. In this post, I will explore the topic of misbeliefs as adaptations. Misbeliefs will be intended as ideas about […]... Read more »

In the Journal of Personality, a new study reports on the uniformity of human experience around the globe: The World at 7: Comparing the Experience of Situations Across 20 Countries
The research was an online survey of a total of 5447 people. Each participant was asked to think about what happened the previous evening at 7 pm. Then they were asked to describe the 7 pm scene by means of 89 statements (descriptors), which included things like: "Rational thinking is called for.", "Situation ra... Read more »

"A positive screen on the M-CHAT [Modified Checklist for Autism in Toddlers] occurs more commonly in very preterm infants than those born at term."So said the study by Peter Gray and colleagues  as the topic of preterm status - that is, babies born alive before 37 weeks of pregnancy - potentially being linked to a greater risk of autism or at least, increased risk of screening positive for autism, crops up yet again on this blog (see here).Gray et al examined a cohort of children bo........

The sparring mitt, yellow stitches spelling "SLUGGER" casually lying on the desk. The Mathlete trophy on a high shelf. A Ganesha statue, slightly chipped. Why do people bring these kinds of personal objects into the workplace?Researchers Kris Byron and Gregory Laurence found answers by consulting 28 people in a range of jobs and workplaces. They used the "grounded theory" approach, starting with a clutch of more open-ended interviews and then pursuing the lines of inquiry that emerged, in every ........ Read more »

Is it cool or existentially disturbing to think that your personal brain quirks might come from the toys you played with as a toddler?
In a study published earlier this month, psychologists asked 6,588 American synesthetes what colors they associate with each letter of the alphabet. Then they compared these associations to a certain vintage set of Fisher-Price alphabet magnets. They found that at least 6% of their synesthetes had improbably close matches to the colors of the magnets.

There is a lot of literature on fire-setters but not, apparently, on how psychotic fire-setters differ from those who are not psychotic. As it turns out, there are some significant differences. Researchers in The Netherlands examined the records of 124 fire-setters (30 psychotic and 94 non-psychotic) sent for pretrial forensic mental health assessments between 2000 […]

A quote to begin: "acute inflammation can lead to decreases in the ability to accurately and reliably comprehend emotional information from others."It comes from the article published by Mona Moieni and colleagues  who examined a concept familiar to many people with a connection to autism either personally or professionally: Theory of Mind (ToM). Rather interestingly, Moieni et al "examined whether exposure to an experimental inflammatory challenge led to changes in ToM." Inflammato........ Read more »

Stereotypes about people can affect how we look at a person, but sometimes it causes other problems. Gender stereotypes about women’s ability in mathematics negatively impact their performance.

We hear in the media all the time, obesity is effecting our health. In most cases when we talk obesity we are talking about heart disease, sedentary activity, or chronic overeating.

Can we recognize if people around us are stressed, anxious or fearful without observing their facial expressions, body language and actions or hearing their voice and messages? Can we understand if we are stressed ourselves without assessing our heart rate, blood pressure, noticing dry throat, sweating, drops or surges in energy? Yes, we can - by using our nose - as humans, too, recognize and transmit their emotions through chemical senses.When we are stressed or panic we become more sensit........ Read more »
