Kids in atheist families are more altruistic! The study is sound, but what does it mean?

by Tom Rees in Epiphenom

You may have seen the buzz around a recent study which found that kids in atheist families are more altruistic than kids in religious families. Like any study that reinforces preconceptions of a vocal group, it was social media gold dust. I want to take a critical look at it and some of the objections [Read More...]... Read more »

by Dr. Jekyll in Lunatic Laboratories

Imagine that you are a female student and give the exact same answer to a physics exam question as one of your male classmates, but you receive a significantly poorer grade.

by BPS Research Digest in BPS Research Digest

From the pontifications of the politician on the nightly news, to the latest tabloid health scare, we're constantly bombarded by other people's arguments – their attempts to make a particular claim based on some kind of evidence. How best to evaluate all these assertions and counter-assertions? Some insights come from a new study in the journal Thinking and Reasoning that's compared the argument evaluation strategies of scientists (advanced doctoral students and post-docs in psychology) with t........

Fish oils for schizophrenia?

by Paul Whiteley in Questioning Answers

Hot on the heels of the peer-reviewed research-based suggestion that fish oil supplementation (high in omega-3 PUFAs) might have some rather important effects pertinent to the transition to full-threshold psychotic disorder for 'young people with an at-risk mental state' (see here), are the results from Tomasz Pawełczyk and colleagues [1].This time around it was a randomised, placebo-controlled trial "of either 2.2 g/day of n-3 PUFA, or olive oil placebo, with regard to symptom severity in firs........

Sources of Error: Epiphenomenalism (part 1)

by Sergio Graziosi in Writing my own user manual - Sergio Graziosi's Blog

Epiphenomenalism is one idea I’ve struggled with for a long time: to my eyes, it doesn’t make any sense. But more importantly, when applied to philosophy of mind, it seems to me that epiphenomenalism does a great deal of damage.…Read more ›... Read more »

Feeling sick? It’s evolution’s way of telling you to stay home

by Dr. Jekyll in Lunatic Laboratories

When you have a fever, your nose is stuffed and your headache is spreading to your toes, your body is telling you to stay home in bed. Feeling sick is an evolutionary adaptation according to a hypothesis put forward by Prof. Guy Shakhar of the Weizmann Institute’s Immunology Department and Dr. Keren Shakhar of the Psychology Department of the College of Management Academic Studies....

Serum folate levels in schizophrenia meta-analysed

by Paul Whiteley in Questioning Answers

So: "In conclusion, the present meta-analysis found that folate deficiency is associated to SZ [schizophrenia], and subgroups which did not reach enough statistical power need further investigation in the future."That was the research bottom line discussed in the paper by Dan Wang and colleagues [1] on a topic that has been of some interest to this blog down the years (see here and see here for example). Folate (folic acid if you will) is a pretty vital nutrient that, among other thing........ Read more »

Opioid Drugs for Mental Anguish: Basic Research and Clinical Trials

by The Neurocritic in The Neurocritic

The prescription opioid crisis of overdosing and overprescribing has reached epic proportions, according to the North American media. Just last week, we learned that 91% of patients who survive opioid overdose are prescribed more opioids! The CDC calls it an epidemic, and notes there's been “a 200% increase in the rate of overdose deaths involving opioid pain relievers and heroin.” A recent paper in the Annual Review of Public Health labels it a “public health crisis” and proposes “int........

Diners order more food and drink from larger waiters and waitresses

by BPS Research Digest in BPS Research Digest

Psychologists have already identified a multitude of factors – besides actually how hungry we are – that influence the amount we choose to eat, from the size of the portion, to the company we're dining with. To this list, we can now add the weight of our waiter or waitress. According to new field research in the journal Environment and Behaviour, when people are served by an overweight person, they are more likely to order desert, and they tend to consume more alcoholic drinks.The finding le........

Sleep apnoea and autism

by Paul Whiteley in Questioning Answers

Sleep apnoea defined as "a condition where the walls of the throat relax and narrow during sleep, interrupting normal breathing" is not natural fodder for this blog. When however it is mentioned in the context of autism as it was in the paper by Ikuko Hirata and colleagues [1] it becomes a little more relevant; more so when one realises that sleep issues and autism might actually be quite an important topic (see here).Hirata et al describe the assessment of sleep problems in "965 commu........

Follow your heart – Having an unanswered calling in life is worse than having no calling at all

by BPS Research Digest in BPS Research Digest

As you return to work after the holidays, do you have a sense that this isn’t the place you’re meant to be; that somewhere out there is a calling as yet unanswered? If so, you better do something about it, according to new research published in the Journal of Vocational Behaviour. Having an unanswered calling leads to poorer life outcomes than having no calling at all, and it could even harm your health.We already know that people who follow an occupational calling have better life outcomes ........

How and when to send sarcastic emails and texts, according to science

by BPS Research Digest in BPS Research Digest

If you want someone to realise you're beingsarcastic, add a winking emoticon. A big problem with being sarcastic in your texts or emails, of course, is that you can't use tone of voice or a cheeky smile to ensure your recipient realises that you're not being literal. Help is at hand from a new study in the Quarterly Journal of Experimental Psychology that compared the effectiveness of different forms of punctuation and emoticons at helping to convey text-based sarcasm. The study also a........ Read more »

The epidemiology of suspected autism in Shenzhen, China

by Paul Whiteley in Questioning Answers

I read with interest the paper by Weikang Yang and colleagues [1] (open-access) talking about "a high prevalence rate of suspected autism in children" in Longhua District, Shenzhen (China).Detailing results based on the administration of the Autism Behavior Checklist (ABC) to some 15,000 children - "with a response rate of 91.2 %" - authors describe how approximately 2.6% of participants scored higher than 67 on the ABC and thus "had a high probability of autism" and a furthe........

Schizophrenia linked to loss of cells in the brain’s memory center

by Dr. Jekyll in Lunatic Laboratories

Scientists at Columbia University’s Mortimer B. Zuckerman Mind Brain Behavior Institute, Columbia University Medical Center (CUMC), and the Université Paris Descartes have found that deficits in social memory–a crucial yet poorly understood feature of psychiatric disorders such as schizophrenia–may be due to a decrease in the number of a particular class of brain cells, called inhibitory neurons, in a little-explored region within the brain’s memory center....

Students who believe they have more "free will" do better academically

by BPS Research Digest in BPS Research Digest

Psychologists are coming to realise that it's not just people's abilities that are important in life but their beliefs about their abilities. Much of this research has focused on whether people think traits like intelligence and self-control are fixed or malleable, with those individuals who endorse the idea of malleability tending to fare better at mental tasks and even at life in general, at least as measured by their feelings of well-being.Now a study in Personality and Individual Differences........

Gender dysphoria and autistic traits?

by Paul Whiteley in Questioning Answers

"Gender dysphoria is a condition where a person experiences discomfort or distress because there is a mismatch between their biological sex and gender identity."That's how NHS Choices describe gender dysphoria illustrating how biological sex and gender identity are not always one and the same for everyone. I might add that science is also coming around to the idea that the dichotomy of two biological sexes (male and female) might also not be as accurate as we've all been led to believe.With........
