It's more about altruism than trying to win approvalWhy do I tip my taxi driver, but not my accountant? I mean, there’s a good reason I don’t - he would narrow his eyes at me and ask if I was feeling ok. But why, in general, do we tip in some service contexts and not others; is it simply due to a quirk of history or the result of broader psychological patterns? Cornell University’s Michael Lynn suspected the latter, and in his new study published in the Journal of Economic Psychology, he o........ Read more »

"The prevalence of ID [intellectual disability] in WA [Western Australia] has increased over the past 10 years compared with previous estimates... This increase is associated in a large part with an increased prevalence of ASDs [autism spectrum disorder] for whom 70% had comorbid ID or an unknown level of ID."Those were some of the findings reported by Jenny Bourke and colleagues  (open-access available here). Drawing on data derived from the Intellectual Di........ Read more »

Go ahead, sketch a face on your note paper. Use a photo of someone as a guide if you want. Unless you're a trained artist, the chances are that you've made an elementary error, placing the eyes too far up the head, when it fact they should be halfway. Research suggests about 95 per cent of us non-artists tend to make this mistake and in a new study in the Psychology of Aesthetics, Creativity and the Arts, psychologists in America have attempted to find out why. The answer it turns out is rather ........ Read more »

We posted earlier this week about the new concept of “maladaptive daydreaming” and those researchers published a second article on an actual 14-item scale to assess whether a specific individual is a maladaptive daydreamer. Since it’s a strange area that may end up in the courtroom—we thought we’d share information and some of the items […]

"The subsample that no longer fulfilled an autism spectrum disorder had full-time jobs or studies (10/11), independent living (100%), and reported having two or more friends (100%)."So said the paper by Adam Helles and colleagues  continuing a research theme from this authorship group on what happens to autism, or rather Asperger syndrome, in the longer-term (see here). Indeed, if you have the time, the thesis from Helles covering this area of study is well worth a read (see here).This time a........ Read more »

How do you know when a farm animal is unhappy? Animal welfare researchers wish they had easy ways to measure malaise in pigs, or stress in cows. But those tools are lacking—which is why scientists in Australia studied sheep they'd dosed with Valium.
"Animals are not able to talk to express their emotions," says Caroline Lee, an animal welfare scientist at CSIRO in New South Wales. "We need to use other ways of understanding how they are feeling."
One such way is to look for changes in ... Read more »

Stigma is a major barrier preventing people with mental health issues from getting the help they need. Even in a private and anonymous setting online, someone with greater self-stigma is less likely to take that first step to get information about mental health concerns and counseling.

When we think of crime scene forensics, it’s easy to view it as the objective end of criminal investigation. Witnesses waffle, suspects slide around from the truth, and jurors can be misled by emotive evidence. but the physical evidence simply is what it is. Yet forensic work requires human judgment, and opens the door for human error: for example, a tendency to evaluate evidence differently depending on background information. Now a new study in Law and Human Behaviour suggests that investiga........ Read more »

"Children with ADHD [attention-deficit hyperactivity disorder] and ASD [autism spectrum disorder] had low levels of EPA [eicosapentaenoic acid], DHA [docosahexaenoic acid] and AA [arachidonic acid] and high ratio of n-6/n-3 PUFAs [polyunsaturated fatty acid] and these correlated significantly with symptoms.

Remember Walter Mitty? He was a fictional character who escaped his dull day-to-day existence by constructing elaborate daydreams wherein he was the hero rather than a wallflower. Well, apparently Walter was not so unusual. There are people who spend as much as 60% of their time lost in daydreams. These are people who realize their […]

Given my own research interest in the use of specific dietary modifications as possible intervention tools for some aspects of some autism (see here) I was more than interested to read the results published by Faezeh Ghalichi and colleagues  following their randomised-controlled trial of a gluten-free diet (GFD) including some 80 children diagnosed with an autism spectrum disorder (ASD).As part of an area of much discussion, debate and also heated argument down the years, the author........

I don't want to keep you today. Just long enough to draw your attention to the paper by Jones and colleagues  regarding "ongoing efforts toward identification of early biological markers specific to subphenotypes of ASD [autism spectrum disorder]."The potential biomarkers in question this time around were the cytokines/chemokines - those various signalling molecules that seem to have more than a few connections to important processes like inflammation - and how their profile ("mid-gestat........

Rapport between a client and therapist is important for therapy to be successful, and part of that is agreeing about the aims of the exercise. You’d think this would include the therapist and client agreeing about the specific nature of the client’s psychological problems. In fact, a new study in Psychotherapy Research finds disagreement isn't harmful to therapy and can even be beneficial.Rolf Holmqvist and his colleagues recruited 846 therapy clients as they started a course of therapy at a........

Anti-NMDA-receptor encephalitis is not something that I ever envisaged talking about so much on this blog primarily concerned with autism research. Describing an often severe form of encephalitis where the body mounts an immune response against self ("the NR1 subunit of the NMDA receptor"), this condition is more readily associated with the symptoms of psychosis than anything specifically autism-related.But yet again (see here and see here) I'm talking about peer-reviewed research suggestin........

Children respond better to learning setbacks when they believe that ability and intelligence are malleable – that is, when they have what psychologists call a "growth mindset" rather than a "fixed mindset". This immediately raises the question of how to cultivate a growth mindset in children.So far, there's been a lot of attention on how to praise children (it's better to focus on their effort and strategies rather than their ability), but not much else. Surprisingly, parents' mindsets (growth........ Read more »

Smog has been a part of modern life since the industrial revolution, unfortunately all that pollution isn't just hurting the environment -- but come on, you saw this coming... right?

How do you know when animals are working together? Just because two animals got something done jointly doesn't mean they cooperated. They might have succeeded by dumb luck, or trial and error. Scientists who study animal minds, though, would really like to know when cooperation happens on purpose—and how animal partners manage to communicate with each other.

We need canine science because common sense can lead us astray.Recently I wrote about why science matters to our dogs and cats, based on findings from Dr. Paige Jarreau’s research that suggests science blogs (like this one) may contribute to readers having a better knowledge of science.I thought of this again recently because a comment I often see from readers – on any kind of science story on the internet – is "don’t we know this already?
