By guest blogger Vaughan BellCan you think a thought which isn’t yours? A remarkable new study, led by psychologist Jay Olson from McGill University in Canada, suggests you can. The research, published in Consciousness and Cognition, used a form of stage magic known as “mentalism” to induce the experience of thoughts being inserted into the minds of volunteers. It is an ingenious study, not only for how it created the experience, but also for how it used the psychology lab as both a stage ........ Read more »

I first heard the term “over-valued belief” back in the mid-1990’s when I worked in forensic rehabilitation with a man adjudicated not guilty by reason of insanity. He had been very ill (psychotic) and very violent when unmedicated (and had killed more than once due to delusional beliefs) but had been in treatment and well-medicated […]

Continuing a recent 'probiotic theme' on this blog I've decided to talk a little about the study results reported by Shelly Buffington and colleagues  on how a "single species of gut bacteria can reverse autism-related social behavior in mice." I say 'talk about' but my conversations on this topic should be viewed in light of what others have also said about this study (see here for example) including the lead author (see here).To summarise the findings: authors started from the idea that mat........

In a word, maybe. Apparently, it all depends on whether your focus is on differences between you and others or similarities when it comes to genetic makeup. The researchers had Jewish and Arab participants read a new articles which (naturally) cited a scientific article reporting either high genetic similarities or high genetic differences between Jews […]

An example of imagery used in the study by Coeval et alThe idea that homophobia in men is a counter-reaction to their own unwanted attraction to other men has its roots in psychoanalysis – where's it's considered a psychodynamic defence – and is possibly supported by anecdotal evidence, most recently in reports that the perpetrator of the horrific homophobic massacre at an Orlando gay club was himself gay.

Postpartum depression--a household term since actress Brooke Shields went public in 2005 about her struggle with it--is indeed serious. But depression that begins before or during pregnancy is often more severe because it lasts longer and usually goes undetected until the doctor screens for it after the birth of the baby.

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 »

Go ahead, sketch a face on your note paper. Use a photo of someone as a guide if you want.

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 […]

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 »

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 »
