A recurring finding in psychology is that people tend to overestimate the strength of their future emotions, an error known as the "intensity bias". You imagine that failing your driving test will leave you in the depths of despair, for example, but actually when it happens, you don't really feel too bad – the examiner was mean, you were feeling tired, and anyway you've still got your mate's party to look forward to next weekend. In other words, the reason you overestimated the emotional impac........ Read more »

"Descriptive analyses indicated that prenatal exposure to maternal BPA [Bisphenol A] concentrations were related to higher levels of anxiety, depression, aggression, and hyperactivity in children. BPA exposure in childhood was associated with higher levels of anxiety, depression, hyperactivity, inattention, and conduct problems."That was the conclusion reached in the systematic review by Maede Ejaredar and colleagues , that provides one of two studies brought to the blogging ta........

Antarctic seabirds called skuas are so clever that they can recognize individual humans after seeing them only a few times. Some Korean researchers discovered this by messing with the birds' nests and then waiting to get attacked. They're either very brave or have never watched The Birds.
The study took place on Antarctica's King George Island. The animals here didn't evolve around humans. People have only been making appearances on the island since the 1950s or so. Today 10 countr........ Read more »
This view has been challenged by the University of Southampton researchers Constantine Sedikides and Tim Wildschut, who have spent the past decade studying the benefits of nostalgia. Not only do they disavow its disease status, they have conducted numerous studies which suggest that nostalgia can make us more creative, open-minded and charitable. The definition of nostalgia used by Sedikides and Wildschut as a "sentimental longing for one's past" is based on the contemporary usage........ Read more »

By guest blogger Sofia DelenivWe often want to know what’s driving other people’s actions. Does the politician who visited a refugee camp on the eve of elections truly care for the poverty-stricken? In reality of course, our mind reading skills are pretty limited and something as complex as an apparent act of altruism can disguise a huge diversity of motives. Most of the time, these motives remain entirely private to the individual – a driving force in a black box.For a new paper publ........ Read more »

Without trying to scaremonger, it is already well known that certain anti-psychotics potentially indicated for some of the more 'challenging behaviours' associated with conditions like autism for example, carry their own important side-effects. Risperidone, one of the more commonly used medicines, has quite an extensive list of possible side-effects, some of which have been previously mentioned on this blog (see here). Increased appetite and weight gain are some of the more commonly observed sid........ Read more »

When doing pretrial research we have occasionally had mock jurors show up who were inebriated or high (yes, even at 7:45am), hostile or disruptive, confused more than the average person or obviously hearing voices or responding to companions no one else could see. Yes. Occasionally people with obviously serious psychiatric disorders make it through the […]

I'd like to start by making one thing abundantly clear about today's post: I am not insinuating that self-injurious behaviour (SIB) accompanying autism is solely under genetic (or epigenetic) control.As I've discussed before on this blog, there are potentially many, many reasons why SIB under the umbrella of the so-called 'challenging behaviours' occurs (see here). As and when it does happen, the onus is on those significant others to turn detective before anyone immediately reaches for somethin........ Read more »

'The disrupted connectivity hypothesis of autism spectrum disorders: Time for the next phase in research' went the title of the paper by Roma Vasa and colleagues .Disrupted connectivity by the way, refers to the idea that "deficiencies in the way the brain coordinates and synchronizes activity amongst different regions may account for the clinical symptoms of ASD [autism spectrum disorders]."

In today’s lexicon, the term mental illness is used pretty widely. It can be used to describe someone suffering from depression, to PTSD, to even someone suicidal.

I'm a fan of the idea that the categorical labelling system currently used in psychiatric and psychological circles probably isn't fit for purpose these days. Y'know, the idea that compartmentalising people into diagnostic boxes with an overarching title whilst useful for general identity and statistical classification, does little to inform about individual experiences or the important cross-over in presentation between and across different labels. Don't even get me started on how the use of su........ Read more »

Just as people throughout history have been subject to prejudice and persecution because of their religious beliefs, recent evidence suggests that atheists today are discriminated against because of their lack of faith. For instance, in a 2012 study, nearly one in two atheists and agnostics reported having experienced discrimination at work, in the family and elsewhere. Another US study that asked respondents to imagine their children marrying people from different social groups found that parti........ Read more »

It was a clear case of a false alarm, toxoplasmosis, a parasite that infects mice and cats was thought to have an effect on humans. However, after a thorough review of the data it was off the hook, or so we thought. Individuals with a psychiatric disorder involving recurrent bouts of extreme, impulsive anger--road rage, for example--are more than twice as likely to have been exposed to a common parasite than healthy individuals with no psychiatric diagnosis.

Had Teresa Dzieweczynski chosen to publish her recent findings as an updated children's classic, rather than as a research paper, she could have titled it If You Give a Fish an Antidepressant. The book would probably be less charming than If You Give a Mouse a Cookie. But it would also be, unfortunately, more realistic. Our pharmaceuticals are steadily trickling into the homes of fish and other animals. And—as the hero of the original book could have told us, his house in disarray aft........ Read more »

When calling an ambulance, every second counts. So when an ambulance service in South Africa wanted to speed up their response time, who did they call? Psychologists, of course.Looking to reduce any obstacles that delayed operators from obtaining key facts from callers, Claire Penn at the University of the Witwatersrand and her colleagues initially expected language issues to be a big tripwire – the officially English-language service was based in South Africa’s Western Cape, where four in f........
