Take a look at this astonishing (and adorable) video demonstrating how a baby acquires object permanence.
At 6 months old, the baby can see and reach for an object, but as soon as it is hidden, she doesn't seem to realize it's there. The baby is interested and excited by the objects, but when they're not visible, it's as if her memory has been wiped clean.
By 10 months, the phenomenon has vanished and the baby behaves like any older child would, clearly realizing that the book is hidden und........ Read more »

When traditional economics claimed that consumers can only gain from having more choice, the supermarkets listened - just look at the explosion in breakfast cereal offerings! But psychology has gone and complicated things by showing that more choice can often leave people feeling less satisfied and less likely to make a purchase.Consider the seminal paper by Iyengar and Lepper (pdf) that showed 30 per cent of participants offered a choice of 6 jams bought one, compared with just 3 per cent of pa........

Harold L Doherty, an autism advocate and parent of a child with autism, has commented on the limited amount of research conducted with kids with severe autism. Although this is an empirical question, and I have not seen data confirming this possible trend, Mr. Doherty is most likely right, in that it appears that children with severe autism are underrepresented in today's published research.

Ok, I was GOING to post this last night. But Sci's laptop had epic internet fail. Hopefully it will work again anon. As it is, you're getting your post late. Sci was going to do something for April 1. Too late now!
In the meantime, let's talk about flushing. Being female, Sci had a certain amount of exposure to things like makeup growing up, and the one thing I could never understand was this:

The correlation between atheism and IQ is being talked about again because the study I blogged about last year (by Richard Lynn) has just been published. PZ Myers simply dismisses it - there's no correlation at all, he thinks (although he hasn't read the paper).But there's another, rather more interesting paper out on the topic. It goes further than Lynn by actually trying to take into account some of the other factors that could explain the correlation.The author, Satoshi Kanazawa, is an evolut........ Read more »
Take another look at this picture of the Rokeby Venus from last week's post on mirrors in art:
Now, imagine you're actually in the room with Venus, as depicted in this painting. You suspend your astonishment long enough to conduct a quick test of the principle of how a flat mirror works. Consider what would happen to Venus' face in the mirror as you approach it. As you walk towards the mirror, would the proportion of the reflection taken up by Venus's face increase or decrease? In the paintin........ Read more »

Anxiety sensitivity (AS) is basically the fear of feeling anxious, or feeling anxiety-related symptoms. Typically, when people are fearful of their own symptoms of anxiety, they’ll work to avoid getting into situations where they may experience these symptoms. AS has been shown to be a predisposing factor in some anxiety-related disorders such as panic attacks. [...]... Read more »

Last week I discussed a study showing that kids with low functioning autism identify noses better when these are presented upside down than when presented upright. In the context of that study, the authors suggested that these kids have an aversion to examining eyes directly and tend to focus on parts of the face away from the eyes.This week a group of researchers from Yale University published a

Remember that, in my first post (1), I pointed out that the primary outcome measure for the study was useless? In this second paper (2), the authors admit how unimportant their primary measure was, "...its extensive secondary physical and psychosocial consequences (alcohol dependence) are what make the burden of the disease so devastating. This realization is enshrined in practice in that no commonly used diagnostic scheme for alcoholism or alcohol dependence (i.e., DSM & ICD) includes a qua........ Read more »

Often, if a film features two characters who look vaguely similar - for instance both are tall, dark-haired, middle-aged men - I will find myself confusing the two, as I struggle to form a distinct impression of each of their faces. Maybe it's to do with the fact I'm male. New research by Ryan McBain has built on previous, more equivocal studies by showing that women are better than men at spotting a face in a display, and better at distinguishing between faces.In an initial experiment, 35 women........

Deliberately using imagery, attention diversion and mindfulness to cope with pain is not something new. It’s great though, to find that it has some very positive results when studied in a formal clinical research setting.

A number of studies have shown that some parents of children with autism show mild autistic tendencies. This has been called the 'broader autism phenotype'. However, less is known as to whether such phenomenon also affects typically developing brothers and sisters of children with autism. That is, are non-affected siblings of kids with autism free developmental problems or do they show a broader

In the Netherlands (and I’m sure there are versions of it in the UK and the US as well) there is a weekly radio show containing a returning item in which music experts are asked to compare and judge two or three CD recordings of the same piece, without knowing who the musicians are. They have to guess the performers and describe why they do (or don’t) like that particular performance.How well would you do in such a test? The common hypothesis is that experts do this much better, e.g. under t........ Read more »

You wouldn't know it from the claims of companies like No Lie MRI, but we're a long way off being able to use brain scans to detect reliably whether a person is lying or not. Nonetheless, cognitive psychologists are busy beavering away in the background, testing the ways that brain activity varies when people lie compared with when they tell the truth. One such study has just been published, claiming to be the first to investigate deception in the context of face recognition.Sujeeta Bhatt and co........ Read more »
Last week I spent a little time looking at activity regulation, and especially looking at over-activity or persistence, rather than the usual under-activity or avoidance pattern.

It's unbelievable what's uncovered sometimes. A recent survey of British psychologists and psychiatrists has uncovered that a sizeable amount have attempted to "convert" homosexual patients or clients to heterosexual orientations!
It's a well-known axiom that (biological) homosexuality is an orientation that cannot be changed, what to speak of the scientific consensus on the matter, and what do you think might happen if any such changes are encouraged? Psychological h........ Read more »

Numerous studies have attempted to correlate general intelligence with different anatomical measures. (You might even argue that the phrenologists were working in this vein.) Likewise many studies have attempted to relate intelligence to the function of different brain regions -- using techniques like fMRI or PET scanning. However, relatively few studies have attempted to correlate general intelligence with anatomical features of particular brains regions.
This is important because we know........ Read more »
