There is considerable interest in methods to speed up the effects of treatments for obsessive-compulsive disorder (OCD). Exposure and response prevention are key therapy interventions for OCD and these treatments have significant evidence-based support for effectiveness. A recent study examined whether the drug d-cycloserine can boost the effect of standard behavior therapy in OCD.D-cycloserine (DCS) is an antibiotic that appears to have cognitive effects that "facilitates fear extin........

Whether you're a dog, a cat, or a grad student who hasn't been home to shower for a few days, fleas are a major problem. They make skin itch. And NOTHING is worse than itchy skin.
Do you know WHERE the fleas are? Where they like to hang out and guard their little flea eggs? Where's the best place for a flea to get a decent night's sleep, or a delicious snack? These are important questions. Lucky for us, Hsu, Hsu, and Wu of the Department of Entomology at National Taiwan University ha........ Read more »

Monday’s briefs: Quick musing on child related research. One drawback of our culture of individualism is that it perpetuates the myth that we all have equal opportunities for success and that the only thing that is needed to achieve our goals is personal effort. The research on environmental contributions to academic and professional success strongly [...]... Read more »

When female chimps are nearing ovulation they display red on their bodies. Male chimps respond by masturbating and attempting to mount them. A new study claims we humans have moved on from this, but not a lot. Daniela Kayser's team found that when a lady wears red it prompts men to ask her more intimate questions and to sit closer to her. Surprisingly, this is the first time that the effect of colour on human sexual attraction behaviour has been studied. Past research has relied on asking partic........ Read more »
[Wherein our Hero considers the consequences of being Blonde. Notes for femme fatale bank-robbers...]

The tweet was referencing the degree of eye-contact men make with women who have different coloured hair. Though I couldn't find an article; (read more)

Do certain strains make you more forgetful?
Cannabis snobs have been known to argue endlessly about the quality of the highs produced by their favorite varietals: Northern Lights, Hawaiian Haze, White Widow, etc. Among dedicated potheads, debates about the effects of specific cannabis strains are often overheated, and, ultimately, kind of boring. It's a bit like listening to a discussion of whether the wine in question evinces a woody aftertaste or is, instead, redolent of elderberries. For mos........ Read more »

Using a narrative interview approach, Hallden and Christensson (2010)document the lived experiences of 10 young men in Sweden, whose girlfriends had procured an abortion.

Physiognomy is a debunked pseudo-science which claimed to describe characterisics solely from the face. The Illusrated Annuals of Phrenology & Physiognomy (1866) define Physiognomy as the "science of external forms in their relation to internal organisation and character," In 1886, Samuel Wells edited a paper suggesting characteristics of statesmen at the time, and what characteristics a statesman would need in order to be an effective man of the people. Wells (1889) initially maintains that ........ Read more »

At this time of year, as the weather turns colder and the nights become longer, one can't help but be thankful for our home. Some people never leave home, and some miss it terribly so. In contrast some don't, and do not care about their home, why is this? Today's article is concerned with the home, the importance of owning a home, and characteristics, even animal characteristics, that can be given to homeowners in order to understand what kind of home they might build and where.

The latest stop in the #PDEx tour is being hosted at Psychology Today by Sex at Dawn:There is no greater mystery in human evolution than the origins of our sexuality. Following the trail of clues available researchers have independently concluded that humans evolved through systems of monogamy, polygyny, as well as polyamory. However only one can be the culprit and, like a detective interrogating multiple suspects, the solution ultimately depends on which account you're willing to believe. Last ........ Read more »

Image via Wikipedia I have written previously about CNV’s and how de novo CNV’s have been recently shown to correlate with disorders like autism and schizophrenia.

The performance of young children on the 'mirror self-recognition test' varies hugely across cultures, a new study has shown. This is the test that involves surreptitiously putting a mark on a child's forehead and then seeing how they react when presented with their mirror image. Attempts by the child to touch or remove the mark are taken as a sign that he or she recognises themselves in the mirror. Studies in the West suggest that around half of all 18-month-olds pass the test, rising to 70 per........ Read more »

With the increase in electronic media in recent years, many parents are wondering what the effects might be of media use on the children--especially on their academic achievement. Many new media (e.g., computer games, websites, etc.) claim to have educational benefits, but in many cases they do seem to displace old-fashioned educational activities like reading books or playing board games. There is no scarcity of research on this topic, but a recent study in the journal Child Development caught ........ Read more »
