Verbal Ability and Face Processing in Autism

by Lindsay in Autist's Corner

Highlights counterintuitive results from De Wit et al. (2008)'s study of gaze patterns in autistic children: apparently, the greater the children's social and communication skills were, the less time they spent looking at the eyes of people shown interacting in video clips. This is odd because avoidance of eye contact is seen as a characteristic trait for autism, and to have kids who score as "less autistic" display this trait more strongly than kids who score as "more autistic" on measures of s........

Role of the anterior temporal lobe in semantic word retrieval

by Greg Hickok in Talking Brains

Lesion studies are making a come back and this is a good thing. fMRI is a good and valuable technique, but it absolutely needs to be balanced with other methods and lesion studies remain important in this respect. A new lesion study from Myrna Schwartz' group has recently appeared in the advance access section of the journal Brain. The study examines semantic word retrieval in aphasia using a picture naming task. For years this group has been doing fantastic psycholinguistically informed mod........ Read more »

What if you saw something that rocked your world ... and you didn't notice?

by Dave Munger in Cognitive Daily

If you're a regular reader of Cognitive Daily, you're relatively accustomed to seeing surprising things. Indeed, it's gotten to the point where you might even expect it. You've seen optical illusions and videos that baffle the imagination. Yet most participants in psychology research studies aren't aware of the many ways the mind can be "tricked." One of the most dramatic tricks, which we've discussed several times, is the phenomenon of Change Blindness. A........ Read more »

A very thorough explanation of psychosocial assessment for pain

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

I happened upon the Australian and New Zealand College of Anaesthetists website recently, and amongst some of the many resources found there, I located a very thorough description of psychosocial assessment for chronic pain. It’s a synthesis of many authors and resources and despite the orientation to medical assessment, and some of the discussion [...]... Read more »

The Sexy Stench of the Opposite Sex’s Genes

by Johnny in Ecographica

There are many ways to attract potential sexual partners. Some animals show-off with elaborately choreographed song and dance routines, others entice through the display of brilliant coloration, and yet others forego personal flare and solicit the opposite sex by bribing them with food or real-estate. Although the methods utilized to attract mates vary widely, the drive to reproduce is hard-wired in all of life. The genetic compliment held by each organism extends its reach into the external w........ Read more »

One year of ENCODE data

by Mary in OpenHelix

We’ve talked about the ENCODE data before, and you can see a number of entries about the project with the ENCODE tag.  But last week I came across the ENCODE paper in the Nucleic Acids Research Advanced Access collection, so it seemed like a good time to review some of the information about this project.
ENCODE stands for ENCyclopedia Of DNA Elements.  It is one of the big data projects wrangled by NHGRI.  There was a pilot phase project to explore the utility and methods of assessing in e........ Read more »

Misconceptions About the Battle in Seattle

by Eric Michael Johnson in The Primate Diaries

There are two fundamental misconceptions surrounding the protests against the World Trade Organization in Seattle ten years ago this week. One is that the protests represented a "riot" and that the majority of protesters were violent. The second is that the protests were counter-productive and actually hurt the cause of reform that would benefit poor countries trying to have their voices heard. Both of these are wrong and, in fact, are just the opposite. Read the rest of this post... | Read........ Read more »

Water intake and protein:carbohydrate ratio confound Drosophilia calorie restriction studies, implications?

by Colby in

Ja et al. (1) recently published the results of a study exploring how hydration and nutrient manipulation effects the results of calorie restriction in Drosophilia.
In non mammalian models, feeding rate is difficult to control, and often food is diluted with water without giving them a separate source of water.  Therefore, the specimens could be dehydrated [...]... Read more »

Life on Mars?!

On August 6, 1996 NASA announced that scientists at the Johnson Space Center had found evidence for life on Mars, and everybody went crazy.

"I wanted a new challenge" - Cross-cultural differences in workers' thoughts about their career changes

by Christian Jarrett in BPS Research Digest

It's not many generations ago that workers expected to have a job for life, most probably one that followed in the footsteps of their father, and his father before that. In many of today's richer societies, it's all different. Longer education and greater individual choice mixed with mergers, take-overs and bankruptcies mean that people's careers are typically punctuated by a series of distinct transitions or chapters. But how do people perceive these transitions and do such perceptions vary bet........ Read more »

Why Are There No Super Whales?

by Dr. M in Deep Sea News

The question is not why are whales big but why are whales not bigger?  The blue whales reached weights of 150 tons prewhaling.  To appreciate how massive a blue whale is, consider it would take 15 school buses, around 10 tons in weight to equal one of these marine mammals.  Why are there no 250 [...]...

More model perils; parametrize this

by The Curious Wavefunction in The Curious Wavefunction

Now here's a very interesting review article that puts some of the pitfalls of models that I have mentioned on these pages in perspective. The article is by Jack Dunitz and his long-time colleague Angelo Gavezzotti. Dunitz is in my opinion one of the finest chemists and technical writers of the last half century and I have learnt a lot from his articles. Two that are on my "top 10" list are his article showing the entropic gain accrued by displacing water molecules in crystals and proteins (a ma........ Read more »

by Michael Slezak in Good, Bad, and Bogus

The Herald Sun, not exactly known for its high-quality science reporting, has come out with a cracker today about sex and its health benefits. It’s a wonderful mixture of very old news and the sensationalising of some very questionable results. But, its about sex so already in a few short hours its being tweeted like mad and dugg by hundreds of people. Let’s have a quick look at some of the claims in the article whcih range from the boring to the truly irresponsible.
