Main Point: Researchers found that the children who avoid scary situations have more anxiety disorders.
Journal: Behavior Therapy
In this study, researchers worked on more than 800 children in the age range of 7 to 18. Researchers developed two questionnaire reports, i.e. the Children’s Avoidance Measure Parent Report and the Children’s Avoidance Measure Self Report, where they asked the children’s avoidance tendencies, such as, in addressing parents, ........

How does your dog compare to a toddler? Recent animal research is comparing the abilities of dogs with young humans. A brand new study by Márta Gácsi et al in Hungary investigates whether dogs have the same response as infants to a test called the Strange Situation.In humans, attachment theory explains how children need to develop a strong attachment to at least one caregiver. If they don’t, their social and emotional development will be disrupted. As infants begin to crawl, the caregiver is........ Read more »

Actually the title of this post is a bit of a misnomer.I'm not really asking readers to say 'no' to sapropterin, otherwise known as tetrahydrobiopterin or BH4, for autism as if it were some kind of Zammo-esque drugs in the toilet scenario (note: for anyone born post-Grange Hill golden era or for my non-UK readers, you might want to follow this link to see what I'm going on about). But neither am I saying yes, as per my prime directive on this blog: no medical or clinical advice given or intended........ Read more »

Broad generalizations are often made in popular psychology about one side or the other having characteristic labels, such as "logical" for the left side or "creative" for the right. These labels need to be treated carefully; although a lateral dominance is measurable, both hemispheres contribute to both kinds of processes.In psychology and neurobiology, the theory is based on what is known as the lateralization of brain function. So does one side of the brain really control specific functions? A........ Read more »

In the last issue of the Human Resource Management Journal, Dorien Kooij and colleagues investigate how general HR practices might have differential effects for younger and older employees. Given the ageing workforces prevelant in the West, it's an increasingly relevant issue.800 respondents to a much larger survey were randomly selected to form eight equally sized age groups, ranging from those below 20 to an over-50 group. Participants reported their experiences of HR practices that could infl........ Read more »

Culture is a powerful thing.

Brain researchers are increasingly focused on whether our brains are red or blue–as in Democrat or Republican. And there appears to actually be something to it.

The day before mixed martial artists compete in the Ultimate Fighting Championships (UFC), they pose with each other in a staged face-off. A new study has analysed photographs taken at dozens of these pre-fight encounters and found that competitors who smile are more likely to lose the match the next day (pdf via author website).

Because it is hard to get a paper published in a high-impact journal, it is often assumed that such papers are of particularly high quality. In practice, however, these journals focus more on newsworthiness of findings than methodological rigour, and, as Tressoldi et al (2013) have shown, their standards of statistical reporting can be low. This point is illustrated by a recent paper in Current Biology entitled "Action video games make dyslexic children read better." This study was ser........ Read more »
