A new study of the genetic origins of dyslexia and other learning disabilities could allow for earlier diagnoses and more successful interventions, according to researchers at Yale School of Medicine. Many students now are not diagnosed until high school, at which point treatments are less effective.... Read more »

s social psychology in a crisis? Nobel Laureate Daniel Kahneman sparked an online (and laboratory) dustup last fall when he accused certain social psychologists of undermining the credibility of their field. At issue is whether certain experiments can be replicated. Kahneman says they should be. Other scientists have reported that certain popular results can’t. And that’s a problem.... Read more »

For the past 70 years or so, crime has mainly been explained through socio-economic factors such as housing or level of education. Currently the focus has shifted more to neuroscience and biology – and the idea that a chemical imbalance might also cause someone to be more violent or prone to criminal behavior.... Read more »
Positive emotion has long been recognised as facilitating creativity, through broadening thinking and allowing exploratory mental wandering. Conversely, high negative emotion tends to lead to narrow focus on salient, possibly threatening environmental features (such as an impending deadline or difficult conversation), which has lead many to discount it as an impediment to creativity. But recent research suggests that prior states of negative emotion can improve subsequent creative activity.The p........ Read more »
The study of the DNA of vira is becoming increasingly popular to understand how it affected people in the past, how the disease evolved, and whether its modern equivalents are similar. Genomic studies of different variations of the plague have been in the news over the past few years. A recent study of the Justinian … Continue reading »... Read more »

Is a laboratory test or brain scanning method for diagnosing psychiatric disorders right around the corner? How about a test to choose the best method of treatment? Many labs around the world are working to solve these problems, but we don't yet have such diagnostic procedures (despite what some might claim). A new study by McGrath et al. (2013) might be a step in that direction, but the results are very preliminary and await further validation.The principal investigator of that study is Dr. Hel........ Read more »

I've been doing this whole parenting thing for almost three months now and it has been simultaneously gratifying, terrifying, exhausting, and fascinating. One thing I haven't been doing is sleeping, and because of this I have had a lot of time to read up on some neat research on new parents. Last time I wrote about how parenting reduces Testosterone in men. Today I blog about the relationship between parenting and immune function.
Can parenting boost the immune system?

In the year 2006 'google' was officially declared a verb in Oxford Dictionary and Merriam Webster. But startups have not given up on building search engines. That same year Facebook opened its doors to users over the age of 13, preparing for exponential growth spurt. The list of startups working on yet another social network and lining up to present their sites at Silicon Valley New Tech Meetup kept growing too. And so were the crowds attending the meetups - as everybody wanted to see the next ........ Read more »

Blinkers and non-blinkers have individual differences in selective attention and the ability of the non-blinkers to sense the targets presented in close temporal succession might be due to fairly quicker and exact target selection process.
Many people are unable to respond to the second target when presented in close time to the first (200-500 ms interval) and this phenomenon is known as attentional blink (AB). This concept is in r........ Read more »

When people think of mental problems related to body image, often the first thing that comes to mind is the thin figure associated with anorexia. Body dysmorphic disorder is less well known, but has around five times the prevalence of anorexia (about 2% of the population), and a high level of psychological impairment. It’s a mental disorder where the main symptom is excessive fear of looking ugly or disfigured. Central to the diagnosis is the fact that the person actually looks normal.... Read more »
