Rehearsal during sleep can increase your potential of long-term memory
by Usman Paracha in SayPeople
Main point:
Researchers found that memory rehearsal during sleep can help you to remember things for a long time.
Journal:
Journal of Neuroscience
Study Further:
In this study, researchers worked with the volunteers and asked them to remember the locations of the objects on a computer screen. A value given to each object informed participants how much money they could make if they remembered it later on the test.
"The pay-off was much higher for some of the objects than fo........ Read more »

Another Penis Story: Size Matters, Up to a Point
by Andrew Porterfield in United Academics
While females are attracted to larger penises, their interest only extends to a degree and penis size isn’t the only trait that concerns them, a new Australian study shows. Although this finding grabbed a lot of headlines, the research also provided insight into how genitalia can evolve, even without having offspring.... Read more »

Which jurors most “feel” your client’s pain?
by Doug Keene in The Jury Room
This is an intriguing question with a pretty straightforward answer. But if you are assuming the answer is “women”, you are only partially correct. Researchers from Michigan, New York and North Carolina investigated the relationship of age and empathy in three large samples of American adults who ranged in age from 18 to 90 years. [...]

Anxiously attached people are ace at poker and lie detection
by Christian Jarrett in BPS Research Digest
People who worry habitually about separation and abandonment - the "anxiously attached" - tend to be highly skilled at lie detection, an attribute that means they excel at poker. That's according to Tsachi Ein-Dor and Adi Perry whose new findings build on their theory that anxiously attached people are natural sentinels - highly sensitive to threats in the environment, including, this new research suggests, social threats.
Across a pair of initial studies, dozens of men and women an........ Read more »

Surviving Sandy: Staying Put in Far Rockaway
by Elke Weesjes in United Academics
Hurricane Sandy churned across the Caribbean and up the eastern seaboard of the U.S. in late October of 2012, leaving a path of death and destruction in its wake. This article focuses on the decision making among some of those who stayed behind in the storm—and how we might use that information to better prepare for the disasters of the future.... Read more »

Mathematical Turing test: Readable proofs from your computer
by Artem Kaznatcheev in Evolutionary Games Group
We have previously discussed the finicky task of defining intelligence, but surely being able to do math qualifies? Even if the importance of mathematics in science is questioned by people as notable as E.O. Wilson, surely nobody questions it as an intelligent activity? Mathematical reasoning is not necessary for intelligence, but surely it is sufficient? [...]... Read more »

What’s The Point of Bingeing and Purging? And Why Can’t You Just Stop?
by Tetyana Pekar in Science of Eating Disorders
I defended my MSc degree on Tuesday and I’m not going to lie: I was pretty symptomatic with bulimia in the days prior to my defence. As I was explaining to my boyfriend, the anxiety-reducing effects of purging are so powerful, and the compulsion to binge and purge (when I’m stressed/anxious/”not okay”) is so strong that it is much easier to do it, get it over with, and continue working (in a much calmer state).
I’ve mentioned before, for me, purging is very anxiety-........ Read more »

How Pharmaceutical Ads Distort Healthcare Markets
by Eric Horowitz in peer-reviewed by my neurons
It probably doesn’t strike you as strange to see advertisements for prescription drugs. By now, everybody know that you should “talk to your doctor about Levitra” while “doing more with Lipitor” and getting “Claritin clear.” But if you think about it, it’s strange for an actor being paid by a pharmaceutical company to tell you [...]...

Fatigue severity and serum leptin levels in chronic fatigue syndrome
by Paul Whiteley in Questioning Answers
In the very complicated world of medical research and science, the days of one chemical, one metabolite, or one gene driving and sustaining ill-health and particular diseases or conditions seem to be all but long past. Sure, there are conditions which on the surface seem to be driven by only one factor, but more often than not is the realisation that we humans are very complicated creatures indeed.Leptin @ Wikipedia I was therefore interested to read the paper by Elizabeth Stringer and col........

The Man With Uncrossed Eyes
by Neuroskeptic in Neuroskeptic_Discover
“GB” is a 28 year old man with a curious condition: his optic nerves are in the wrong place. Most people have an optic chiasm, a crossroads where half of the signals from each eye cross over the midline, in such a way that each half of the brain gets information from one side of [...]...

Egalitarians’ dilemma and the cognitive cost of ethnocentrism
by Artem Kaznatcheev in Evolutionary Games Group
Ethnocentrism (or contingent altruism) can be viewed as one of many mechanisms for enabling cooperation. The agents are augmented with a hereditary tag and the strategy space is extended from just cooperation/defection to behaviour that can be contingent on if the diad share or differ in their tag. The tags and strategy are not inherently [...]... Read more »

Why Overconfidence Occurs and How to Overcome It
by Winston Sieck in Head Smart
Overconfidence happens to all of us. Ever have a plan that just couldn’t go wrong? And then you get a kick in the butt. Ever know that something must be true, only to find out later that you had it backwards? Overconfidence is when you think you are more likely to be right than you [...]... Read more »

Stereotypes happen all the time if you are neither pale nor male
by Rita Handrich in The Jury Room
The title of this blog post comes from a post by Ainissa Ramirez on gender and racial bias in the workplace. It’s a lovely turn of phrase even for such an ugly thing. We might think of the science fields as being more neutral and unbiased. I mean, it is science, right? Not so much. Researchers [...]

ADHD at work: helping others over getting the task done?
by Alex Fradera in BPS Occupational Digest
New research looking at how ADHD affects performance at work. The condition has a high prevalance, with 4.4% of American adults estimated to have it, and a body of research suggests that it can influence work outcomes like productivity, work conflict and turnover. Jonathon Halbesleben, Anthony Wheeler, and Kristen Shanine have just published research suggesting that ADHD may have consequences via two routes: encouraging behaviours that are not pointed at intended goals, and eroding the benefits ........

ADHD and a sunny disposition
by Paul Whiteley in Questioning Answers
'Light it up blue' is probably a familiar phrase to many of those involved with autism as being the message championed by Autism Speaks on World Autism Awareness Day (2 April). The intention is noble enough: to bring autism to the attention of the world at large and importantly, keep their attention and resources focused on autism. I might add that awareness is one thing; actually 'doing something about autism' - whether that means improving prospects or modifying the course of autism or just le........ Read more »

A new cure for insomnia?
by Shelly Fan in Neurorexia
Many a nights I’ve tossed and turned, willing my brain to STFU and let me sleep. I’m not alone in this battle. 10-15% of adults suffer from insomnia, and up to a third take prescription sleeping pills to bring on the snooze – for a heavy cognitive price. Current sleeping drugs, such as Ambien and [...]... Read more »
