Imitation and Social Cognition (III): Man’s best friend

by Michael in A Replicated Typo 2.0


Tweet


In my two previous posts (here and here) about imitation and social cognition I wrote about experiments which showed that

1)  young children tend to imitate both the necessary as well as the unnecessary actions when shown how to get at a reward, whereas wild chimpanzees only imitate the necessary actions.

And that

2) both 14-month old human infants . . . → Read More: Imitation and Social Cognition (III): Man’s best friend... Read more »

Willpower and Reward Myopia

by Shaheen Lakhan in Brain Blogger

Consider the phenomenon of swearing off of big desserts for the sake of losing weight. Have you ever noticed how much less important that value is (or how it does a disappearing act) when it's time for dessert?... Read more »

Where is home?

by Ingrid Piller in Language on the Move

Many of the people close to my heart are transnationals such as myself. Belonging is a frequently discussed topic in my circles, and often a topic that is surrounded by considerable angst. Where do we belong? Is it really worth … Continue reading →... Read more »

Is the yellowstone caldera safe?

by Greg Laden in Greg Laden's Blog

Not long after Yellowstone Park was officially created, a small group of campers were killed by Nez Pers Indians on the run from US troops1. More recently, the last time I was in the area, a ranger was killed by a Grizzly Bear (so was his horse) on the edge of the park. A quick glance at my sister's newspaper archives (Lightning Fingers Liz a.k.a. Caldera Girl has been running newspapers in the region for nearly forty years) shows a distinctive pattern of danger in the Caldera, mainly in relat........ Read more »

Fusion for the Future: NIF

by The Astronomist in The Astronomist.

Fusion is only 50 years away and it will solve all of the worlds energy problems. That is the good news. The bad news is that it has been 50 years away for the last 50 years. If that situation is maddening to you then you are not alone. Leonardo Mascheroni, a retired Los Alamos National Laboratory physicist, wanted funding to build a colossal laser for producing energy from fusion and was willing to trade the United States' nuclear weapons secrets to realize his dream. Mascheroni was recently in........ Read more »

Turn down your thermostat to lose weight, suggests new study! (Dripping with sarcasm)

by Peter Janiszewski, Ph.D. in Obesity Panacea

So now that I’ve got your attention, let me tell you off the bat that making your home cold is not the most viable weight-loss strategy  -  despite what the headlines might suggest.
A recent study was published in the International Journal of Obesity which looked at a number of uncommonly explored potential contributors to obesity, including sleep restriction, house temperature, television watching, consumption of restaurant meals , use of air conditioning and use of antidepressant/antipsych........

The many magnificent subspecies of Argali

by Darren Naish in Tetrapod Zoology



Back in May 2007 I wrote a few articles about the world's wild sheep (Welcome.... to the world of sheep and Return.... to the world of sheep). If you're here for the dinosaurs, pterosaurs, pygmy mammoths and lake monster photos, you might regard wild sheep as pretty boring animals. But they're clearly not - they're incredible and spectacular in appearance, often surprisingly large, and they live wild lives in beautiful, wild locations. And they're highly popular, and the source of great fascin........ Read more »

Flowers, Pine Cones and Dinosaurs

by Brian Switek in Dinosaur Tracking

When we think about the Mesozoic world, dinosaurs often dominate our attention. They are the stars of countless museum displays and restorations, and everything else about their world just seems like window dressing. When visitors to Yale’s Peabody Museum look at Rudolph Zallinger’s beautiful (if outdated) “Age of Reptiles” mural, their attention is drawn to [...]... Read more »

Pot use and early psychosis: Does smoking marijuana increase the risk for schizophrenia?

by Nestor Lopez-Duran PhD in Child-Psych

Just wanted to share some quick thoughts on a large meta-analysis that was recently published in the prestigious Archives of General Psychiatry. In this publication, the authors reviewed all previous studies that have examined the association between substance use (Cannabis, Alcohol, and other substances) and the onset of psychotic disorders (such as schizophrenia). Although the [...]

So, how do you know when a vaccine is safe?

by Connor Bamford in The Rule of 6ix



How can you tell how safe a vaccine is?

Mumps, a highly infectious viral disease, has been largely eradicated in the developed world following the introduction of a highly effective live-attenuated vaccine. Highlighted by well-publicized outbreaks in the U.S and U.K, the number of cases, however, has risen causing worldwide alarm. The reasons for this re-emergence have yet to be fully elucidated but most likely are due to a number of factors, including waning immunity and poor vaccine cover........ Read more »

Will Losing Weight Make You Less Depressed?

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Regular readers will appreciate the importance of mood as a driver of ingestive behaviour. While typically depression is associated with a loss of appetite, atypical depression can lead to increased cravings for “comfort” foods, especially those high in sugar and fat.
Depression is also well recognized as a major barrier to weight loss in that individuals [...]... Read more »

You truly never know what you’ll need in court. The unexpected happens. We are here to give you an edge. Back in May, 2010 we wrote about how people tend to remember things more when they are placed to their left.

The Decline And Fall of Effects In Science

by Neuroskeptic in Neuroskeptic

Nature has a piece called Unpublished results hide the decline effect.This refers to the fact that many scientific findings which seem to indicate something big is happening, end up getting smaller and smaller as more people try to replicate them until they, eventually, may vanish entirely.The Last Psychiatrist's take is that "The Decline Effect" just represents sloppy thinking, treating different things as if they were all instances of The One True Phenomenon. Someone does a study about somethi........ Read more »

The cycle that ends the cycle

by Becky in It Takes 30

Senescence is the sign of a cell that’s given up.  Cells that have reached the “Hayflick Limit” — usually 40-60 divisions for non-transformed cells in cell culture — can no longer divide; this observation, which was a surprise at the time, led to the coining of the term cellular senescence. One reason that cells become [...]... Read more »

Brazilians, more European than not?

by Razib Khan in Gene Expression


Credit: Dragon Horse
The Pith: Brazil is often portrayed as the second largest black nation in the world, after Nigeria. But it turns out that the majority of the ancestors for non-white Brazilians is European.
One of the more popular sources of search engine traffic to this website has to do with the population genomics of Latin America. For example, my post showing that Argentina is not quite as European a country as it likes to consider itself is regularly cited in online arguments (people........ Read more »

Testosterone and Estrogen Have Opposite Effects on a Gene Thought to be Underexpressed in Autism

This gene is thought to be underexpressed in autistic people, based on two studies that I also discuss in the post.... Read more »

A Promising New Drug for Cystic Fibrosis

by Daniel Koboldt in Massgenomics

Today I got a call from a patient with cystic fibrosis, asking if I knew much about a specific mutation called 2184-del-A. It was a striking conversation, particularly because I tend to envision about infants and young children when I think about CF, and this woman was clearly an adult, a working professional, who had [...]...
