Empathy or the ability to appreciate someone else’s emotions and express this emotional awareness is a capacity that differs amongst individuals.
Cognitive empathy refers to imaginatively understanding another person’s thoughts, feelings and actions. Emotional empathy is feeling the emotion of another person, but maintaining a compassionate, other-focused perspective
Cognitive empathy can be tested with facial expression recognition. [...]

You all may remember that Sci's recent posts have focused on eating, overeating, and dopamine. Today, Sci continues this trend. Honestly, she couldn't stop thinking about it. How is overeating like addiction? How is it different? And so she began to look up a bunch of papers on binge eating and dopamine.

Creativity is certainly different from intelligence; it is usually gauged as the ability to make novel and useful unique contributions to a field. Creativity itself is not a unified construct but can be broken into convergent creativity (involving more focused approach) and divergent creativity (involving more widening and loosening of More >Rating: 0.0/10 (0 votes cast)

A red panda (Ailurus fulgens, left, photographed at the Bronx Zoo) and a giant panda (Ailuropoda melanoleuca, right, photographed at the National Zoo).
As the paleontologist Stephen Jay Gould so astutely pointed out in one of his most famous essays, the thumbs of giant pandas (Ailuropoda melanoleuca) are nothing at all like the large digits on our own hands. Their accessory "thumbs", visible on the surface as a differentiated part of the pad on the "palm" of the hand, are modified sesamoid........ Read more »

Although we are most familiar with the circadian rhythm from its effects on our physiological state, the roots of the phenomenon lie in the molecular biology of individual cells. The circadian rhythm is the result of a transcriptional control system that regulates the levels of many different proteins in the cell with the passing of time. Not all of the proteins subject to this control have yet been catalogued, and as a result some surprising effects are still being discovered. A recent article ........ Read more »

Can environmental conditions during early development shape individuals phenotypes so they become more adaptive to the conditions they are likely to encounter later in life? Such phenotypic plasticity could provide organisms with the potential to respond effectively to environmental change. One area where such plasticity would be important would be in an animals sensory capabilities. Animals extract information from the environment using a number of sensory systems, and this information guides t........ Read more »

Even though their preferred range places them in proximity to the Atlantic Ocean and the Gulf of Mexico, the conquest of marine ecosystems by the cottonmouths has been - as it has with most aquatically inclined reptiles - blockaded.

WILLIAMS Syndrome (WS) is a rare neurodevelopmental disorder caused by the deletion of about 28 genes from the long arm of chromosome 7. It is characterized by mild to moderate mental retardation and "elfin" facial features. Most strikingly, individuals with WS exhibit highly gregarious social behaviour: they approach strangers readily and indiscriminately, behaving as if everybody were their friend. And, according to a study published today in the journal Current Biology, they are the only know........ Read more »

One of the difficulties doctors face when prescribing antidepressants is that they're unpredictable.One person might do well on a certain drug, but the next person might get no benefit from the exact same pills. Finding the right drug for each patient is often a matter of trying different ones until one works.So a genetic test to work out whether a certain drug will help a particular person would be really useful. Not to mention really profitable for whoever patented it. Three recent papers, pub........ Read more »

Seeking the hidden causes of behavior, some scientists work on the scale of brain regions and neurons, searching inside people's heads. Others work on the scale of crowds, neighborhoods and nations, seeking hidden patterns in the way multitudes behave. What's unusual about this paper in PLoS One is that it combines both those perspectives: Mehdi Moussaïd and his co-authors have worked out the physical effects of a psychological motivation. That gave them a new way to predict how people wa........ Read more »

I'm teaching a junior/senior level elective this term on quantum mechanics. We're using Townsend's A Modern Approach to Quantum Mechanics, which starts with spin-1/2 and develops the whole theory in terms of state vectors and matrices. This is kind of an uneasy fit for me, as I'm very much a swashbuckling experimentalist, and not as comfortable with formal mathematics.

It is widely assumed that 5 participants suffice for usability testing. In this study, 60 users were tested and random sets of 5 or more were sampled from the whole, to demonstrate the risks of using only 5 participants and the benefits of using more. Some of the randomly selected sets of 5 participants found 99% of the problems; other sets found only 55%. With 10 users, the lowest percentage of problems re-vealed by any one set was increased to 80%, and with 20 users, to 95%. [Faulkner, 2003]... Read more »
