Psychology graduate student & educator. Marionette maker, rubber stamp carver, amateur seamstress. Mostly, I ride my bicycle, drink cups of coffee, read, intellectualize, and am redundant - even when I feel witty. This space is for displaying lovely, amusing or enlightening images and concepts I come across.
Solid science sometimes devolves into pseudoscience, but the imprimatur of being science nevertheless may remain. No better example of this is the popular “left brain/right brain” narrative about the specializations of the cerebral hemispheres. According to this narrative, the left hemisphere is logical, analytic, and linguistic whereas the right is intuitive, creative, and perceptual. Moreover, each of us purportedly relies primarily on one half-brain, making us “left-brain thinkers” or “right-brain thinkers.”
This characterization is misguided, and it’s time to put it to rest.
Two major problems can be identified at the onset:
First, the idea that each of us relies primarily on one or the other hemisphere is not empirically justifiable. The evidence indicates that each of us uses all of our brain, not primarily one side or the other. The brain is a single, interactive system, with the parts working in concert to accomplish a given task.
Second, the functions of the two hemispheres have been mischaracterized. Without question, the two hemispheres engage in some different kinds of information processing. For example, the left preferentially processes details of objects we see whereas the right preferentially processes the overall shape of objects we see; the left preferentially processes syntax (the literal meaning), the right pragmatics (the indirect or implied meaning) and so forth. Our two hemispheres are not like our two lungs: One is not a “spare” for the other, redundant in function. But none of these well-documented hemispheric differences come close to what’s described in the popular narrative.
It is time to move past the popular but incorrect left brain/right brain narrative."

Psychologist Stephen M. Kosslyn, director of Stanford’s Center for Advanced Study in the Behavioral Sciences, is among the 176 prominent scientists who answered this year’s Edge Question: ”What scientific idea is ready for retirement?”
Also see this animated case against the left/right brain divide, then look back on previous compendiums of famous scientists’ answers to the annual Edge Questions, including “What scientific concept will improve everybody’s cognitive toolkit?” (2012) and “What is your favorite deep, elegant, or beautiful explanation?” (2013).

- 22 the number of people—mostly young children—that have contracted polio in Syria, according to the World Health Organization. It’d be the first outbreak in the country in 14 years, and as many as 100,000 children are susceptible to the disease in the highly-contested Deir Ezzor province alone. Due to the poor living conditions, refugees are also susceptible to the disease as well. source

Ian Stevenson shows that art can be made out of the most unconventional things and still put a smile on your face. Through his fun typography and scribbles, he adds a dash of humor to the streets by giving life to abandoned objects, garbage bins and random walls.
