Our 2nd edition of Introductory and my 3rd edition of Behavioral Neuroscience

Here is what we are reading today:

“A study by Melissa Koenig of the University of Minnesota and colleagues shows that by the time they reach the age of seven, children can think strategically, in an adult manner. The researchers found that when playing games, children older than 6.5 use strategies comparable to those used by adults. The research appears in the Proceedings of the National Academy of Sciences.”

“”In a recent study by psychologists Colin Camerer and Tetsuro Matsuzawa, chimps and humans played a strategy game – and unexpectedly, the chimps outplayed the humans.”

“”Like people, each animal has unique experiences as it goes through its life. And we suspect that these life experiences can alter the expression of genes, and as a result, affect an animal’s susceptibility to stress,” says senior author Bruce McEwen, Alfred E. Mirsky Professor and head of the Harold and Margaret Milliken Hatch Laboratory of Neuroendocrinology. “We have taken an important step toward explaining the molecular origins of this stress gap by showing that inbred mice react differently to stress, with some developing behaviors that resemble anxiety and depression, and others remaining resilient.””

“Sharing regular family meals with children may help protect them from the effects of cyberbullying, according to a study by McGill professor Frank Elgar, Institute for Health and Social Policy. Because family meal times represent social support and exchanges in the home that benefit adolescents’ well-being, Elgar suggests that this family contact and communication can also reduce some of the distressing effects of cyberbullying.”

“”It is the last nail in the coffin for the hypothesis that Neanderthals were cognitively inferior to modern humans,” said Paul Tacon, an expert in rock art at Australia’s Griffith University. Tacon, who was not involved in the study, said the research showed that the engravings were made with great effort for ritual purposes, to communicate with others, or both.

“We will never know the meaning the design held for the maker or the Neanderthals who inhabited the cave but the fact that they were marking their territory in this way before modern humans arrived in the region has huge implications for debates about what it is to be human and the origin of art,” said Tacon.”

“”Our work has shown that two types of first-order tactile neurons that supply thesensitive skin at our fingertips not only signal information about when and how intensely an object is touched, but also information about the touched object’s shape” says Andrew Pruszynski, who is one of the researchers behind the study.

The study also shows that the sensitivity of individual neurons to the shape of an object depends on the layout of the neuron’s highly-sensitive zones in the skin.”

“It looks like environmental enrichment is a way to improve the treatment of children with autism and perhaps other mental disorders. Moreover, the therapy can be done at almost no cost and with no need for any kind of expertise. But the really big idea is that there may be no reason to wait until you or your child has a neurological disorder to enrich your mind. We are currently working to evaluate the notion that it may be possible to use this approach to maximize our mind’s capabilities throughout our lifetime.”

I read the article “Genes don’t just influence your IQ” and found it to be quite interesting. Although I was already aware that a lot of environmental factors affect the way you succeed in school, I was not aware of the fact that the specific genes affecting motivation and other traits shape your intelligence. It was also intriguing to find that the study done at King’s College London was one of the first to not solely focus on IQ, but also IQ with other hereditary traits. One of my favorite statements that I read from this article was how these kinds of studies can improve childhood education and lead to a more promising educational system.
