Right Brain, Left Brain? Scientists Debunk Popular Theory Maybe you're "right-brained": creative, artistic, an open-minded thinker who perceives things in subjective terms. Or perhaps you're more of a "left-brained" person, where you're analytical, good at tasks that require attention to detail, and more logically minded. It turns out, though, that this idea of "brained-ness" might be more of a figure of speech than anything, as researchers have found that these personality traits may not have anything to do with which side of the brain you use more. Researchers from the University of Utah found with brain imaging that people don't use the right sides of their brains any more than the left sides of their brains, or vice versa. "It's absolutely true that some brain functions occur in one or the other side of the brain. Anderson and his colleagues, who published their new study in the journal PLOS ONE, looked at brain scans from 1,011 people between ages 7 and 29.
How To Boost Brain Power and Memory Until just a few years ago, doctors believed that the brain stopped making new neural connections - meaning that the memory began to get irreversibly worse - when the body stopped developing, usually in the early 20s. And doctors knew that, like any other part of the body, neurons weaken as people age. Loss of brain function due to neural breakdown was assumed to be a normal, unavoidable part of aging. It turns out they were wrong. In the past few years, it has become clear that you can, in fact, make new neurons starting in your 20s and continuing well into old age. You can literally rewire the brain with new parts as the older parts wear out. There are lots of things you can do right now to preserve, protect and enhance your gray matter. 1Physical exercise A healthy body really does mean a healthy mind. Physical exercise may even help prevent Alzheimer's disease. 2Lifelong learning - your brain is a learning machine How can you challenge yourself? 3Mental stimulation 5Sleep & Nap
Anthropology Anthropology /ænθrɵˈpɒlədʒi/ is the study of humankind, past and present, that draws and builds upon knowledge from social and biological sciences, as well as the humanities and the natural sciences. Since the work of Franz Boas and Bronisław Malinowski in the late 19th and early 20th centuries, anthropology in Great Britain and the US has been distinguished from ethnology and from other social sciences by its emphasis on cross-cultural comparisons, long-term in-depth examination of context, and the importance it places on participant-observation or experiential immersion in the area of research. In those European countries that did not have overseas colonies, where ethnology (a term coined and defined by Adam F. Origin of the term The term anthropology originates from the Greek anthrōpos (ἄνθρωπος), "human being" (understood to mean humankind or humanity), and -λογία -logia, "study." Fields According to Clifford Geertz, Sociocultural Biological
- LifeEdited Force of habit: Stress hormones switch off areas of the brain for goal-directed behaviour Cognition psychologists at the Ruhr-Universität together with colleagues from the University Hospital Bergmannsheil (Prof. Dr. Martin Tegenthoff) have discovered why stressed persons are more likely to lapse back into habits than to behave goal-directed. The team of PD Dr. Two stress hormones in use In order to test the different stress hormones, the cognition psychologists used three substances – a placebo, the stress hormone hydrocortisone and yohimbine, which ensures that the stress hormone noradrenaline stays active longer. Goal-directed behaviour and habits investigated in the experiment In the experiment, all participants – both male and female – learned that they would receive cocoa or orange juice as a reward if they chose certain symbols on the computer. Combined effect of yohimbine and hydrocortisone As expected, volunteers who took yohimbine and hydrocortisone did not behave goal-directed but according to habit.
Kinesthetic learning Kinesthetic learning (also known as Tactile learning) is a learning style in which learning takes place by the student carrying out a physical activity, rather than listening to a lecture or watching a demonstration. People with a preference for kinesthetic learning are also commonly known as "do-ers". Tactile-kinesthetic learners make up about five percent of the population. The Fleming VAK/VARK model (one of the most common and widely used categorizations of the various types of learning styles) categorized learning styles as follows: History Kinesthetic intelligence was originally coupled with tactile abilities, and was defined and discussed in Howard Gardner's Frames Of Mind: The Theory of Multiple Intelligences. In his book, Gardner describes activities (such as dancing and performing surgery) as requiring great kinesthetic intelligence: using the body to create (or do) something.

Educational psychology Educational psychology is the study of human learning. The study of learning processes, both cognitive and affective, allows researchers to understand individual differences in behavior, personality, intellect, and self- concept. The field of educational psychology heavily relies on testing, measurement, assessment, evaluation, and training to enhance educational activities and learning processes. This can involve studying instructional processes within the classroom setting. Educational psychology can in part be understood through its relationship with other disciplines. It is informed primarily by psychology, bearing a relationship to that discipline analogous to the relationship between medicine and biology. The field of educational psychology involves the study of memory, conceptual processes, and individual differences (via cognitive psychology) in conceptualizing new strategies for learning processes in humans. History Early years Plato and Aristotle
Pareto efficiency Pareto efficiency, or Pareto optimality, is a state of allocation of resources in which it is impossible to make any one individual better off without making at least one individual worse off. The term is named after Vilfredo Pareto (1848–1923), an Italian economist who used the concept in his studies of economic efficiency and income distribution. The concept has applications in academic fields such as economics and engineering. For example, suppose there are two consumers A & B and only one resource X. Pareto efficiency is a minimal notion of efficiency and does not necessarily result in a socially desirable distribution of resources: it makes no statement about equality, or the overall well-being of a society. The notion of Pareto efficiency can also be applied to the selection of alternatives in engineering and similar fields. Pareto efficiency in short It is commonly accepted[by whom?] Weak Pareto efficiency Use in engineering for each i and
20 Amazing Facts About Your Brain The human brain is amazing and the more I read about it the more fascinated I become with not only it’s limitations, but also it’s immense power. Since I originally wrote the post 30 Amazing Facts About Your Brain I have been on the look out for more amazing tidbits. Here are another 20 for you to wrap your head round, but don’t make the mistake of thinking they don’t apply to you, because they do. 1.

Eidetic memory -photographic memory Overview The ability to recall images in great detail for several minutes is found in early childhood (between 2% and 10% of that age group) and is unconnected with the person's intelligence level. Like other memories, they are often subject to unintended alterations. Persons identified as having a related condition known as Highly Superior Autobiographical Memory (HSAM) are able to remember very intricate details of their own personal life, but this ability seems not to extend to other, non-autobiographical information. Skeptical views The American cognitive scientist Marvin Minsky, in his book The Society of Mind (1988), considered reports of eidetic memory to be an "unfounded myth".

Computer science Computer science deals with the theoretical foundations of information and computation, together with practical techniques for the implementation and application of these foundations History The earliest foundations of what would become computer science predate the invention of the modern digital computer. Blaise Pascal designed and constructed the first working mechanical calculator, Pascal's calculator, in 1642. In 1673 Gottfried Leibniz demonstrated a digital mechanical calculator, called the 'Stepped Reckoner'. He may be considered the first computer scientist and information theorist, for, among other reasons, documenting the binary number system. Although many initially believed it was impossible that computers themselves could actually be a scientific field of study, in the late fifties it gradually became accepted among the greater academic population. It is the now well-known IBM brand that formed part of the computer science revolution during this time. Misc
