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.
- 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.
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.[citation needed] 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.[1][2] The notion of Pareto efficiency can also be applied to the selection of alternatives in engineering and similar fields. Pareto efficiency in short[edit] It is commonly accepted[by whom?] Weak Pareto efficiency[edit] Use in engineering[edit] for each i and

Opportunity cost History[edit] The term was first used in 1914 by Austrian economist Friedrich von Wieser in his book Theorie der gesellschaftlichen Wirtschaft [4] (Theory of Social Economy). The idea had been anticipated by previous writers including Benjamin Franklin and Frédéric Bastiat. Franklin coined the phrase "Time is Money", and spelt out the associated opportunity cost reasoning in his “Advice to a Young Tradesman” (1746): “Remember that Time is Money. He that can earn Ten Shillings a Day by his Labour, and goes abroad, or sits idle one half of that Day, tho’ he spends but Sixpence during his Diversion or Idleness, ought not to reckon That the only Expence; he has really spent or rather thrown away Five Shillings besides.” Bastiat's 1848 essay "What Is Seen and What Is Not Seen" used opportunity cost reasoning in his critique of the broken window fallacy, and of what he saw as spurious arguments for public expenditure.

5 common beliefs about the human brain that are actually totally false MYTH: HUMANS USE ONLY 10 PERCENT OF THEIR BRAIN FACT: The 10 percent myth (sometimes elevated to 20) is mere urban legend, one perpetrated by the plot of the 2011 movieLimitless, which pivoted around a wonder drug that endowed the protagonist with prodigious memory and analytical powers. In the classroom, teachers may entreat students to try harder, but doing so will not light up “unused” neural circuits; academic achievement does not improve by simply turning up a neural volume switch.MYTH: “LEFT BRAIN” and “RIGHT BRAIN” PEOPLE DIFFER FACT: The contention that we have a rational left brain and an intuitive, artistic right side is fable: humans use both hemispheres of the brain for all cognitive functions. The left brain/right brain notion originated from the realization that many (though not all) people process language more in the left hemisphere and spatial abilities and emotional expression more in the right.
Howard Moskowitz Howard Moskowitz is an American market researcher and psychophysicist. He is best known for the detailed study he made of the types of spaghetti sauce and horizontal segmentation. By providing a large number of options for consumers, Moskowitz pioneered the idea of intermarket variability as applied to the food industry.[1] Howard Moskowitz is the CEO of i-Novation Inc as well as President of Moskowitz Jacobs Inc., a firm he founded in 1981. Dr. His latest book with co-author Alex Gofman, Selling Blue Elephants [2] demonstrates and popularizes how IdeaMap (i-Novation`s flagship product) creates new products and messages... from areas as diverse as credit cards, jewelry offers, presidential messaging during election years, stock market communications, and trans-national innovation. Moskowitz has won the Scientific Director`s Gold Medal for outstanding research at the U.S. In 2005, Dr. Products[edit] See also[edit] References[edit] External links[edit]
Neurogenesis: How To Grow New Brain Cells Adults can still grow new brain cells — neurogenesis — but what are they for? For a long time scientists believed that neurogenesis was impossible: adults had all the brain cells they were ever going to have. Now we know that’s not true. In fact, we continue to grow new brain cells into adulthood. The race is on to find out what these brain cells are for and how we can grow more of them. A new review of the scientific literature, published in the journal Trends in Cognitive Sciences, argues that the growth of new cells aids adaptation to the environment (Opendak & Gould, 2015). The authors focus on new cells growing in the hippocampus, an area of the brain linked to memory and learning. Maya Opendak, who co-authored the study, said: “New neurons may serve as a means to fine-tune the hippocampus to the predicted environment.In particular, seeking out rewarding experiences or avoiding stressful experiences may help each individual optimize his or her own brain.” Ms Opendak said:
Psychophysics Psychophysics also refers to a general class of methods that can be applied to study a perceptual system. Modern applications rely heavily on threshold measurement,[3] ideal observer analysis, and signal detection theory.[4] Psychophysics has widespread and important practical applications. History[edit] Many of the classical techniques and theories of psychophysics were formulated in 1860 when Gustav Theodor Fechner in Leipzig published Elemente der Psychophysik.[5] He coined the term "psychophysics", describing research intended to relate physical stimuli to the contents of consciousness such as sensations (Empfindungen). Fechner's work was studied and extended by Charles S. Modern approaches to sensory perception, such as research on vision, hearing, or touch, measure what the perceiver's judgment extracts from the stimulus, often putting aside the question what sensations are being experienced.
