An Evaluation of the Left-Brain vs. Right-Brain Hypothesis with Resting State Functional Connectivity Magnetic Resonance Imaging Lateralized brain regions subserve functions such as language and visuospatial processing. It has been conjectured that individuals may be left-brain dominant or right-brain dominant based on personality and cognitive style, but neuroimaging data has not provided clear evidence whether such phenotypic differences in the strength of left-dominant or right-dominant networks exist. We evaluated whether strongly lateralized connections covaried within the same individuals. Data were analyzed from publicly available resting state scans for 1011 individuals between the ages of 7 and 29. For each subject, functional lateralization was measured for each pair of 7266 regions covering the gray matter at 5-mm resolution as a difference in correlation before and after inverting images across the midsagittal plane. The difference in gray matter density between homotopic coordinates was used as a regressor to reduce the effect of structural asymmetries on functional lateralization. Figures Table 1.
Pour un Redressement productif… et créatif La mission de «redressement productif» donnée au ministère de l’Industrie, induisant sa nouvelle dénomination, suppose des changements assez profonds dans notre politique d’innovation, et pas seulement des évolutions de dosage de ses ingrédients classiques. Il y a en France deux approches dominantes de l’innovation : d’un côté, celle qui, radicale, met la recherche techno-scientifique à sa source, dans une démarche plutôt linéaire et déductive, vision prépondérante dans les administrations et dans de grands groupes industriels ; d’un autre, une approche incrémentale, pratique quotidienne des entreprises de toutes tailles et spécialités. Face aux nombreux défis à relever, sociétaux et environnementaux, sociaux et économiques - le redressement productif -, la troisième voie est celle de l’innovation conceptuelle, l’innovation caractérisée par des façons originales de penser, de faire, d’organiser. Comment pousser l’innovation conceptuelle ?
Left Brain vs. Right: It's a Myth, Research Finds It's the foundation of myriad personality assessment tests, self-motivation books and team-building exercises – and it's all bunk. Popular culture would have you believe that logical, methodical and analytical people are left-brain dominant, while the creative and artistic types are right-brain dominant. Trouble is, science never really supported this notion. Now, scientists at the University of Utah have debunked the myth with an analysis of more than 1,000 brains. They found no evidence that people preferentially use their left or right brain. A paper describing this study appeared in August in the journal PLOS ONE. [10 Things You Didn't Know About the Brain] The preference to use one brain region more than others for certain functions, which scientists call lateralization, is indeed real, said lead author Dr. "It is not the case that the left hemisphere is associated with logic or reasoning more than the right," Anderson told LiveScience.
Obsessive Debunking Disorder (ODD)? By Thomas Sheridan | Thomas Sheridan Arts Are Hardcore Skeptics and Debunkers Actually Brain Deficient? Their Own Beloved Hard Science Might Well Suggest Many Are. We have all encountered them. The reality is that apart from their own kindother self-proclaimed non-idiotsmost people find such arrogant and obnoxious debunkers and hardcore skeptics to be strangely angry and boorish, and often confrontational to the point of hysterical. However, when you strip down their whole mandate into its constituent parts, one soon finds that most of these scientifically minded crusaders have no actual accredited scientific background, and the entire thrust of their endeavours remains nothing less than unconditional servitude and unquestioned devotion to authority figures and the status quo. It is only fair to point out that there are also healthy skeptics who genuinely do look at anomalies and unexplained phenomena within the natural and unseen cosmos with a cautious eye. So what gives?
New Study Questions Myth Of Left-Brained And Right-Brained Personality Traits According to new research from University of Utah neuroscientists, no evidence exists within brain imaging that pinpoints a difference in the way humans use their brains. The left-brained and right-brained discussion has greatly shaped popular culture's view on personality types, leading to the widely accepted idea that some people employ one side of the brain more than others. For two years, researchers studied lateralization of brain function -- the mental processes that are specific to one side of the brain. The brain scans used in the study were taken from a database called INDI, the International Neuroimaging Data-Sharing Initiative. The scientists broke up the brain into 7,000 regions, examining which areas were more lateralized. The orange shaded areas show parts of the brain in the left and right hemisphere that are responsible for moving this patient's hand. “It’s absolutely true that some brain functions occur in one or the other side of the brain.
Blog | Facilitation Graphique Si il y a une chose que j’ai apprise lors de la conférence Euviz 2014 de Berlin (voir le post précédent), c’est la différence entre Graphic Recording et Graphic Facilitation. Cette distinction et ce questionnement sont revenus plusieurs fois sur mon parcours des 4 jours de pré-conférence et de conférence. Ils ont été discutés avec des personnes d’âge, de pays, d’expériences, de parcours différents. Des éléments de réponses ont été apporté sur différents point de vu : la posture/rôle, le périmètre d’action, les synergies, les objectifs, les spécificité et points communs. Prenons d’abord un peu de recul. En France, ces pratiques de visualisation sont formellement apparues il y a environ 15 ans avec un noyau de praticiens émergeant au sein du réseau ASE de Capgemini et utilisant une terminologie spécifique à la méthode MG Taylor. Les origines des praticiens se diversifiant, beaucoup de vocabulaires différents sont employés. Doit-on tous s’aligner sur le vocabulaire ?
You Can't See It, But You'll Be A Different Person In 10 Years : Shots - Health News iStockphoto.com No matter how old people are, they seem to believe that who they are today is essentially who they'll be tomorrow. That's according to fresh research that suggests that people generally fail to appreciate how much their personality and values will change in the years ahead — even though they recognize that they have changed in the past. Daniel Gilbert, a psychology researcher at Harvard University who did this study with two colleagues, says that he's no exception to this rule. "I have this deep sense that although I will physically age — I'll have even less hair than I do and probably a few more pounds — that by and large the core of me, my identity, my values, my personality, my deepest preferences, are not going to change from here on out," says Gilbert, who is 55. He realized that this feeling was kind of odd, given that he knows he's changed in the past. Gilbert says that he and his colleagues wanted to investigate this idea, but first they had to figure out how.
Kübler-Ross model The model was first introduced by Swiss-American Psychiatrist Elisabeth Kübler-Ross in her 1969 book, On Death and Dying, and was inspired by her work with terminally ill patients. Motivated by the lack of curriculum in medical schools on the subject of death and dying, Kübler-Ross began a project which examined death and those faced with it while working as an instructor at the University of Chicago's medical school. Kübler-Ross' project evolved into a series of seminars which, along with patient interviews and previous research became the foundation for her book, and revolutionized how the U.S. medical field takes care of the terminally ill. In the decades since the publication of "On Death and Dying", the Kübler-Ross concept has become largely accepted by the general public; however, its validity has yet to be consistently supported by the majority of research studies that have examined it. Stages The stages, popularly known by the acronym DABDA, include:
Handedness and Brain Lateralization The human brain is a paired organ; it is composed of two halves (called cerebral hemispheres) that look pretty much alike. The term brain lateralization refers to the fact that the two halves of the human brain are not exactly alike. Each hemisphere has functional specializations: some function whose neural mechanisms are localized primarily in one half of the brain. In humans, the most obvious functional specialization is speech and language abilities. Most humans (but not all) have left hemisphere specialization for language abilities. «Handedness» is a vague term, and can mean many things to many people. The same chap that identified a region of the brain specialized for language Paul Broca (Paul Broca) also suggested that a person's handedness was opposite from the specialized hemisphere (so a right-handed person probably has a left-hemispheric language specialization).
Far-Fetched Ideas Are Fun. But Innovation Usually Starts Small A few weeks ago, The New York Times Magazine gave us “32 Innovations That Will Change Your Tomorrow.” I’ll admit that as I read about many of the ideas, I couldn’t help but think, “Wow. This is cool.” But innovation is about more than cool. Take, for example, Idea #23: The tooth sensor. In theory, it’s a great innovation--it could improve people’s health through prevention and early detection while lowering both personal and national health care costs. So beyond the Cool Factor, what else should we keep in mind when we develop innovative ideas? 1. When we’re faced with a major problem, we often expect that we need a huge solution to solve it. 2. It’s the late ’90s, and the diaper wars are on. Continuum partnered with Pampers and helped them redesign their diapers in ways that not only addressed key functional concerns--such as absorbency--but also aligned with what mattered most to moms: supporting the developmental growth of their babies. 3.

Do all personality disorders have a common psychodynamic source? To what stage of personal development can we attribute this common source? Can the paths leading from that common source to each of these disorders be charted? Will positive answers to the above endow us with a new understanding of these pernicious conditions? Acute Anger Anger is a compounded phenomenon. Most personality disordered people are prone to be angry. Pathological anger is neither coherent, not externally induced.
