Psychopathic Traits Linked to Brain Reward System - NIH Research Matters

Psychopathic Traits Linked to Brain Reward System - NIH Research Matters
March 29, 2010 People who scored high on a test that measures impulsive and antisocial traits had exaggerated brain responses to certain “rewards,” like winning money or taking stimulant drugs. The new study provides evidence that a dysfunctional brain reward system may underlie vulnerability to a personality disorder known as psychopathy. Impulsive and antisocial personality traits correlate with amphetamine-induced dopamine release (red and yellow) in the brain. Psychopathy is characterized by a combination of superficial charm, manipulative and antisocial behavior, impulsivity, blunted empathy and shallow emotional experiences. Many studies of psychopathy have focused on the emotional and interpersonal aspects of the disorder, like lack of fear and empathy. In one experiment, the researchers used positron emission tomography (PET) to image the brain’s dopamine response when participants received a low oral dose of amphetamine.

The Psychopath: The Mask of Sanity THE PSYCHOPATH - The Mask of Sanity Special Research Project of the Quantum Future School Imagine - if you can - not having a conscience, none at all, no feelings of guilt or remorse no matter what you do, no limiting sense of concern for the well-being of strangers, friends, or even family members. And pretend that the concept of responsibility is unknown to you, except as a burden others seem to accept without question, like gullible fools. Now add to this strange fantasy the ability to conceal from other people that your psychological makeup is radically different from theirs. You are not held back from any of your desires by guilt or shame, and you are never confronted by others for your cold-bloodedness. In other words, you are completely free of internal restraints, and your unhampered liberty to do just as you please, with no pangs of conscience, is conveniently invisible to the world. How will you live your life? Provided you are not forcibly stopped, you can do anything at all.

Ten Politically Incorrect Truths About Human Nature Human nature is one of those things that everybody talks about but no one can define precisely. Every time we fall in love, fight with our spouse, get upset about the influx of immigrants into our country, or go to church, we are, in part, behaving as a human animal with our own unique evolved nature—human nature. This means two things. First, our thoughts, feelings, and behavior are produced not only by our individual experiences and environment in our own lifetime but also by what happened to our ancestors millions of years ago. Second, our thoughts, feelings, and behavior are shared, to a large extent, by all men or women, despite seemingly large cultural differences. Human behavior is a product both of our innate human nature and of our individual experience and environment. The implications of some of the ideas in this article may seem immoral, contrary to our ideals, or offensive. Why Beautiful People Have More Daughters,

The way out is to give up the idea of certain knowledge. Axioms by Robert G. Dedication This book is dedicated to the giants of mathematical and scientific philosophy upon whose backs it stands: Plato, Hume, Descartes, Gödel, Bayes, Shannon, Cantor, Cox, Jaynes, and many more, too many to count, actually. It is also dedicated to my philosophy professor and guru at Duke, George Roberts, who had an enormous impact on me as I pursued an ``invisible'' philosophy major at Duke to accompany my physics major (invisible because at the time Duke had no way of acknowledging the completion of a Bachelor of Science in one discipline and a Bachelor of Arts in another).

- StumbleUpon And enhancing cognitive prowess later in life could naturally influence one's openness to new experiences, according to a new set of studies. VLADGRIN/Shutterstock Every day it seems like researchers are discovering something else that overturns long-held notions about how the brain operates. Seniors from 60 to 94 years old were split into two groups: One group was assigned to a 16-week course of brain puzzles, completed at home; the other received no special treatment. The brain games challenged the participants' inductive reasoning skills: for example, finding patterns in numbers and letters, along with crossword puzzles and Sudoku puzzles. All participants took tests that measured their inductive reasoning skills both before and after the 16-week study period. The participants also took tests that measured the "big five" personality traits: openness, extraversion, agreeableness, conscientiousness, and neuroticism.

Easter Island drug raises cognition throughout life span in mice Cognitive skills such as learning and memory diminish with age in everyone, and the drop-off is steepest in Alzheimer's disease. Texas scientists seeking a way to prevent this decline reported exciting results this week with a drug that has Polynesian roots. The researchers, appointed in the School of Medicine at The University of Texas Health Science Center San Antonio, added rapamycin to the diet of healthy mice throughout the rodents' life span. "We made the young ones learn, and remember what they learned, better than what is normal," said Veronica Galvan, Ph.D., assistant professor of physiology at the Barshop Institute for Longevity and Aging Studies, part of the UT Health Science Center. The drug also lowered anxiety and depressive-like behavior in the mice, Dr. Venturing into the open Mice are burrowers that prefer tunnels with walls. Mice with less anxiety were more curious to explore the catwalk. The second test measured depressive-like behavior in the rodents. Dr.

Hare Psychopathy Checklist - define, person, people, used, personality, score, traits, Definition, Purpose Definition The Hare Psychopathy Checklist-Revised (PCL-R) is a diagnostic tool used to rate a person's psychopathic or antisocial tendencies. People who are psychopathic prey ruthlessly on others using charm, deceit, violence or other methods that allow them to get with they want. The symptoms of psychopathy include: lack of a conscience or sense of guilt, lack of empathy, egocentricity, pathological lying, repeated violations of social norms, disregard for the law, shallow emotions, and a history of victimizing others. Originally designed to assess people accused or convicted of crimes, the PCL-R consists of a 20-item symptom rating scale that allows qualified examiners to compare a subject's degree of psychopathy with that of a prototypical psychopath. It is accepted by many in the field as the best method for determining the presence and extent of psychopathy in a person. Purpose The PCL-R is used for diagnosing psychopathy in individuals for clinical, legal or research purposes.

mental_floss Blog » 7 Curious Facts About 7 Dr. Seuss Books 1. Hop on Pop In an early draft of the book, Theodor S. Geisel (aka Dr. Seuss) wanted to make sure his publisher, Bennett Cerf, was reading the manuscripts he was turning in, so instead of this line: “My father / can read / big words, too. / Like... / Constantinople / and / Timbuktu” the manuscript read as follows: “When I read I am smart / I always cut whole words apart. / Con Stan Tin O Ple, Tim Buk Too / Con Tra Cep Tive, Kan Ga Roo." 2. Again, we have a story here involving Cerf. 3. This neat tidbit involves another challenge, though not from Cerf, from a Life Magazine article about illiteracy rates. Seuss read the piece and immediately began working on The Cat In The Hat, which took him nine months to write! 4. This book has been the subject of much brouhaha. 5. Published in 1937, this was Seuss’ first children's book. 6. Published in 1958, Yertle is full of metaphors and allusions that deal with fascism. 7.

Euthyphro dilemma The dilemma has had a major effect on the philosophical theism of the monotheistic religions, but in a modified form: "Is what is morally good commanded by God because it is morally good, or is it morally good because it is commanded by God?" Ever since Plato's original discussion, this question has presented a problem for some theists, though others have thought it a false dilemma, and it continues to be an object of theological and philosophical discussion today. The dilemma[edit] Socrates and Euthyphro discuss the nature of piety in Plato's Euthyphro. At this point the dilemma surfaces. In philosophical theism[edit] The dilemma can be modified to apply to philosophical theism, where it is still the object of theological and philosophical discussion, largely within the Christian, Jewish, and Islamic traditions. Explanation of the dilemma[edit] The first horn[edit] Problems[edit] The second horn[edit] Problems[edit] This horn of the dilemma also faces several problems: Jewish thought[edit]

The Reality of Repressed Memories In 1990, a landmark case went to trial in Redwood City, California. The defendant, George Franklin, Sr., 51 years old, stood trial for a murder that had occurred more than 20 years earlier. The victim, 8-year-old (Susan Kay Nason, was murdered on September 22, 1969). Franklin's daughter, Eileen, only 8 years old herself at the time of the murder, provided the major evidence against her father. Eileen's memory did not come back all at once. Eileen's memory report was believed by her therapist, by several members of her family, and by the San Mateo County district attorney's office, which chose to prosecute her father. Eileen's detailed and confident memory impressed a number of people. On the other hand, the clinical anecdotes and the loose theory used to explain them remain unconvincing to some psychotherapists and to many laboratory researchers. More Repressed Memories Soon after the Franklin case, a string of others involving newly emerged distant memories appeared in the media.

Psychology | Education | Education Guardian What will I learn?Psychology is the study of the human mind to better understand how andwhy people act the way they do. So, you might find yourself investigating how people become anorexic, how seemingly calm people turn violent, or why people prefer chocolate to sex (at least sometimes). You'll look at the way the brain perceives and uses information, and how these processes change as you get older. Your first year should provide a general grounding in general psychology, which will introduce you to the wonderful world of psychological statistics (maths GCSE is a must, but you don't need A-level, so you can relax). From there you will look at child development, cognitive psychology, personality, memory, emotion and motivation, and modules that look at the social psychology of individuals and groups. Some applied psychology programmes will give you the chance to spend a year working with a chartered psychologist, perhaps in healthcare or education. What skills will I gain?

CNN.com - 'Corporate psychopaths' at large - Aug 26, 2004 Why Are 80% of Harvard Students First-Borns? That’s my estimate anyways. I remember it like it was yesterday. It was my freshman year at Harvard, and I was going to the first lecture of “Justice” – one of the most popular classes on campus. Because birth order matters according to Dr. First Child: perfectionist, reliable, conscientious, a list maker, well organized, hard driving, a natural leader, critical, serious, scholarly, logical, doesn’t like surprises, a techie. Middle Child: mediator, compromising, diplomatic, avoids conflict, independent, loyal to peers, has many friends, a maverick, secretive, used to not having attention. Youngest Child: manipulative, charming, blames others, attention seeker, tenacious, people person, natural salesperson, precocious, engaging, affectionate, loves surprises.

Mental State Called Flow A number of sources, most recently ProgrammingOutsideTheCube and the RingerTape page, say that many folk find it takes time to get into a state where work flows. Do you plan to get into flow, does it come upon you more as a kind of inspiration, or is it not necessary for you? Do you use tactics to improve your team's ability to flow? Which particular events disrupt flow the most, and how do you solve them? For me, flow requires both inspiration and expiration, if that makes sense. Interesting but difficult to summarize: The mental state that psychologists call "flow", and its impact on your project, are well described in chapter 10 ("brain time versus body time") of PeopleWare. About 20-30 minutes of Zen meditation once or twice per day should be a great help. I find problems draw me into them. Flow to me is evidenced in looking up ten minutes later to find that hours have elapsed. MicroSoft has a tack on this sort of thing.
