Driven toward reward without regard for consequence

This is interesting. However, the conclusion that "individuals with antisocial personality disorder may not be unaware of… consequences… but instead that their intense reward-seeking motivation consumes their attention wholly until they have fulfilled their desire for reward" seems overstated, and only a small piece of the psychopath puzzle.

For a different perspective, that of a financial writer, and an even farther-fetched conclusion, read the second article below. The same data can be interpreted to show that a trader taking on excessive risk is "hopped up on dopamine" so they can’t see negative consequences, making them "kind of a psychopath." Take all this with a grain of salt haloperidol. - Ilene 

Driven toward reward without regard for consequence

Courtesy of TIME, by Tiffany O’Callaghan

TIMEAn overactive dopamine reward system in the brain may help explain why psychopaths pursue rewards without regard for consequences, according to new research published this week in the journal Nature Neuroscience. Previous research has found that individuals who suffer from antisocial personality disorder—often referred to as sociopathology or psychopathology, despite debate over whether these are distinct conditions—lack empathy and fear. Yet this new study, from researchers at Vanderbilt University examines what these individuals may have in excess. According to the study, led by Joshua Buckholtz, a graduate student in psychology at Vanderbilt, individuals with antisocial personality disorder traits show signs of dysfunction in dopamine reward systems—suggesting that, in psychopaths, the drive toward reward can overwhelm all else.

Prior to participating in two different experiments, study subjects completed personality tests to identify presence and severity of psychopathic characteristic—including aggression, lack of empathy, and capacity for manipulation, among other things. Drawing on previous research that has established a strong link between substance abuse and psychopathology, in the first experiment researchers gave participants amphetamine, then used functional Magentic Resonance Imaging (fMRI) brain scans to monitor how dopamine release was affected by the stimulant. In a second experiment, study participants were told that they would be paid for performing a simple task, and researchers conducted brain scans while they completed the tasks.

In both experiments, researchers found that participants who had psychopathic characteristics according to the personality test, were more likely than those without those traits to have greater activity in the nucleus accumbens, the area of the brain associated with dopamine reward processing—whether in response to the chemical stimulant, or the suggestion of monetary reward.

The findings suggest that individuals

Nigel Farage: "Trump Is The New Reagan"

Courtesy of ZeroHedge. View original post here.

A few days after wowing thousands of Republicans at a rally in Jackson, Mississippi, "Mr. Brexit" Nigel Farage, penned a letter (presented below) to the Daily Mail describing Trump as the "new Ronald Reagan."  Even though he stopped short of endorsing Trump, a decision he made after condemning Obama for interjecting himself into the Brexit discussion, he did note that he "would not vote for Hillary Clinton even if she paid me."

"I did not endorse Trump, because I ha...

Boyar Value Group 2Q Letter - Some Thoughts About The Market

By VW Staff. Originally published at ValueWalk.

Boyar Value Group letter for the second quarter ended June 30, 2016.

Boyar Value Group – Some Thoughts About The Market

The two-day decline in the U.S. stock market subsequent to Great Britain’s decision to exit the European Union saw the Dow Jones Industrial Average plummet by 871 points. However, it climbed 809 points in the next four days and continued its ascent thereafter.

This leaves investors in a familiar quandary: Questioning what catalysts could spur the market to new highs. In our last quarterly letter, we mentioned the Federal Reserve had forecasted four interest rate hikes for 2016. We opined that in all likelihood there would be only one additional rate hike, and that might not come until after the presidential election. The fragile global economic outlook coupled with anemic dome...

The Fed: Myths vs. Reality

 

The Fed: Myths vs. Reality

Courtesy of Wade of Investing Caffeine

Traders, bloggers, media talking heads, and pundits of all stripes went into a feverish sweat as they anticipated the comments of Federal Reserve Chairman Janet Yellen at the annual economic summit held in Jackson Hole, Wyoming. When Yellen, arguably the most dovish Fed Chairman in history, uttered, “I believe the case for an increase in the federal funds rate has strengthened in recent months,” an endless stream of commentators used this opportunity to spout out a never-ending stream of predictions describing the looming consequences of such a potential rate increase.

As I’ve stated before, the Fed receives both too much blame and too much credit for...

World Markets Weekend Update: Six of the Eight Post Losses ... Again

Courtesy of Doug Short's Advisor Perspectives.

Only two of the eight equity indexes on our global watch list posted week-over-week gains in our latest update, same as last week. The two Eurozone indexes, France's CAC and Germany's DAXK, were the two who finished in the green, a shift from the Asian advance the previous week, when the Shanghai and Hang Seng were the sole gainers. In fact, the Shanghai Composite did a complete flip from its 1.88% gain the previous week to its -1.22% finish on Friday. The average of the eight improved fractionally from -0.56% the previous week to -0.39% for the latest.

Epizyme - A Waiting Game

Reminder: Pharmboy is available to chat with Members, comments are found below each post.

Epizyme was founded in 2007, and trying to create drugs to treat patient's cancer by focusing on genetically-linked differences between normal and cancer cells. Cancer areas of focus include leukemia, Non-Hodgkin's lymphoma and breast cancer.  One of the Epizme cofounders, H. Robert Horvitz, won the Nobel Prize in Medicine in 2002 for "discoveries concerning genetic regulation of organ development and programmed cell death."

Before discussing the drug targets of Epizyme, understanding epigenetics is crucial to comprehend the company's goals.  

Genetic components are the DNA sequences that are 'inherited.'  Some of these genes are stronger than others in their expression (e.g., eye color).  Yet, some genes turn on or off due to external factors (environmental), and it is und...

Help One Of Our Own PSW Members

"Hello PSW Members –

This is a non-trading topic, but I wanted to post it during trading hours so as many eyes can see it as possible.  Feel free to contact me directly at jennifersurovy@yahoo.com with any questions.

Last fall there was some discussion on the PSW board regarding setting up a YouCaring donation page for a PSW member, Shadowfax. Since then, we have been looking into ways to help get him additional medical services and to pay down his medical debts.  After following those leads, we are ready to move ahead with the YouCaring site. (Link is posted below.)  Any help you can give will be greatly appreciated; not only to help aid in his medical bill debt, but to also show what a great community this group is.
