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

Peso Soars To Pre-Brexit Levels As Mexico Raises Rates More Than Expedcted

Courtesy of ZeroHedge. View original post here.

A day after the most awkward three-way handshake in history between Obama, Trudeau, and Nieto, the latter's central bank just pushed rates higher by a bigger than expected 50bps to 4.25% (exp +25bps). The Peso is surging back (extending its bounce off January lows) retracing all the post-Brexit losses... on what seems like fears of a surge in food inflation.

Mapping The Market

Thoughts on Brexit

I have mixed feelings about Brexit today. Clearly the European institution need reforming. The addition of so many countries in the last 20 years has created a top heavy administration. The Euro adds more complexities to the equation as the ECB policies cannot fit every country's problem. On the other hand, a unified Europe has advantages as well – some countries have benefited from the integration.

For Britain, it's hard to say what the final price will be. My guess is that Scotland might now vote for independence as they supported staying in Europe overwhelmingly. Northern Ireland might be tempted to leave as well so possibly RIP UK in the long run. I was talking to some French people and they were saying that now there might be no incentive for France to stop immigrants from crossing over to the UK like they do now and simply allow for travel there and let the UK deal with them. The end game is not clear to anyone at the moment....

One week ago, when bitcoin first crossed above $700 on the seemingly insatiable Chinese buying which we forecast last September (when bitcoin was trading at $230) would take place as a result of China's capital controls (to much pushback by the "mainstream" financial media), we tried to predict what may happen next. We said that "it could go much higher. That said, anyone who bought last September when the digital currency was trading at $230 may be advised to take some profits, and at least make...

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.
