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

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

Fun, Fun, Fun ... 'til her daddy takes the T-bird away

Well no one is having fun anymore. Here's Paul Price's take on the latest Greek drama.

Fun, Fun, Fun … ‘til her daddy takes the T-bird away

By Paul Price

The popular press has made Germany into the villain of the current Greek drama (and popular bloggers point out the role of Goldman Sachs.) Why, they ask, should Berlin be dictating how the Greek government runs its own country? 

Understanding the reasoning for that is quite simple if you think in terms of the Beach Boys’ old hit song, Fun, Fun, Fun.

Greece is the wayward “daughter.&...

For Greeks The Nightmare Is Just Beginning: Here Come The Depositor Haircuts

Submitted by Tyler Durden.

With capital controls already imposed on Greece, some have wondered if this is as bad as it gets. Unfortunately, as the Cyprus "template" has already shown us, for Greece the nightmare on Eurozone street is just beginning.

As a reminder, over the past few months there have been recurring rumors that as part of its strong-arming tactics the ECB may eventually move to raise the haircuts the Bank of Greece is required to apply to assets pledged by Greek banks as ...

Sector Detector: Bulls under the gun to muster troops, while bears lie in wait

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

Two weeks ago, bulls seemed ready to push stocks higher as long-standing support reliably kicked in. But with just one full week to go before the Independence Day holiday week arrives, we will see if bulls can muster some reinforcements and make another run at the May highs. Small caps and NASDAQ are already there, but it is questionable whether those segments can drag along the broader market. To be sure, there is plenty of potential fuel floating around in the form of a friendly Fed and abundant global liquidity seeking the safety and strength of US stocks and bonds. While the technical picture has glimmers of strength, summer bears lie in wait.

Shares of Baxalta will be given as a tax-free dividend, in the ratio of one to one, to BAX holders on record on June 17, 2015.

An update on oil proxies

Courtesy of Jean-Luc Saillard

Back in December, I wrote a post on my blog where I compared the performances of various ETFs related to the oil industry. I was looking for the best possible proxy to match the moves of oil prices if you didn't want to play with futures. At the time, I concluded that for medium term trades, USO and the leveraged ETFs UCO and SCO were the most promising. Longer term, broader ETFs like OIH and XLE might make better investment if oil prices do recover to more profitable prices since ETF linked to futures like USO, UCO and SCO do suffer from decay. It also seemed that DIG and DUG could be promising if OIH could recover as it should with the price of oil, but that they don't make a good proxy for the price of oil itself.

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.
