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

Deutsche Bank: "If The Fed Stick To Their Script Then The Market Could Be In For A Small Shock"

Courtesy of ZeroHedge. View original post here.

Submitted by Tyler Durden.

The only preview you need of today's first FOMC statement for 2015, one which has already cornered Yellen as any additional USD strength from here on out will certainly be economy and S&P500 negative, and who as Deutsche summarizes is damned if she does, and damned if she doesn't, and that as Jim Reid politely puts it, "something will have to give at some point."

From DB's Jim Reid:

One wonders how careful the Fed will be in 2015. We may get some early clues today after the conclusion of the first FOMC meeting of the year. This meeting isn’t going to see the release of the Fed’s Summary of Economic Projections, nor a press conference but nevert...

Clash Over Sanctions: Syriza Opposes Sanctions on Russia, Calls Them "Neocolonial Bulimia"; Negotiation Rules

Courtesy of Mish.

The Blowout Victory of Syriza has taken on some new meaning outside of Grexit possibilities.

Please consider Greeks Rebuff EU Call for More Russia Sanctions.
A spokesman for the ruling coalition of Alexis Tsipras, prime minister, said Greece had not approved a statement from EU heads of government that asked their foreign ministers to review further sanctions in response to the latest flare-up of violence in eastern Ukraine, blamed by the US and most European nations on Russian-backed separatists.

The Greek statement raised questions over whether the new government, led by the radical leftist Syriza party, would s...

Sector Detector: With the Fed fading into shadows, investors look overseas for new catalysts

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

By Scott Martindale

Last week, the S&P 500 put an end to its streak of weekly losses, despite giving back some gains on Friday. Thursday provided the big catalyst, with the ECB’s announcement of its bold new monetary stimulus plan. Investors were cheered and soothed for the moment. And U.S. fundamentals still look strong. But with Greece trying to turn back time, with volatility elevated (and likely to continue as such), and with the technical situation still dicey, the near term outlook is still worrisome.

In this weekly update, I give my view of the current market environment, offer a technical analysis of the S&P 500 chart...

Jitters After Bitcoin Exchange Suspends Services

So as I was saying yesterday (Bitcoin: The Biggest Clown Show In History?), Bitcoin has several obstacles on the path to potential success as an alternative currency. But I forgot to mention hacking and theft at Bitcoin exchanges and other technical problems. This is related to the lack of government backing and the fact that the value of Bitcoins is based entirely on confidence.

2015 - Biotech Fever

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

PSW Members - well, what a year for biotechs!   The Biotech Index (IBB) is up a whopping 40%, beating the S&P hands down!  The healthcare sector has had a number of high flying IPOs, and beat the Tech Sector in total nubmer of IPOs in the past 12 months.  What could go wrong?

Phil has given his Secret Santa Inflation Hedges for 2015, and since I have been trying to keep my head above water between work, PSW, and baseball with my boys...it is time that something is put together for PSW on biotechs in 2015.

Cancer and fibrosis remain two of the hottest areas for VC backed biotechs to invest their monies.  A number of companies have gone IPO which have drugs/technologies that fight cancer, includin...

SPX Call Spread Eyes Fresh Record Highs By Year End

Stocks got off to a rocky start on the first trading day in December, with the S&P 500 Index slipping just below 2050 on Monday. Based on one large bullish SPX options trade executed on Wednesday, however, such price action is not likely to break the trend of strong gains observed in the benchmark index since mid-October. It looks like one options market participant purchased 25,000 of the 31Dec’14 2105/2115 call spreads at a net premium of $2.70 each. The trade cost $6.75mm to put on, and represents the maximum potential loss on the position should the 2105 calls expire worthless at the end of December. The call spread could reap profits of as much as $7.30 per spread, or $18.25mm, in the event that the SPX ends the year above 2115. The index would need to rally 2.0% over the current level...

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.
