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

The Future of Medicine? Forget Private Doctor Appointments, Group Medical Visits are Coming

Submitted by Tyler Durden.

Submitted by Mike Krieger via Liberty Blitzkrieg blog,

According to the American Academy of Family Physicians, around 10 percent of family doctors already offer shared medical appointments, sessions that bring together a dozen or more patients with similar medical conditions to meet with a doctor for 90 minutes. With pressure from the government and insurers to bring down the cost of care while treating the increasing number of people with health insurance, patients can expect group ...

Moving Averages: Month-End Preview

Courtesy of Doug Short.

Here is an advance preview of the monthly moving averages I track after the close of the last business day of the month. At this point, before the open on the last day of the month, three S&P 500 strategies are now signaling "invested" -- unchanged from last month. Two of the five of the Ivy Portfolio ETFs, Vanguard FTSE All-World ex-US ETF (VEU) and PowerShares DB Commodity Index Tracking (DBC), are signal "cash" -- also unchanged from last month.

If a position is less than 2% from a signal, it is highlighted in yellow.


Note: My inclusion of the S&P 500 index updates is intended to illustrate a popular moving moving-average timing strategy. The index signals also give...

Greece Will Not Accept Bailout Extension or Deal With "Rottenly Constructed" Troika; Mish's Game Theory Math

Greece Will No Longer Deal with ‘Troika’

It now strongly appears as if Greece, Germany, and the nannycrats in Brussels are all on one hell of a collision course. Both sides have dug in, and the war of words has escalated in all corners.

For example, please consider Greece Will No Longer Deal with ‘Troika’, Yanis Varoufakis Says
Greece will no longer co-operate with the “troika” of international lenders that has overseen its four-year bailout programme, the country’s finance minister said.

Yanis Varoufakis also said Greece would not accept an extension of its EU bailout, which expires at the end of February, and without which Greek banks could be shut off from European Centr...

What Would You Do?

What Would You Do?

Courtesy of Paul Price

Suppose you had the technical ability and raw materials to print up counterfeit dollars, euros or yen that were identical to the real things. Assume you could spend them as fast as you could create them with no fear of any repercussions.

Would you prudently print up only as much fresh currency as you needed for your current lifestyle? Would you create just a bit more than that to help relatives or those in need?

It is most likely you’d have your printing press running 24 hours a day, seven days a week. Becoming the richest person in the world would confer great power upon you.

You could rationalize this action because you plan to use the money for good purposes. Imagine the warm feeling you’d get by giving every person in America one million do...

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.

Thank you for you time!
