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

Submitted by Tyler Durden.

Submitted by Robert Merry via The National Interest,

In the spring of 2012, The National Interest produced a special issue under the rubric of “The Crisis of the Old Order: The Crumbling Status Quo at Home and Abroad.” The thesis was that the old era of relative global stability, forged through the crucibles of the Great Depression and World War II, was coming unglued. In introducing the broad topic to readers, TNI editors wrote, “Only through a historical perspective can we fully understand the profound developments of our time and glean,...

A Long-Term Look at Inflation

Courtesy of Doug Short.

The April Consumer Price Index for Urban Consumers (CPI-U) released this morning puts the March year-over-year inflation rate at 1.51%, which is well below the 3.88% average since the end of the Second World War and 37% below its 10-year moving average.

For a comparison of headline inflation with core inflation, which is based on the CPI excluding food and energy, see this monthly feature.

French Email Ban Update: "Duty to Disconnect"

Courtesy of Mish.

In response to France Prohibits Sending Work Emails, Answering Cell Phones, Outside Working Hours one reader strenuously objected.

After exchanging numerous emails, his main objection was the accuracy of the title itself "France Prohibits Sending Work Emails, Answering Cell Phones, Outside Working Hours."

Here is the exact headline of the La Vanguardia article that I translated "France prohibits sending mails from work outside working hours".

The reader's big objection? Claiming "France" did this.

What the Market Wants: Positive News and Stocks at Bargain Prices

Courtesy of David Brown, Sabrient Systems and Gradient Analytics

Last week’s market performance was nasty again, especially for the Small-cap Growth style/cap, down 4%.  Large-caps faired the best, losing only 2.7%.  That’s ugly and today’s market seemed likely to be uglier today with escalating tensions over the weekend in Ukraine. 

But once again, positive economic trumped the beating of the war drums. Retail Sales jumped up 1.1% over a projected 0.8% and last month’s tepid 0.3%, which was revised up to 0.7%.  While autos led, sales were up solidly overall.  Business inventories were about as expected with a positive tone.  Citigroup (C) handily beat estimates to add to the morning’s surprises.  As a result, the market was positive through most of the day, led by the DJI, up 0.91%, and the S&P 500, up 0.82%.  NASDAQ had a less...

Winning: Defined as Losing Less

Market Shadows Excelled – With a 1.36% Weekly Decline

In the land of the blind, the one-eyed man is King. Our Virtual Value Porfolio took on that role this week as we lost a modest 1.36% of our value while the DJIA, S&P 500 and Nasdaq Composite dropped from 2.35% - 3.10%.

We remain bullish despite the shaky end of week sentiment. Our original $100,000 now totals $145,058 including our 2.8% cash reserve.

Bearish Prints In DDD Put Options

3D Systems shares had been in positive territory earlier in the session, up as much as 4.2% to touch an intraday high of $50.85. The stock bounced off a low of $47.17 in the early going, a new six-month low for the share price and a more than 50% drop from DDD’s record high of $97.28 reached back on January 3rd. Shares managed to stay in the green for much of the session before succumbing to selling pressure this afternoon. Options expiring next week suggests at least one trader is positioning for further weakness in the near term.

The 17Apr’14 $47 puts traded more than 2,000 times this morning against previously existing open interest o...

To tell you something, I know nothing about.

And so the circus begins in Union Square, San Francisco for this weeks JP Morgan Healthcare Conference.  Will the momentum from 2013, which carried the S&P Spider Biotech ETF to all time highs, carry on in 2014?  The Biotech ETF beat the S&P by better than 3 points.

As I noted in my previous post, Biotechs Galore - IPOs and More, biotechs were rushing to IPOs so that venture capitalists could unwind their holdings (funds are usually 5-7 years), as well as take advantage of the opportune moment...
