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

Expect the Unexpected

 

Expect the Unexpected

I repeat this Jeff Gundlach quote a lot because I love it and it constantly applies to something: “Whenever you hear people in the investment business say ‘Never’, that’s when you know it’s about to happen.”

The Dow is 2.6% away from record highs now that we’re through the fairly lousy earnings season. The SPX is even closer, just 2% away. There’s no reason. Anything can happen.

We’re getting a really great reminder of this every night, courtesy of the NBA East and West finals. Golden State barely lost a game in the regular season and pretty much manhandled their opponents in the first...

France Goes Dark? Staff In 19 French Nuclear Power Plants To Go On Strike Tomorrow

Submitted by Tyler Durden.

Following strikes over the unpopular French labor reform, that started over the weekend and crippled the French refining industry leading to gasoline shortages and rationing, things are about to get far more serious for the country whose economy has already been threatened with a sharp slowdown as a result of a relentless wave of labor unrest. According to Reuters, staff in France's 19 nuclear plants - which by definition we assume is essential -...

49 Years of Income and Home Values

Courtesy of Doug Short's Advisor Perspectives.

Often conversations about home buying end up in discussions on the high cost of homes today and their affordability – or lack thereof.

We decided to take a look at the long-term trends in home prices in comparison to income and found that incomes have been stagnant since the early 1970s, while home prices have risen dramatically in comparison.

In order to analyze income, we have used the Middle Quintile for households, which is the middle 20% of all households adjusted for inflation, with 2014 as our base year. The Census Bureau, our source for income data, began publishing annual reports for gross household incomes in 1967. For median home prices, our source is the American Household Survey, wh...

The Biggest Bitcoin Arbitrage Ever?

Courtesy of Chris at CapitalistExploits

Do you remember when you were growing up and all your friends were allowed Atari game consoles but you weren’t?

Well, I do and the things seemed as foreign to me as Venus. Mostly because the little time I managed to spend on the gaming consoles when my friends weren’t hogging them I found it all a bit silly. I never “got” computer games, and to this day still have poor comprehension of things like Angry Birds.

I suspect that many people around the world view Bitcoin in the same way as I view Angry Birds: with mild amusement and a general lack of understanding as to what the hell all the fuss is about.

I was thinking of this since a buddy of mine recently started ...

This Is Why Biotech Stocks May Explode Again

Reminder: Pharmboy and Ilene are available to chat with Members.

Here's an interesting article from Investor's Business Daily arguing that biotech stocks are beginning to recover from their recent declines, notwithstanding current weakness.

This Is Why Biotech Stocks May Explode Again

Excerpt:

After a three-year bull run that more than quadrupled its value by its peak last July, IBD’s Medical-Biomed/Biotech Industry Group plunged 50% by early February, hurt by backlashes against high drug prices and mergers that seek to lower corporate taxes.

About that debate last night

Although we try to stay focused on finding and managing promising trade ideas, the comments in the comment section sometimes take a political turn (for access, try PSW — click here!). So today, Jean Luc writes,

The GOP debate last night was just unreal – are these people running to be president of the US or to lead a college fraternity! Comparing tool size? The only guy that looks semi-sane is Kasich. The other guys are just like 3 jackals right now. 

And something else – if Trump is the candidate, that little Romney speech yesterday is probably already being made into a commercial. And all these little snippets from the debate will also make some nice ads! If you are a conservative, you have to be scared now.

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.
