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

10Y ACGB Not Modeled By Australian Economic Fundamentals: DB

By Mani. Originally published at ValueWalk.

For modelling 10Y ACGB yield, usage of market rates such as the 10Y UST yield and relative front-end pricing would be preferred rather than a model based on Australian domestic economic fundamentals, believe analysts at Deutsche Bank AG (NYSE:DB) (ETR:DBK) (FRA:DB). David Plank suggests in his July 29 report titled “Australia: Modeling the 10Y ACGB” that the China/U.S. growth gap would be more a reasonable forward ind...

Liar Loans Pop up in Canada's Magnificent Housing Bubble

For a long time, the conservative mortgage lending standards in Canada, including a slew of new ones since 2008, have been touted as one of the reasons why Canada’s magnificent housing bubble, when it implodes, will not take down the financial system, unlike the US housing bubble, which terminated in the Financial Crisis.

Canada is different. Regulators are on top of it. There are strict down payment requirements. Mortgages are full-recourse, so strung-out borrowers couldn’t just mail in their ke...

Here's How Much the Strong Dollar Hurts American Companies (Bloomberg)

American companies had a rough start to 2015 as they watched profits from overseas subsidiaries slide. Exactly how much blame should we assign to the currency markets? Two economists at the Federal Reserve have an idea. 

U.S. corporate profits fell about 1.4 percent in the fourth quarter last year before plummeting 5.2 percent in the first quarter this year, partly driven by a plunge in the amount American companies' foreign affiliates earned. Of the decline in overseas subsidiary profits caused by the appreciating currency and cheaper oil imports, about a third probably came specifically from the gre...

Markets Remain Near and Above, Yesterday's Highs

Tech indices finished strong after they overcame the opening half hour of selling. The Fed statement was greeted favorably, although market breadth is not looking pretty. The Nasdaq still has a distance to travel to make back all of its losses, but has done well to hold up against Semiconductor weakness.


The Semiconductor Index is struggling to make inroads against past losses as the Nasdaq and Nasdaq 100 push respectable gains. I find it hard to see how this scenario can continue, ...

The bull market is coming to an end (Business Insider)

No one knows to what still crazier level this stock market is headed, or what kind of decline – if any ever, the bulls say – it will experience. But we all have our signs and signals that we keep our eyes on, hoping to get the drift in time.

No one wants to go through another crash like the last three (1987, 2000, and 2008 which all occurred during my investing years) with any significant amount money tied up in stocks (not to speak of bonds).

Baxter Int. (BAX) is splitting off its BioSciences division into a new company called Baxalta. 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.
