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

"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.

Fans of Central Banking Have an Achilles Heel

Courtesy of ZeroHedge. View original post here.

Submitted by Gold Standard Institute.

by Keith Weiner

 

Most of my writing about the gold standard is about how it works, and how the paper dollar standard doesn’t. A casual conversation I had with someone recently underscored that there is an even stronger argument.

Our opponents, those who support central banking and irredeemable paper money, have to make two cases. One is to defend the theory and practice of central banking, that central bankers are wise and honest and that their debt-based paper money works. They have to argue that the dollar does everything you want money to do, such as hold its value, enable proper accounting, encourage savings, support a stable economy, etc. Well, they can go through the moti...

Home Prices Drop in 69 of 70 Chinese Cities; Did the Pool of Greater Fools Run Out?

Courtesy of Mish.

China eased purchase restrictions last month ending its four-year campaign to contain home prices. And what a ridiculous campaign it was. Prices are down less than 1% this month and less then 1% year-over-year.

Bloomberg reports China Home-Price Drop Spreads as Easing Doesn’t Halt Fall.

Prices dropped in 69 of the 70 cities in September from August, the National Bureau of Statistics said in a statement today, the most since January 2011 when the government changed the way it compiles the data. They fell in 68 cities in August.

The central bank on Sept. 30 eased mortgage rules for homebuyers that have paid off existing loans, reversing course after a four-year camp...

World Markets Weekend Update: Selloff Ends, Rally Begins

Courtesy of Doug Short.

In last weekend's update, only one the eight indexes on my watchlist posted a weekly gain. This weekend's numbers have reversed. Seven indexes closed the week with a gain and there were some substantial ones at that. Japan's Nikkei erased the previous week's -5.02% plunge with a 5.22% surge. The S&P 500 finished second with a 4.12% advance. China's Shanghai Composite was the sole loser, down 1.66%.

In fact, the Shanghai Composite remains the only index on the watch list in bear territory -- the traditional designation for a 20% decline from an interim high. The index is down 33.68% from its August 2009 peak. See the table inset (lower right) in the chart below.

Here is a look at 2014 so far....

LUV Options Active Ahead Of Earnings

There is lots of action in Southwest Airlines Co. November expiry call options today ahead of the air carrier’s third-quarter earnings report prior to the opening bell on Thursday. Among the large block trades initiated throughout the trading session, there appears to be at least one options market participant establishing a call spread in far out of the money options. It looks like the trader purchased a 4,000-lot Nov 37/39 call spread at a net premium of $0.40 apiece. The trade makes money if shares in Southwest rally 9.0% over the current price of $34.32 to exceed the effective breakeven point at $37.40, with maximum potential profits of $1.60 per contract available in the event that shares jump more than 13% to $39.00 by expiration. In September, the stock tou...

Sector Detector: Sharp selloff in stocks sets up long-awaiting buying opportunity

Courtesy of Sabrient Systems and Gradient Analytics

Last week brought even more stock market weakness and volatility as the selloff became self-perpetuating, with nobody mid-day on Wednesday wanting to be the last guy left holding equities. Hedge funds and other weak holders exacerbated the situation. But the extreme volatility and panic selling finally led some bulls (along with many corporate insiders) to summon a little backbone and buy into weakness, and the market finished the week on a high note, with continued momentum likely into the first part of this week.

Despite concerns about global economic growth and a persistent lack of inflation, especially given all the global quantitative easing, fundamentals for U.S. stocks still look good, and I believe this overdue correction ultimately will shape up to be a great buying opportunity -- i.e., th...

Goodbye War On Drugs, Hello Libertarian Utopia. Dominic Frisby's Bitcoin: The Future of Money?

Courtesy of John Rubino.

Now that bitcoin has subsided from speculative bubble to functioning currency (see the price chart below), it’s safe for non-speculators to explore the whole “cryptocurrency” thing. So…is bitcoin or one of its growing list of competitors a useful addition to the average person’s array of bank accounts and credit cards — or is it a replacement for most of those things? And how does one make this transition?

With his usual excellent timing, London-based financial writer/actor/stand-up comic Dominic Frisby has just released Bitcoin: The Future of Money? in which he explains all this in terms most readers will have no tr...

Well PSW Subscribers....I am still here, barely.  From my last post a few months ago to now, nothing has changed much, but there are a few bargins out there that as investors, should be put on the watch list (again) and if so desired....buy a small amount.

First, the media is on a tear against biotechs/pharma, ripping companies for their drug prices.  Gilead's HepC drug, Sovaldi, is priced at $84K for the 12-week treatment.  Pundits were screaming bloody murder that it was a total rip off, but when one investigates the other drugs out there, and the consequences of not taking Sovaldi vs. another drug combinations, then things become clearer.  For instance, Olysio (JNJ) is about $66,000 for a 12-week treatment, but is approved for fewer types of patients AND...
