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

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.

Abenomics Keeps Sputtering – What To Do?

We have frequently discussed the nonsensical attempt by Japanese prime minister Shinzo Abe and BoJ governor Haruhiko Kuroda to print and spend Japan back to prosperity in these pages. By now it is well known that devaluing the yen has not achieved the desired effect, but rather the opposite. Not only have exports not really received the expected boost, but Japan’s trade and current account surplus have decreased markedly, even posting negative numbers for the first time in decades. Of course, c...

Daily Market Commentary: Distribution Returns

Courtesy of Declan.

It was a second day of heavier volume selling in four for the S&P, and the fifth day of distribution since the last accumulation day. The breakout of 1,987 was undercut by Friday's close in addition to a finish below the 20-day MA. Bulls still have room for maneuver with the 50-day MA next in line for a test; even a modest rally Monday would be enough to return the S&P above its breakout.  The higher volume selling is a concern, but not a deal breaker for bulls...yet.


The Nasdaq had a better Friday. While it also suffered a loss, it didn't  undercut its mini-trading range or close below its 20-day MA. It hasn't suffered the same level of distribu...

New Fearmongering Tactics

In the waning moments UK prime Minister David Cameron warns Scots "Leave and You Go Forever".

Actually, the warning probably should be "Stay and you stay forever" because the UK will never allow such a vote again.

Regardless, no country should want to be under the thumb of another.

Polls Diverge

The vote for Scottish independence is now too close to call. In a Scottish Poll Roundup one new poll over the weekend shows the "Yes" vote with a substantial 54-46 lead, but most po...

Option Review

Big Prints In VIX Calls

The CBOE Vix Index is in positive territory on Friday morning as shares in the S&P 500 Index move slightly lower. Currently the VIX is up roughly 2.75% on the session at 13.16 as of 11:35 am ET. Earlier in the session big prints in October expiry call options caught our attention as one large options market participants appears to have purchased roughly 106,000 of the Oct 22.0 strike calls for a premium of around $0.45 each. The VIX has not topped 22.0 since the end of 2012, but it would not take such a dramatic move in the spot index in order to lift premium on the contracts. The far out-of-the-money calls would likely increase in value in the event that S&P500 Index stocks slip in the near term. The VIX traded up to a 52-week high of 21.48 back in February. Next week’s release of the FOMC meeting minutes f...

Making Sense of Bitcoin

Making Sense of Bitcoin

By James Black at International Man

Despite the various opinions on Bitcoin, there is no question as to its ultimate value: its ability to bypass government restrictions, including economic embargoes and capital controls, to transmit quasi-anonymous money to anyone anywhere.

Opinions differ as to what constitutes "money."

The English word "money" derives from the Latin word "moneta," which means to "mint." Historically, "money" was minted in the form of precious metals, most notably gold and silver. Minted metal was considered "money" because it possessed luster, was scarce, and had perceive...

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...
