How to Spot Psychopaths: Speech Patterns Give Them Away - And You See Them Every Day In All Walks Of Life...And Not At All Necessarily Murderers Per Se...

Psychopaths are estimated to make up 1 percent of the
population and up to 25 percent of male offenders in federal
correctional settings.

NEW YORK — Psychopaths are known to be wily and manipulative, but even
so, they unconsciously betray themselves, according to scientists who
have looked for patterns in convicted murderers' speech as they
described their crimes.
The researchers interviewed 52 convicted murderers, 14 of them ranked
as psychopaths according to the Psychopathy Checklist-Revised, a 20-item
assessment, and asked them to describe their crimes in detail.
Using
computer programs to analyze what the men said, the researchers found
that those with psychopathic scores showed a lack of emotion, spoke in
terms of cause-and-effect when describing their crimes, and focused
their attention on basic needs, such as food, drink and money. [

While we all have conscious control over some words we use,
particularly nouns and verbs, this is not the case for the majority of
the words we use, including little, functional words like "to" and "the"
or the tense we use for our verbs, according to Jeffrey Hancock, the
lead researcher and an associate professor in communications at Cornell
University, who discussed the work on Monday (Oct. 17) in Midtown
Manhattan at Cornell's ILR Conference Center.
"The beautiful thing about them is they are unconsciously produced," Hancock said.
These unconscious actions can reveal the psychological dynamics in a
speaker's mind even though he or she is unaware of it, Hancock said.
What it means to be a psychopath
Psychopaths make up
about 1 percent of the general population
and as much as 25 percent of male offenders in federal correctional
settings, according to the researchers. Psychopaths are typically
profoundly selfish and lack emotion. "In lay terms, psychopaths seem to
have little or no 'conscience,'" write the researchers in a study
published online in the journal Legal and Criminological Psychology.
Psychopaths are also known for being cunning and manipulative, and they
make for perilous interview subjects, according to Michael Woodworth,
one of the authors and a psychologist who studies psychopathy at the
University of British Columbia, who joined the discussion by phone. [
Criminal Minds Are Different From Yours]
"It is unbelievable," Woodworth said. "You can spend two or three hours and come out feeling like you are hypnotized."
While there are reasons to suspect that psychopaths' speech patterns
might have distinctive characteristics, there has been little study of
it, the team writes.
How words give them away
To examine the emotional content of the murderers' speech, Hancock and
his colleagues looked at a number of factors, including how frequently
they described their crimes using the past tense. The use of the past
tense can be an indicator of psychological detachment, and the
researchers found that the psychopaths used it more than the present
tense when compared with the nonpsychopaths. They also found more
dysfluencies — the "uhs" and "ums" that interrupt speech — among
psychopaths. Nearly universal in speech, dysfluencies indicate that the
speaker needs some time to think about what they are saying.
With regard to psychopaths, "We think the 'uhs' and 'ums' are about putting the mask of sanity on," Hancock told LiveScience.
Psychopaths appear to view the world and others instrumentally, as
theirs for the taking, the team, which also included Stephen Porter from
the University of British Columbia, wrote.
As they expected, the psychopaths' language contained more words known
as subordinating conjunctions. These words, including "because" and "so
that," are associated with cause-and-effect statements.
"This pattern suggested that psychopaths were more likely to view the
crime as the logical outcome of a plan (something that 'had' to be done
to achieve a goal)," the authors write.
And finally, while most of us respond to
higher-level needs, such as family,
religion or spirituality, and self-esteem, psychopaths remain occupied
with those needs associated with a more basic existence.
Their analysis revealed that psychopaths used about twice as many words
related to basic physiological needs and self-preservation, including
eating, drinking and monetary resources than the nonpsychopaths, they
write.
By comparison, the nonpsychopathic murderers talked more about
spirituality and religion and family, reflecting what nonpsychopathic
people would think about when they just committed a murder, Hancock
said.
The researchers are interested in analyzing what people write on
Facebook or in other social media, since our unconscious mind also holds
sway over what we write. By analyzing stories written by students from
Cornell and the University of British Columbia, and looking at how the
text people generate using social media relates to scores on the
Self-Report Psychopathy scale. Unlike the checklist, which is based on
an extensive review of the case file and an interview, the self report
is completed by the person in question.
This sort of tool could be very useful for law enforcement investigations, such as in the case of
the Long Island serial killer,
who is being sought for the murders of at least four prostitutes and
possibly others, since this killer used the online classified site
Craigslist to contact victims, according to Hancock.
Text analysis software could be used to conduct a "first pass,"
focusing the work for human investigators, he said. "A lot of time
analysts tell you they feel they are drinking from a fire hose."
Knowing a suspect is a psychopath can affect how law enforcement conducts investigations and interrogations, Hancock said.

Psychopaths: how can you spot one?
We think of psychopaths as killers, alien, outside society. But, says the
scientist who has spent his life studying them, you could have one for a
colleague, a friend – or a spouse (or rabbi)...
The Mask of Sanity: An Attempt to Clarify Some Issues About the So-Called Psychopathic Personality is a book written by American
psychiatrist Hervey M. Cleckley,
first published in 1941, describing Cleckley's clinical interviews with
patients in a locked institution. The text is considered to be a
seminal work and the most influential clinical description of
psychopathy in the twentieth century. The basic elements of psychopathy outlined by Cleckley are still relevant today.
[1] The title refers to the normal "
mask" that conceals the
mental disorder of the psychopathic person in Cleckley's conceptualization.
[2]
Cleckley describes the psychopathic person as outwardly a perfect
mimic of a normally functioning person, able to mask or disguise the
fundamental lack of internal personality structure, an internal chaos
that results in repeatedly purposeful destructive behavior, often more
self-destructive than destructive to others. Despite the seemingly
sincere, intelligent, even charming external presentation, internally
the psychopathic person does not have the ability to experience genuine
emotions. Cleckley questions whether this mask of sanity is voluntarily
assumed to intentionally hide the lack of internal structure, but
concludes it hides a serious, but yet imprecisely unidentified, semantic
neuropsychiatric defect.
[3]
Six editions of the book were produced in total, the final shortly
after his death. An expanded fifth edition of the book had been
published in 1976 and was re-released by his heirs in 1988 for
non-profit educational use.
