Esto es algo que ya postee antes pero se reactualiza ahora cuando aparece una entrevista al acusado de asesinar a Angeles Rawson.
Los aspectos ecntrales son el discurso medido, guionado, la utilización de verbos más frecuenets en relación con actos, habalr en pasado, en alguna medida despegandose de la situación, y varias cosas más. Pronto lo extiendo

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. [10 Contested Death Penalty Cases]
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.
