What is a psychopath
A term to describe people who show a reduced capacity for moral responsibility and may act extremely selfishly. They seem to lack a conscience and empathy
Aim
To examine whether the language of psychopathic murderers was different to non psychopathic murderers
What were the three language indicators used to analyse psychopathic speech
- An instrumental or predatory view
- Unique material and socio-economic needs
- Poverty of affect
Research method
Self report method which involved face to face semi-structured interviews using open ended questions aka Step-wise interview
Sample
- 52 male murderers
- Prisoners in Canadian prisons
- All had admitted to their crime
- Volunteered for the study
Sampling method
Volunteer sampling
Procedure
- Participants were asked whether they would be interested to take part
- Psychopathy was measured using Hare’s Psychopathy Checklist-Revised and the cut off score was 25
- Participants were then interviewed, they were briefed on the aim and procedure.
- They were audiotaped to describe their homicide offence in as much detail as possible using a standardised procedure known as Step -Wise interview.
- The interviewers were two senior psychology graduate students and one research assistant, all blind to the psychopathy scores of the offenders. Each interview lasted 25 minutes
- Each interview was then transcribed, as close to verbatim. And analysed using text analysis tools: W matrix program, used to analyse parts of the speech. And DAL software to examine emotional properties of the language.
What were the 2 text analysis tools used
- Wmatrix program
- The Dictionary of Affect in Language (DAL) software program
What is the Wmatrix programme
A programme that analysed the body of speech produced by the two groups and tagged parts of speech such as nouns, verbs, adjectives and also semantic concepts such as communication, social actions, time etc
What is the dictionary of affect in language (DAL) software
A programme that was used to examine the emotional properties of the language used
Findings relating to instrumental language analysis
Psychopaths were more likely to describe homicide using subordinating conjunctions. This almost showed a justification for their crimes
Findings relating to socio-economic needs
- Psychopaths used approximately twice as many words relating to basic physiological needs such as food drink or money when describing their crime
- Non-psychopaths used significantly more language relating to social needs such as family and spirituality
Findings relating to poverty of affect
- Psychopaths used more past tense verbs showing how they were more detached from their crimes
- Psychopaths’ language was significantly less fluent
- Psychopaths’ language was less positive and less emotionally intense
Main finding
Psychopathic murderers used less emotive language and ore subordinating conjunctions to justify their murders
Conclusions
- Psychopaths are more likely to view their crime as a logical outcome of a plan than a non-psychopath
- Psychopaths focus more on basic physiological needs than higher level social needs than non-psychopaths
- Psychopaths are more emotionally detached from their crimes
- Psychopaths are less emotional and less positive in their speech
