Q

are all murders psychopaths

A

No. It is important to see the distinction between the different categories of murder. For example, crimes of passion are rarely associated with psychopaths due to the crime being spontaneous and unplanned.

Q

are all murders psychopaths

A

No. The characteristics of psychopaths often lend themselves to top level positions in business. Statistics suggest that 1% of the population are psychopaths and it is unlikely that the whole prison population is made up of psychopaths.

Q

background to psychopathy + language

A
  • Williamson (1993) analysed the narratives of psychopaths and non-psychopaths and found that psychopathic language may be less cohesive and more incoherent.
  • Porter et al. (2009) – psychopathic offenders x2.5 more likely than non-psychopaths to have successful parole applications, despite being far more likely to reoffend.
  • Cleckley (1976) observed, through case studies, that the discourse of psychopaths was more likely to include a tangential and incoherent quality than non-psychopaths.

Q

aim

A
  • examine the specific qualities of psychopathic language using sophisticated statistical text analysis tools.
  • The researchers examined the language characteristics of psychopaths (in describing their violent crimes) on three major characteristics:
    (i) Their instrumental nature.
    (ii) Their unique material and socioemotional needs.
    (iii)Their emotional deficit

Q

instrumental language

A
  • Psychopaths see opportunity to take things so may use more subordinate conjunctions compared to Non-Psychopaths
  • Subordinate conjunctions show cause and effect and evidence of premeditation (planned their crimes)

Q

emotional deficit

A

Psychopaths have emotional deficits- personally and recognising others emotions - may therefore :
- Use less emotional words
- More disfluency in speech eg. ‘um’ ‘ah’ as they don’t know how to describe events appropriately
- Distancing language as don’t feel responsible for their crimes e.g - past tense and dehumanising ‘the person’ ‘a person’

Q

sample

A
  • 52 male murderers (14 psychopathic, 38 non-psychopathic)
  • Incarcerated in Canadian correctional facilities
  • Had admitted their crime and volunteered for the study
  • Similar mean age (28.9 yrs) in 2 groups & similar in the time since the homicide was committed (11.87 yrs and non-psychopaths, 9.82 yrs).

Q

procedure

A
  1. Psychopathy was measured using Psychopathy Checklist Revised (PCL-R; Hare, 1991, 2003).
  2. Used semi-structured/open-ended interviews (a self-report method) employing the Step-Wise Interview technique
  3. Transcribed narratives & analysed; content analysis using the Wmatrix and the DAL (Dictionary of Affect in Language).
  4. Assessments carried out by trained prison psychologists and researchers experienced in coding the test.
    –>Inter-rater reliability check was conducted on the PCL-R scores – trained graduate student

Q

psychopathy measurement

A

39 prisoners were assessed by Psychologists, 13 prisoners assessed by researchers experienced in coding the test.
- Inter-rater reliability check was conducted on the PCL-R scores – trained graduate student re-coded 10 randomly selected case files.
- 25/40 for the purpose of this study was considered Psychopathic

Q

step wise interview technique

A
  • The steps in this method begin with the most open, least leading, least suggestive form of questioning and, if necessary, proceed to more specific and more leading questioning
  • Used in interviewing victims of crimes (minimise trauma)
  • Also used as a strategy for minimising the effects of leading questions / post event information
18
Q

interviews

A
  • Interviewers= 2x psychology graduates and 1x research assistant
  • Blind to the psychopathy scores of ppts.
  • At the beginning of the interview, the purpose of the study (to examine the manner in which homicide offenders recall their homicide offence) and the procedure were verbally explained.
  • Prisoners were asked to describe the homicides in as much detail as possible
  • Took 25 minutes
  • Were taped
  • Interviews transcribed
  • Analysed using 2x text-analysis tools.
19
Q

analysing interviews - Wmatrix

A
  • W matrix = tool for corpus analysis and comparison
  • Corpus linguistics is the study of language as expressed in speech
  • The speech produced by the psychopaths was compared to all the speech produced by the non-psychopathic killers:
    > Instrumental language analysis i.e. because, since, as, so that.
    > Hierarchy of needs analysis (relating to Maslow’s typology)
    > Temporal representations – use of past , present and future tense in lexical verbs
20
Q

analysing interviews - DAL

A
  • An instrument designed to measure the emotional meaning of words and text
  • Compares individual words to a word list of 8742 words that have been rated by people for their activation evaluation and imagery
21
Q

Results - Instrumental language analysis

A
  • Psychopaths produced more subordinating conjunctions than controls e.g. because, since, as, so that.
  • 1.82% of the language used by Psychopaths were instrumental vs 1.54% for non- Psychopaths
22
Q

Results - Hierarchy of needs analysis

A
  • Psychopaths used approximately twice as many words related to basic physiological needs, including eating, drinking and monetary resources
  • Controls used significantly more language related to social needs, including family, religion and spirituality than psychopaths.
23
Q

Results- Temporal representations of psychopathic and non-psychopathic offenders.

A
  • Psychopaths had 33% more disfluency in speech ‘um’ ‘ah’
  • Psychopaths used more past tense verbs than controls e.g. stabbed.
  • Psychopaths produced a higher rate of articles (a word that is used with a noun to indicate the type of reference being made by the noun- e.g. the ,an ,a) than controls, revealing that their language involved less names of something or someone
24
Q

Results - Emotional deficits

A
  • Initially, no significant differences in the emotional content of language between the two groups in terms of pleasantness, intensity or imagery were found.
  • However further analysis showed psychopathy to be associated with less positive valence and less emotionally intense language
25
Q

conclusions - psychopaths are …

A
  1. More likely than non-psychopaths to describe cause and effect relationships when describing their murder.
  2. More likely to view their crime as a logical outcome of a plan than non-psychopaths.
  3. Focus more on physiological needs than higher level social needs than non-psychopaths.
  4. Are focused on a lower level of necessities in Maslow’s hierarchy of needs than non-psychopaths.
  5. Will linguistically frame their homicide as more in the past and in more psychologically distant terms than non-psychopaths.
  6. Give less emotionally intense descriptions of their crimes and use less emotionally pleasant language than non-psychopaths.
26
Q

further conclusions

A
  1. Psychopathic language is substantially more disfluent than that of non-psychopaths.
  2. Psychopaths describe powerful emotional events (their crimes) in an idiosyncratic manner.
  3. Psychopaths operate on a primitive but rational level.
