What is a strength of using a semi-structured interview?

How was psychopathy measured?

Personality Checklist revised (PCL-R)

Who created the PCL-R?

Robert HARE

What happened after the interviews?

Narratives were TRANSCRIBED as close to verbatim through content analysis using the W-matrix and DAL

What was the sample?

52 males from Canadian correctional facility

What were the conviction rates?

16% (8) = first degree murder 64% (32) = second degree murder 20% (10) = manslaughter

What was the psychopath to non-psychopath ratio?

14:38

What was the mean age and the range of the age of convicts?

Mean age was 20.8 Range was 14-50

What are the 5 evaluation points of the sample?

- culture bias (ethnocentric) - gender bias (androcentric) - only a specific type of person (volunteer) - social desirability (self-report) - small sample (not rep. = not gen.)

How were participants acquired?

Volunteered

What are strengths of a self-selected sample?

- less chance of attrition (dropping out)

What are the weaknesses of a self-selected sample?

- only attracts a certain type of person - therefore less representative - cannot be generalised

What did the two groups not differ on (Psychopaths vs. Non-Psychopaths)?

- age - amount of time since homicide was committed

What was the first step of the procedure?

Potential participants were asked if they would be interested in taking part in a research study

What was the first stage for those who were interested?

Were asked to complete the PCL-R

What is the PCL-R?

Psychopathy Checklist- Revised

What's a strength of the PCL-R?

- universal = more valid and reliable

What is involved in the PCL-R?

- 20 criteria (rated from 0-2) - maximum score of 40 - 25+ = Psychopath

Who conducted the PCL-R?

extensively trained prison psychologists who were trained in the coding of the PCL-R

How long were the interviews?

25 minutes

How is the procedure unethical?

Participants were deceived on the aim of the study - they were told it was about memory and how well inmates can recall their homicides

What is a strength of the interview?

Verbally explained so that participants can ask questions and understand what they have to do properly

How was the interview recorded?

Audio-taped

What were participants asked to do in the interview?

Describe their homicide in as much detail as possible

Who were participants interviewed by?

two senior psychology graduate students and one research assistant

What is important to note about the interviewers?

they were blind to the psychopathy scores

What is the Wmatrix?

a text analysis tool which compares part of speech to analyse semantic concepts

What is the DAL?

analyses tone of words

What are some results found by the Wmatrix?

psychopaths used approx. twice as many words in relation to basic physiological needs such as eating compared to the controls who focused on social needs such as family

What are some results from the DAL?

psychopaths physiologically distanced themselves from their homicide

What are the results regarding word use?

- psychopaths used roughly 2,200 words and non-psychopaths used roughly 2,500 words - psychopaths used more past tense verbs such as 'stabbed'

What are some conclusions of the study?

- Psychopaths are more likely than non-psychopaths to describe a cause and effect relationship when describing their murders - Psychopaths linguistically frame their homicide as more in the past through using psychologically distant terms

What are some conclusions about psychopaths and language use?

1- tend to view their crimes as the logical outcome of a plan 2- more likely to focus on their own physiological needs 3- less emotional and positive in their speech 4- emotionally detached from their crimes

What are the ethical issues considered in this study?

- full confidentiality was maintained - full informed consent (volunteer) - debriefed verbally at the end of the interview
