Interview Lab Flash Cards
Participants:
How many? How were they recruited
2 participants
Recruited through opportunistic sampling
What was the research design?
● Qualitative
● Semi-structured interview
● Lab setting
What were the roles in the research teams, and what did each role do?
2 x timers
■ Recorded the amount of time the interviewee spoke throughout the interview to create an average
2 x self-adaptor gesture observers
■ Took a tally of how many self-adaptor gestures were observed and what the individual gesture appeared like
■ Watched the video several times and then averaged out the number of gestures witnessed
2 illustrator gesture observers
■ Took a tally of how many illustrator gestures were observed and what the individual gesture appeared like
■ Watched the video several times and then averaged out the number of gestures witnessed
What is a self-adaptor gesture?
gestures of self-contact that are assumed to satisfy bodily or self-comforting needs
What is an illustrator gesture?
hand gestures that modify or supplement what is being said verbally
How did our group achieve inter-rater reliability?
two people were allocated to each role; their observations were conducted independently. Results were then compared to ensure agreement between observers.
How was the gesture rate calculated?
● converted the total talk time into seconds
● divided the total number of self-adaptor gestures by the talk time in seconds, and the total number of illustrator gestures by the talk time in seconds
● multiplied these results by 60 to get the most accurate rate of gestures per minute
We calculated the gesture rate differently than instructed. Why ?
The way we calculated gesture rate provided a more accurate result.
If we had divided the number of gestures by the number of minutes spent talking (as instructed), we would have had a less accurate result, because there are only 60 seconds in a minute as opposed to 100.
illustrator gesture is also called ______
lexical gesture
What are two approaches for increasing cognitive load for deception detection?
Imposing cognitive load approach; strategic questioning approach
What is the imposing-cognitive-load approach?
Aims to make the interview setting more difficult for interviewees
The imposing-cognitive load approach is predicated on the supposition that…
Lying is more cognitively demanding than telling the truth (Vrij et al., 2008)
Why is lying more cognitively demanding than truth telling? (6pts)
• Liars are less likely to take their credibility for granted (they have to work harder to come across as honest by monitoring and controlling their behaviour which takes more mental effort)
• liars tend to monitor the reactions of those they’re lying to and make constant assessments as to whether their lie is “working”
• they have to constantly work on playing a role
• they have to suppress the truth and also create a story
• activation of a lie is more deliberate/intentional, thus requiring more mental effort
• liars may not be able to cope with increased demands when cognitive load is raised, which investigators may exploit
The strategic questioning approach is predicated on the finding that liars… because…
Liars prepare because planning makes lying easier (Hartwig et al., 2007) provided the liars can correctly anticipate the interrogators questions (Vrij et al., 2011)
What do our results mean that we can predict about deceptive accounts?
That liars will use gestures more than someone that is telling the truth, especially self-adaptive gestures.
