Study Notes
Polygraph Test Accuracy and Alternatives
- Patrick and Iacono found that original polygraph examiners are often influenced by extra-polygraph cues.
- Most field studies of polygraph accuracy have used confessions to establish guilt or innocence.
- The Comparison Question Test is more effective at detecting guilty suspects, while the Concealed Information Test is more effective at detecting innocent suspects.
- The Concealed Information Test is vulnerable to falsely classifying guilty suspects as innocent and falsely classifying innocent suspects as guilty.
- Freya used a physical countermeasure by biting her tongue, while Mila used a mental countermeasure by counting backward by 7 from a number greater than 200.
- Most knowledgeable scientists have negative beliefs, and the general public has positive beliefs about the accuracy of the Comparison Question Test.
- Polygraph evidence is never admissible in Canadian criminal courts of law.
- The Supreme Court of Canada ruled in R. v. Beland that polygraph evidence should not be admitted in court to help determine truthfulness.
- The technique not used as a method of detecting deception is the Thematic Apperception Test (TAT).
- ERPs measure changes in electrical patterns related to presentation of a stimulus by placing electrodes on the scalp.
- The event-related potential known as P300 occurs in response to significant stimuli that occur infrequently.
- The appeal of using a brain-based lie-detection approach is that researchers hope it measures deception instead of emotional arousal.
Deception and Malingering: Key Concepts
- Lie bias refers to the tendency to judge more messages as truthful than deceptive.
- Training programs for professionals should focus on teaching both deception cues and truthfulness cues to counteract lie biases.
- Factitious disorder consists of intentionally produced or falsified symptoms in the absence of obvious external rewards.
- Munchausen syndrome by proxy is a rare factitious disorder in which a person intentionally produces an illness in their child.
- Malingering involves intentional symptoms and external incentive.
- The opposite of malingering is called defensiveness, which involves the conscious denial or extreme minimization of physical or psychological symptoms.
- Richard Roger provided three explanatory models of malingering, with the pathogenic model assuming that people are motivated to malinger because of an underlying mental disorder.
- In Richard Roger’s criminological model of malingering, people are assumed to be motivated to malinger because of an underlying mental disorder.
- The most common research design used to study malingering is the simulation design.
- A study of malingering that uses a group of people with the mental disorder and malingers the symptoms is known as the clinical experimental group.
- A study of malingering that has the mental disorder being studied but does not attempt to malinger symptoms is known as the clinical control group.
- A study of malingering that uses a group of people who do not have the mental disorder being studied and malingers the symptoms is known as the non-clinical experimental group.
Deception Detection and Expert Testimony Study Summary
- McCabe, Castel, and Rhodes (2011) conducted a study on the influence of expert evidence on verdicts in a mock juror trial.
- An expert testified about increased activation of the frontal brain areas when the defendant denied killing his wife and her lover, leading to the highest percentage of guilty verdicts.
- Different non-verbal cues, such as increased facial temperature, blood pressure, and averted gaze, were used as expert evidence in the study.
- The study found that smiling, gaze aversion, self-manipulations, and blinking were not consistently indicative of deception.
- The most common stereotype about liars was that they avoid eye contact.
- Avoidance of eye contact, deception detection being easy, and liars fidgeting more than truth-tellers were listed as myths for detecting deception.
- Research by Matsumoto, Hwang, Skinner, and Frank (2011) recommended paying attention to micro facial expressions during interrogations.
- Voice pitch was found to be the verbal indicator most strongly associated with deception.
- Deception judgments were found to depend more on the liar than the judge.
- Truth-tellers were found to be less likely to change their stories, contrary to popular belief.
- A meta-analysis by Aamodt and Custer (2006) found that the average accurate rate for detecting deception by professional lie catchers was around 55%.
- Police officers were found to be less accurate at detecting low-stakes lies compared to high-stakes lies.
