Motivation and emotion/Book/2024/Truth serum drugs
What are truth serum drugs, do they work, and how?
Overview
editYou have been convicted of a murder you did not commit. All evidence points to you and your alibi is unprovable. The jury is convinced you are the murderer and a life in prison awaits you. However, a physician offers one last piece of hope to aid in your trial. With your consent, he will administer truth serum. Largely untested and with inconclusive results, the truth serum may not assist in the prosecution.
Do you consent to take the truth serum? Do you believe it will help your case? Will there be adverse effects from the serum? Should the jury take your statement as true? These are all questions that surrounded the initial use of truth serum (Minor., 1995) |
Key Concepts:
- Truth Serum Drugs: Substances intended to enhance truth-telling or reduce resistance to interrogation.
- Motivation and Emotion: Understanding how these drugs interact with cognitive functions related to motivation and emotion.
- Evidence: Analysis of research on the effectiveness and reliability of truth serum drugs
Focus Questions:
1. What does research say about the efficacy of truth serums in eliciting truthful information? 2. What are the primary drugs classified as truth serums and how do they work? 3. How do these drugs affect motivation and emotion during interrogation? 4. What are the ethical considerations surrounding the use of truth serum drugs? |
Efficacy
editDebate over efficacy and whether truth serum drugs provide sound evidence.
Initial use
editRobert Ernest found drugs could lower inhibitions and make subjects more likely to disclose information (Winter et al., 2005)
Modern research
editPotential applications but lack of acceptance and lack of concrete evidence reduces efficacy (Barnwal., 2016)
Primary Drugs
editDrugs that reduce inhibition in various ways
Sodium Pentothal (Thiopental)
editA central nervous system depressant, slows brain activity and reduces inhibition (Fraser et al., 1950)
Scopolamine
editInduced a trance like state called "twilight-sleep" by Dr House. More commonly used to medicate motion sickness, it interferes acetylcholine receptors (Geis et al., 1959)
Sodium Amytal
editSodium Amytal (see figure 1) is similar to sodium pentothal as it is a nervous system depressant. Gained traction in World War 2 as it can be given orally and is easy to mask the flavour (Freedman., 1960)
How Do They Work?
editImpact a number of key psychological processes
Reduced Anxiety and Emotional Barriers
editTypically depresses the central nervous system, reducing inhibition.
Increased Suggestibility
editReduced inhibition means that patients under the effect of truth serum are more likely to be convinced by external cues.
Potential problems around leading questions.
Emotional Detachment
editCan interfere with the patient's motivations, as they may become indifferent to the consequences of their statements.
Ethical Considerations
editMany ethical considerations surround truth serum and the use of truth serum has been outlawed in many countries.
Human Rights Concerns
editInternational legal standards, such as those outlined in the UN Convention Against Torture, prohibit their use (Keller et al., 2004)
Informed Consent
editSubjects under the influence of these drugs may not be fully aware of or able to consent to the interrogation process.
Coercion
editTruth serums can be considered a form of psychological coercion, as they alter mental states and impair decision-making capacities.
Figures
edit- Use figures to illustrate concepts, add interest, and to serve as examples
- Figures can show photos, diagrams, graphs, video, audio, etcetera
- Embed figures throughout the chapter, including the Overview section
- Figures should be captioned (using Figure #. and a caption). Use captions to explain the relevance of the image to the text/
- Wikimedia Commons provides a library of embeddable images
- Images can also be uploaded to Wikimedia Commons if they are openly licensed
- Refer to each figure at least once in the main text (e.g., see Figure 2)
Learning features
editYou decided to take the truth serum in front of the court to attempt to prove your innocence. Scopolamine was used as you drift into a "twilight-sleep" state. In this state you are asked a leading question. Unable to consider your response you reply and add more evidence to your case that suggests you are guilty of the murder.
As psychologists, it's important to understand the dangers of truth serum drugs and the potential ramifications of an incorrect statement. |
Conclusion
edit- The Conclusion is arguably the most important section
- Suggested word count: 150 to 330 words
- It should be possible for someone to only read the Overview and the Conclusion and still get a pretty good idea of the problem and what is known based on psychological science
