Detecting lies about consumer attitudes using the timed antagonistic response alethiometer.

Area of Science:

• Cognitive Psychology
• Deception Detection
• Psychometric Assessment

Background:

• The Timed Antagonistic Response Alethiometer (TARA) is a validated tool for lie detection based on response latency.
• Prior research demonstrated TARA's efficacy with demographic and religious statements, achieving approximately 80% accuracy.

Purpose of the Study:

• To evaluate the TARA's diagnostic accuracy for detecting deception related to consumer attitudes (branded and generic products).
• To assess the TARA's reliability across different versions and repeated administrations.

Main Methods:

• Participants responded to true-false statements about product attitudes under TARA conditions.
• Experiments involved multiple TARA versions (Exps. 1a, 1b, 1c) and consecutive testing (Exp. 2).

Main Results:

• TARA accuracy generalized well across different versions of the task.
• Maximal accuracy rates exceeded 80%, indicating strong diagnostic potential for attitude deception.
• A slight decrease in accuracy was observed upon repeated testing.

Conclusions:

• The TARA demonstrates significant promise as a lie detection tool for assessing attitudes.
• Its cost-effectiveness, convenience, and diagnostic capability make it a valuable index for deception research.
