Lying upside-down: Alibis reverse cognitive burdens of dishonesty

Area of Science:

• Cognitive Psychology
• Neuroscience
• Forensic Psychology

Background:

• Cognitive processes in dishonesty involve inhibiting honest responses.
• Behavioral measures like response times reflect these cognitive operations.
• False alibis may significantly impact these underlying cognitive mechanisms.

Purpose of the Study:

• To investigate the impact of explicit false alibis on cognitive processes of dishonesty.
• To determine if false alibis can alter behavioral indicators of deception.
• To explore the mechanisms by which false alibis affect cognitive operations.

Main Methods:

• Controlled experimental setup with participants performing tasks.
• Introduction of a false alibi stating alternative actions to be pretended.
• Computer-based inquiry measuring response initiation and execution.
• Distractor stimuli used to investigate response activation.

Main Results:

• False alibis reduced and reversed typical behavioral effects of dishonesty.
• Experiments demonstrated altered response initiation and execution.
• Follow-up investigations suggested automatization of dishonest response retrieval or honest response inhibition.

Conclusions:

• False alibis can entirely override actual activities.
• This finding poses a significant limitation for cognitive lie detection approaches.
• The study highlights the profound impact of fabricated narratives on cognitive deception processes.
