This study shows memory and encoding related multifaceted electroencephalographic response (MERMER) accurately detects concealed information about past events. MERMER testing reliably identified participants who experienced an event with high statistical confidence.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Forensic Science

Background:

  • The ability to detect concealed information is crucial in legal and investigative contexts.
  • Existing methods for detecting concealed information face challenges in accuracy and reliability.
  • The P300 component of brain activity has shown potential in identifying relevant information.

Purpose of the Study:

  • To evaluate the accuracy and reliability of the memory and encoding related multifaceted electroencephalographic response (MERMER) technique.
  • To determine if MERMER can detect information about experienced events, even when subjects attempt to conceal it.
  • To assess the potential of MERMER as an investigative tool in criminal cases.

Main Methods:

  • Developed stimulus sets (Probes, Targets, Irrelevants) based on interview information.

  • Presented stimuli visually to subjects, including those who participated in an event and those who did not.
  • Recorded and analyzed non-invasive scalp electrical brain responses (MERMERs) using bootstrapping for statistical analysis.

    • Main Results:

    • MERMERs were elicited by Probe stimuli exclusively in subjects who had experienced the event.
    • Target stimuli elicited MERMERs in all subjects, while Irrelevant stimuli did not elicit responses.
    • The MERMER technique correctly identified information presence or absence in all six subjects with high statistical confidence (99.9% in five cases, 90.0% in one).

    Conclusions:

    • MERMER testing demonstrates high accuracy and reliability in detecting concealed information about past events.
    • The technique successfully differentiates between subjects who possess specific knowledge and those who do not.
    • MERMER technology holds significant potential for application as a future investigative tool in forensic and criminal investigations.
