Event-Related Potentials in Detection of Deception

Event - Related Potentials on the Application of Deception Detection in the Simulation of Concealing Cases

This study used Event-related Potentials (ERPs) to examine the difference between three issue types (related, foil, and unrelated issues) and two reaction types (honesty and deception reaction). This was a subject-in design. Two sets of data were collected. First, the behavior data showed that the reaction time of the deception was 200ms slower than that of honesty, and the decreasing order of ...

Detection of nonlinear event-related potentials.

The methods used to evaluate event-related potentials (ERPs) are generally insensitive to nonlinear responses. Our goal was to show that nonlinear ERPs could be detected using recurrence analysis (RA). When fixed-phase sine signals were added to baseline electroencephalograms (EEGs), the added linear determinism was detected by signal averaging, as expected, and by RA. However, when nonlinear d...

EEG event-related potentials and signal detection.

The purpose of this study was to determine whether certain previously reported relationships between event-related potentials and measures of signal detection performance occur in vigilance as well as psychophysical settings. In the course of the study, evidence was found which challenges previously proposed psychological correlates of "P300". EEG was recorded while 15 subjects carried out a 40...

Changes of Brain Potentials to Event Experience in Detecting Deception

Materials: The 3D visual display was presented through an head-mounted display with resolution of 800 × 600 pixels with a dual monitor. GTA_SA (a computer game published by Rockstar Games) was used as the virtual environment (VE). The P300-based guilty knowledge test (GKT) is a test that uses the P300 amplitude as an index of actual recognition of concealed information (Rosenfeld et al., 2007)....
