ABSTRACT The feasibility of using Event Related Brain Potentials (ERPs) in Interrogative Polygraphy (“Lie Detection”) was tested by examining the effectiveness Guilty Knowledge Test designed Farwell and Donchin (1986, 1988). subject is assigned an arbitrary task requiring discrimination between experimenter‐designated targets other, irrelevant stimuli. A group diagnostic items (“probes”), which to unwitting are indistinguishable from items, embedded among irrelevant. For subjects who possess...

This contribution presents four results. First, calculations indicate that when examined by the Grassberger-Procaccia algorithm alone, filtered noise can mimic low-dimensional chaotic attractors. Given ubiquity of signal filtering in experimental investigations, this is potentially important. Second, a criterion derived which provides an estimate minimum data accuracy needed to resolve dimension attractor. Third, it shown Eckmann and Ruelle [Physica D 56, 185 (1992)] number points required...

This experiment examined the accuracy and reliability of memory encoding related multifaceted electroencephalographic response (MERMER) technique for detecting information to events subjects have experienced, despite subjects' efforts conceal that knowledge. Information obtained through interviews was used develop stimulus sets consisting words phrases presented visually by computer. Sets were composed three types stimuli: life experience-related (Probes), stimuli subject asked memorize...

Abstract A fundamentally important problem for cognitive psychophysiologists is selection of the appropriate off‐line digital filter to extract signal from noise in event‐related brain potential (ERP) recorded at scalp. Investigators field typically use a type finite impulse response (FIR) known as moving average or boxcar achieve this end. However, can produce significant amplitude diminution and distortion shape ERP waveform. Thus, there need identify more filters. In paper, we compare...

A classification concealed information test (CIT) used the "brain fingerprinting" method of applying P300 event-related potential (ERP) in detecting that is (1) acquired real life and (2) unique to US Navy experts military medicine. Military medicine non-experts were asked push buttons response three types text stimuli. Targets contain known relevant medicine, are identified subjects as relevant, require pushing one button. Subjects told another button all other Probes not subjects....

Farwell in Cogn Neurodyn 6:115-154, (2012) reviewed all research on brainwave-based detection of concealed information published English, including the author's laboratory and field research. He hypothesized that specific methods are sufficient to obtain less than 1 % error rate high statistical confidence, some them necessary. proposed 20 brain fingerprinting scientific standards embodying these methods. documented fact previous data compatible with hypotheses standards. explained why...

This poster will provide an overview of brainwave technology and Alzheimer's disease, with special attention to the P-300 electroencephalic waveform. Currently, most healthcare providers rely on standardized, but subjective cognitive impairment test protocols limited utility. Until recently, there was no objective means diagnosing early prodromal stages dementia short a neuropathological investigation at autopsy. Recently, neuroimaging techniques biomarkers have been used diagnose AD, these...
