Neuro-psychological assessment of the suspect by applying Brain electrical oscillation signature profiling (Brain mapping)test to verify BEOS principle. BEOS test is applicable in forensic field for detection of a person as suspect, accused, witness or complainant. BEOS is based on EEG and its principle is neuro-psychology. Neuro-psychological criteria of BEOS system contains Experiential Knowledge (EK), Primary processing (PP), Encoding (EN), Emotional Response (ER), Activation Suppression (AS), Inattention (IN) ; etc. “32” electrodes EEG cap to be attached to a suspect and REM electrodes for rotatory eyes moment to be attached. An EEG gel to be fill for better conductivity. Civil and criminal cases examined on BEOS system. As per NHRC guidelines a person willingly gave written consent to undergo for BEOS test as well as person’s jurisdictional court order to conduct a BEOS test is mandatory. Case related audio-visual pre-recorded probes presented to the suspect. Probes framed as neutral, general neutral and relevant point of view. A suspect has to seat in isolated room and he need not to give answer to the presented probes. “Right to remain silent” these constitutional rights are safe for suspect. BEOS system does automatic EEG analysis and generates result in the form of Experiential Knowledge, Primary processing, Encoding, Emotional Response, Activation Suppression, Inattention.
Around 1420 sample of probes taken for neuro-psychological assessment. U/s: 302 of IPC’s real cases were taken and four person examined. Changes in the different frequency bands have different meaning in terms of cognitive and neuro psychological processing. In all four person’s BEOS automated result, i found Experiential Knowledge, Primary processing, Encoding, Emotional Response, Activation Suppression, Inattention shows different sum of digits. On that bases my first hypothesis depict wrong because BEOS is not analyzing total result. Result depends on person’s fact of story and his involvement in the offense and these makes difference in the result of EK, PP, EN, ER, A Supp, and Inattention. Sum of four person’s result percentile shows above 95% suspect was aware during the BEOS test, so my second hypothesis “BEOS principle is neuro-psychology, it is baseless principle; which Ho is rejected because suspect was neuro-psychologically aware during BEOS test so that their results of EK, PP, EN, ER, A Supp, Inattention counted different values as per their involvement. NABL Scope of Accreditation report mentioned that BEOS test is for verification of veracity of statement of the suspect, accused, witness, complainant and victim. BEOS instrument’s range of testing and limits of detection is .99 (200). These research supports NABL scope report of BEOS range testing limits and makes confirmation that BEOS principle is neuro-psychology which is true.
