The Indian Police JournalSummary: Brain Electrical Oscillation Signature Profiling (BEOS) is a neuro-cognitive indicator which establishes whether a memory or remembrance of an experience is present when cued using probes. BEOS measures the autobiographical memory of a certain incident that can be provoked through the use of probes presented about that incident. The process of remembering an incident is different from the process of knowing the same event. Therefore, BEOS uses this principle to gain experiential knowledge, which is achieved through the first-hand experience of that event rather than the memory of that event. In India BEOS is used as an instrument that assists in forensic psychological investigation. The expert testimony through the result generated by BEOS is used as corroborative evidence. Even after validation studies, BEOS has come under intense scrutiny. This study has attempted to examine the effect of repetition of same probes on the Experiential Knowledge (EK).There were three trials for the same probe on each participant with an array of unending EEG(Electroencephalogram) recordings in each session. This recorded information later was used to generate a report using Neuro Signature System (NSS) for each session. The presence of EK signifies that an individual had previously experienced the incident indicating their participation. The objective of this study was to examine the effect of repetition of same probes on the EK of that incident throughout the three trials. On analysing and comparing the reports generated for each participant, EK in all the three trials existed for similar probe numbers. Further analysis indicated that there is no significant difference in the EK generated during the three trials. That is the experiential knowledge does not improve or decrease with repetition of the probes. – Reproduced
