Brain Electrical Oscillations Signature (BEOS) Profiling Workshop
Brain Electrical Oscillations Signature (BEOS) Profiling Workshop at
Gujarat Forensic Sciences University, Gandhinagar
Institute of Behavioural Science, January 8 - 10, 2016
National Workshop on “Extraction of Information from Suspects & Accused for Forensic Applications”
Neurocognitive processes of retrieval from memory in the brain of an individual can be monitored, while he is presented with information that may facilitate or cue such retrieval. Retrieval in knowing and remembering has significantly different neural activation patterns. The process of remembrance of participation in an activity, if present, can be automatically elicited, by cueing its retrieval by presenting a related piece of information. Knowing on the other hand may be purely conceptual, which one acquired without any experiential participation.
Sequentially cueing a person by presenting relevant information as probes, facilitate remembrance of the past episodes to occur, if he has participated in them. The probes trigger automatic retrieval or remembrance of the experiences, one has acquired through participation, without needing any behavioural or oral responses. The BEOS system records multichannel EEG from the scalp. Changes in the EEG signals related to recognition of each probe, presence of novelty or familiarity effects of the probes, if any, their semantic processing effects, accessing source memory and inward direction of attention, their emotional effects, and recreation of sensory – motor imageries, are identified. The BEOS system determines the statistical significance of each response/change before its presence is identified and interpreted. The processing effects, seen as frequency and time domain responses in the electroencephalograph of the individual and their topographic patterns, differentiate between presence and absence of the neural process of remembrance taking place. Remembrance cued by a probe indicates the remembrance of ‘Experiential Knowledge’ of the incidence or activity acquired through participation, referred by the probe presented. The BEOS system generates automatically interpreted results of the neural responses to each probe presented, to the examiner for further formulation of the case.
The Brain Electrical Oscillations Signature (BEOS) profiling technique allows testing different forensic formulations or possibilities, which an investigator may consider. The profile elicited using BEOS indicates the specific actions that the individual would have carried out. The profile helps to know if the person had actually indulged in an act, the specific roles carried out by him, or if he were only a witness. The test elicits information on the specific role carried out by each suspect-person, including what a suspect may claim. Several hundreds of cases have been already successfully investigated using the BEOS profile test. There have been several dozens of cases, in which the test findings have helped further progress in the investigations by helping in finding primary evidences, which could resolve the case.
The three days BEOS Workshop will be held in early January 2015 (January 8 - 10) at GFSU, Gandhinagar. The workshop will be conducted by eminent scientists and investigators, who have worked on BEOS in several cases and helped to find solutions in complex investigations. The workshop will impart knowledge of the scientific basis of the method and train participants in the particular interviewing methods used and designing the probes.
The workshop is open to all investigative personnel, professionals from legal system, and scientists associated with forensic investigations, neuro cognitive research and teaching. The fee for each participant of the workshop is Rs.5000/-. Limited accommodation is available at the University (accommodation charges extra).
