With the same anecdote, the present study attempted to reflect the clarity on the issue by taking a paradigmatic move in exploring the psychopathology with the help of Brain Fingerprinting Technique (BFT). BFT computes a mathematical and statistical algorithm for determination of information through presentation of stimuli. This presentation of stimuli leads to generation of P300-MERMER brainwave to determine the information. The same argument of real vs virtual experiential contexts pertaining to certain psychiatric conditions was applied in the present study. With the help of data analysis, it was proven that no biological evidence of fingerprinting with respect to delusional beliefs, perception of auditory stimuli in hallucinatory behaviour and real loss of information in case of dissociative amnesia was observed in the brain. Rather, in first two conditions the mathematical and statistical algorithm computed \u2018information absent\u2019 and in third condition it computed as \u2018information present\u2019 respectively. The above observations helped in substantiating the diagnoses of the patients with scientific sanctity and physiological correlates. The present study could be able to expand the horizon of applications of BFT in few of the psychiatric conditions such as delusional disorders, hallucinatory behaviours, and dissociative amnesia.<\/jats:p>","DOI":"10.1177\/09727531261478463","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T12:11:14Z","timestamp":1789128674000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Exploring Psychopathology with Brain Fingerprinting Technique"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1079-2681","authenticated-orcid":false,"given":"Anand Pratap","family":"Singh","sequence":"first","affiliation":[{"name":"Department of Psychology and Mental Health, Gautam Buddha University, Greater Noida, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5416-0446","authenticated-orcid":false,"given":"Aakriti","family":"Varshney","sequence":"additional","affiliation":[{"name":"Department of Psychology and Mental Health, Gautam Buddha University, Greater Noida, Uttar Pradesh, India"},{"name":"Department of Clinical Psychology, Shanti Home, Advanced De-addiction Mental Health Clinic and Psychiatric Rehabilitation Center, Greater Noida, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,9,11]]},"reference":[{"issue":"4","key":"e_1_3_7_2_2","first-page":"434","article-title":"The brain detector: P300 in the detection of deception","volume":"23","author":"Farwell LA","year":"1986","unstructured":"Farwell LA, and Donchin E.
