Abstract

Forensic brainwave analysis (FBA) is a relatively new paradigm and objective tool aimed at detecting concealed information in the brain. It is based on event-related potentials in response to visual or auditory stimuli. Of particular interest is the P300 brainwave elicited after a person has been shown information of particular significance which only the perpetrator would know. An extended version of the P300 test – brain fingerprinting – has been used by its developer, Dr Larry Farwell, in several high-profile cases in the USA. Farwell claims 100% accuracy. A UC-based team of Robin Palmer and Debra Wilson (School of Law), myself (NZBRI, ECE, Psychology), and Ewald Neumann (Psychology), are looking closely at (i) independent lab- and field-based studies to confirm the accuracy of brain fingerprinting, (ii) improve the technique, and (iii) bringing FBA into NZ to improve crucial aspects of criminal justice.


We have completed two studies aimed at confirming the ability of brain fingerprinting to accurately determine the ground truth in (1) 28 psychology students on real-life incidents and (2) 17 ex-prisoners recruited via the Salisbury Street Foundation half-way house. In this talk I will overview the brain fingerprinting technique and outline the results from, and implications of, our two studies.
