Expertise and the width of the visual filter in fingerprint examiners

Abstract

Methods:! • We tested 4 Experts and 4 age-matched novice for three 90 minute sessions. • Face and fingerprint trials were intermixed. • EEG data was collected at 1000 Hz and bandpass filtered between .1 and 30 Hz. • We used 32 channels and removed eye artifacts using the EEGLab toolbox (Delorme, A. & Makeig, S., 2004). • Masking noise was generated by bandpass filtering white Gaussian noise with a 2 octave passband and presented additivity on a gamma-calibrated monitor at 120 Hz. • Accuracy was computed at each noise frequency band and plotted against the center frequency.
