Mixed Signals: Preprocessing Psychophysiological Data in Brain Vision Analyzer Psychophysiology manual
Mixed Signals: Preprocessing Psychophysiological Data in Brain Vision Analyzer is a psychophysiology manual for experimental psychologists . Originally compiled by Paul Pfaff at the Experimental Psychopathology and Clinical Psychology lab at Utrecht University , the updated edition of the manual was printed in 2025.
The manual covers the preprocessing of a wide range of psychophysiological data types common in experimental psychology. Specific sections are dedicated to skin conductance response , facial electromyography (EMG), startle EMG, smiling/frowning EMG, and postural sway. Preprocessing steps outlined include baseline correction, filtering, artifact rejection, and signal standardization. Recommendations are provided based on reviews of the latest literature in the field.[ 1] [ 2] [ 3] [ 4] [ 5] [ 6] [ 7]
The publication is part of ongoing open science initiatives in psychology to standardize research procedures in the aftermath of the replication crisis [ 8] and has received positive reviews.[ 9] [ 10]
