Film Production Parameters for Neurometrics
The following film production parameters for GSR studies provide a practical overview of how GSR data can inform creative decisions throughout the filmmaking process, from narrative structure and visual composition to sound design and editing rhythm. Organized by key production elements, it links each parameter to a testable hypothesis, potential physiological indicators, and the resulting impact on production.
