A method for correlating Galvanic Skin Response (GSR) signals from multiple users watching the same content to identify scenes of interest in such content includes filtering GSR signals from each user by subtracting consecutive GSR signal samples from each other. The user reaction portion and baseline portion of the GSR signals for the users are collectively optimized to recover non-zero user responses for the users. The locations in the content having the non-zero responses for the users are then identified as the scenes of interest in such content for the users.
