About

All experiments were carried out at the City College of New York by Dr Jens Madsen and Dr Lucas Parra.
Subjects were seated comfortably in a sound-attenuated booth with white fabric walls and normal ambient LED lighting around, and all data acquisition devices were securely and safely attached to participants.
They watched the videos on a 27” monitor approximately 60 cm from the subject, while audio was delivered through stereo speakers placed next to the monitor and separated by 60° from the subject, as shown in the figure.
