Full text of study published in: PLOS ONE: Testing the Effectiveness of 3D Film for Laboratory-Based Studies of Emotion.

The authors found little difference in emotional response of watching film clips (not entire films) in 2D versus 3D.

The study had 408 volunteers view selected clips from 4 films in 2D or 3D while hooked up to cardiac monitoring machines. Physiological data was used as a proxy for the viewer’s emotional state.

The British press has concluded this proves that 3D is worthless and announced that all British reporters plan to cover one eye with an eye patch, in their future lives.
