Interactive Entertainment vs. Passive Viewing: The Cognitive Science of Multimodal Trailers

Human beings did not evolve to experience the world through isolated rectangular glowing screens. In physical reality, every major sensory event is multimodal: when thunder strikes, you see the lightning flash, hear the acoustic blast wave, and feel the ground vibrate through your soles.

When all three sensory channels coincide within an 80ms temporal window, the midbrain's superior colliculus experiences a neurological phenomenon known as 'superadditive response'—the neural firing rate exceeds the sum of the individual visual and auditory responses combined.

Galvanic Skin Response and Emotional Arousal

In biometric testing measuring viewer skin conductance and pupil dilation, participants watching an Aura trailer exhibited 42% higher galvanic skin response peaks during climactic action beats compared to participants watching identical video footage without tactile feedback. Touch transforms viewing into a physical memory.
