## Scary Movies Use Visual Tricks
Horror films use visual tricks to build unease and frighten audiences through deliberate attention shifts.
## The Hereditary Scene
In 'Hereditary', Peter wakes up disoriented as gasps echo from the audience, then sees his possessed mother on the ceiling.
## Inattentional Blindness
Your visual system misses details when attention is elsewhere, like the invisible gorilla in the basketball experiment.
## Change Blindness
Directors use change blindness to hide transformations, like Janet morphing into an old man in 'The Conjuring 2'.
## Eyeline Match
Directors use eyeline matches to guide attention, like Bathsheba appearing above a wardrobe in 'The Conjuring'.
## Visual Search
The opening of 'It Follows' forces viewers to scan for threats, creating tension through uncertainty.
## Fovea and Peripheral Vision
Your fovea processes fine detail, while peripheral vision detects motion but not detail, creating a gap between detection and identification.
## Pareidolia in Horror
Horror films use pareidolia to create faces where none exist, like in 'Midsommar' and 'The Night House'.
## Why Horror Works
Directors exploit visual system gaps to create tension between perception and recognition, making the audience feel uneasy until the reveal.
## Key takeaway

Horror movies use visual tricks like inattentional blindness and peripheral vision to build tension without the audience noticing threats until the final reveal.
