Perception affects how efficient a dweller is while working in the water treatment and water purification facilities, chances of finding locations when exploring the wasteland, and the speed of the critical hit arrows. It can be increased on different dwellers by assigning them to the armory.
Fallout: The Roleplaying Game[]

Perception's only derived statistic is a character's Initiative which is added with Agility. Perception is also used as the default for skill tests involving Energy Weapons, Explosives, Lockpick, and Pilot (the most skills of any primary stat).
Perception-based perks[]
Fallout: The Board Game[]
Unlike other Fallout games, Perception is not treated as a variable ranging from 1 to 10, but instead as a token that can be obtained at the start or when leveling up. A player character with the Perception token gets free rerolls during certain tests, as well as during fights if equipped with a Perception-based weapon.
The ghoul player character always begins the game with Perception. During any Perception test or fight, Calmex or Mentats can be used to gain one free hit.
