1 Favorable and unfavorable conditions depend upon the sense being used to make the check. For example, bright light might increase the DC of checks involving sight, while torchlight or moonlight might give a penalty. Background noise might reduce a DC involving hearing, while competing odors might penalize any DC involving scent.
2 As for unfavorable conditions, but more extreme. For example, candlelight for DCs involving sight, a roaring dragon for DCs involving hearing, and an overpowering stench covering the area for DCs involving scent.

Your senses allow you to notice fine details and alert you to danger. Perception covers all five senses, including sight, hearing, touch, taste, and smell.

Check

Perception has a number of uses, the most common of which is an opposed check versus an opponent's Stealth check to notice the opponent and avoid being surprised. If you are successful, you notice the opponent and can react accordingly. If you fail, your opponent can take a variety of actions, including sneaking past you and attacking you.

Perception is also used to notice fine details in the environment. The DC to notice such details varies depending upon distance, the environment, and how noticeable the detail is. The following table gives a number of guidelines.

Action

Most Perception checks are reactive, made in response to observable stimulus. Intentionally searching for stimulus is a move action.

Try Again

Yes. You can try to sense something you missed the first time, so long as the stimulus is still present.

Special

Race Elves, half-elves, gnomes, and halflings receive a +2 racial bonus on Perception checks. Creatures with the scent special quality have a +8 bonus on Perception checks made to detect a scent. Creatures with the tremorsense special quality have a +8 bonus on Perception checks against creatures touching the ground and automatically make any such checks within their range.

Familiars A spellcaster with a hawk or owl familiar gains a +3 bonus on Perception checks. If you have the Alertness feat, you get a +2 bonus on Perception (and Sense Motive) checks.

FYI: Just so you know...
The Trap Spotter rogue talent is a good way to gain an auto-spot ability for traps in the game. Normally, you can't autospot traps like this. A player has to specifically state that they're looking for traps.
Get Organized!

The following information is not official in terms of general campaign usage. It is copied from the Pathfinder Society Organized Play FAQ section of the Paizo website because we thought it might be helpful information for a player or GM in adjudicating common problems or questions. Usage is up to the GM of your game.

What does a deaf PC (or other creature) need to do in order to read lips?

Any PC may learn to read lips with a rank in Linguistics as if they had learned a new language. When reading the lips of a speaking creature within 10 feet in normal lighting conditions, the reader need not make any skill checks. In situations of dim lighting, extreme distances, or to read the lips of someone trying to hide their words from the reader, the reader must make Perception checks (DC determined by the GM based on the situation). A lip reader may only understand spoken words in a language it knows.
