Facilitatory priming of scene layout depends on experience with the scene.

Facilitatory scene priming is the positive effect of a scene prime on the immediately subsequent spatial processing of a related target, relative to control primes. In the present experiments, a large set of scenes were presented, each several times. The accuracy of a relational spatial-layout judgment was the main measure (which of two probes in a scene was closer?). The effect of scene primes on sensitivity was near zero for the first presentation of a scene; advantages for scene primes occurred only after two or three presentations. In addition, a bias effect emerged in reaction times for novel scenes. These results imply that facilitatory scene priming requires learning and is top-down in nature. Scene priming may require the consolidation of interscene relations in a memory representation.
