The correct answer is priming.  

Priming refers to a procedure whereby encountering with one stimulus affects a reaction to a succeeding stimulus, in the absence of conscious intention or guidance. For example, the world NURSE is acknowledged more promptly following the word DOCTOR.  

Priming can be semantic, perceptual, or conceptual. Priming functions best when the two stimuli are in the similar modality, For example, visual priming functions best with visual hints and verbal priming functions best with verbal hints. However, priming also takes place among the modalities or between semantically associated words as nurse and doctor.
