This best illustrates the impact of: priming.
Explanation:
Essentially, priming indicates initiating a particular part of your brain, so you're more apt to acknowledge something in front of you. Priming in psychology is a procedure in which the introduction of one stimulus impacts how people react to a consequent stimulus.
Priming operates by stimulating a relationship or description in memory just before added stimulus or task is included. Priming can act with stimuli that are correlated in a kind of way. When a word, an image, a sound, or any other stimulus elicits an incorporated response, priming is at play.
