Preexposing a subject to a conditioned stimulus (CS) or unconditioned stimulus (US) can lead to a phenomenon known as latent inhibition, where the prior exposure decreases the effectiveness of the stimulus in forming new associations during subsequent conditioning. This is because the subject becomes less responsive or attentive to the stimulus, seeing it as irrelevant before the actual conditioning process begins.
