Answer:
subliminal stimuli or subliminal messages
Explanation:
Subliminal stimuli are stimuli that affect sensors below the conscious perception of the person. The idea is that sending these kinds of stimuli or messages can support a person's subconscious perception and thoughts, and affect a person's conscious decision making in that way.
This idea has been used vastly for marketing purposes and its persuasive use, with the idea that a person that is subject to subliminal stimuli will consciously end up consuming the product displayed before them.
However, scientific researches haven't yet surely confirmed the effectiveness of this method behind the placebo effect.
