Answer:
subliminal differences
Explanation:
The meaning of subliminal is something that is difficult to feel and explain; but may be remembered due to constant repetition.
Subliminal messages are stimuli that lie below our threshold of conscious awareness.
Subliminal differences manipulate our minds and modify our behaviors.
Importantly, research on action priming has shown that subliminal stimuli can trigger only actions a receiver of the message plans to perform.
