In psychology, we learn about something called the “absolute threshold.” This is the point where we start to notice really faint things, like a whisper or a dim light. Once we can notice something more than half the time, we say it’s “conscious.” But what about things that are too faint to notice, like a sound so soft you can’t hear it? These are called “subliminal stimuli,” and they’re interesting because they can still affect how we think and act, even though we don’t realize it.<\/p>\n
