Yes, research has demonstrated effects of subliminal stimuli in controlled tasks. These studies help explain why information outside conscious awareness is an interesting part of psychology. Evidence for a particular audio program and personal goal is a more specific question.
What subliminal priming research shows
In a study by Bermeitinger and colleagues, brand logos were presented subliminally during a computer game. Tired participants subsequently consumed more of the dextrose brand whose logo had been presented. The pattern depended on their motivational state.
This was a study of brief visual cues and a particular choice. It demonstrates an effect under those conditions; it doesn't test repeated listening to an affirmation recording.
What has been studied in self-help audio?
A double-blind study by Greenwald and colleagues tested memory and self-esteem tapes and did not find the claimed specific effects after a month. Those findings concern the recordings and outcomes tested. Our programs haven't been clinically validated by these studies.
How we help you choose and use a recording
Our work brings goal-focused scripts together with audio production. You can read sample affirmations and hear available previews when choosing a finished program. With Custom, you review the wording before recording; with Studio, you create the script and mix yourself.
Use the program comparison to find the approach that suits you. If you'd like to continue reading about the research, our research page gathers further material.
