In 1984, Louise Hay published You Can Heal Your Life, a guide to healing the thoughts and beliefs which psychologically support illnesses. Hay’s affirmations are designed to help the user re-program their thought patterns so that the harmful or negative beliefs which support the illness can be replaced with healing or positive beliefs which can remove the barrier to healing.
Affirmations are also referred to in Neuro-Linguistic Programming (NLP), which was developed in the early 1970s by John Grinder and Richard Bandler at the University of California at Santa Cruz.
In the 1980's and 1990's, Tony Robbins popularized the term Neuro Associative Conditioning “NAC,” which shared many similarities with NLP.
