The need for recognition is contemplated within the needs of the human being. Abraham Maslow explained it that way in his well-known theory, giving him a higher ranking within the pyramid of human needs.
As masterfully pointed out by @chbartist, in any kind of relationship it is necessary to make use of compliments. This use must, in the first instance, be timely. An untimely recognition loses its motivating effect.
Second, you must be honest if you present build a solid rapport between the people involved. The compliments must respond to a higher level in achieving the objectives. Giving compliments as part of a simple formality, end up affecting the credibility between the parties.
Finally I will quote an expression that I have heard in the managerial field which I think is great and applicable in any context of our public relations: "Recognize in public, ricrimina in private".
Greetings and happy weekend to all!
