This can involve testing, reviewing, or comparing results against established criteria. In psychology, validation refers to recognizing and affirming a person's feelings or experiences. It helps individuals feel understood and accepted, which can improve emotional well-being. Techniques for validation can include active listening and expressing empathy, making it an essential skill in personal relationships and therapeutic settings.
