The founder of rational emotive behavior therapy is Albert Ellis. Rational Emotive Behavior Therapy (REBT), created by Ellis, is a form of cognitive-behavioral therapy that helps individuals identify and challenge their self-defeating beliefs, enabling them to lead more fulfilling lives.
In contrast to the perspectives of Albert Ellis, Max Wertheimer would have most likely agreed with the statement that perceptual phenomena are best understood as a combination of their components. This perspective is aligned with the Gestalt psychology, which emphasizes the holistic nature of perception, as opposed to breaking it down into individual elements. Gestalt psychology views psychological phenomena as organized, structured wholes.
