What were the basic ideas and who were the important people behind the early approaches known as Gestalt psychoanalysis and behaviorism?

Gestalt psychoanalysis focused on understanding human experience as a whole rather than breaking it down into parts, with key figures being Max Wertheimer, Kurt Koffka, and Wolfgang Köhler. Behaviorism, on the other hand, emphasized observable behavior and the influence of the environment on behavior, with important figures including John B. Watson and B.F. Skinner.
