 In fact, the early experimental work of the Gestaltists in Germany marks the beginning of the scientific study of problem solving.Later this experimental work continued through the 1960s and early 1970s with research conducted on relatively simple (but novel for participants) laboratory tasks of problem solving.Given Gestalt psychology's focus on the whole, it was natural for Gestalt psychologists to study problem solving from the perspective of insight, seeking to understand the process by which organisms sometimes suddenly transition from having no idea how to solve a problem to instantly understanding the whole problem and its solution.
