In the context of insight learning experiments conducted by Gestalt psychologist Wolfgang Köhler on the chimpanzee 'Sultan', which of the following statements presents the most scientific and logical explanation of the cognitive nature of learning and its functioning?

According to Gestalt psychology, learning is not merely based on mechanics or trial-and-error, but depends on cognitive restructuring. Wolfgang Köhler proved through his experiments that when an organism faces a problem, it observes the entire situation directly (Gestalt perception) and suddenly experiences an 'Aha! Moment', thereby finding a holistic solution to the problem, which is known as the theory of insight.
