Wolfgang Kohler’s experiment with Sultan the chimpanzee is considered to be one of the most influential studies in psychology. It demonstrated the concept of insight and showed how animals can be capable of solving complex problems without trial and error. So the correct option is (d).
Kohler considered this sudden solving of the problem to be evidence of insight. Insight is the ability to solve a problem without trial and error and often involves a sudden “aha” moment. For example, in the case of Sultan, he was seemingly able to recognize the connection between the two sticks and how they could be used to reach the banana.
Kohler’s experiment and the concept of insight has been studied extensively over the years. It has become an important part of the field of psychology and has been used to explain a wide variety of phenomena from human behavior to artificial intelligence. In addition, insight has been used to explain the evolution of complex behaviors in animals, such as tool use.
