Concept:The theory of insight was developed by Gestalt psychologists. They believed learning happens through sudden understanding of relationships, not by trial and error or conditioning.
Explanation:Gestalt theory sees learning as an organized whole. The word "Gestalt" means a unified pattern. Learning occurs when the learner suddenly sees how parts fit together — this is insight.
It is not random or gradual. It involves understanding the whole situation. Gestalt psychologists focused on perception and problem-solving.

Thus, the theory of insight belongs to Gestalt psychologists.
