Verified step by step guidance

1. Understand the concept of insight in cognitive psychology: Insight refers to a sudden realization or 'aha' moment when a solution to a problem becomes clear, often after a period of impasse or unsuccessful attempts.
2. Recognize that insight is typically contrasted with analytical problem solving, which is gradual and step-by-step, whereas insight is sudden and often unexpected.
3. Consider the role of prior knowledge and experience: Insight can be influenced by what a person already knows, as prior knowledge can help restructure the problem or trigger the sudden solution.
4. Review empirical research findings: Studies show that insight problems are not necessarily solved more quickly than non-insight problems; instead, the key feature is the suddenness of the solution rather than the speed.
5. Conclude that the statement 'Insight often occurs suddenly after a period of unsuccessful problem solving' aligns with research, highlighting the characteristic suddenness and the typical struggle before the insight moment.
