Answer to Question 1
Insight is a distinctive and sometimes seemingly sudden understanding of a problem or of a strategy that aids in solving the problem. Often, an insight involves reconceptualizing a problem or a strategy in a totally new way. Insight often involves detecting and combining relevant old and new information to gain a novel view of the problem or of its solution. Although insights may feel as though they are sudden, they are often the result of much prior thought and hard work. Without this work, the insight never would have occurred. Insight can be involved in solving well-structured problems, but it more often is associated with the rocky and twisting path to solution that characterizes ill- structured problems. For many years, psychologists interested in problem solving have been trying to figure out the true nature of insight.
Answer to Question 2
Transfer is any carryover of knowledge or skills from one problem situation to another. Transfer can be either negative or positive. Negative transfer occurs when solving an earlier problem makes it harder to solve a later one. Sometimes an early problem gets an individual on a wrong track. Positive transfer occurs when the solution of an earlier problem makes it easier to solve a new problem. That is, sometimes the transfer of a mental set can be an aid to problem solving. For instance, one may transfer early math skills, such as addition, to advanced math problems of the kinds found in algebra or physics.
