Candle Problem (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The candle problem or candle task, also known as Duncker's candle problem, is a cognitive performance test, measuring the influence of functional fixedness on a participant's problem solving capabilities. The test was created by Gestalt psychologist Karl Duncker and published posthumously in 1945. Duncker originally presented this test in his thesis on problem solving tasks at Clark University. The test presents the participant with the following task: how to fix a lit candle on a wall (a cork board) in a way so the candle wax won't drip onto the table below.
