In Duncker's terms, the participants were "fixated" on the box's normal function of holding thumbtacks and could not re-conceptualize it in a manner that allowed them to solve the problem. Contrary to the examinator's expectations, the student responded with a series of completely different answers. For these two groups, 55% and 47% were able to solve the problem effectively. The authors concluded that students' performance was contingent on their representation of the lexical concept "box" rather than instructional manipulations. The concept of functional fixedness originated in Gestalt Psychology, which is a movement in psychology that emphasizes wholistic processing where the whole is seen as being separate from the sum of its parts. This mental shortcut allows people to speedily solve recurring problems. Duncker's experiment lead to a concept, functional fixedness, that obligingly fit with his philosophy of psychology.  They examined the inclusion of examples of inappropriate elements, by explicitly depicting problematic aspects of the problem presented to the students through example designs. In the fixated condition, participants were presented with instructions, a design, and problems they should be aware of. Duncker originally presented this test in his thesis on problem-solving tasks at Clark University. In a follow-up experiment, all the nouns except "box" were underlined and similar results were produced. McCaffrey, T. (2012). Similarly, whenever you are faced with a design problem, resist the urge to immediately jump into brainstorming solutions. The experiment was a 2x2 design where conditions: "task contexts" (type and format) vs. "prior knowledge" (specific vs. general) were attested. The object may be familiar from the subject's past experience or from previous tasks within an experiment. Publication Date. Practice overcoming functional fixedness whenever possible: Use a thin coin to tighten a screw instead of reaching for a screwdriver; open a package with your car key instead of a box cutter; or think like The Little Mermaid and make a hair comb out of a fork! Using the matches, melt the bottom part of each candle and then use the hot wax to stick the candle to the matchbox. 21-22 etc. To see alternative, innovative solutions more easily, reframe the design problem. Proceedings of the 19th ACM Conference on Computer-Supported Cooperative Work & Social Computing, 1214-1222. What is functional fixedness? Reproduced in entirety in: Jim Williams (1992). Watch Queue Queue Introduction to Functional Fixedness. Experimental paradigms typically involve solving problems in novel situations in which the subject has the use of a familiar object in an unfamiliar context. A study now nearing completion involves both of these lines of experimentation. Investigators examined in two experiments "whether the inclusion of examples with inappropriate elements, in addition to the instructions for a design problem, would produce fixation effects in students naive to design tasks". (2000). J Exp Psychol. Reproduced in entirety in: Skwire, David (1994). In the candle experiment, 5-year-olds were better at seeing alternative uses for objects, which affected how they viewed the overall problem and thus how they approached solving it. Subscribe to the weekly newsletter to get notified about future articles. Therefore, there is a need to overcome the prototype in order to avoid functional fixedness.  Calandra's essay, "Angels on a Pin", was published in 1959 in Pride, a magazine of the American College Public Relations Association. Latour performed an experiment researching this by having software engineers analyze a fairly standard bit of code—the quicksort algorithm—and use it to create a partitioning function. More recently, Frank and Ramscar (2003) gave a written version of the candle problem to undergraduates at Stanford University. The majority of people suffer from functional fixedness. (1994). Source. Two objects of medium rank were so used in another experiment; and one high and one medium were used in a third. When given the abstracted problem, participants in the study were able to identify remotely related, yet potentially relevant domains of expertise such as contortionism, landscaping, carpentry, and Japanese aesthetics. Glucksberg, Sam: New York U. Three of Duncker's experiments on functional fixedness were repeated in this study. The ability to overcome functional fixedness was contingent on having a flexible representation of the word box which allows students to see that the box can be used when attaching a candle to a wall. Functional fixedness is this inability to see a hammer's use as anything other than for pounding nails; the person couldn't think to use the hammer in a way other than in its conventional function. Due to functional fixedness, you might think of only one way to directly use the thumbtacks. In a recent study, preliminary evidence supporting the universality of functional fixedness was found. The test was created by Gestalt psychologist Karl Duncker and published posthumously in 1945. In this reframed problem, the surface features of power strips, plugs, and outlets were stripped away to avoid functional fixedness. (1951). Another famous experiment like this is the Duncker Candle Box: Functional Fixedness in Puzzle Design. Subscribe to our Alertbox E-Mail Newsletter: The latest articles about interface usability, website design, and UX research from the Nielsen Norman Group. Remote Ideation: Synchronous or Asynchronous? The inability to recognize alternative approaches and uses of elements constrains creativity, and thus limits ideation and problem solving. After training, participants attempted to solve five functional fixedness problems. The problem format and the structural type of analog presentation showed the highest positive transference to problem solving. Once the candles are attached to the box, use the thumbtacks to stick the box to the wall. Functional fixedness is practical in everyday life and crucial in building expertise and specialization in fields where it’s important to come up with quick solutions. 1. Research has found that when people look for inspiration from distant domains, they generate more creative solutions than when they consider only domains closely related to the original, non-abstracted representation of the problem. Duncker found that participants tried to attach the candle directly to the wall with the tacks, or to glue it to the wall by melting it. Functional fixedness literature also shows that subtle linguistic manipulations can modulate functional fixedness. German, T. P., and Defeyter, M. (2000). Functional fixedness stops us from seeing alternative solutions and makes problem solving more difficult. Functional fixedness is based on a mental set, or a specific way of looking at a problem. Karl Duncker defined functional fixedness as being a mental block against using an object in a new way that is required to solve a problem. They tested non-expert participants on three problem conditions: with standard instruction, fixated (with inclusion of problematic design), and defixated (inclusion of problematic design accompanied with helpful methods). Immunity to Functional Fixedness in Young Children. However, it also prevents them from seeing alternate solutions to problems. In the classic functional-fixedness experiment, participants are given a candle, a matchbook, and a box of tacks and are asked to affix the candle to a vertical surface so that it would be able to burn. Doing the same thing the same way; 2. Summary: People’s blindness to alternate uses of objects limits their problem-solving capabilities and stifles creativity. "Does my current description imply a use?" The more we’ve practiced a solution, the harder it is to see alternative ones. This video is unavailable. Carnevale, Peter J.  This "block" limits the ability of an individual to use components given to them to complete a task, as they cannot move past the original purpose of those components. Functional Fixedness is an important concern in the design of adventure puzzles in which the player must gather and use items from the environment, especially when these are everyday objects. "Functional Fixedness as related to problem solving: A repetition of three experiments". While this is an efficient way for our minds to understand the world, it can impair innovation. Adamson, R.E. Functional fixedness is a cognitive bias that strongly associates an object with its most common use. Watch Queue Queue. 2, 1969, p. 13. ") According to Wikipedia, functional fixedness is a cognitive bias that limits a person to use an object only in the way it is traditionally used. Encouraging “Outside-the-box” Thinking in Crowd Innovation Through Identifying Domains of Expertise. In many cases, any heavy object would do the job, and yet we succumb to the need to use the most traditional tool to complete the task. These answers were also correct, yet none of them proved the student's competence in the specific academic field being tested. Affiliation. Reproduced in entirety, in German, in: Otto F. Kernberg (2005). As with many ailments, the first step to overcoming functional fixedness is acknowledging the problem. Replication studies using Duncker’s original experiments on functional fixedness (similar to the candle problem, where the box was pre-utilized as a container for tacks and not offered as a unique resource) show using a resource in a particular way in the past can promote functional fixedness. It has been argued that this is because at age 5, any goal to be achieved with an object is equivalent to any other goal. 228-229; paraphrased in Herson, pp. Two objects with high rankings were used in a functional fixedness experiment, each in turn being the fixed object. Journal of Experimental Psychology , 44 , 288–293. The concept of functional fixedness originated in Gestalt psychology, a movement in psychology that emphasizes holistic processing. So, describe it more generically as a string. In "The Disposable Spill-Proof Coffee Cup Problem", adapted from Janson & Smith, 1991, participants were asked to construct as many designs as possible for an inexpensive, disposable, spill-proof coffee cup. 15 no. The study tested the Shuar, hunter-horticulturalists of the Amazon region of Ecuador, and compared them to a control group from an industrial culture. A comprehensive study exploring several classical functional fixedness experiments showed an overlying theme of overcoming prototypes. Since "interwoven fibrous strands" does not imply a use, I can stop working on wick and start working on wax. In the classic functional-fixedness experiment, participants are given a candle, a matchbook, and a box of tacks and are asked to affix the candle to a vertical surface so that it would be able to burn. Two tasks were assessed to participants for the study: the box task, where participants had to build a tower to help a character from a fictional storyline to reach another character with a limited set of varied materials; the spoon task, where participants were also given a problem to solve based on a fictional story of a rabbit that had to cross a river (materials were used to represent settings) and they were given varied materials including a spoon. Carnevale (1998) suggests analyzing the object and mentally breaking it down into its components.
