===Functional Fixedness===
===Fufreshener'''[[Functional fixedness]]''' is a specific form of mental set and fixation, which was alluded to earlier in the Maier experiment, and furthermore it is another way in which cognitive bias can be seen throughout daily life. Tim German and Clark Barrett describe this barrier as the fixed design of an object hindering the individual's ability to see it serving other functions. In more technical terms, these researchers explained that “[s]ubjects become “fixed” on the design function of the objects, and problem solving suffers relative to control conditions in which the object’s function is not demonstrated.”<ref>German, Tim, P., and Barrett, Clark., H. Functional fixedness in a technologically sparse culture. University of California, Santa Barbara. American psychological society. 16 (1), 2005.</ref> Functional fixedness is defined as only having that primary function of the object itself hinder the ability of it serving another purpose other then its original function. In research that highlighted the primary reasons that young children are immune to functional fixedness, it was stated that “functional fixedness...[is when]subjects are hindered in reaching the solution to a problem by their knowledge of an object’s conventional function.”<ref>German, Tim, P., Defeyter, Margaret A. Immunity to functional fixedness in young children. University of Essex, Colchester, England. Psychonomic Bulletin and Review. 7 (4), 2000.</ref> Furthermore, it is important to note that functional fixedness can be easily expressed in commonplace situations. For instance, imagine the following situation: a man sees a bug on the floor that he wants to kill, but the only thing in his hand at the moment is a can of air freshener. If the man starts looking around for something in the house to kill the bug with instead of realizing that the can of air freshener could in fact be used not only as having its main function as to freshen the air, he is said to be experiencing functional fixedness. The man’s knowledge of the can being served as purely an air freshener hindered his ability to realize that it too could have been used to serve another purpose, which in this instance was as an instrument to kill the bug. Functional fixedness can happen on multiple occasions and can cause us to have certain cognitive biases. If we only see an object as serving one primary focus than we fail to realize that the object can be used in various ways other than its intended purpose. This can in turn cause many issues with regards to problem solving. Common sense seems to be a plausible answer to functional fixedness. One could make this argument because it seems rather simple to consider possible alternative uses for an object. Perhaps using common sense to solve this issue could be the most accurate answer within this context. With the previous stated example,it seems as if it would make perfect sense to use the can of air freshener to kill the bug rather than to search for something else to serve that function but, as research shows, this is often not the case.
Functional fixedness limits the ability for people to solve problems accurately by causing one to have a very narrow way of thinking. Functional fixedness can be seen in other types of learning behaviors as well. For instance, research has discovered the presence of functional fixedness in many educational instances. Researchers Furio, Calatayud, Baracenas, and Padilla stated that “... functional fixedness may be found in learning concepts as well as in solving chemistry problems.”<ref>Furio, C., Calatayud, M. L., Baracenas, S, L., and Padilla, O, M., Functional fixedness and functional reduction as common sense reasonings in chemical equilibrium and in geometry and polarity of molecules. Valencia, Spain. Science Education. 84. (5), 2000.</ref> There was more emphasis on this function being seen in this type of subject and others.
