Functional fixedness

Is functional fixedness universal?

Researchers have investigated whether functional fixedness is affected by culture.

In a recent study, preliminary evidence supporting the universality of functional fixedness was found (German & Barret, 2005). The study's purpose was to test if individuals from non-industrialized societies, specifically with low exposure to "high-tech" artifacts, demonstrated functional fixedness. The study tested the Shuar, hunter-horticulturalists of the Amazon region of Ecuador, and compared them to a control group from an industrial culture.

The Shuar community had only been exposed to a limited amount of industrialized artifacts, such as machete, axes, cooking pots, nails, shotguns, and fishhooks, all considered "low-tech". 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. In the box-task, participants were slower to select the materials than participants in control conditions, but no difference in time to solve the problem was seen. In the spoon task, participants were slower in selection and completion of task. Results showed that Individuals from non-industrial ("technologically sparse cultures") were susceptible to functional fixedness. They were faster to use artifacts without priming than when design function was explained to them. This occurred even though participants were less exposed to industrialized manufactured artifacts, and that the few artifacts they currently use were used in multiple ways regardless of their design.
