Which concept describes the belief that there are strictly defined functions with no alternate functions?

The concept that describes the belief that there are strictly defined functions with no alternate functions is functional fixedness. This psychological phenomenon occurs when an individual is unable to see beyond the traditional use of an object or a concept, hence limiting their ability to solve problems creatively. For instance, if someone sees a hammer solely as a tool for driving nails, they may struggle to consider its potential use for other tasks, such as a paperweight or a lever. This narrow view can hinder problem-solving and the generation of innovative solutions.

Functional fixedness is particularly significant in cognitive psychology as it illustrates how preconceived mental frameworks can restrict thinking and creativity. The presence of functional fixedness can lead to challenges in overcoming obstacles or finding alternative methods to achieve goals, underscoring its importance in understanding cognitive processes.
