Functional fixedness is a cognitive bias that limits a person to using an object only in the way it is traditionally used.The concept of functional fixedness originated in Gestalt Psychology, a movement in psychology that emphasizes holistic processing.herefore, there is a need to overcome the prototype in order to avoid functional fixedness. Carnevale (1998) suggests analyzing the object and mentally breaking it down into its components. After that is completed, it is essential to explore the possible functions of those parts.
In biology, optimality models are a tool used to evaluate the costs and benefits of different organismal features, traits, and characteristics, including behavior, in the natural world. This evaluation allows researchers to make predictions about an organisms's optimal behavior or other aspects of its phenotype. Optimality modeling is the modeling aspect of optimization theory. It allows for the calculation and visualization of the costs and benefits that influence the outcome of a decision, and contributes to an understanding of adaptations. The approach based on optimality models in biology is sometimes called optimality theory. Optimal behavior is defined as an action that maximizes the difference between the costs and benefits of that decision. Three primary variables are used in optimality models of behavior: decisions, currency, and constraints.
