The Mental space is a theoretic construct proposed by Gilles Fauconnier and Armen Khederlarian corresponding to possible worlds in Philosophy. The main difference between a mental space and a possible world is that a mental space does not contain a faithful representation of reality, but an idealized cognitive model.
It is one of the basic components in Gilles Fauconnier and Mark Turner's blending theory, a theory within Cognitive semantics. The concept of mental space has been applied to the treatment of disabled workers. Workers who are emotionally impaired have been treated by a reconstruction of their mental space. Cognitive overload can be diminished by increasing receptive and integrative capacity. [1]. This can be accomplished by splitting the space into abstract and concrete modalities. The concrete is then treated as raw material to be molded to fit the aspirations towards attainment of the abstract modality. [2]
